build(docs-infra): use pinned dependencies when possible in ng-packages-installer (#28510)

Previously, `ng-packages-installer` would replace the version ranges for
all dependencies that were peer dependencies of an Angular package with
the version range used in the Angular package. This effectively meant
that the pinned version (from `yarn.lock`) for that dependency was
ignored (even if the pinned version satisfied the new version range).

This commit reduces non-determinism in CI jobs using the locally built
Angular packages by always using pinned versions of dependencies for
Angular package peer dependencies if possible.

For example, assuming the following versions for the RxJS dependency:

- **aio/package.json**: `rxjs: ^6.3.0`
- **aio/yarn.lock**: `rxjs@^6.3.0: 6.3.3`
- **@angular/core#peerDependencies**: `rxjs: ^6.0.0`

...the following versions would be used with `ng-packages-installer`:

- Before this commit:
  - **aio/package.json**: `rxjs: ^6.0.0`
  - **node_modules/rxjs/**: `6.4.0` (latest version satisfying `^6.0.0`)
- After this commit:
  - **aio/package.json**: `rxjs: ^6.3.0`
  - **node_modules/rxjs/**: `6.3.3` (because it satisfies `^6.0.0`)

-# BuildKite configuration
-
-This folder contains configuration for the [BuildKite](https://buildkite.com) based CI checks for 
-this repository.
-
-BuildKite is a CI provider that provides build coordination and reports while we provide the 
-infrastructure.
-
-CI runs are triggered by new PRs and will show up on the GitHub checks interface, along with the 
-other current CI solutions.
-
-Currently it is only used for tests on Windows platforms.
-
-
-## The build pipeline
-
-BuildKite uses a pipeline for each repository. The `pipeline.yml` file defines pipeline 
-[build steps](https://buildkite.com/docs/pipelines/defining-steps) for this repository.
-
-Run results can be seen in the GitHub checks interface and in the 
-[pipeline dashboard](https://buildkite.com/angular/angular).
-
-Although most configuration is done via `pipeline.yml`, some options are only available
-in the online [pipeline settings](https://buildkite.com/angular/angular/settings).
-
-
-## Infrastructure
-
-BuildKite does not provide the host machines where the builds runs, providing instead the
-[BuildKite Agent](https://buildkite.com/docs/agent/v3) that should be run our own infrastructure.
-
-
-### Agents
-
-This agent polls the BuildKite API for builds, runs them, and reports back the results.
-Agents are the unit of concurrency: each agent can run one build at any given time. 
-Adding agents allows more builds to be ran at the same time.
-
-Individual agents can have tags, and pipeline steps can target only agents with certain tags via the
-`agents` field in `pipeline.yml`.
-For example: agents on Windows machines are tagged as `windows`, and the Windows specific build 
-steps list `windows: true` in their `agents` field.
-
-You can see the current agent pool, along with their tags, in the 
-[agents list](https://buildkite.com/organizations/angular/agents).
-
-
-### Our host machines
-
-We use [Google Cloud](https://cloud.google.com/) as our cloud provider, under the 
-[Angular project](https://console.cloud.google.com/home/dashboard?project=internal-200822).
-To access this project you need need to be logged in with a Google account that's a member of 
-team@angular.io. 
-For googlers this may be your google.com account, for others it is an angular.io account.
-
-In this project we have a number of Windows VMs running, each of them with several agents.
-The `provision-windows-buildkite.ps1` file contains instructions on how to create new host VMs that
-are fully configured to run the BuildKite agents as services.
-
-Our pipeline uses [docker-buildkite-plugin](https://github.com/buildkite-plugins/docker-buildkite-plugin)
-to run build steps inside docker containers.
-This way we achieve isolation and hermeticity.
-
-The `Dockerfile` file describes a custom Docker image that includes NodeJs, Yarn, and the Bazel 
-pre-requisites on Windows.
-
-To upload a new version of the docker image, follow any build instructions in `Dockerfile` and then
-run `docker build -t angular/node-bazel-windows:NEW_VERSION`, followed by 
-`docker push angular/node-bazel-windows:NEW_VERSION`. 
-After being pushed it should be available online, and you can use the new version in `pipeline.yml`.
-
-
-## Caretaker 
-
-BuildKite status can be found at https://www.buildkitestatus.com/.
-
-Issues related to the BuildKite setup should be escalated to the Tools Team via the current 
-caretaker, followed by Alex Eagle and Filipe Silva.
-
-Support requests should be submitted via email to support@buildkite.com and cc Igor, Misko, Alex,
-Jeremy and Manu
-
-
-## Rollout strategy
-
-At the moment our BuildKite CI uses 1 host VM running 4 agents, thus being capable of 4 concurrent 
-builds.
-The only test running is `bazel test //tools/ts-api-guardian:all`, and the PR check is not 
-mandatory.
-
-In the future we should add cache support to speed up the initial `yarn` install, and also Bazel
-remote caching to speed up Bazel builds.
-
-After the current setup is verified as stable and reliable the GitHub PR check can become mandatory.
-
-The tests ran should also be expanded to cover most, if not all, of the Bazel tests.

