release: cut the v10.0.1 release

docs commits are sometimes trivial (e.g. an obvious typo fix) and in such cases its very
akward to to write up 100 chars worth of text about why this typo fix is the best thing in the
world and why it is so important and crucial that we must know why we are fixing the typo
at all. After all most typos are not just typos. Or are they? We'll shall see...

-# fix(ngcc): ensure lockfile is removed when `analyzeFn` fails
-#
-# Previously an error thrown in the `analyzeFn` would cause the ngcc process to exit immediately
-# without removing the lockfile, and potentially before the unlocker process had been successfully
-# spawned resulting in the lockfile being orphaned and left behind.
-#
-# Now we catch these errors and remove the lockfile as needed.

-# feat(bazel): simplify ng_package by dropping esm5 and fesm5
-#
-# esm5 and fesm5 distributions are no longer needed and have been deprecated in the past.
-#
-# https://v9.angular.io/guide/deprecations#esm5-and-fesm5-code-formats-in-angular-npm-packages
-#
-# This commit modifies ng_package to no longer distribute these two formats in npm packages built by
-# ng_package (e.g. @angular/core).
-#
-# This commit intentionally doesn't fully clean up the ng_package rule to remove all traces of esm5
-# and fems5 build artifacts as that is a bigger cleanup and currently we are narrowing down the
-# scope of this change to the MVP needed for v10, which in this case is 'do not put esm5 and fesm5'
-# into the npm packages.
-#
-# More cleanup to follow: https://angular-team.atlassian.net/browse/FW-2143
-#
-# BREAKING CHANGE: esm5 and fesm5 format is no longer distributed in Angular's npm packages e.g.
-# @angular/core
-#
-# Angular CLI will automatically downlevel the code to es5 if differential loading is enabled in the
-# Angular project, so no action is required from Angular CLI users.
-#
-# If you are not using Angular CLI to build your application or library, and you need to be able to
-# build es5 artifacts, then you will need to downlevel the distributed Angular code to es5 on your
-# own.

 ```
 
-The `header` is mandatory and must conform to the [Commit Message Header](#commit-header) format.
+The **header** is mandatory and the **scope** of the header is optional.
 
-The `body` is mandatory for all commits except for those of scope "docs".
-When the body is required it must be at least 20 characters long.
+Any line of the commit message cannot be longer than 100 characters! This allows the message to be easier
+to read on GitHub as well as in various git tools.
 
-The `footer` is optional.
+The footer should contain a [closing reference to an issue](https://help.github.com/articles/closing-issues-via-commit-messages/) if any.

-##### Summary
-
-Use the summary field to provide a succinct description of the change:
+### Subject
+The subject contains a succinct description of the change:
 
 * use the imperative, present tense: "change" not "changed" nor "changes"
 * don't capitalize the first letter
 * no dot (.) at the end
 
+### Body
+Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes".
+The body should include the motivation for the change and contrast this with previous behavior.
 
-#### Commit Message Body
+### Footer
+The footer should contain any information about **Breaking Changes** and is also the place to
+reference GitHub issues that this commit **Closes**.
 
-Just as in the summary, use the imperative, present tense: "fix" not "fixed" nor "fixes".
-
-Explain the motivation for the change in the commit message body. This commit message should explain _why_ you are making the change.
-You can include a comparison of the previous behavior with the new behavior in order to illustrate the impact of the change.
-
-
-#### Commit Message Footer
-
-The footer can contain information about breaking changes and is also the place to reference GitHub issues, Jira tickets, and other PRs that this commit closes or is related to.
-
-```
-BREAKING CHANGE: <breaking change summary>
-<BLANK LINE>
-<breaking change description + migration instructions>
-<BLANK LINE>
-<BLANK LINE>
-Fixes #<issue number>
-```
-
-Breaking Change section should start with the phrase "BREAKING CHANGE: " followed by a summary of the breaking change, a blank line, and a detailed description of the breaking change that also includes migration instructions.
-
-
-### Revert commits
-
-If the commit reverts a previous commit, it should begin with `revert: `, followed by the header of the reverted commit.
-
-The content of the commit message body should contain:
-
-- information about the SHA of the commit being reverted in the following format: `This reverts commit <SHA>`,
-- a clear description of the reason for reverting the commit message.
+**Breaking Changes** should start with the word `BREAKING CHANGE:` with a space or two newlines. The rest of the commit message is then used for this.
 
+A detailed explanation can be found in this [document][commit-message-format].

-## Attribute binding
-
-Set the value of an attribute directly with an **attribute binding**. This is the only exception to the rule that a binding sets a target property and the only binding that creates and sets an attribute.
-
-Usually, setting an element property with a [property binding](guide/property-binding)
-is preferable to setting the attribute with a string. However, sometimes
-there is no element property to bind, so attribute binding is the solution.
-
-Consider the [ARIA](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA) and
-[SVG](https://developer.mozilla.org/en-US/docs/Web/SVG). They are purely attributes, don't correspond to element properties, and don't set element properties. In these cases, there are no property targets to bind to.
-
-Attribute binding syntax resembles property binding, but
-instead of an element property between brackets, start with the prefix `attr`,
-followed by a dot (`.`), and the name of the attribute.
-You then set the attribute value, using an expression that resolves to a string,
-or remove the attribute when the expression resolves to `null`.
-
-One of the primary use cases for attribute binding
-is to set ARIA attributes, as in this example:

-
-<code-example language="html">
-  &lt;tr&gt;&lt;td colspan="{{1 + 1}}"&gt;Three-Four&lt;/td&gt;&lt;/tr&gt;
-</code-example>
-
-You'd get this error:

-  Can't bind to 'colspan' since it isn't a known native property
-</code-example>
-
-As the message says, the `<td>` element does not have a `colspan` property. This is true
-because `colspan` is an attribute&mdash;`colSpan`, with a capital `S`, is the
-corresponding property. Interpolation and property binding can set only *properties*, not attributes.
-

-
-Here's how to set the `class` attribute without a binding in plain HTML:
-
-```html
-<!-- standard class attribute setting -->
-<div class="foo bar">Some text</div>
-```
-
-You can also add and remove CSS class names from an element's `class` attribute with a **class binding**.
-
-To create a single class binding, start with the prefix `class` followed by a dot (`.`) and the name of the CSS class (for example, `[class.foo]="hasFoo"`).
-Angular adds the class when the bound expression is truthy, and it removes the class when the expression is falsy (with the exception of `undefined`, see [styling delegation](#styling-delegation)).
-
-To create a binding to multiple classes, use a generic `[class]` binding without the dot (for example, `[class]="classExpr"`).
-The expression can be a space-delimited string of class names, or you can format it as an object with class names as the keys and truthy/falsy expressions as the values.
-With object format, Angular will add a class only if its associated value is truthy.
-
-It's important to note that with any object-like expression (`object`, `Array`, `Map`, `Set`, etc), the identity of the object must change for the class list to be updated.
-Updating the property without changing object identity will have no effect.
-
-If there are multiple bindings to the same class name, conflicts are resolved using [styling precedence](#styling-precedence).

-The property will be set to the value of the bound expression, which is normally a string.

-
-</div>
-
-If there are multiple styles you'd like to toggle, you can bind to the `[style]` property directly without the dot (for example, `[style]="styleExpr"`).
-The expression attached to the `[style]` binding is most often a string list of styles like `"width: 100px; height: 100px;"`.
-
-You can also format the expression as an object with style names as the keys and style values as the values, like `{width: '100px', height: '100px'}`.

-## Styling Precedence
-
-A single HTML element can have its CSS class list and style values bound to multiple sources (for example, host bindings from multiple directives).
-
-When there are multiple bindings to the same class name or style property, Angular uses a set of precedence rules to resolve conflicts and determine which classes or styles are ultimately applied to the element.
-
-<div class="alert is-helpful">
-<h4>Styling precedence (highest to lowest)</h4>

-1. Template bindings

-
-</div>
-
-The more specific a class or style binding is, the higher its precedence.
-
-A binding to a specific class (for example, `[class.foo]`) will take precedence over a generic `[class]` binding, and a binding to a specific style (for example, `[style.bar]`) will take precedence over a generic `[style]` binding.
-
-<code-example path="attribute-binding/src/app/app.component.html" region="basic-specificity" header="src/app/app.component.html"></code-example>
-
-Specificity rules also apply when it comes to bindings that originate from different sources.
-It's possible for an element to have bindings in the template where it's declared, from host bindings on matched directives, and from host bindings on matched components.
-
-Template bindings are the most specific because they apply to the element directly and exclusively, so they have the highest precedence.
-
-Directive host bindings are considered less specific because directives can be used in multiple locations, so they have a lower precedence than template bindings.
-
-Directives often augment component behavior, so host bindings from components have the lowest precedence.
-
-<code-example path="attribute-binding/src/app/app.component.html" region="source-specificity" header="src/app/app.component.html"></code-example>
-
-In addition, bindings take precedence over static attributes.
-
-In the following case, `class` and `[class]` have similar specificity, but the `[class]` binding will take precedence because it is dynamic.
-
-<code-example path="attribute-binding/src/app/app.component.html" region="dynamic-priority" header="src/app/app.component.html"></code-example>
-
-{@a styling-delegation}
-### Delegating to styles with lower precedence
-
-It is possible for higher precedence styles to "delegate" to lower precedence styles using `undefined` values.
-Whereas setting a style property to `null` ensures the style is removed, setting it to `undefined` will cause Angular to fall back to the next-highest precedence binding to that style.
-
-For example, consider the following template:

-<code-example path="attribute-binding/src/app/app.component.html" region="style-delegation" header="src/app/app.component.html"></code-example>
-
-Imagine that the `dirWithHostBinding` directive and the `comp-with-host-binding` component both have a `[style.width]` host binding.
-In that case, if `dirWithHostBinding` sets its binding to `undefined`, the `width` property will fall back to the value of the `comp-with-host-binding` host binding.
-However, if `dirWithHostBinding` sets its binding to `null`, the `width` property will be removed entirely.

-# Binding syntax: an overview
-
-Data-binding is a mechanism for coordinating what users see, specifically
-with application data values.
-While you could push values to and pull values from HTML,
-the application is easier to write, read, and maintain if you turn these tasks over to a binding framework.
-You simply declare bindings between binding sources, target HTML elements, and let the framework do the rest.
-
-<div class="alert is-helpful">
-
-See the <live-example></live-example> for a working example containing the code snippets in this guide.
-
-</div>
-
-Angular provides many kinds of data-binding. Binding types can be grouped into three categories distinguished by the direction of data flow:
-
-* From the _source-to-view_
-* From _view-to-source_
-* Two-way sequence: _view-to-source-to-view_

-Binding types other than interpolation have a **target name** to the left of the equal sign, either surrounded by punctuation, `[]` or `()`,
-or preceded by a prefix: `bind-`, `on-`, `bindon-`.
-
-The *target* of a binding is the property or event inside the binding punctuation: `[]`, `()` or `[()]`.
-
-Every public member of a **source** directive is automatically available for binding.
-You don't have to do anything special to access a directive member in a template expression or statement.
-
-
-### Data-binding and HTML
-
-In the normal course of HTML development, you create a visual structure with HTML elements, and
-you modify those elements by setting element attributes with string constants.
-
-```html
-<div class="special">Plain old HTML</div>
-<img src="images/item.png">
-<button disabled>Save</button>
-```
-
-With data-binding, you can control things like the state of a button:
-
-<code-example path="binding-syntax/src/app/app.component.html" region="disabled-button" header="src/app/app.component.html"></code-example>
-
-Notice that the binding is to the `disabled` property of the button's DOM element,
-**not** the attribute. This applies to data-binding in general. Data-binding works with *properties* of DOM elements, components, and directives, not HTML *attributes*.
-
-{@a html-attribute-vs-dom-property}
-
-### HTML attribute vs. DOM property
-
-The distinction between an HTML attribute and a DOM property is key to understanding
-how Angular binding works. **Attributes are defined by HTML. Properties are accessed from DOM (Document Object Model) nodes.**
-
-* A few HTML attributes have 1:1 mapping to properties; for example, `id`.
-
-* Some HTML attributes don't have corresponding properties; for example, `aria-*`.
-
-* Some DOM properties don't have corresponding attributes; for example, `textContent`.
-
-It is important to remember that *HTML attribute* and the *DOM property* are different things, even when they have the same name.
-In Angular, the only role of HTML attributes is to initialize element and directive state.
-
-**Template binding works with *properties* and *events*, not *attributes*.**
-
-When you write a data-binding, you're dealing exclusively with the *DOM properties* and *events* of the target object.
-
-<div class="alert is-helpful">
-
-This general rule can help you build a mental model of attributes and DOM properties:
-**Attributes initialize DOM properties and then they are done.
-Property values can change; attribute values can't.**
-
-There is one exception to this rule.
-Attributes can be changed by `setAttribute()`, which re-initializes corresponding DOM properties.
-
-</div>
-
-For more information, see the [MDN Interfaces documentation](https://developer.mozilla.org/en-US/docs/Web/API#Interfaces) which has API docs for all the standard DOM elements and their properties.
-Comparing the [`<td>` attributes](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/td) attributes to the [`<td>` properties](https://developer.mozilla.org/en-US/docs/Web/API/HTMLTableCellElement) provides a helpful example for differentiation.
-In particular, you can navigate from the attributes page to the properties via "DOM interface" link, and navigate the inheritance hierarchy up to `HTMLTableCellElement`.
-
-
-#### Example 1: an `<input>`
-
-When the browser renders `<input type="text" value="Sarah">`, it creates a
-corresponding DOM node with a `value` property initialized to "Sarah".
-
-```html
-<input type="text" value="Sarah">
-```
-
-When the user enters "Sally" into the `<input>`, the DOM element `value` *property* becomes "Sally".
-However, if you look at the HTML attribute `value` using `input.getAttribute('value')`, you can see that the *attribute* remains unchanged&mdash;it returns "Sarah".
-
-The HTML attribute `value` specifies the *initial* value; the DOM `value` property is the *current* value.
-
-To see attributes versus DOM properties in a functioning app, see the <live-example name="binding-syntax"></live-example> especially for binding syntax.
-
-#### Example 2: a disabled button
-
-The `disabled` attribute is another example. A button's `disabled`
-*property* is `false` by default so the button is enabled.
-
-When you add the `disabled` *attribute*, its presence alone
-initializes the button's `disabled` *property* to `true`
-so the button is disabled.
-
-```html
-<button disabled>Test Button</button>
-```
-
-Adding and removing the `disabled` *attribute* disables and enables the button.
-However, the value of the *attribute* is irrelevant,
-which is why you cannot enable a button by writing `<button disabled="false">Still Disabled</button>`.
-
-To control the state of the button, set the `disabled` *property*,
-
-<div class="alert is-helpful">
-
-Though you could technically set the `[attr.disabled]` attribute binding, the values are different in that the property binding requires to a boolean value, while its corresponding attribute binding relies on whether the value is `null` or not. Consider the following:
-
-```html
-<input [disabled]="condition ? true : false">
-<input [attr.disabled]="condition ? 'disabled' : null">
-```
-
-Generally, use property binding over attribute binding as it is more intuitive (being a boolean value), has a shorter syntax, and is more performant.
-
-</div>
-
-