-<h1 class="no-toc">CLI Command Reference</h1>
-
-The Angular CLI is a command-line interface tool that you use to initialize, develop, scaffold, and maintain Angular applications. You can use the tool directly in a command shell, or indirectly through an interactive UI such as [Angular Console](https://angularconsole.com).
-
-## Installing Angular CLI
-
-Major versions of Angular CLI follow the supported major version of Angular, but minor versions can be released separately.
-
-Install the CLI using the `npm` package manager:
-<code-example format="." language="bash">
-npm install -g @angular/cli
-</code-example>
-
-For details about changes between versions, and information about updating from previous releases,
-see the Releases tab on GitHub: https://github.com/angular/angular-cli/releases
-
-## Basic workflow
-
-Invoke the tool on the command line through the `ng` executable.
-Online help is available on the command line.
-Enter the following to list commands or options for a given command (such as [generate](cli/generate)) with a short description.
-
-<code-example format="." language="bash">
-ng help
-ng generate --help
-</code-example>
-
-To create, build, and serve a new, basic Angular project on a development server, go to the parent directory of your new workspace use the following commands:
-
-<code-example format="." language="bash">
-ng new my-first-project
-cd my-first-project
-ng serve
-</code-example>
-
-In your browser, open http://localhost:4200/ to see the new app run.
-When you use the [ng serve](cli/serve) command to build an app and serve it locally, the server automatically rebuilds the app and reloads the page when you change any of the source files.
-
-## Workspaces and project files
-
-The [ng new](cli/new) command creates an *Angular workspace* folder and generates a new app skeleton.
-A workspace can contain multiple apps and libraries.
-The initial app created by the [ng new](cli/new) command is at the top level of the workspace.
-When you generate an additional app or library in a workspace, it goes into a `projects/` subfolder.
-
-A newly generated app contains the source files for a root module, with a root component and template.
-Each app has a `src` folder that contains the logic, data, and assets.
-
-You can edit the generated files directly, or add to and modify them using CLI commands.
-Use the [ng generate](cli/generate) command to add new files for additional components and services, and code for new pipes, directives, and so on.
-Commands such as [add](cli/add) and [generate](cli/generate), which create or operate on apps and libraries, must be executed from within a workspace or project folder.
-
-* See more about the [Workspace file structure](guide/file-structure).
-
-### Workspace and project configuration
-
-A single workspace configuration file, `angular.json`, is created at the top level of the workspace.
-This is where you can set per-project defaults for CLI command options, and specify configurations to use when the CLI builds a project for different targets.
-
-The [ng config](cli/config) command lets you set and retrieve configuration values from the command line, or you can edit the `angular.json` file directly.
-Note that option names in the configuration file must use [camelCase](guide/glossary#case-types), while option names supplied to commands can use either camelCase or dash-case.
-
-* See more about [Workspace Configuration](guide/workspace-config).
-* See the [complete schema](https://github.com/angular/angular-cli/wiki/angular-workspace) for `angular.json`.
-
-## CLI command-language syntax
-
-Command syntax is shown as follows:
-
-`ng` *commandNameOrAlias* *requiredArg* [*optionalArg*] `[options]`
-
-* Most commands, and some options, have aliases. Aliases are shown in the syntax statement for each command.
-
-* Option names are prefixed with a double dash (--).
-    Option aliases are prefixed with a single dash (-).
-    Arguments are not prefixed.
-    For example: `ng build my-app -c production`
-
-* Typically, the name of a generated artifact can be given as an argument to the command or specified with the --name option.
-
-* Argument and option names can be given in either
-[camelCase or dash-case](guide/glossary#case-types).
-`--myOptionName` is equivalent to `--my-option-name`.
-
-### Boolean and enumerated options
-
-Boolean options have two forms: `--thisOption` sets the flag, `--noThisOption` clears it.
-If neither option is supplied, the flag remains in its default state, as listed in the reference documentation.
-
-Allowed values are given with each enumerated option description, with the default value in **bold**.
-
-### Relative paths
-
-Options that specify files can be given as absolute paths, or as paths relative to the current working directory, which is generally either the workspace or project root.
-
-### Schematics
-
-The [ng generate](cli/generate) and  [ng add](cli/add) commands take as an argument the artifact or library to be generated or added to the current project.
-In addition to any general options, each artifact or library defines its own options in a *schematic*.
-Schematic options are supplied to the command in the same format as immediate command options.

-## Configuration inheritance with extends
-Similar to TypeScript Compiler, Angular Compiler also supports `extends` in the `tsconfig.json` on `angularCompilerOptions`. A tsconfig file can inherit configurations from another file using the `extends` property.
- The `extends` is a top level property parallel to `compilerOptions` and `angularCompilerOptions`. 
- The configuration from the base file are loaded first, then overridden by those in the inheriting config file.
- Example:
-```json
-{
-  "extends": "../tsconfig.base.json",
-  "compilerOptions": {
-    "experimentalDecorators": true,
-    ...
-  },
-  "angularCompilerOptions": {
-    "fullTemplateTypeCheck": true,
-    "preserveWhitespaces": true,
-    ...
-  }
-}
-```
- More information about tsconfig extends can be found in the [TypeScript Handbook](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html).