-To see the `disabled` button example in a functioning app, see the <live-example name="binding-syntax"></live-example> especially for binding syntax. This example shows you how to toggle the disabled property from the component.
-
-## Binding types and targets
-
-The **target of a data-binding** is something in the DOM.
-Depending on the binding type, the target can be a property (element, component, or directive),
-an event (element, component, or directive), or sometimes an attribute name.
-The following table summarizes the targets for the different binding types.

-## Built-in attribute directives
-
-Attribute directives listen to and modify the behavior of
-other HTML elements, attributes, properties, and components.
-You usually apply them to elements as if they were HTML attributes, hence the name.
-
-Many NgModules such as the [`RouterModule`](guide/router "Routing and Navigation")
-and the [`FormsModule`](guide/forms "Forms") define their own attribute directives.
-The most common attribute directives are as follows:
-
-* [`NgClass`](guide/built-in-directives#ngClass)&mdash;adds and removes a set of CSS classes.
-* [`NgStyle`](guide/built-in-directives#ngStyle)&mdash;adds and removes a set of HTML styles.
-* [`NgModel`](guide/built-in-directives#ngModel)&mdash;adds two-way data binding to an HTML form element.
-
-<hr/>
-
-{@a ngClass}
-
-## `NgClass`
-
-Add or remove several CSS classes simultaneously with `ngClass`.
-
-<code-example path="built-in-directives/src/app/app.component.html" region="special-div" header="src/app/app.component.html"></code-example>
-
-<div class="alert is-helpful">
-
-To add or remove a *single* class, use [class binding](guide/attribute-binding#class-binding) rather than `NgClass`.
-
-</div>
-
-Consider a `setCurrentClasses()` component method that sets a component property,
-`currentClasses`, with an object that adds or removes three classes based on the
-`true`/`false` state of three other component properties. Each key of the object is a CSS class name; its value is `true` if the class should be added,
-`false` if it should be removed.
-
-<code-example path="built-in-directives/src/app/app.component.ts" region="setClasses" header="src/app/app.component.ts"></code-example>
-
-Adding an `ngClass` property binding to `currentClasses` sets the element's classes accordingly:
-
-<code-example path="built-in-directives/src/app/app.component.html" region="NgClass-1" header="src/app/app.component.html"></code-example>
-
-<div class="alert is-helpful">
-
-Remember that in this situation you'd call `setCurrentClasses()`,
-both initially and when the dependent properties change.
-
-</div>
-
-<hr/>
-
-{@a ngStyle}
-
-## `NgStyle`
-
-Use `NgStyle` to set many inline styles simultaneously and dynamically, based on the state of the component.
-
-### Without `NgStyle`
-
-For context, consider setting a *single* style value with [style binding](guide/attribute-binding#style-binding), without `NgStyle`.
-
-<code-example path="built-in-directives/src/app/app.component.html" region="without-ng-style" header="src/app/app.component.html"></code-example>
-
-However, to set *many* inline styles at the same time, use the `NgStyle` directive.
-
-The following is a `setCurrentStyles()` method that sets a component
-property, `currentStyles`, with an object that defines three styles,
-based on the state of three other component properties:
-
-<code-example path="built-in-directives/src/app/app.component.ts" region="setStyles" header="src/app/app.component.ts"></code-example>
-
-Adding an `ngStyle` property binding to `currentStyles` sets the element's styles accordingly:
-
-<code-example path="built-in-directives/src/app/app.component.html" region="NgStyle-2" header="src/app/app.component.html"></code-example>
-
-<div class="alert is-helpful">
-
-Remember to call `setCurrentStyles()`, both initially and when the dependent properties change.
-
-</div>
-
-
-<hr/>
-
-{@a ngModel}
-
-## `[(ngModel)]`: Two-way binding
-
-The `NgModel` directive allows you to display a data property and
-update that property when the user makes changes. Here's an example:
-
-<code-example path="built-in-directives/src/app/app.component.html" header="src/app/app.component.html (NgModel example)" region="NgModel-1"></code-example>
-
-
-### Import `FormsModule` to use `ngModel`
-
-Before using the `ngModel` directive in a two-way data binding,
-you must import the `FormsModule` and add it to the NgModule's `imports` list.
-Learn more about the `FormsModule` and `ngModel` in [Forms](guide/forms#ngModel).
-
-Remember to import the `FormsModule` to make `[(ngModel)]` available as follows:
-
-<code-example path="built-in-directives/src/app/app.module.ts" header="src/app/app.module.ts (FormsModule import)" region="import-forms-module"></code-example>
-
-
-You could achieve the same result with separate bindings to
-the `<input>` element's  `value` property and `input` event:
-
-<code-example path="built-in-directives/src/app/app.component.html" region="without-NgModel" header="src/app/app.component.html"></code-example>
-
-To streamline the syntax, the `ngModel` directive hides the details behind its own `ngModel` input and `ngModelChange` output properties:
-
-<code-example path="built-in-directives/src/app/app.component.html" region="NgModelChange" header="src/app/app.component.html"></code-example>
-
-The `ngModel` data property sets the element's value property and the `ngModelChange` event property
-listens for changes to the element's value.
-
-### `NgModel` and value accessors
-
-The details are specific to each kind of element and therefore the `NgModel` directive only works for an element
-supported by a [ControlValueAccessor](api/forms/ControlValueAccessor)
-that adapts an element to this protocol.
-Angular provides *value accessors* for all of the basic HTML form elements and the
-[Forms](guide/forms) guide shows how to bind to them.
-
-You can't apply `[(ngModel)]` to a non-form native element or a
-third-party custom component until you write a suitable value accessor. For more information, see
-the API documentation on [DefaultValueAccessor](https://angular.io/api/forms/DefaultValueAccessor).
-
-You don't need a value accessor for an Angular component that
-you write because you can name the value and event properties
-to suit Angular's basic [two-way binding syntax](guide/two-way-binding)
-and skip `NgModel` altogether.
-The `sizer` in the
-[Two-way Binding](guide/two-way-binding) section is an example of this technique.
-
-Separate `ngModel` bindings are an improvement over binding to the
-element's native properties, but you can streamline the binding with a
-single declaration using the `[(ngModel)]` syntax:
-
-<code-example path="built-in-directives/src/app/app.component.html" region="NgModel-1" header="src/app/app.component.html"></code-example>
-
-This `[(ngModel)]` syntax can only _set_ a data-bound property.
-If you need to do something more, you can write the expanded form;
-for example, the following changes the `<input>` value to uppercase:
-
-<code-example path="built-in-directives/src/app/app.component.html" region="uppercase" header="src/app/app.component.html"></code-example>
-
-Here are all variations in action, including the uppercase version:

-
-## Built-in _structural_ directives
-
-Structural directives are responsible for HTML layout.
-They shape or reshape the DOM's structure, typically by adding, removing, and manipulating
-the host elements to which they are attached.
-
-This section is an introduction to the common built-in structural directives:
-
-* [`NgIf`](guide/built-in-directives#ngIf)&mdash;conditionally creates or destroys subviews from the template.
-* [`NgFor`](guide/built-in-directives#ngFor)&mdash;repeat a node for each item in a list.
-* [`NgSwitch`](guide/built-in-directives#ngSwitch)&mdash;a set of directives that switch among alternative views.
-
-<div class="alert is-helpful">
-
-The deep details of structural directives are covered in the
-[Structural Directives](guide/structural-directives) guide,
-which explains the following:
-
-* Why you
-[prefix the directive name with an asterisk (\*)](guide/structural-directives#the-asterisk--prefix).
-* Using [`<ng-container>`](guide/structural-directives#ngcontainer "<ng-container>")
-to group elements when there is no suitable host element for the directive.
-* How to write your own structural directive.
-* That you can only apply [one structural directive](guide/structural-directives#one-per-element "one per host element") to an element.
-
-</div>
-
-<hr/>
-
-{@a ngIf}
-
-## NgIf
-
-You can add or remove an element from the DOM by applying an `NgIf` directive to
-a host element.
-Bind the directive to a condition expression like `isActive` in this example.
-
-<code-example path="built-in-directives/src/app/app.component.html" region="NgIf-1" header="src/app/app.component.html"></code-example>
-
-<div class="alert is-helpful">
-
-Don't forget the asterisk (`*`) in front of `ngIf`. For more information
-on the asterisk, see the [asterisk (*) prefix](guide/structural-directives#the-asterisk--prefix) section of
-[Structural Directives](guide/structural-directives).
-
-</div>
-
-When the `isActive` expression returns a truthy value, `NgIf` adds the
-`ItemDetailComponent` to the DOM.
-When the expression is falsy, `NgIf` removes the `ItemDetailComponent`
-from the DOM, destroying that component and all of its sub-components.
-
-
-### Show/hide vs. `NgIf`
-
-Hiding an element is different from removing it with `NgIf`.
-For comparison, the following example shows how to control
-the visibility of an element with a
-[class](guide/attribute-binding#class-binding) or [style](guide/attribute-binding#style-binding) binding.
-
-<code-example path="built-in-directives/src/app/app.component.html" region="NgIf-3" header="src/app/app.component.html"></code-example>
-
-When you hide an element, that element and all of its descendants remain in the DOM.
-All components for those elements stay in memory and
-Angular may continue to check for changes.
-You could be holding onto considerable computing resources and degrading performance
-unnecessarily.
-
-`NgIf` works differently. When `NgIf` is `false`, Angular removes the element and its descendants from the DOM.
-It destroys their components, freeing up resources, which
-results in a better user experience.
-
-If you are hiding large component trees, consider `NgIf` as a more
-efficient alternative to showing/hiding.
-
-<div class="alert is-helpful">
-
-For more information on `NgIf` and `ngIfElse`, see the [API documentation about NgIf](api/common/NgIf).
-
-</div>
-
-### Guard against null
-
-Another advantage of `ngIf` is that you can use it to guard against null. Show/hide
-is best suited for very simple use cases, so when you need a guard, opt instead for `ngIf`. Angular will throw an error if a nested expression tries to access a property of `null`.
-
-The following shows `NgIf` guarding two `<div>`s.
-The `currentCustomer` name appears only when there is a `currentCustomer`.
-The `nullCustomer` will not be displayed as long as it is `null`.

-
-{@a ngFor}
-## `NgFor`
-
-`NgFor` is a repeater directive&mdash;a way to present a list of items.
-You define a block of HTML that defines how a single item should be displayed
-and then you tell Angular to use that block as a template for rendering each item in the list.
-The text assigned to `*ngFor` is the instruction that guides the repeater process.
-
-The following example shows `NgFor` applied to a simple `<div>`. (Don't forget the asterisk (`*`) in front of `ngFor`.)
-

-
-<div class="alert is-helpful">
-
-Don't forget the asterisk (`*`) in front of `ngFor`. For more information
-on the asterisk, see the [asterisk (*) prefix](guide/structural-directives#the-asterisk--prefix) section of
-[Structural Directives](guide/structural-directives).
-
-</div>
-
-You can also apply an `NgFor` to a component element, as in the following example.

-{@a microsyntax}
-
-<div class="callout is-critical">
-<header>*ngFor microsyntax</header>
-
-The string assigned to `*ngFor` is not a [template expression](guide/interpolation). Rather,
-it's a *microsyntax*&mdash;a little language of its own that Angular interprets.
-The string `"let item of items"` means:
-
-> *Take each item in the `items` array, store it in the local `item` looping variable, and
-make it available to the templated HTML for each iteration.*
-
-Angular translates this instruction into an `<ng-template>` around the host element,
-then uses this template repeatedly to create a new set of elements and bindings for each `item`
-in the list.
-For more information about microsyntax, see the [Structural Directives](guide/structural-directives#microsyntax) guide.

-{@a template-input-variable}
-
-{@a template-input-variables}
-
-### Template input variables
-
-The `let` keyword before `item` creates a template input variable called `item`.
-The `ngFor` directive iterates over the `items` array returned by the parent component's `items` property
-and sets `item` to the current item from the array during each iteration.
-
-Reference `item` within the `ngFor` host element
-as well as within its descendants to access the item's properties.
-The following example references `item` first in an interpolation
-and then passes in a binding to the `item` property of the `<app-item-detail>` component.
-
-<code-example path="built-in-directives/src/app/app.component.html" region="NgFor-1-2" header="src/app/app.component.html"></code-example>
-
-For more information about template input variables, see
-[Structural Directives](guide/structural-directives#template-input-variable).
-
-### `*ngFor` with `index`
-
-The `index` property of the `NgFor` directive context
-returns the zero-based index of the item in each iteration.
-You can capture the `index` in a template input variable and use it in the template.
-
-The next example captures the `index` in a variable named `i` and displays it with the item name.
-
-<code-example path="built-in-directives/src/app/app.component.html" region="NgFor-3" header="src/app/app.component.html"></code-example>
-
-<div class="alert is-helpful">
-
-`NgFor` is implemented by the `NgForOf` directive. Read more about the other `NgForOf` context values such as `last`, `even`,
-and `odd` in the [NgForOf API reference](api/common/NgForOf).
-
-</div>
-
-{@a trackBy}
-### *ngFor with `trackBy`
-
-If you use `NgFor` with large lists, a small change to one item, such as removing or adding an item, can trigger a cascade of DOM manipulations. For example, re-querying the server could reset a list with all new item objects, even when those items were previously displayed. In this case, Angular sees only a fresh list of new object references and has no choice but to replace the old DOM elements with all new DOM elements.
-
-You can make this more efficient with `trackBy`.
-Add a method to the component that returns the value `NgFor` should track.
-In this case, that value is the hero's `id`. If the `id` has already been rendered,
-Angular keeps track of it and doesn't re-query the server for the same `id`.
-
-<code-example path="built-in-directives/src/app/app.component.ts" region="trackByItems" header="src/app/app.component.ts"></code-example>
-
-In the microsyntax expression, set `trackBy` to the `trackByItems()` method.
-
-<code-example path="built-in-directives/src/app/app.component.html" region="trackBy" header="src/app/app.component.html"></code-example>
-
-Here is an illustration of the `trackBy` effect.
-"Reset items" creates new items with the same `item.id`s.
-"Change ids" creates new items with new `item.id`s.
-
-* With no `trackBy`, both buttons trigger complete DOM element replacement.
-* With `trackBy`, only changing the `id` triggers element replacement.

-
-{@a ngSwitch}
-## The `NgSwitch` directives
-
-NgSwitch is like the JavaScript `switch` statement.
-It displays one element from among several possible elements, based on a switch condition.
-Angular puts only the selected element into the DOM.
-<!-- API Flagged -->
-`NgSwitch` is actually a set of three, cooperating directives:
-`NgSwitch`, `NgSwitchCase`, and `NgSwitchDefault` as in the following example.
-
- <code-example path="built-in-directives/src/app/app.component.html" region="NgSwitch" header="src/app/app.component.html"></code-example>
-
-<div class="lightbox">
-  <img src="generated/images/guide/built-in-directives/ngswitch.gif" alt="Animation of NgSwitch">
-</div>
-
-`NgSwitch` is the controller directive. Bind it to an expression that returns
-the *switch value*, such as `feature`. Though the `feature` value in this
-example is a string, the switch value can be of any type.
-
-**Bind to `[ngSwitch]`**. You'll get an error if you try to set `*ngSwitch` because
-`NgSwitch` is an *attribute* directive, not a *structural* directive.
-Rather than touching the DOM directly, it changes the behavior of its companion directives.
-
-**Bind to `*ngSwitchCase` and `*ngSwitchDefault`**.
-The `NgSwitchCase` and `NgSwitchDefault` directives are _structural_ directives
-because they add or remove elements from the DOM.
-
-* `NgSwitchCase` adds its element to the DOM when its bound value equals the switch value and removes
-its bound value when it doesn't equal the switch value.
-
-* `NgSwitchDefault` adds its element to the DOM when there is no selected `NgSwitchCase`.
-
-The switch directives are particularly useful for adding and removing *component elements*.
-This example switches among four `item` components defined in the `item-switch.components.ts` file.
-Each component has an `item` [input property](guide/inputs-outputs#input "Input property")
-which is bound to the `currentItem` of the parent component.
-
-Switch directives work as well with native elements and web components too.
-For example, you could replace the `<app-best-item>` switch case with the following.
-