-# Building and serving Angular apps
-
-This page discusses build-specific configuration options for Angular projects.
-
-{@a app-environments}
-
-## Configuring application environments
-
-You can define different named build configurations for your project, such as *stage* and *production*, with different defaults. 
-
-Each named build configuration can have defaults for any of the options that apply to the various build targets, such as `build`, `serve`, and `test`. The [Angular CLI](cli) `build`, `serve`, and `test` commands can then replace files with appropriate versions for your intended target environment.
-
-The following figure shows how a project has multiple build targets, which can be executed using the named configurations that you define.
-
-<figure>
-  <img src="generated/images/guide/build/build-config-targets.gif" alt="build configurations and targets">
-</figure>
-
-### Configure environment-specific defaults
-
-A project's `src/environments/` folder contains the base configuration file, `environment.ts`, which provides a default environment. 
-You can add override defaults for additional environments, such as production and staging, in target-specific configuration files. 
-
-For example:
-
-```
-└──myProject/src/environments/
-                   └──environment.ts
-                   └──environment.prod.ts
-                   └──environment.stage.ts
-```
-
-The base file `environment.ts`, contains the default environment settings. For example:
-
-```
-export const environment = {
-  production: false
-};
-```
-
-The `build` command uses this as the build target when no environment is specified. 
-You can add further variables, either as additional properties on the environment object, or as separate objects. 
-For example, the following adds a default for a variable to the default environment:
-
-```
-export const environment = {
-  production: false,
-  apiUrl: 'http://my-api-url'
-};
-```
-
-You can add target-specific configuration files, such as `environment.prod.ts`. 
-The following sets content sets default values for the production build target:
-
-```
-export const environment = {
-  production: true
-  apiUrl: 'http://my-prod-url'
-};
-```
-
-### Using environment-specific variables in your app
-
-The following application structure configures build targets for production and staging environments:
-
-```
-└── src
-    └── app
-        ├── app.component.html
-        └── app.component.ts
-    └── environments
-        ├── environment.prod.ts
-        ├── environment.staging.ts
-        └── environment.ts
-```
-
-To use the environment configurations you have defined, your components must import the original environments file:
-
-```
-import { environment } from './../environments/environment';
-```
-
-This ensures that the build and serve commands can find the configurations for specific build targets.
-
-The following code in the component file (`app.component.ts`) uses an environment variable defined in the configuration files.
-
-```
-import { Component } from '@angular/core';
-import { environment } from './../environments/environment';
-
-@Component({
-  selector: 'app-root',
-  templateUrl: './app.component.html',
-  styleUrls: ['./app.component.css']
-})
-export class AppComponent {
-  constructor() {
-    console.log(environment.production); // Logs false for default environment
-  }
-  title = 'app works!';
-}
-```
-{@a file-replacement}
-
-## Configure target-specific file replacements
-
-The main CLI configuration file, `angular.json`, contains a `fileReplacements` section in the configuration for each build target, which allows you to replace any file with a target-specific version of that file. 
-This is useful for including target-specific code or variables in a build that targets a specific environment, such as production or staging.
-
-By default no files are replaced. 
-You can add file replacements for specific build targets. 
-For example:
-
-```
-"configurations": {
-  "production": {
-    "fileReplacements": [
-      {
-        "replace": "src/environments/environment.ts",
-        "with": "src/environments/environment.prod.ts"
-      }
-    ],
-    ...
-```
-
-This means that when you build your production configuration (using `ng build --prod` or `ng build --configuration=production`), the `src/environments/environment.ts` file is replaced with the target-specific version of the file, `src/environments/environment.prod.ts`.
-
-You can add additional configurations as required. To add a staging environment, create a copy of `src/environments/environment.ts` called `src/environments/environment.staging.ts`, then add a `staging` configuration to `angular.json`:
-
-```
-"configurations": {
-  "production": { ... },
-  "staging": {
-    "fileReplacements": [
-      {
-        "replace": "src/environments/environment.ts",
-        "with": "src/environments/environment.staging.ts"
-      }
-    ]
-  }
-}
-```
-
-You can add more configuration options to this target environment as well. 
-Any option that your build supports can be overridden in a build target configuration.
-
-To build using the staging configuration, run the following command:
-
-<code-example language="sh" class="code-shell">
- ng build --configuration=staging
-</code-example>
-
-You can also configure the `serve` command to use the targeted build configuration if you add it to the "serve:configurations" section of `angular.json`:
-
-```
-"serve": {
-  "builder": "@angular-devkit/build-angular:dev-server",
-  "options": {
-    "browserTarget": "your-project-name:build"
-  },
-  "configurations": {
-    "production": {
-      "browserTarget": "your-project-name:build:production"
-    },
-    "staging": {
-      "browserTarget": "your-project-name:build:staging"
-    }
-  }
-},
-```
-
-{@a size-budgets}
-
-## Configure size budgets
-
-As applications grow in functionality, they also grow in size. 
-The CLI allows you to set size thresholds in your configuration to ensure that parts of your application stay within size boundaries that you define.
-
-Define your size boundaries in the CLI configuration file, `angular.json`, in a `budgets` section for each [configured environment](#app-environments). 
-
-```
-{
-  ...
-  "configurations": {
-    "production": {
-      ...
-      budgets: []
-    }
-  }
-}
-```
-
-You can specify size budgets for the entire app, and for particular parts. 
-Each budget entry configures a budget of a given type. 
-Specify size values in the following formats:
-
-* 123 or 123b: Size in bytes
-
-* 123kb: Size in kilobytes
-
-* 123mb: Size in megabytes
-
-* 12%: Percentage of size relative to baseline. (Not valid for baseline values.)
-
-When you configure a budget, the build system warns or reports and error when a given part of the app reaches or exceeds a boundary size that you set.
-
-Each budget entry is a JSON object with the following properties:
-
-<table>
-  <tr>
-    <th>Property</th>
-    <th>Value</th>
-  </tr>
-
-  <tr>
-    <td>type</td>
-    <td>The type of budget. One of:
-
-        * bundle - The size of a specific bundle.
-        * initial - The initial size of the app.