-<code-example path="built-in-directives/src/app/app.component.html" region="NgSwitch-div" header="src/app/app.component.html"></code-example>

-# Creando librerías
-
-Está pagina provee una vista conceptual de como puedes crear y publicar nuevas librerías para extender las funcionalidades de Angular.
-
-Si necesitas resolver el mismo problema en mas de una aplicación (o quiere compartir tu solución con otros desarrolladores), tienes un candidato para una librería.
-Un ejemplo simple puede ser un botón que envía a los usuarios hacia el sitio web de tu empresa, que sería incluido en todas las aplicaciones que tu empresa crea.
-
-## Empezando
-
-Usa el Angular CLI para generar un nuevo esqueleto de librería, en nuevo espacio de trabajo con los siguiente comandos.
-
-<code-example language="bash">
- ng new my-workspace --create-application=false
- cd my-workspace
- ng generate library my-lib
-</code-example>
-
-El comando `ng generate` crea la carpeta `projects/my-lib` en el espacio de trabajo, que contiene un componente y un servicio dentro de un NgModule.
-
-<div class="alert is-helpful">
-
-     Para más detalles sobre como una librería es estructurada, refiérase a los [Archivos de Librería](guide/file-structure#library-project-files) en la sección de [Guía de estructura de archivos](guide/file-structure).
-
-     Puedes usar un modelo de monorepo para usar el mismo espacio de trabajo con multiples proyectos. Véase [Configuración para espacio de trabajo multiproyecto](guide/file-structure#multiple-projects).
-
-</div>
-
-Cuando se genera una nueva librería, el archivo de configuración del espacio de trabajo, `angular.json`, es actualizado con un proyecto de tipo 'library'.
-
-<code-example format="json">
-"projects": {
-  ...
-  "my-lib": {
-    "root": "projects/my-lib",
-    "sourceRoot": "projects/my-lib/src",
-    "projectType": "library",
-    "prefix": "lib",
-    "architect": {
-      "build": {
-        "builder": "@angular-devkit/build-ng-packagr:build",
-        ...
-</code-example>
-
-Puedes crear, probar y comprobar con los comandos de CLI:
-
-<code-example language="bash">
- ng build my-lib
- ng test my-lib
- ng lint my-lib
-</code-example>
-
-Puedes notar que el constructor configurado para el proyecto es diferente que el constructor por defecto para proyectos.
-El constructor, entre otras cosas, asegura que la librería siempre este construida con el [compilador AOT](guide/aot-compiler), sin la necesidad de especificar la bandera `--prod`.
-
-Para hacer el código de la librería reusable debes definir una API pública para ella. Esta "capa de usuario" define que esta disponible para los consumidores de tu librería. Un usuario de tu librería debería ser capaz de acceder a la funcionalidad publica (como NgModules, servicios, proveedores y en general funciones de utilidad) mediante una sola ruta.
-
-La API pública para tu librería es mantenida en el archivo `public-api.ts` en tu carpeta de librería.
-Cualquier cosa exportada desde este archivo se hace publica cuando tu librería es importada dentro de una aplicación.
-Usa un NgModule para exponer los servicios y componentes.
-
-Tu libería debería suministrar documentatión (típicamente en el archivo README) para la instalación y mantenimiento.
-
-## Refactorizando partes de una app dentro de un librería
-
-Para hacer tu solución reusable, necesitas ajustarla para que no dependa del código específico de la aplicación.
-Aquí algunas cosas para considerar al migrar la funcionalidad de la aplicación a una librería.
-
-* Declaraciones tales como componentes y pipes deberían ser diseñados como 'stateless' (sin estado), lo que significa que no dependen ni alteran variables externas. Si tu dependes del estado, necesitas evaluar cada caso y decidir el estado de la aplicación o el estado que la aplicación administraría.
-
-* Cualquier observable al cual los componentes se suscriban internamente deberían ser limpiados y desechados durante el ciclo de vida de esos componentes.
-
-* Los componentes deberían exponer sus interacciones a través de 'inputs' para proporcionar contexto y 'outputs' para comunicar los eventos hacia otros componentes.
-
-* Verifique todas las dependencias internas.
-   * Para clases personalizadas o interfaces usadas en componentes o servicios, verifique si dependen en clases adicionales o interfaces que también necesiten ser migradas.
-   * Del mismo modo, si tu código de librería depende de un servicio, este servicio necesita ser migrado.
-   * Si tu código de librería o sus plantillas dependen de otras librerías (como Angular Material), debes configurar tu librería con esas dependencias.
-
-* Considere como proporcionar servicios a las aplicaciones cliente.
-
-   * Los servicios deberían declarar sus propios proveedores (en lugar de declarar los proveedores en el NgModule o en un componente). Esto le permite al compilador dejar los servicios fuera del 'bundle' si este nunca fue inyectado dentro de la aplicación que importa la librería, véase [proveedores Tree-shakable](guide/dependency-injection-providers#tree-shakable-providers)
-   * Si registras proveedores globales o compartes proveedores a través de múltiples NgModules, usa el [`forRoot()` y `forChild()` como patrones de diseño](guide/singleton-services) proporcionados por el [RouterModule](api/router/RouterModule).
-   * Si tu librería proporciona servicios opcionales que podrían no ser usados por todos las aplicaciones cliente, soporte apropiadamente el 'tree-shaking' para esos casos usando el [patrón de diseño de token ligero](guide/lightweight-injection-tokens).

-{@a integrating-with-the-cli}
-
-## Integración con el CLI usando generación de código con los schematics.
-
-Comúnmente una librería incluye *código reusable* que define componentes, servicios y otros Artefactos de Angular (pipes, directivas y etc.) que tu simplemente importas a un proyecto.
-Una librería es empaquetada dentro de un paquete npm para publicar y compartir.
-
-Este paquete también puede incluir [schematics](guide/glossary#schematic) que proporciona instrucciones para generar o transformar código directamente un tu proyecto, de la misma forma que el CLI crea un nuevo componente genérico con `ng generate component`.
-
-Un 'schematic' empaquetado con una librería puede por ejemplo proporcionar al Angular CLI la información que necesita para generar un componente que configura y usa una particular característica o conjunto de características, definido en la librería.
-
-Un ejemplo de esto es el 'schematic' de navegación de Angular Material el cual configura los CDK's `BreakpointObserver` y lo usa con los componentes `MatSideNav` y `MatToolbar` de Angular Material.
-
-Puedes crear e incluir los siguientes tipos de 'schematics'.
-
-* Incluye un 'schematic' de instalación para que con `ng add` puedas agregar tu libería a un proyecto.
-
-* Incluye un 'schematic' de generación en tu librería para que con `ng generate` puedas hacer scaffolding de sus artefactos (componentes, servicios, pruebas y etc) en un proyecto.
-
-* Incluye un 'schematic' de actualización para que con `ng update` puedas actualizar las dependencias de tu librería y proporcionar migraciones para cambios importantes en un nuevo release.
-
-Lo que incluya tu librería depende de tu tarea.
-Por ejemplo, podrías definir un 'schematic' para crear un desplegable (dropdown) que esta pre-poblado con datos para mostrar como agregarlo a una aplicación.
-Si quieres un desplegable (dropdown) que contendrá valores diferentes cada vez, tu librería podría definir un 'schematic' para crearlo con una configuración dada. Los desarrolladores podrán entonces usar `ng generate` para configurar una instancia para sus propias aplicaciones.
-
-Supón que quieres leer un archivo de configuración y entonces generar una formulario con base a la configuración.
-Si este formulario necesita personalización adicional por parte del desarrollador que esta usando tu librería, esto podría trabajar mejor como un 'schematic'.
-Sin embargo, si el formulario siempre será el mismo y no necesita de mucha personalización por parte de los desarrolladores, entonces podría crear un componente dinámico que tome la configuración y genere el formulario.
-En general, entre más compleja sea personalización, la más util será en enfoque de un 'schematic'.
-
-Para aprender más, véase [Vista general de Schematics](guide/schematics)
-
-## Publicando tu librería
-
-Usa el Angular CLI y el gestor de paquetes npm para construir y publicar tu librería como un paquete npm.
-
-Antes de publicar una librería a NPM, constrúyela usando la bandera `--prod` la cúal usará el compilador y tiempo de ejecución (runtime) más antiguos como 'View Engine' en vez de 'Ivy'.
-
-<code-example language="bash">
-ng build my-lib --prod
-cd dist/my-lib
-npm publish
-</code-example>
-
-Si nunca has publicado un paquete en npm antes, tu debes crear un cuenta. Lee más en [Publicando paquetes npm](https://docs.npmjs.com/getting-started/publishing-npm-packages).
-
-<div class="alert is-important">
-
-Por ahora, no es recomendando publicar librerías con Ivy hacia NPM por que Ivy genera código que no es retrocompatible con 'View Engine', entonces las aplicaciones usando 'View Engine' no podrán consumirlas. Además, las instrucciones internas de IVY no son estables aun, lo cual puede romper potencialmente a los consumidores que usan una diferente versión de Angular a la que uso para construir la libería.
-
-Cuando una librería publicada es usada en una aplicación con Ivy, el Angular CLI automáticamente la convertirá a Ivy usando una herramienta conocida como el compilador de compatibilidad Angular (`ngcc`). Por lo tanto, publicar tus librerías usado el compilador 'View Engine' garantiza que ellas puede ser consumidas de forma transparente por ambos motores 'View Engine' y 'Ivy'.
-
-</div>
-
-{@a lib-assets}
-
-## Gestionando activos (assets) en una librería.
-
-Desde la versión 9.x de la herramienta [ng-packagr](https://github.com/ng-packagr/ng-packagr/blob/master/README.md), puedes configurar la herramienta para que automáticamente copie los activos (assets) dentro de el paquete de librería como parte del proceso de construcción.
-Puedes usar esta característica cuando tu librería necesite publicar archivos de temas opcionales, funciones de Sass o documentación (como un registro de cambios 'changelog').
-
-* Aprende como [copiar activos (assets) dentro de tu librería como parte de la construcción](https://github.com/ng-packagr/ng-packagr/blob/master/docs/copy-assets.md).
-
-* Aprende más acerca de como usar la herramienta para [incrustar activos (assets) de CSS](https://github.com/ng-packagr/ng-packagr/blob/master/docs/embed-assets-css.md).
-
-
-## Vinculando librerías
-
-Mientras trabajas en un librería publicada, puedes usar [npm link](https://docs.npmjs.com/cli/link) para evitar re instalar la librería en cada construcción.
-
-La librería debe ser reconstruida en cada cambio.
-Cuando vinculas una librería, asegurate que el paso de construir corra en modo vigía (watch mode) y que el `package.json` de la librería configure los puntos de entrada correctos.
-Por ejemplo, `main` debería apuntar a un archivo JavaScript, no a un archivo TypeScript.
-
-## Utiliza el mapeo de rutas de TypeScript por las dependencias de pares.
-
-Las librerías de Angular deben enumerar todas las dependencias `@angular/*` como dependencias de pares.
-Esto garantiza que cuando los módulos solicitan Angular, todos ellos obtienen exactamente el mismo módulo.
-Si tu librería lista `@angular/core` en `dependencies` en vez de en `peerDependencies`, podría obtener un módulo Angular diferente, lo qué haría que tu aplicación se rompiera.
-
-Cuando desarrollas una librería, tu debes instalar todas las dependencias de pares mediante `devDependencies` para garantizar que la librería compile apropiadamente.
-Una librería vinculada tendrá su propio conjunto de librerías Angular que usa para construir, ubicados en su carpeta `node_modules`.
-
-Sin embargo, esto puede causar problemas mientras construyes o corres tu aplicación.
-
-Para evitar este problema tu puedes usar el mapeo de rutas de TypeScript para indicarle a TypeScript que este debería cargar algunos módulos desde una ubicación especifica.
-
-Enumera todas las dependencias de pares que tu librería usa en el archivo de configuración `./tsconfig.json` del espacio de trabajo de TypeScript, y apúntalos a la copia local en la carpeta `node_modules` de la aplicación.
-
-```
-{
-  "compilerOptions": {
-    // ...
-    // paths are relative to `baseUrl` path.
-    "paths": {
-      "@angular/*": [
-        "./node_modules/@angular/*"
-      ]
-    }
-  }
-}
-```
-
-Este mapeador garantiza que tu librería siempre cargue las copias locales del módulo que necesita.
-
-
-## Usando tu propia librería en aplicaciones.
-
-No tienes que publicar tu librería hacia el gestor de paquetes npm para usarla en tus propias aplicaciones, pero tienes que construirla primero.
-
-Para usar tu propia librería en tu aplicación:
-
-* Construye la librería. No puedes usar una librería antes que se construya.
- <code-example language="bash">
- ng build my-lib
- </code-example>
-
-* En tus aplicaciones, importa la librería por el nombre:
- ```
- import { myExport } from 'my-lib';
- ```
-
-### Construyendo y re construyendo tu librería.
-
-El paso de construir es importante si no tienes publicada tu librería como un paquete npm y luego ha instalado el paquete de nuevo dentro tu aplicación desde npm.
-Por ejemplo, si clonas tu repositorio git y corres `npm install`, tu editor mostrará la importación de `my-lib` como perdida si no tienes aun construida tu librería.
-
-<div class="alert is-helpful">
-
-Cuando importas algo desde una librería en una aplicación Angular, Angular busca un mapeo entre el nombre de librería y una ubicación en disco.
-Cuando instalas un paquete de librería, el mapeo esta en la carpeta `node_modules`. Cuando construyes tu propia librería, tiene que encontrar el mapeo en tus rutas de `tsconfig`.
-
-Generando una librería con el Angular CLI automáticamente agrega su ruta en el archivo `tsconfig`.
-El Angular CLI usa las rutas `tsconfig` para indicarle al sistema construido donde encontrar la librería.
-
-</div>
-
-Si descubres que los cambios en tu librería no son reflejados en tu aplicación, tu aplicación probablemente esta usando una construcción antigua de la librería.
-
-Puedes re construir tu librería cada vez que hagas cambios en esta, pero este paso extra toma tiempo.
-Las *construcciones incrementales* funcionalmente mejoran la experiencia de desarrollo de librerías.
-Cada vez que un archivo es cambiando una construcción parcial es realizada y esta emite los archivos modificados.
-
-Las *Construcciones incrementales* puede ser ejecutadas como un proceso en segundo plano en tu entorno de desarrollo. Para aprovechar esta característica agrega la bandera `--watch` al comando de construcción:
-
-<code-example language="bash">
-ng build my-lib --watch
-</code-example>
-
-<div class="alert is-important">
-
-El comando `build` del CLI utiliza un constructor diferente e invoca una herramienta de construcción diferente para las librerías que para las aplicaciones.
-
-* El sistema de construcción para aplicaciones, `@angular-devkit/build-angular`, esta basado en `webpack`, y esta incluida en todos los nuevos proyectos de Angular CLI.
-* El sistema de construcción esta basado en `ng-packagr`. Este es solo agregado en tus dependencias cuando agregas una librería usando `ng generate library my-lib`.
-
-Los dos sistemas de construcción soportan diferentes cosas e incluso si ellos soportan las mismas cosas, ellos hacen esas cosas de forma diferente.
-Esto quiere decir que la fuente de TypeScript puede generar en código JavaScript diferente en una librería construida que en una aplicación construida.
-
-Por esta razón, una aplicación que depende de una librería debería solo usar el mapeo de rutas de TypeScript que apunte a la *librería construida*.
-El mapeo de rutas de TypeScript no debería apuntar hacia los archivos `.ts` fuente de la librería.

-
-Angular event binding syntax consists of a **target event** name
-within parentheses on the left of an equal sign, and a quoted
-template statement on the right.
-The following event binding listens for the button's click events, calling
-the component's `onSave()` method whenever a click occurs:
-
-<div class="lightbox">
-  <img src='generated/images/guide/template-syntax/syntax-diagram.svg' alt="Syntax diagram">
-</div>
-
-## Target event
-
-As above, the target is the button's click event.
-
-<code-example path="event-binding/src/app/app.component.html" region="event-binding-1" header="src/app/app.component.html"></code-example>
-
-Alternatively, use the `on-` prefix, known as the canonical form:
-
-<code-example path="event-binding/src/app/app.component.html" region="event-binding-2" header="src/app/app.component.html"></code-example>
-
-Element events may be the more common targets, but Angular looks first to see if the name matches an event property
-of a known directive, as it does in the following example:
-
-<code-example path="event-binding/src/app/app.component.html" region="custom-directive" header="src/app/app.component.html"></code-example>
-
-If the name fails to match an element event or an output property of a known directive,
-Angular reports an “unknown directive” error.
-
-## *$event* and event handling statements
-
-In an event binding, Angular sets up an event handler for the target event.
-
-When the event is raised, the handler executes the template statement.
-The template statement typically involves a receiver, which performs an action
-in response to the event, such as storing a value from the HTML control
-into a model.
-
-The binding conveys information about the event. This information can include data values such as an event object, string, or number named `$event`.
-
-The target event determines the shape of the `$event` object.
-If the target event is a native DOM element event, then `$event` is a
-[DOM event object](https://developer.mozilla.org/en-US/docs/Web/Events),
-with properties such as `target` and `target.value`.
-
-Consider this example:
-
-<code-example path="event-binding/src/app/app.component.html" region="event-binding-3" header="src/app/app.component.html"></code-example>
-
-This code sets the `<input>` `value` property by binding to the `name` property.
-To listen for changes to the value, the code binds to the `input`
-event of the `<input>` element.
-When the user makes changes, the `input` event is raised, and the binding executes
-the statement within a context that includes the DOM event object, `$event`.
-
-To update the `name` property, the changed text is retrieved by following the path `$event.target.value`.
-
-If the event belongs to a directive&mdash;recall that components
-are directives&mdash;`$event` has whatever shape the directive produces.
-
-## Custom events with `EventEmitter`
-
-Directives typically raise custom events with an Angular [EventEmitter](api/core/EventEmitter).
-The directive creates an `EventEmitter` and exposes it as a property.
-The directive calls `EventEmitter.emit(payload)` to fire an event, passing in a message payload, which can be anything.
-Parent directives listen for the event by binding to this property and accessing the payload through the `$event` object.
-
-Consider an `ItemDetailComponent` that presents item information and responds to user actions.
-Although the `ItemDetailComponent` has a delete button, it doesn't know how to delete the hero. It can only raise an event reporting the user's delete request.
-
-Here are the pertinent excerpts from that `ItemDetailComponent`:
-
-<code-example path="event-binding/src/app/item-detail/item-detail.component.html" header="src/app/item-detail/item-detail.component.html (template)" region="line-through"></code-example>
-
-<code-example path="event-binding/src/app/item-detail/item-detail.component.ts" header="src/app/item-detail/item-detail.component.ts (deleteRequest)" region="deleteRequest"></code-example>
-
-The component defines a `deleteRequest` property that returns an `EventEmitter`.
-When the user clicks *delete*, the component invokes the `delete()` method,
-telling the `EventEmitter` to emit an `Item` object.
-
-Now imagine a hosting parent component that binds to the `deleteRequest` event
-of the `ItemDetailComponent`.
-
-<code-example path="event-binding/src/app/app.component.html" header="src/app/app.component.html (event-binding-to-component)" region="event-binding-to-component"></code-example>
-
-When the `deleteRequest` event fires, Angular calls the parent component's
-`deleteItem()` method, passing the *item-to-delete* (emitted by `ItemDetail`)
-in the `$event` variable.
-
-## Template statements have side effects
-
-Though [template expressions](guide/interpolation#template-expressions) shouldn't have [side effects](guide/property-binding#avoid-side-effects), template
-statements usually do. The `deleteItem()` method does have
-a side effect: it deletes an item.
-
-Deleting an item updates the model, and depending on your code, triggers
-other changes including queries and saving to a remote server.
-These changes propagate through the system and ultimately display in this and other views.

-# `@Input()` and `@Output()` properties
-
-`@Input()` and `@Output()` allow Angular to share data between the parent context
-and child directives or components. An `@Input()` property is writable
-while an `@Output()` property is observable.
-
-<div class="alert is-helpful">
-
-See the <live-example></live-example> for a working example containing the code snippets in this guide.
-
-</div>
-
-Consider this example of a child/parent relationship:
-
-```html
-<parent-component>
-  <child-component></child-component>
-</parent-component>
-
-```
-
-Here, the `<child-component>` selector, or child directive, is embedded
-within a `<parent-component>`, which serves as the child's context.
-
-`@Input()` and `@Output()` act as
-the API, or application programming interface, of the child
-component in that they allow the child to
-communicate with the parent. Think of `@Input()` and `@Output()` like ports

-to flow in while `@Output()` is the doorway out of the component, allowing the

-
-<div class="alert is-helpful">

-#### `@Input()` and `@Output()` are independent
-
-Though `@Input()` and `@Output()` often appear together in apps, you can use

-

-
-## How to use `@Input()`
-
-Use the `@Input()` decorator in a child component or directive to let Angular know
-that a property in that component can receive its value from its parent component.
-It helps to remember that the data flow is from the perspective of the
-child component. So an `@Input()` allows data to be input _into_ the
-child component from the parent component.
-
-
-<div class="lightbox">
-  <img src="generated/images/guide/inputs-outputs/input.svg" alt="Input data flow diagram">
-</div>
-
-To illustrate the use of `@Input()`, edit these parts of your app:
-
-* The child component class and template
-* The parent component class and template
-
-
-### In the child
-
-To use the `@Input()` decorator in a child component class, first import
-`Input` and then decorate the property with `@Input()`:
-
-<code-example path="inputs-outputs/src/app/item-detail/item-detail.component.ts" region="use-input" header="src/app/item-detail/item-detail.component.ts"></code-example>
-
-
-In this case, `@Input()` decorates the property <code class="no-auto-link">item</code>, which has
-a type of `string`, however, `@Input()` properties can have any type, such as
-`number`, `string`, `boolean`, or `object`. The value for `item` will come from the parent component, which the next section covers.
-
-Next, in the child component template, add the following:
-
-<code-example path="inputs-outputs/src/app/item-detail/item-detail.component.html" region="property-in-template" header="src/app/item-detail/item-detail.component.html"></code-example>
-
-
-
-### In the parent
-
-The next step is to bind the property in the parent component's template.
-In this example, the parent component template is `app.component.html`.
-
-First, use the child's selector, here `<app-item-detail>`, as a directive within the
-parent component template. Then, use [property binding](guide/property-binding)
-to bind the property in the child to the property of the parent.
-
-<code-example path="inputs-outputs/src/app/app.component.html" region="input-parent" header="src/app/app.component.html"></code-example>
-
-Next, in the parent component class, `app.component.ts`, designate a value for `currentItem`:
-
-<code-example path="inputs-outputs/src/app/app.component.ts" region="parent-property" header="src/app/app.component.ts"></code-example>
-
-With `@Input()`, Angular passes the value for `currentItem` to the child so that `item` renders as `Television`.
-
-The following diagram shows this structure:
-
-<div class="lightbox">
-  <img src="generated/images/guide/inputs-outputs/input-diagram-target-source.svg" alt="Property binding diagram">
-</div>
-
-The target in the square brackets, `[]`, is the property you decorate
-with `@Input()` in the child component. The binding source, the part
-to the right of the equal sign, is the data that the parent
-component passes to the nested component.
-
-The key takeaway is that when binding to a child component's property in a parent component&mdash;that is, what's
-in square brackets&mdash;you must
-decorate the property with `@Input()` in the child component.
-
-<div class="alert is-helpful">
-
-### `OnChanges` and `@Input()`
-
-To watch for changes on an `@Input()` property, use
-`OnChanges`, one of Angular's [lifecycle hooks](guide/lifecycle-hooks#onchanges).
-`OnChanges` is specifically designed to work with properties that have the
-`@Input()` decorator. See the [`OnChanges`](guide/lifecycle-hooks#onchanges) section of the [Lifecycle Hooks](guide/lifecycle-hooks) guide for more details and examples.
-
-</div>
-
-{@a output}
-
-## How to use `@Output()`
-
-Use the `@Output()` decorator in the child component or directive to allow data to flow from
-the child _out_ to the parent.
-
-An `@Output()` property should normally be initialized to an Angular [`EventEmitter`](api/core/EventEmitter) with values flowing out of the component as [events](guide/event-binding).
-
-
-<div class="lightbox">
-  <img src="generated/images/guide/inputs-outputs/output.svg" alt="Output diagram">
-</div>
-
-Just like with `@Input()`, you can use `@Output()`
-on a property of the child component but its type should be
-`EventEmitter`.
-
-`@Output()` marks a property in a child component as a doorway
-through which data can travel from the child to the parent.
-The child component then has to raise an event so the
-parent knows something has changed. To raise an event,
-`@Output()` works hand in hand with `EventEmitter`,
-which is a class in `@angular/core` that you
-use to emit custom events.
-
-When you use `@Output()`, edit these parts of your app:
-
-* The child component class and template
-* The parent component class and template
-
-
-The following example shows how to set up an `@Output()` in a child
-component that pushes data you enter in an HTML `<input>` to an array in the
-parent component.
-
-<div class="alert is-helpful">
-
-The HTML element `<input>` and the Angular decorator `@Input()`
-are different. This documentation is about component communication in Angular as it pertains to `@Input()` and `@Output()`. For more information on the HTML element `<input>`, see the [W3C Recommendation](https://www.w3.org/TR/html5/sec-forms.html#the-input-element).
-
-</div>
-
-## In the child
-
-This example features an `<input>` where a user can enter a value and click a `<button>` that raises an event. The `EventEmitter` then relays the data to the parent component.
-
-First, be sure to import `Output` and `EventEmitter`
-in the child component class:
-
-```js
-import { Output, EventEmitter } from '@angular/core';
-
-```
-
-Next, still in the child, decorate a property with `@Output()` in the component class.
-The following example `@Output()` is called `newItemEvent` and its type is
-`EventEmitter`, which means it's an event.
-
-
-<code-example path="inputs-outputs/src/app/item-output/item-output.component.ts" region="item-output" header="src/app/item-output/item-output.component.ts"></code-example>
-
-The different parts of the above declaration are as follows:
-
-* `@Output()`&mdash;a decorator function marking the property as a way for data to go from the child to the parent
-* `newItemEvent`&mdash;the name of the `@Output()`
-* `EventEmitter<string>`&mdash;the `@Output()`'s type
-* `new EventEmitter<string>()`&mdash;tells Angular to create a new event emitter and that the data it emits is of type string. The type could be any type, such as `number`, `boolean`, and so on. For more information on `EventEmitter`, see the [EventEmitter API documentation](api/core/EventEmitter).
-
-Next, create an `addNewItem()` method in the same component class:
-
-<code-example path="inputs-outputs/src/app/item-output/item-output.component.ts" region="item-output-class" header="src/app/item-output/item-output.component.ts"></code-example>
-
-The `addNewItem()` function uses the `@Output()`, `newItemEvent`,
-to raise an event in which it emits the value the user
-types into the `<input>`. In other words, when
-the user clicks the add button in the UI, the child lets the parent know
-about the event and gives that data to the parent.
-
-### In the child's template
-
-The child's template has two controls. The first is an HTML `<input>` with a
-[template reference variable](guide/template-reference-variables) , `#newItem`,
-where the user types in an item name. Whatever the user types
-into the `<input>` gets stored in the `#newItem` variable.
-
-<code-example path="inputs-outputs/src/app/item-output/item-output.component.html" region="child-output" header="src/app/item-output/item-output.component.html"></code-example>
-
-The second element is a `<button>`
-with an [event binding](guide/event-binding). You know it's
-an event binding because the part to the left of the equal
-sign is in parentheses, `(click)`.
-
-The `(click)` event is bound to the `addNewItem()` method in the child component class which
-takes as its argument whatever the value of `#newItem` is.
-
-Now the child component has an `@Output()`
-for sending data to the parent and a method for raising an event.
-The next step is in the parent.
-
-## In the parent
-
-In this example, the parent component is `AppComponent`, but you could use
-any component in which you could nest the child.
-
-The `AppComponent` in this example features a list of `items`
-in an array and a method for adding more items to the array.
-
-<code-example path="inputs-outputs/src/app/app.component.ts" region="add-new-item" header="src/app/app.component.ts"></code-example>
-
-The `addItem()` method takes an argument in the form of a string
-and then pushes, or adds, that string to the `items` array.
-
-### In the parent's template
-
-Next, in the parent's template, bind the parent's
-method to the child's event. Put the child selector, here `<app-item-output>`,
-within the parent component's
-template, `app.component.html`.
-
-<code-example path="inputs-outputs/src/app/app.component.html" region="output-parent" header="src/app/app.component.html"></code-example>
-
-The event binding, `(newItemEvent)='addItem($event)'`, tells
-Angular to connect the event in the child, `newItemEvent`, to
-the method in the parent, `addItem()`, and that the event that the child
-is notifying the parent about is to be the argument of `addItem()`.
-In other words, this is where the actual hand off of data takes place.
-The `$event` contains the data that the user types into the `<input>`
-in the child template UI.
-
-Now, in order to see the `@Output()` working, add the following to the parent's template:
-
-```html
-  <ul>
-    <li *ngFor="let item of items">{{item}}</li>
-  </ul>
-  ```
-
-The `*ngFor` iterates over the items in the `items` array. When you enter a value in the child's `<input>` and click the button, the child emits the event and the parent's `addItem()` method pushes the value to the `items` array and it renders in the list.
-
-
-## `@Input()` and `@Output()` together
-
-You can use `@Input()` and `@Output()` on the same child component as in the following:
-
-<code-example path="inputs-outputs/src/app/app.component.html" region="together" header="src/app/app.component.html"></code-example>
-
-The target, `item`, which is an `@Input()` property in the child component class, receives its value from the parent's property, `currentItem`. When you click delete, the child component raises an event, `deleteRequest`, which is the argument for the parent's `crossOffItem()` method.
-
-The following diagram is of an `@Input()` and an `@Output()` on the same
-child component and shows the different parts of each:
-
-<div class="lightbox">
-  <img src="generated/images/guide/inputs-outputs/input-output-diagram.svg" alt="Input/Output diagram">
-</div>
-
-As the diagram shows, use inputs and outputs together in the same manner as using them separately. Here, the child selector is `<app-input-output>` with `item` and `deleteRequest` being `@Input()` and `@Output()`
-properties in the child component class. The property `currentItem` and the method `crossOffItem()` are both in the parent component class.
-
-To combine property and event bindings using the banana-in-a-box
-syntax, `[()]`, see [Two-way Binding](guide/two-way-binding).
-
-## `@Input()` and `@Output()` declarations
-
-Instead of using the `@Input()` and `@Output()` decorators
-to declare inputs and outputs, you can identify
-members in the `inputs` and `outputs` arrays
-of the directive metadata, as in this example:
-
-<code-example path="inputs-outputs/src/app/in-the-metadata/in-the-metadata.component.ts" region="metadata" header="src/app/in-the-metadata/in-the-metadata.component.ts"></code-example>
-
-While declaring `inputs` and `outputs` in the `@Directive` and `@Component`
-metadata is possible, it is a better practice to use the `@Input()` and `@Output()`
-class decorators instead, as follows:
-
-<code-example path="inputs-outputs/src/app/input-output/input-output.component.ts" region="input-output" header="src/app/input-output/input-output.component.ts"></code-example>
-
-See the [Decorate input and output properties](guide/styleguide#decorate-input-and-output-properties) section of the
-[Style Guide](guide/styleguide) for details.
-
-
-
-<div class="alert is-helpful">
-
-If you get a template parse error when trying to use inputs or outputs, but you know that the
-properties do indeed exist, double check
-that your properties are annotated with `@Input()` / `@Output()` or that you've declared
-them in an `inputs`/`outputs` array:
-
-<code-example language="bash">
-Uncaught Error: Template parse errors:
-Can't bind to 'item' since it isn't a known property of 'app-item-detail'
-</code-example>
-
-</div>
-
-{@a aliasing-io}
-
-## Aliasing inputs and outputs
-
-Sometimes the public name of an input/output property should be different from the internal name. While it is a best practice to avoid this situation, Angular does
-offer a solution.
-
-### Aliasing in the metadata
-
-Alias inputs and outputs in the metadata using a colon-delimited (`:`) string with
-the directive property name on the left and the public alias on the right:
-
-<code-example path="inputs-outputs/src/app/aliasing/aliasing.component.ts" region="alias" header="src/app/aliasing/aliasing.component.ts"></code-example>
-
-
-### Aliasing with the `@Input()`/`@Output()` decorator
-
-You can specify the alias for the property name by passing the alias name to the `@Input()`/`@Output()` decorator. The internal name remains as usual.