-        * all - The size of the entire app.
-        * anyScript - The size of any one script.
-        * any - The size of any file.

-{@a browser-compat}
-
-## Configuring browser compatibility
-
-The CLI uses [Autoprefixer](https://github.com/postcss/autoprefixer) to ensure compatibility with different browser and browser versions. 
-You may find it necessary to target specific browsers or exclude certain browser versions from your build.
-
-Internally, Autoprefixer relies on a library called [Browserslist](https://github.com/browserslist/browserslist) to figure out which browsers to support with prefixing. 
-Browserlist looks for configuration options in a `browserlist` property of the package configuration file, or in a configuration file named `.browserslistrc`. 
-Autoprefixer looks for the Browserlist configuration when it prefixes your CSS. 
-
-* You can tell Autoprefixer what browsers to target by adding a browserslist property to the package configuration file, `package.json`:
-```
- "browserslist": [
-   "> 1%",
-   "last 2 versions"
- ]
-```
-
-* Alternatively, you can add a new file, `.browserslistrc`, to the project directory, that specifies browsers you want to support:
-```
- ### Supported Browsers
- > 1%
- last 2 versions
-```
-
-See the [browserslist repo](https://github.com/browserslist/browserslist) for more examples of how to target specific browsers and versions.
-
-<div class="alert is-helpful">
-Backward compatibility
-
-If you want to produce a progressive web app and are using [Lighthouse](https://developers.google.com/web/tools/lighthouse/) to grade the project, add the following browserslist entry to your `package.json` file, in order to eliminate the [old flexbox](https://developers.google.com/web/tools/lighthouse/audits/old-flexbox) prefixes:
-
-```
-"browserslist": [
-  "last 2 versions",
-  "not ie <= 10",
-  "not ie_mob <= 10"
-]
-```