-# Interpolation and template expressions
-
-Interpolation allows you to incorporate calculated strings into the text
-between HTML element tags and within attribute assignments. Template
-expressions are what you use to calculate those strings.
-
-<div class="alert is-helpful">
-
-See the <live-example></live-example> for all of
-the syntax and code snippets in this guide.
-
-</div>
-
-## Interpolation `{{...}}`
-
-Interpolation refers to embedding expressions into marked up text.
-By default, interpolation uses as its delimiter the double curly braces, `{{` and `}}`.
-
-In the following snippet, `{{ currentCustomer }}` is an example of interpolation.
-
-<code-example path="interpolation/src/app/app.component.html" region="interpolation-example1" header="src/app/app.component.html"></code-example>
-
-The text between the braces is often the name of a component
-property. Angular replaces that name with the
-string value of the corresponding component property.
-
-<code-example path="interpolation/src/app/app.component.html" region="component-property" header="src/app/app.component.html"></code-example>
-
-In the example above, Angular evaluates the `title` and `itemImageUrl` properties
-and fills in the blanks, first displaying some title text and then an image.
-
-More generally, the text between the braces is a **template expression**
-that Angular first **evaluates** and then **converts to a string**.
-The following interpolation illustrates the point by adding two numbers:
-
-<code-example path="interpolation/src/app/app.component.html" region="convert-string" header="src/app/app.component.html"></code-example>
-
-The expression can invoke methods of the host component such as `getVal()` in
-the following example:
-
-<code-example path="interpolation/src/app/app.component.html" region="invoke-method" header="src/app/app.component.html"></code-example>
-
-Angular evaluates all expressions in double curly braces,
-converts the expression results to strings, and links them with neighboring literal strings. Finally,
-it assigns this composite interpolated result to an **element or directive property**.
-
-You appear to be inserting the result between element tags and assigning it to attributes.
-However, interpolation is a special syntax that Angular converts into a *property binding*.
-
-<div class="alert is-helpful">
-
-If you'd like to use something other than `{{` and `}}`, you can
-configure the interpolation delimiter via the
-[interpolation](api/core/Component#interpolation)
-option in the `Component` metadata.
-
-</div>
-
-## Template expressions
-
-A template **expression** produces a value and appears within the double
-curly braces, `{{ }}`.
-Angular executes the expression and assigns it to a property of a binding target;
-the target could be an HTML element, a component, or a directive.
-
-The interpolation braces in `{{1 + 1}}` surround the template expression `1 + 1`.
-In the property binding,
-a template expression appears in quotes to the right of the&nbsp;`=` symbol as in `[property]="expression"`.
-
-In terms of syntax, template expressions are similar to JavaScript.
-Many JavaScript expressions are legal template expressions, with a few exceptions.
-
-You can't use JavaScript expressions that have or promote side effects,
-including:
-
-* Assignments (`=`, `+=`, `-=`, `...`)
-* Operators such as `new`, `typeof`, `instanceof`, etc.
-* Chaining expressions with <code>;</code> or <code>,</code>
-* The increment and decrement operators `++` and `--`
-* Some of the ES2015+ operators
-
-Other notable differences from JavaScript syntax include:
-
-* No support for the bitwise operators such as `|` and `&`
-* New [template expression operators](guide/template-expression-operators), such as `|`, `?.` and `!`
-
-
-## Expression context
-
-The *expression context* is typically the _component_ instance.
-In the following snippets, the `recommended` within double curly braces and the