-
-{@a proxy}
-
-## Proxying to a backend server
-
-You can use the [proxying support](https://webpack.js.org/configuration/dev-server/#devserver-proxy) in the `webpack` dev server to divert certain URLs to a backend server, by passing a file to the `--proxy-config` build option.
-For example, to divert all calls for `http://localhost:4200/api` to a server running on `http://localhost:3000/api`, take the following steps.
-
-1. Create a file `proxy.conf.json` in the projects `src/` folder, next to `package.json`.
-
-1. Add the following content to the new proxy file:
-    ```
-    {
-      "/api": {
-        "target": "http://localhost:3000",
-        "secure": false
-      }
-    }
-    ```
-
-1. In the CLI configuration file, `angular.json`, add the `proxyConfig` option to the `serve` target:
-    ```
-    ...
-    "architect": {
-      "serve": {
-        "builder": "@angular-devkit/build-angular:dev-server",
-        "options": {
-          "browserTarget": "your-application-name:build",
-          "proxyConfig": "src/proxy.conf.json"
-        },
-    ...
-    ```
-
-1. To run the dev server with this proxy configuration, call `ng serve`. 
-
-You can edit the proxy configuration file to add configuration options; some examples are given below. 
-For a description of all options, see [webpack DevServer documentation](https://webpack.js.org/configuration/dev-server/#devserver-proxy).
-
-Note that if you edit the proxy configuration file, you must relaunch the `ng serve` process to make your changes effective.
-
-### Rewrite the URL path
-
-The `pathRewrite` proxy configuration option lets you rewrite the URL path at run time. 
-For example, you can specify the following `pathRewrite` value to the proxy configuration to remove "api" from the end of a path.
-
-```
-{
-  "/api": {
-    "target": "http://localhost:3000",
-    "secure": false,
-    "pathRewrite": {
-      "^/api": ""
-    }
-  }
-}
-```
-
-If you need to access a backend that is not on `localhost`, set the `changeOrigin` option as well. For example:
-
-```
-{
-  "/api": {
-    "target": "http://npmjs.org",
-    "secure": false,
-    "pathRewrite": {
-      "^/api": ""
-    },
-    "changeOrigin": true
-  }
-}
-```
-
-To help determine whether your proxy is working as intended, set the `logLevel` option. For example:
-
-```
-{
-  "/api": {
-    "target": "http://localhost:3000",
-    "secure": false,
-    "pathRewrite": {
-      "^/api": ""
-    },
-    "logLevel": "debug"
-  }
-}
-```
-
-Proxy log levels are `info` (the default), `debug`, `warn`, `error`, and `silent`.
-
-### Proxy multiple entries
-
-You can  proxy multiple entries to the same target by defining the configuration in JavaScript.
-
-Set the proxy configuration file to `proxy.conf.js` (instead of `proxy.conf.json`), and specify configuration files as in the following example.
-
-```
-const PROXY_CONFIG = [
-    {
-        context: [
-            "/my",
-            "/many",
-            "/endpoints",
-            "/i",
-            "/need",
-            "/to",
-            "/proxy"
-        ],
-        target: "http://localhost:3000",
-        secure: false
-    }
-]
-
-module.exports = PROXY_CONFIG;
-```
-
-In the CLI configuration file, `angular.json`, point to the JavaScript proxy configuration file:
-
-```
-...
-"architect": {
-  "serve": {
-    "builder": "@angular-devkit/build-angular:dev-server",
-    "options": {
-      "browserTarget": "your-application-name:build",
-      "proxyConfig": "src/proxy.conf.js"
-    },
-...
-```
-
-### Bypass the proxy
-
-If you need to optionally bypass the proxy, or dynamically change the request before it's sent, add the bypass option, as shown in this JavaScript example.
-
-```
-const PROXY_CONFIG = {
-    "/api/proxy": {
-        "target": "http://localhost:3000",
-        "secure": false,
-        "bypass": function (req, res, proxyOptions) {
-            if (req.headers.accept.indexOf("html") !== -1) {
-                console.log("Skipping proxy for browser request.");
-                return "/index.html";
-            }
-            req.headers["X-Custom-Header"] = "yes";
-        }
-    }
-}
-
-module.exports = PROXY_CONFIG;
-```
-
-### Using corporate proxy
-
-If you work behind a corporate proxy, the cannot directly proxy calls to any URL outside your local network. 
-In this case, you can configure the backend proxy to redirect calls through your corporate proxy using an agent:
-
-<code-example language="none" class="code-shell">
-npm install --save-dev https-proxy-agent
-</code-example>
-
-When you define an environment variable `http_proxy` or `HTTP_PROXY`, an agent is automatically added to pass calls through your corporate proxy when running `npm start`.
-
-Use the following content in the JavaScript configuration file.
-
-```
-var HttpsProxyAgent = require('https-proxy-agent');
-var proxyConfig = [{
-  context: '/api',
-  target: 'http://your-remote-server.com:3000',
-  secure: false
-}];
-
-function setupForCorporateProxy(proxyConfig) {
-  var proxyServer = process.env.http_proxy || process.env.HTTP_PROXY;
-  if (proxyServer) {
-    var agent = new HttpsProxyAgent(proxyServer);
-    console.log('Using corporate proxy server: ' + proxyServer);
-    proxyConfig.forEach(function(entry) {
-      entry.agent = agent;
-    });
-  }
-  return proxyConfig;
-}
-
-module.exports = setupForCorporateProxy(proxyConfig);

-## Server configuration
-
-This section covers changes you may have make to the server or to files deployed to the server.
-
-{@a fallback}
-
-### Routed apps must fallback to `index.html`
-
-Angular apps are perfect candidates for serving with a simple static HTML server.
-You don't need a server-side engine to dynamically compose application pages because
-Angular does that on the client-side.
-
-If the app uses the Angular router, you must configure the server
-to return the application's host page (`index.html`) when asked for a file that it does not have.
-
-{@a deep-link}
-
-A routed application should support "deep links".
-A _deep link_ is a URL that specifies a path to a component inside the app.
-For example, `http://www.mysite.com/heroes/42` is a _deep link_ to the hero detail page
-that displays the hero with `id: 42`.
-
-There is no issue when the user navigates to that URL from within a running client.
-The Angular router interprets the URL and routes to that page and hero.
-
-But clicking a link in an email, entering it in the browser address bar,
-or merely refreshing the browser while on the hero detail page &mdash;
-all of these actions are handled by the browser itself, _outside_ the running application.
-The browser makes a direct request to the server for that URL, bypassing the router.
-
-A static server routinely returns `index.html` when it receives a request for `http://www.mysite.com/`.
-But it rejects `http://www.mysite.com/heroes/42` and returns a `404 - Not Found` error *unless* it is
-configured to return `index.html` instead.

-When you are designing and developing applications, you typically use `ng serve` to build your app for fast, local, iterative development.
-When you are ready to deploy, however, you must use the `ng build` command to build the app and deploy the build artifacts elsewhere.