-An expression may also refer to properties of the _template's_ context
-such as a template input variable,
-<!-- link to built-in-directives#template-input-variables -->
-`let customer`, or a template reference variable, `#customerInput`.

-
-The context for terms in an expression is a blend of the _template variables_,
-the directive's _context_ object (if it has one), and the component's _members_.
-If you reference a name that belongs to more than one of these namespaces,
-the template variable name takes precedence, followed by a name in the directive's _context_,
-and, lastly, the component's member names.
-
-The previous example presents such a name collision. The component has a `customer`
-property and the `*ngFor` defines a `customer` template variable.
-
-<div class="alert is-helpful">
-
-The `customer` in `{{customer.name}}`
-refers to the template input variable, not the component's property.
-
-Template expressions cannot refer to anything in
-the global namespace, except `undefined`. They can't refer to
-`window` or `document`. Additionally, they
-can't call `console.log()` or `Math.max()` and they are restricted to referencing
-members of the expression context.

-
-## Expression guidelines
-
-When using template expressions follow these guidelines:
-
-* [Simplicity](guide/interpolation#simplicity)
-* [Quick execution](guide/interpolation#quick-execution)
-* [No visible side effects](guide/interpolation#no-visible-side-effects)
-
-### Simplicity
-
-Although it's possible to write complex template expressions, it's a better
-practice to avoid them.
-
-A property name or method call should be the norm, but an occasional Boolean negation, `!`, is OK.
-Otherwise, confine application and business logic to the component,
-where it is easier to develop and test.
-
-### Quick execution
-
-Angular executes template expressions after every change detection cycle.
-Change detection cycles are triggered by many asynchronous activities such as
-promise resolutions, HTTP results, timer events, key presses and mouse moves.
-
-Expressions should finish quickly or the user experience may drag, especially on slower devices.
-Consider caching values when their computation is expensive.
-
-### No visible side effects
-
-A template expression should not change any application state other than the value of the
-target property.
-
-This rule is essential to Angular's "unidirectional data flow" policy.
-You should never worry that reading a component value might change some other displayed value.
-The view should be stable throughout a single rendering pass.
-
-An [idempotent](https://en.wikipedia.org/wiki/Idempotence) expression is ideal because
-it is free of side effects and improves Angular's change detection performance.
-In Angular terms, an idempotent expression always returns
-*exactly the same thing* until one of its dependent values changes.
-
-Dependent values should not change during a single turn of the event loop.
-If an idempotent expression returns a string or a number, it returns the same string or number when called twice in a row. If the expression returns an object, including an `array`, it returns the same object *reference* when called twice in a row.
-
-<div class="alert is-helpful">
-
-There is one exception to this behavior that applies to `*ngFor`. `*ngFor` has `trackBy` functionality that can deal with referential inequality of objects when iterating over them. See [*ngFor with `trackBy`](guide/built-in-directives #ngfor-with-trackby) for details.