+## Server configuration
+
+This section covers changes you may have make to the server or to files deployed to the server.
+
+{@a fallback}
+
+### Routed apps must fallback to `index.html`
+
+Angular apps are perfect candidates for serving with a simple static HTML server.
+You don't need a server-side engine to dynamically compose application pages because
+Angular does that on the client-side.
+
+If the app uses the Angular router, you must configure the server
+to return the application's host page (`index.html`) when asked for a file that it does not have.
+
+{@a deep-link}
+
+
+A routed application should support "deep links".
+A _deep link_ is a URL that specifies a path to a component inside the app.
+For example, `http://www.mysite.com/heroes/42` is a _deep link_ to the hero detail page
+that displays the hero with `id: 42`.
+
+There is no issue when the user navigates to that URL from within a running client.
+The Angular router interprets the URL and routes to that page and hero.
+
+But clicking a link in an email, entering it in the browser address bar,
+or merely refreshing the browser while on the hero detail page &mdash;
+all of these actions are handled by the browser itself, _outside_ the running application.
+The browser makes a direct request to the server for that URL, bypassing the router.
+
+A static server routinely returns `index.html` when it receives a request for `http://www.mysite.com/`.
+But it rejects `http://www.mysite.com/heroes/42` and returns a `404 - Not Found` error *unless* it is
+configured to return `index.html` instead.
+
+#### Fallback configuration examples
+
+There is no single configuration that works for every server.
+The following sections describe configurations for some of the most popular servers.
+The list is by no means exhaustive, but should provide you with a good starting point.
+
+#### Development servers
+
+* [Lite-Server](https://github.com/johnpapa/lite-server): the default dev server installed with the
+[Quickstart repo](https://github.com/angular/quickstart) is pre-configured to fallback to `index.html`.
+
+
+* [Webpack-Dev-Server](https://github.com/webpack/webpack-dev-server):  setup the
+`historyApiFallback` entry in the dev server options as follows:
+
+  <code-example>
+    historyApiFallback: {
+      disableDotRule: true,
+      htmlAcceptHeaders: ['text/html', 'application/xhtml+xml']
+    }
+  </code-example>
+
+
+#### Production servers
+
+* [Apache](https://httpd.apache.org/): add a
+[rewrite rule](http://httpd.apache.org/docs/current/mod/mod_rewrite.html) to the `.htaccess` file as shown
+  (https://ngmilk.rocks/2015/03/09/angularjs-html5-mode-or-pretty-urls-on-apache-using-htaccess/):
+
+  <code-example format=".">
+    RewriteEngine On
+    &#35 If an existing asset or directory is requested go to it as it is
+    RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]
+    RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
+    RewriteRule ^ - [L]
+
+    &#35 If the requested resource doesn't exist, use index.html
+    RewriteRule ^ /index.html
+  </code-example>
+
+
+* [NGinx](http://nginx.org/): use `try_files`, as described in
+[Front Controller Pattern Web Apps](https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/#front-controller-pattern-web-apps),
+modified to serve `index.html`:
+
+  <code-example format=".">
+    try_files $uri $uri/ /index.html;
+  </code-example>
+
+
+* [IIS](https://www.iis.net/): add a rewrite rule to `web.config`, similar to the one shown
+[here](http://stackoverflow.com/a/26152011/2116927):
+
+  <code-example format='.'>
+    &lt;system.webServer&gt;
+      &lt;rewrite&gt;
+        &lt;rules&gt;
+          &lt;rule name="Angular Routes" stopProcessing="true"&gt;
+            &lt;match url=".*" /&gt;
+            &lt;conditions logicalGrouping="MatchAll"&gt;
+              &lt;add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /&gt;
+              &lt;add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /&gt;
+            &lt;/conditions&gt;
+            &lt;action type="Rewrite" url="/index.html" /&gt;
+          &lt;/rule&gt;
+        &lt;/rules&gt;
+      &lt;/rewrite&gt;
+    &lt;/system.webServer&gt;
+
+  </code-example>
+
+
+* [GitHub Pages](https://pages.github.com/): you can't
+[directly configure](https://github.com/isaacs/github/issues/408)
+the GitHub Pages server, but you can add a 404 page.
+Copy `index.html` into `404.html`.
+It will still be served as the 404 response, but the browser will process that page and load the app properly.
+It's also a good idea to
+[serve from `docs/` on master](https://help.github.com/articles/configuring-a-publishing-source-for-github-pages/#publishing-your-github-pages-site-from-a-docs-folder-on-your-master-branch)
+and to
+[create a `.nojekyll` file](https://www.bennadel.com/blog/3181-including-node-modules-and-vendors-folders-in-your-github-pages-site.htm)
+
+
+* [Firebase hosting](https://firebase.google.com/docs/hosting/): add a
+[rewrite rule](https://firebase.google.com/docs/hosting/url-redirects-rewrites#section-rewrites).
+
+  <code-example format=".">
+    "rewrites": [ {
+      "source": "**",
+      "destination": "/index.html"
+    } ]
+
+  </code-example>
+
+{@a cors}
+
+### Requesting services from a different server (CORS)
+
+Angular developers may encounter a
+<a href="https://en.wikipedia.org/wiki/Cross-origin_resource_sharing" title="Cross-origin resource sharing">
+<i>cross-origin resource sharing</i></a> error when making a service request (typically a data service request)

-# Workspace and project file structure
-
-You develop apps in the context of an Angular [workspace](guide/glossary#workspace). A workspace contains the files for one or more [projects](guide/glossary#project). A project is the set of files that comprise a standalone app, a library, or a set of end-to-end (e2e) tests. 
-
-The Angular CLI command `ng new <project_name>` gets you started. 
-When you run this command, the CLI installs the necessary Angular npm packages and other dependencies in a new workspace, with a root folder named *project_name*. 
-It also creates the following workspace and starter project files:
-
-* An initial skeleton app project, also called *project_name* (in the `src/` subfolder).
-* An end-to-end test project (in the `e2e/` subfolder).
-* Related configuration files.
-
-The initial app project contains a simple Welcome app, ready to run. 
-
-## Workspace files
-
-The top level of the workspace contains a number of workspace-wide configuration files.
-
-| WORKSPACE CONFIG FILES    | PURPOSE |
-| :--------------------- | :------------------------------------------|
-| `.editorconfig`        | Configuration for code editors. See [EditorConfig](https://editorconfig.org/). |
-| `.gitignore`           | Specifies intentionally untracked files that [Git](https://git-scm.com/) should ignore. |
-| `angular.json`         | CLI configuration defaults for all projects in the workspace, including configuration options for build, serve, and test tools that the CLI uses, such as [TSLint](https://palantir.github.io/tslint/), [Karma](https://karma-runner.github.io/), and [Protractor](http://www.protractortest.org/). For details, see [Angular Workspace Configuration](guide/workspace-config). |
-| `node_modules`         | Provides [npm packages](guide/npm-packages) to the entire workspace. |
-| `package.json`         | Configures [npm package dependencies](guide/npm-packages) that are available to all projects in the workspace. See [npm documentation](https://docs.npmjs.com/files/package.json) for the specific format and contents of this file. |
-| `package-lock.json`    | Provides version information for all packages installed into `node_modules` by the npm client. See [npm documentation](https://docs.npmjs.com/files/package-lock.json) for details. If you use the yarn client, this file will be [yarn.lock](https://yarnpkg.com/lang/en/docs/yarn-lock/) instead. |
-| `tsconfig.json`        | Default [TypeScript](https://www.typescriptlang.org/) configuration for apps in the workspace, including TypeScript and Angular template compiler options. See [TypeScript Configuration](guide/typescript-configuration). |
-| `tslint.json`          | Default [TSLint](https://palantir.github.io/tslint/) configuration for apps in the workspace. |
-| `README.md`            | Introductory documentation. |
-
-All projects within a workspace share a [CLI configuration context](guide/workspace-config). 
-Project-specific [TypeScript](https://www.typescriptlang.org/) configuration files inherit from the workspace-wide `tsconfig.*.json`, and app-specific [TSLint](https://palantir.github.io/tslint/) configuration files inherit from the workspace-wide `tslint.json`.
-
-### Default app project files
-
-The CLI command `ng new my-app` creates a workspace folder named "my-app" and generates a new app skeleton. 
-This initial app is the *default app* for CLI commands (unless you change the default after creating additional apps). 
-
-A newly generated app contains the source files for a root module, with a root component and template. 
-When the workspace file structure is in place, you can use the `ng generate` command on the command line to add functionality and data to the initial app.
-
-<div class="alert is-helpful">
-
-   Besides using the CLI on the command line, you can also use an interactive development environment like [Angular Console](https://angularconsole.com/), or manipulate files directly in the app's source folder and configuration files.
-
-</div>
-
-The `src/` subfolder contains the source files (app logic, data, and assets), along with configuration files for the initial app.
-Workspace-wide `node_modules` dependencies are visible to this project.
-
-| APP SOURCE & CONFIG FILES    | PURPOSE |
-| :--------------------- | :------------------------------------------|
-| `app/`                 | Contains the component files in which your app logic and data are defined. See details in [App source folder](#app-src) below. |
-| `assets/`              | Contains image files and other asset files to be copied as-is when you build your application. | 
-| `environments/`        | Contains build configuration options for particular target environments. By default there is an unnamed standard development environment and a production ("prod") environment. You can define additional target environment configurations. |
-| `browserlist`          | Configures sharing of target browsers and Node.js versions among various front-end tools. See [Browserlist on GitHub](https://github.com/browserslist/browserslist) for more information.  |
-| `favicon.ico`          | An icon to use for this app in the bookmark bar. |
-| `index.html`           | The main HTML page that is served when someone visits your site. The CLI automatically adds all JavaScript and CSS files when building your app, so you typically don't need to add any `<script>` or` <link>` tags here manually. |
-| `main.ts`              | The main entry point for your app. Compiles the application with the [JIT compiler](https://angular.io/guide/glossary#jit) and bootstraps the application's root module (AppModule) to run in the browser. You can also use the [AOT compiler](https://angular.io/guide/aot-compiler) without changing any code by appending the `--aot` flag to the CLI `build` and `serve` commands. |
-| `polyfills.ts`         | Provides polyfill scripts for browser support. |
-| `styles.sass`          | Lists CSS files that supply styles for a project. The extension reflects the style preprocessor you have configured for the project. |
-| `test.ts`              | The main entry point for your unit tests, with some Angular-specific configuration. You don't typically need to edit this file. |
-| `tsconfig.app.json`   | Inherits from the workspace-wide `tsconfig.json` file. |
-| `tsconfig.spec.json`  | Inherits from the workspace-wide `tsconfig.json` file. |
-| `tslint.json`         | Inherits from the workspace-wide `tslint.json` file. |
-
-### Default app project e2e files
-
-An `e2e/` subfolder contains configuration and source files for a set of end-to-end tests that correspond to the initial app.