-# Optimizing client app size with lightweight injection tokens
-
-This page provides a conceptual overview of a dependency injection technique that is recommended for library developers.
-Designing your library with *lightweight injection tokens* helps optimize the bundle size of client applications that use your library.
-
-You can manage the dependency structure among your components and injectable services to optimize bundle size by using [tree-shakable providers](guide/dependency-injection-providers#tree-shakable-providers).
-This normally ensures that if a provided component or service is never actually used by the app, the compiler can eliminate its code from the bundle.
-
-However, due to the way Angular stores injection tokens, it is possible that such an unused component or service can end up in the bundle anyway.
-This page describes a dependency-injection design pattern that supports proper tree-shaking by using lightweight injection tokens.
-
-The lightweight injection token design pattern is especially important for library developers. It ensures that when an application uses only some of your library's capabilities, the unused code can be eliminated from the client's app bundle.
-
-When an application uses your library, there might be some services that your library supplies which the client app doesn't use.
-In this case, the app developer should expect that service to be tree-shaken, and not contribute to the size of the compiled app.
-Because the application developer cannot know about or remedy a tree-shaking problem in the library, it is the responsibility of the library developer to do so.
-To prevent the retention of unused components, your library should use the lightweight injection token design pattern.
-
-## When tokens are retained
-
-To better explain the condition under which token retention occurs, consider a library that provides a library-card component, which contains a body and can contain an optional header.
-
-```
-<lib-card>
-  <lib-header>...</lib-header>
-</lib-card>
-```
-
-In a likely implementation, the `<lib-card>` component uses `@ContentChild()` or `@ContentChildren()` to obtain `<lib-header>` and `<lib-body>`, as in the following.
-
-```
-@Component({
-  selector: 'lib-header',
-  ...,
-})
-class LibHeaderComponent {}
-
-@Component({
-  selector: 'lib-card',
-  ...,
-})
-class LibCardComponent {
-  @ContentChild(LibHeaderComponent)
-  header: LibHeaderComponent|null = null;
-}
-```
-
-Because `<lib-header>` is optional, the element can appear in the template in its minimal form,
-`<lib-card></lib-card>`.
-In this case, `<lib-header>` is not used and you would expect it to be tree-shaken, but that is not what happens.
-This is because `LibCardComponent` actually contains two references to the `LibHeaderComponent`.
-
-`@ContentChild(LibHeaderComponent) header: LibHeaderComponent;`
-
-* One of these reference is in the *type position*-- that is, it specifies `LibHeaderComponent` as a type: `header: LibHeaderComponent;`.
-
-* The other reference is in the *value position*-- that is, LibHeaderComponent is the value of the `@ContentChild()` parameter decorator: `@ContentChild(LibHeaderComponent)`.
-
-The compiler handles token references in these positions differently.
-
-* The compiler erases *type position* references after conversion from TypeScript, so they have no impact on tree-shaking.
-
-* The compiler must retain *value position*  references at runtime, which prevents the component from being tree-shaken.
-
-In the example, the compiler retains the `LibHeaderComponent` token that occurs in the value position, which prevents the referenced component from being tree-shaken, even if the application developer does not actually use `<lib-header>` anywhere.
-If `LibHeaderComponent` is large (code, template, and styles), including it unnecessarily can significantly increase the size of the client application.
-
-## When to use the lightweight injection token pattern
-
-The tree-shaking problem arises when a component is used as an injection token.
-There are two cases when that can happen.
-
-* The token is used in the value position of a [content query](guide/lifecycle-hooks#using-aftercontent-hooks "See more about using content queries.").
-* The token is used as a type specifier for constructor injection.
-
-In the following example, both uses of the `OtherComponent` token cause retention of `OtherComponent` (that is, prevent it from being tree-shaken when it is not used).
-
-```
-class MyComponent {
-  constructor(@Optional() other: OtherComponent) {}
-
-  @ContentChild(OtherComponent)
-  other: OtherComponent|null;
-}
-```
-
-Although tokens used only as type specifiers are removed when converted to JavaScript, all tokens used for dependency injection are needed at runtime.
-These effectively change `constructor(@Optional() other: OtherComponent)` to `constructor(@Optional() @Inject(OtherComponent) other)`. The token is now in a value position, and causes the tree shaker to retain the reference.
-
-<div class="alert is helpful">
-
-For all services, a library should use [tree-shakable providers](guide/dependency-injection-providers#tree-shakable-providers), providing dependencies at the root level rather than in component constructors.
-
-</div>
-
-## Using lightweight injection tokens
-
-The lightweight injection token design pattern consists of using a small abstract class as an injection token, and providing the actual implementation at a later stage.
-The abstract class is retained (not tree-shaken), but it is small and has no material impact on the application size.
-
-The following example shows how this works for the `LibHeaderComponent`.
-
-```
-abstract class LibHeaderToken {}
-
-@Component({
-  selector: 'lib-header',
-  providers: [
-    {provide: LibHeaderToken, useExisting: LibHeaderComponent}
-  ]
-  ...,
-})
-class LibHeaderComponent extends LibHeaderToken {}
-
-@Component({
-  selector: 'lib-card',
-  ...,
-})
-class LibCardComponent {
-  @ContentChild(LibHeaderToken) header: LibHeaderToken|null = null;
-}
-```
-
-In this example, the `LibCardComponent` implementation no longer refers to `LibHeaderComponent` in either the type position or the value position.
-This allows full tree shaking of `LibHeaderComponent` to take place.
-The `LibHeaderToken` is retained, but it is only a class declaration, with no concrete implementation. It is small and does not materially impact the application size when retained after compilation.
-
-Instead, `LibHeaderComponent` itself implements the abstract `LibHeaderToken` class. You can safely use that token as the provider in the component definition, allowing Angular to correctly inject the concrete type.
-
-To summarize, the lightweight injection token pattern consists of the following.
-
-1. A lightweight injection token that is represented as an abstract class.
-2. A component definition that implements the abstract class.
-3. Injection of the lightweight pattern, using ` @ContentChild()` or `@ContentChildren()`.
-4. A provider in the implementation of the lightweight injection token which associates the lightweight injection token with the implementation.
-
-### Use the lightweight injection token for API definition
-
-A component that injects a lightweight injection token might need to invoke a method in the injected class.
-Because the token is now an abstract class, and the injectable component implements that class, you must also declare an abstract method in the abstract lightweight injection token class.
-The implementation of the method (with all of its code overhead) resides in the injectable component that can be tree-shaken.
-This allows the parent to communicate with the child (if it is present) in a type-safe manner.
-
-For example, the `LibCardComponent` now queries`LibHeaderToken` rather than `LibHeaderComponent`.
-The following example shows how the pattern allows `LibCardComponent` to communicate with the `LibHeaderComponent` without actually referring to `LibHeaderComponent`.
-
-```
-abstract class LibHeaderToken {
-  abstract doSomething(): void;
-}
-
-@Component({
-  selector: 'lib-header',
-  providers: [
-    {provide: LibHeaderToken, useExisting: LibHeader}
-  ]
-  ...,
-})
-class LibHeaderComponent extends LibHeaderToken {
-  doSomething(): void {
-    // Concrete implementation of `doSomething`
-  }
-}
-
-@Component({
-  selector: 'lib-card',
-  ...,
-})
-class LibCardComponent implement AfterContentInit {
-  @ContentChild(LibHeaderToken)
-  header: LibHeaderToken|null = null;
-
-  ngAfterContentInit(): void {
-    this.header && this.header.doSomething();
-  }
-}
-```
-
-In this example the parent  queries the token to obtain the child component, and stores the resulting component reference if it is present.
-Before calling a method in the child, the parent component checks to see if the child component is present.
-If the child component has been tree-shaken, there is no runtime reference to it, and no call to its method.
-
-### Naming your lightweight injection token
-
-Lightweight injection tokens are only useful with components. The Angular style guide suggests that you name components using the "Component" suffix. The example "LibHeaderComponent" follows this convention.
-
-To maintain the relationship between the component and its token while still distinguishing between them, the recommended style is to use the component base name with the suffix "Token" to name your lightweight injection tokens: "LibHeaderToken".

-# Property binding `[property]`
-
-Use property binding to _set_ properties of target elements or
-directive `@Input()` decorators.
-
-<div class="alert is-helpful">
-
-See the <live-example></live-example> for a working example containing the code snippets in this guide.
-
-</div>
-
-## One-way in
-
-Property binding flows a value in one direction,
-from a component's property into a target element property.
-
-You can't use property
-binding to read or pull values out of target elements. Similarly, you cannot use
-property binding to call a method on the target element.
-If the element raises events, you can listen to them with an [event binding](guide/event-binding).
-
-If you must read a target element property or call one of its methods,
-see the API reference for [ViewChild](api/core/ViewChild) and
-[ContentChild](api/core/ContentChild).
-
-## Examples
-
-The most common property binding sets an element property to a component
-property value. An example is
-binding the `src` property of an image element to a component's `itemImageUrl` property:
-
-<code-example path="property-binding/src/app/app.component.html" region="property-binding" header="src/app/app.component.html"></code-example>
-
-Here's an example of binding to the `colSpan` property. Notice that it's not `colspan`,
-which is the attribute, spelled with a lowercase `s`.
-
-<code-example path="property-binding/src/app/app.component.html" region="colSpan" header="src/app/app.component.html"></code-example>
-
-For more details, see the [MDN HTMLTableCellElement](https://developer.mozilla.org/en-US/docs/Web/API/HTMLTableCellElement) documentation.
-
-For more information about `colSpan` and `colspan`, see the [Attribute binding](guide/attribute-binding#colspan) guide.
-
-Another example is disabling a button when the component says that it `isUnchanged`:
-
-<code-example path="property-binding/src/app/app.component.html" region="disabled-button" header="src/app/app.component.html"></code-example>
-
-Another is setting a property of a directive:
-
-<code-example path="property-binding/src/app/app.component.html" region="class-binding" header="src/app/app.component.html"></code-example>
-
-Yet another is setting the model property of a custom component&mdash;a great way
-for parent and child components to communicate:
-
-<code-example path="property-binding/src/app/app.component.html" region="model-property-binding" header="src/app/app.component.html"></code-example>
-
-## Binding targets
-
-An element property between enclosing square brackets identifies the target property.
-The target property in the following code is the image element's `src` property.
-
-<code-example path="property-binding/src/app/app.component.html" region="property-binding" header="src/app/app.component.html"></code-example>
-
-There's also the `bind-` prefix alternative:
-
-<code-example path="property-binding/src/app/app.component.html" region="bind-prefix" header="src/app/app.component.html"></code-example>
-
-
-In most cases, the target name is the name of a property, even
-when it appears to be the name of an attribute.
-So in this case, `src` is the name of the `<img>` element property.
-
-Element properties may be the more common targets,
-but Angular looks first to see if the name is a property of a known directive,
-as it is in the following example:
-
-<code-example path="property-binding/src/app/app.component.html" region="class-binding" header="src/app/app.component.html"></code-example>
-
-Technically, Angular is matching the name to a directive `@Input()`,
-one of the property names listed in the directive's `inputs` array
-or a property decorated with `@Input()`.
-Such inputs map to the directive's own properties.
-
-If the name fails to match a property of a known directive or element, Angular reports an “unknown directive” error.
-
-<div class="alert is-helpful">
-
-Though the target name is usually the name of a property,
-there is an automatic attribute-to-property mapping in Angular for
-several common attributes. These include `class`/`className`, `innerHtml`/`innerHTML`, and
-`tabindex`/`tabIndex`.
-
-</div>
-
-
-## Avoid side effects
-
-Evaluation of a template expression should have no visible side effects.
-The expression language itself, or the way you write template expressions,
-helps to a certain extent;
-you can't assign a value to anything in a property binding expression
-nor use the increment and decrement operators.
-
-For example, you could have an expression that invoked a property or method that had
-side effects. The expression could call something like `getFoo()` where only you
-know what `getFoo()` does. If `getFoo()` changes something
-and you happen to be binding to that something,
-Angular may or may not display the changed value. Angular may detect the
-change and throw a warning error.
-As a best practice, stick to properties and to methods that return
-values and avoid side effects.
-
-## Return the proper type
-
-The template expression should evaluate to the type of value
-that the target property expects.
-Return a string if the target property expects a string, a number if it
-expects a number, an object if it expects an object, and so on.
-
-In the following example, the `childItem` property of the `ItemDetailComponent` expects a string, which is exactly what you're sending in the property binding:
-
-<code-example path="property-binding/src/app/app.component.html" region="model-property-binding" header="src/app/app.component.html"></code-example>
-
-You can confirm this by looking in the `ItemDetailComponent` where the `@Input` type is set to a string:
-<code-example path="property-binding/src/app/item-detail/item-detail.component.ts" region="input-type" header="src/app/item-detail/item-detail.component.ts (setting the @Input() type)"></code-example>
-
-As you can see here, the `parentItem` in `AppComponent` is a string, which the `ItemDetailComponent` expects:
-<code-example path="property-binding/src/app/app.component.ts" region="parent-data-type" header="src/app/app.component.ts"></code-example>
-
-### Passing in an object
-
-The previous simple example showed passing in a string. To pass in an object,
-the syntax and thinking are the same.
-
-In this scenario, `ItemListComponent` is nested within `AppComponent` and the `items` property expects an array of objects.
-
-<code-example path="property-binding/src/app/app.component.html" region="pass-object" header="src/app/app.component.html"></code-example>
-
-The `items` property is declared in the `ItemListComponent` with a type of `Item` and decorated with `@Input()`:
-
-<code-example path="property-binding/src/app/item-list/item-list.component.ts" region="item-input" header="src/app/item-list.component.ts"></code-example>
-
-In this sample app, an `Item` is an object that has two properties; an `id` and a `name`.
-
-<code-example path="property-binding/src/app/item.ts" region="item-class" header="src/app/item.ts"></code-example>
-
-While a list of items exists in another file, `mock-items.ts`, you can
-specify a different item in `app.component.ts` so that the new item will render:
-
-<code-example path="property-binding/src/app/app.component.ts" region="pass-object" header="src/app.component.ts"></code-example>
-
-You just have to make sure, in this case, that you're supplying an array of objects because that's the type of `Item` and is what the nested component, `ItemListComponent`, expects.
-
-In this example, `AppComponent` specifies a different `item` object
-(`currentItems`) and passes it to the nested `ItemListComponent`. `ItemListComponent` was able to use `currentItems` because it matches what an `Item` object is according to `item.ts`. The `item.ts` file is where
-`ItemListComponent` gets its definition of an `item`.
-
-## Remember the brackets
-
-The brackets, `[]`, tell Angular to evaluate the template expression.
-If you omit the brackets, Angular treats the string as a constant
-and *initializes the target property* with that string:
-
-<code-example path="property-binding/src/app/app.component.html" region="no-evaluation" header="src/app.component.html"></code-example>
-
-
-Omitting the brackets will render the string
-`parentItem`, not the value of `parentItem`.
-
-## One-time string initialization
-
-You *should* omit the brackets when all of the following are true:
-
-* The target property accepts a string value.
-* The string is a fixed value that you can put directly into the template.
-* This initial value never changes.
-
-You routinely initialize attributes this way in standard HTML, and it works
-just as well for directive and component property initialization.
-The following example initializes the `prefix` property of the `StringInitComponent` to a fixed string,
-not a template expression. Angular sets it and forgets about it.
-
-<code-example path="property-binding/src/app/app.component.html" region="string-init" header="src/app/app.component.html"></code-example>
-
-The `[item]` binding, on the other hand, remains a live binding to the component's `currentItems` property.
-
-## Property binding vs. interpolation
-
-You often have a choice between interpolation and property binding.
-The following binding pairs do the same thing:
-
-<code-example path="property-binding/src/app/app.component.html" region="property-binding-interpolation" header="src/app/app.component.html"></code-example>
-
-Interpolation is a convenient alternative to property binding in
-many cases. When rendering data values as strings, there is no
-technical reason to prefer one form to the other, though readability
-tends to favor interpolation. However, *when setting an element
-property to a non-string data value, you must use property binding*.
-
-## Content security
-
-Imagine the following malicious content.
-
-<code-example path="property-binding/src/app/app.component.ts" region="malicious-content" header="src/app/app.component.ts"></code-example>
-
-In the component template, the content might be used with interpolation:
-
-<code-example path="property-binding/src/app/app.component.html" region="malicious-interpolated" header="src/app/app.component.html"></code-example>
-
-Fortunately, Angular data binding is on alert for dangerous HTML. In the above case,
-the HTML displays as is, and the Javascript does not execute. Angular **does not**
-allow HTML with script tags to leak into the browser, neither with interpolation
-nor property binding.
-
-In the following example, however, Angular [sanitizes](guide/security#sanitization-and-security-contexts)
-the values before displaying them.
-
-<code-example path="property-binding/src/app/app.component.html" region="malicious-content" header="src/app/app.component.html"></code-example>
-
-Interpolation handles the `<script>` tags differently than
-property binding but both approaches render the
-content harmlessly. The following is the browser output
-of the `evilTitle` examples.
-
-<code-example language="bash">
-"Template <script>alert("evil never sleeps")</script> Syntax" is the interpolated evil title.
-"Template alert("evil never sleeps")Syntax" is the property bound evil title.
-</code-example>