-    protractor.conf.js  (test-tool config)
-    tsconfig.e2e.json   (TypeScript config inherits from workspace tsconfig.json)
-</code-example>
-
-### Project folders for additional apps and libraries
-
-When you generate new projects in a workspace, 
-the CLI creates a new *workspace*`/projects` folder, and adds the generated files there.
-
-When you generate an app (`ng generate application my-other-app`), the CLI adds folders under `projects/` for both the app and its corresponding end-to-end tests. Newly generated libraries are also added under `projects/`.

-## App source folder
-
-Inside the `src/` folder, the `app/` folder contains your app's logic and data. Angular components, templates, and styles go here. An `assets/` subfolder contains images and anything else your app needs. Files at the top level of `src/` support testing and running your app.
-
-| APP SOURCE FILES | PURPOSE |
-| :-------------------------- | :------------------------------------------|
-| `app/app.component.ts`      | Defines the logic for the app's root component, named `AppComponent`. The view associated with this root component becomes the root of the [view hierarchy](guide/glossary#view-hierarchy) as you add components and services to your app. |
-| `app/app.component.html`    | Defines the HTML template associated with the root `AppComponent`. |
-| `app/app.component.css`     | Defines the base CSS stylesheet for the root `AppComponent`. |
-| `app/app.component.spec.ts` | Defines a unit test for the root `AppComponent`. |
-| `app/app.module.ts`         | Defines the root module, named `AppModule`, that tells Angular how to assemble the application. Initially declares only the `AppComponent`. As you add more components to the app, they must be declared here. |
-| `assets/*`                  | Contains image files and other asset files to be copied as-is when you build your application. |

+Handling user input with forms is the cornerstone of many common applications. Applications use forms to enable users log in, to update a profile, to enter sensitive information, and to perform many other data-entry tasks. 
 
 Angular provides two different approaches to handling user input through forms: reactive and template-driven. Both capture user input events from the view, validate the user input, create a form model and data model to update, and provide a way to track changes. 
 
-Reactive and template-driven forms process and manage form data differently. Each offers different advantages.
+Reactive and template-driven forms differ, however, in how they do the work of processing and managing forms and form data. Each offers different advantages.

-* **Template-driven forms** are useful for adding a simple form to an app, such as an email list signup form. They're easy to add to an app, but they don't scale as well as reactive forms. If you have very basic form requirements and logic that can be managed solely in the template, use template-driven forms.

 ## Mutability
 
-The change tracking method plays a role in the efficiency of your application.
+How changes are tracked plays a role in the efficiency of your application.
 
-
-* **Reactive forms** keep the data model pure by providing it as an immutable data structure. Each time a change is triggered on the data model, the `FormControl` instance returns a new data model rather than updating the existing data model. This gives you the ability to track unique changes to the data model through the control's observable. This provides one way for change detection to be more efficient because it only needs to update on unique changes. It also follows reactive patterns that integrate with observable operators to transform data.
-
-* **Template-driven** forms rely on mutability with two-way data binding to update the data model in the component as changes are made in the template. Because there are no unique changes to track on the data model when using two-way data binding, change detection is less efficient at determining when updates are required.

 ## Scalability
 
 If forms are a central part of your application, scalability is very important. Being able to reuse form models across components is critical.
 
+- **Reactive forms** make creating large scale forms easier by providing access to low-level APIs and synchronous access to the form model.
+- **Template-driven** forms focus on simple scenarios, are not as reusable, abstract away the low-level APIs and access to the form model is  provided asynchronously. The abstraction with template-driven forms surfaces in testing also, where testing reactive forms requires less setup and no dependence on the change detection cycle when updating and validating the form and data models during testing.

Low-level API and form model access, predictability, mutability, straightforward validation and testing strategies, and scalability are all important considerations in choosing the infrastructure you use to build your forms in Angular. Template-driven forms are similar to patterns in AngularJS, but they have limitations given the criteria of many modern, large-scale Angular apps. Reactive forms minimize these limitations. Reactive forms integrate with reactive patterns already present in other areas of the Angular architecture, and complement those requirements well.