-## The pipe operator (`|`)
-
-The result of an expression might require some transformation before you're ready to use it in a binding.
-For example, you might display a number as a currency, change text to uppercase, or filter a list and sort it.
-
-Pipes are simple functions that accept an input value and return a transformed value.
-They're easy to apply within template expressions, using the pipe operator (`|`):
-
-<code-example path="template-expression-operators/src/app/app.component.html" region="uppercase-pipe" header="src/app/app.component.html"></code-example>
-
-The pipe operator passes the result of an expression on the left to a pipe function on the right.
-
-You can chain expressions through multiple pipes:
-
-<code-example path="template-expression-operators/src/app/app.component.html" region="pipe-chain" header="src/app/app.component.html"></code-example>
-
-And you can also [apply parameters](guide/pipes#parameterizing-a-pipe) to a pipe:
-
-<code-example path="template-expression-operators/src/app/app.component.html" region="date-pipe" header="src/app/app.component.html"></code-example>
-
-The `json` pipe is particularly helpful for debugging bindings:
-
-<code-example path="template-expression-operators/src/app/app.component.html" region="json-pipe" header="src/app/app.component.html"></code-example>
-
-The generated output would look something like this:

-{@a safe-navigation-operator}
-
-## The safe navigation operator ( `?` ) and null property paths
-
-The Angular safe navigation operator, `?`, guards against `null` and `undefined`
-values in property paths. Here, it protects against a view render failure if `item` is `null`.
-
-<code-example path="template-expression-operators/src/app/app.component.html" region="safe" header="src/app/app.component.html"></code-example>
-
-If `item` is `null`, the view still renders but the displayed value is blank; you see only "The item name is:" with nothing after it.
-
-Consider the next example, with a `nullItem`.
-
-<code-example language="html">
-  The null item name is {{nullItem.name}}
-</code-example>
-
-Since there is no safe navigation operator and `nullItem` is `null`, JavaScript and Angular would throw a `null` reference error and break the rendering process of Angular:
-
-<code-example language="bash">
-  TypeError: Cannot read property 'name' of null.
-</code-example>
-
-Sometimes however, `null` values in the property
-path may be OK under certain circumstances,
-especially when the value starts out null but the data arrives eventually.
-
-With the safe navigation operator, `?`, Angular stops evaluating the expression when it hits the first `null` value and renders the view without errors.
-
-It works perfectly with long property paths such as `a?.b?.c?.d`.
-
-
-<hr/>
-
-{@a non-null-assertion-operator}
-
-## The non-null assertion operator ( `!` )
-
-As of Typescript 2.0, you can enforce [strict null checking](http://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-0.html "Strict null checking in TypeScript") with the `--strictNullChecks` flag. TypeScript then ensures that no variable is unintentionally `null` or `undefined`.
-
-In this mode, typed variables disallow `null` and `undefined` by default. The type checker throws an error if you leave a variable unassigned or try to assign `null` or `undefined` to a variable whose type disallows `null` and `undefined`.
-
-The type checker also throws an error if it can't determine whether a variable will be `null` or `undefined` at runtime. You tell the type checker not to throw an error by applying the postfix
-[non-null assertion operator, !](http://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-0.html#non-null-assertion-operator "Non-null assertion operator").
-
-The Angular non-null assertion operator, `!`, serves the same purpose in
-an Angular template. For example, you can assert that `item` properties are also defined.
-
-<code-example path="template-expression-operators/src/app/app.component.html" region="non-null" header="src/app/app.component.html"></code-example>
-
-When the Angular compiler turns your template into TypeScript code,
-it prevents TypeScript from reporting that `item.color` might be `null` or `undefined`.
-
-Unlike the [_safe navigation operator_](guide/template-expression-operators#safe-navigation-operator "Safe navigation operator (?)"),
-the non-null assertion operator does not guard against `null` or `undefined`.
-Rather, it tells the TypeScript type checker to suspend strict `null` checks for a specific property expression.
-
-The non-null assertion operator, `!`, is optional with the exception that you must use it when you turn on strict null checks.
-
-{@a any-type-cast-function}
-
-## The `$any()` type cast function
-
-Sometimes a binding expression triggers a type error during [AOT compilation](guide/aot-compiler) and it is not possible or difficult to fully specify the type.
-To silence the error, you can use the `$any()` cast function to cast
-the expression to the [`any` type](http://www.typescriptlang.org/docs/handbook/basic-types.html#any) as in the following example:
-
-<code-example path="built-in-template-functions/src/app/app.component.html" region="any-type-cast-function-1" header="src/app/app.component.html"></code-example>
-
-When the Angular compiler turns this template into TypeScript code,
-it prevents TypeScript from reporting that `bestByDate` is not a member of the `item`
-object when it runs type checking on the template.
-
-The `$any()` cast function also works with `this` to allow access to undeclared members of
-the component.
-
-<code-example path="built-in-template-functions/src/app/app.component.html" region="any-type-cast-function-2" header="src/app/app.component.html"></code-example>

-# Template reference variables (`#var`)
-
-A **template reference variable** is often a reference to a DOM element within a template.
-It can also refer to a directive (which contains a component), an element, [TemplateRef](api/core/TemplateRef), or a <a href="https://developer.mozilla.org/en-US/docs/Web/Web_Components" title="MDN: Web Components">web component</a>.

-Use the hash symbol (#) to declare a reference variable.
-The following reference variable, `#phone`, declares a `phone` variable on an `<input>` element.

-
-You can refer to a template reference variable anywhere in the component's template.
-Here, a `<button>` further down the template refers to the `phone` variable.
-
-<code-example path="template-reference-variables/src/app/app.component.html" region="ref-phone" header="src/app/app.component.html"></code-example>
-
-<h3 class="no-toc">How a reference variable gets its value</h3>
-
-In most cases, Angular sets the reference variable's value to the element on which it is declared.
-In the previous example, `phone` refers to the phone number `<input>`.
-The button's click handler passes the `<input>` value to the component's `callPhone()` method.
-
-The `NgForm` directive can change that behavior and set the value to something else. In the following example, the template reference variable, `itemForm`, appears three times separated
-by HTML.
-
-<code-example path="template-reference-variables/src/app/app.component.html" region="ngForm" header="src/app/hero-form.component.html"></code-example>
-
-The reference value of itemForm, without the ngForm attribute value, would be
-the [HTMLFormElement](https://developer.mozilla.org/en-US/docs/Web/API/HTMLFormElement).
-There is, however, a difference between a Component and a Directive in that a `Component`
-will be referenced without specifying the attribute value, and a `Directive` will not
-change the implicit reference (that is, the element).
-
-
-
-However, with `NgForm`, `itemForm` is a reference to the [NgForm](api/forms/NgForm "API: NgForm")
-directive with the ability to track the value and validity of every control in the form.
-
-The native `<form>` element doesn't have a `form` property, but the `NgForm` directive does, which allows disabling the submit button
-if the `itemForm.form.valid` is invalid and passing the entire form control tree
-to the parent component's `onSubmit()` method.
-
-<h3 class="no-toc">Template reference variable considerations</h3>
-
-A template _reference_ variable (`#phone`) is not the same as a template _input_ variable (`let phone`) such as in an [`*ngFor`](guide/built-in-directives#template-input-variable).
-See [_Structural directives_](guide/structural-directives#template-input-variable) for more information.
-
-The scope of a reference variable is the entire template. So, don't define the same variable name more than once in the same template as the runtime value will be unpredictable.

-
-You can use the `ref-` prefix alternative to `#`.

-# Template statements
-
-A template **statement** responds to an **event** raised by a binding target
-such as an element, component, or directive.
-
-<div class="alert is-helpful">
-
-See the <live-example name="template-syntax">Template syntax</live-example> for
-the syntax and code snippets in this guide.

-
-A template statement *has a side effect*.
-That's the whole point of an event.
-It's how you update application state from user action.
-
-Responding to events is the other side of Angular's "unidirectional data flow".
-You're free to change anything, anywhere, during this turn of the event loop.
-
-Like template expressions, template *statements* use a language that looks like JavaScript.
-The template statement parser differs from the template expression parser and
-specifically supports both basic assignment (`=`) and chaining expressions with <code>;</code>.
-
-However, certain JavaScript and template expression syntax is not allowed:
-
-* <code>new</code>
-* increment and decrement operators, `++` and `--`
-* operator assignment, such as `+=` and `-=`
-* the bitwise operators, such as `|` and `&`
-* the [pipe operator](guide/template-expression-operators#pipe)
-
-## Statement context
-
-As with expressions, statements can refer only to what's in the statement context
-such as an event handling method of the component instance.
-
-The *statement context* is typically the component instance.
-The *deleteHero* in `(click)="deleteHero()"` is a method of the data-bound component.
-
-<code-example path="template-syntax/src/app/app.component.html" region="context-component-statement" header="src/app/app.component.html"></code-example>
-
-The statement context may also refer to properties of the template's own context.
-In the following examples, the template `$event` object,
-a [template input variable](guide/built-in-directives#template-input-variable) (`let hero`),
-and a [template reference variable](guide/template-reference-variables) (`#heroForm`)
-are passed to an event handling method of the component.
-
-<code-example path="template-syntax/src/app/app.component.html" region="context-var-statement" header="src/app/app.component.html"></code-example>
-
-Template context names take precedence over component context names.
-In `deleteHero(hero)` above, the `hero` is the template input variable,
-not the component's `hero` property.
-
-## Statement guidelines
-
-Template statements cannot refer to anything in the global namespace. They
-can't refer to `window` or `document`.
-They can't call `console.log` or `Math.max`.
-
-As with expressions, avoid writing complex template statements.
-A method call or simple property assignment should be the norm.
