BREAKING CHANGE:
Previously, components that would implement lifecycle interfaces would include methods
like "onChanges" or "afterViewInit." Given that components were at risk of using such
names without realizing that Angular would call the methods at different points of
the component lifecycle. This change adds an "ng" prefix to all lifecycle hook methods,
far reducing the risk of an accidental name collision.
To fix, just rename these methods:
* onInit
* onDestroy
* doCheck
* onChanges
* afterContentInit
* afterContentChecked
* afterViewInit
* afterViewChecked
* _Router Hooks_
* onActivate
* onReuse
* onDeactivate
* canReuse
* canDeactivate
To:
* ngOnInit,
* ngOnDestroy,
* ngDoCheck,
* ngOnChanges,
* ngAfterContentInit,
* ngAfterContentChecked,
* ngAfterViewInit,
* ngAfterViewChecked
* _Router Hooks_
* routerOnActivate
* routerOnReuse
* routerOnDeactivate
* routerCanReuse
* routerCanDeactivate
The names of lifecycle interfaces and enums have not changed, though interfaces
have been updated to reflect the new method names.
Closes#5036
This is part of ongoing work to make core platform-independent.
BREAKING CHANGE
All private exports from 'angular2/src/core/facade/{lang,collection,exception_handler}' should be replaced with 'angular2/src/facade/{lang,collection,exception_handler}'.
This was a poorly typed attempt to mimic TypeScript's index signatures,
which we can use instead.
This eliminates a very strange type that we were exposing to users, but
not re-exporting through our public API.
Fixes#4483
Closes#3605
BREAKING CHANGE:
- we don't mark an element as bound any more if it only contains text bindings
E.g. <div>{{hello}}</div>
This changes the indices when using `DebugElement.componentViewChildren` / `DebugElement.children`.
- `@Directive.compileChildren` was removed,
`ng-non-bindable` is now builtin and not a directive any more
- angular no more adds the `ng-binding` class to elements with bindings
- directives are now ordered as they are listed in the View.directives regarding change detection.
Previously they had an undefined order.
- the `Renderer` interface has new methods `createProtoView` and `registerComponentTemplate`. See `DomRenderer` for default implementations.
- reprojection with `ng-content` is now all or nothing per `ng-content` element
- angular2 transformer can't be used in tests that modify directive metadata.
Use `angular2/src/transform/inliner_for_test` transformer instead.
- Rename `DirectiveMetadata` into `CompileDirectiveMetadata`, merge
with `NormalizedDirectiveMetadata` and remove `ChangeDetectionMetadata`
- Store change detector factories not as array but
directly at the `CompiledTemplate` or the embedded template
to make instantiation easier later on
- Already analyze variable values and map them
to `Directive.exportAs`
- Keep the directive sort order as specified in the
`@View()` annotation
- Allow to clear the runtime cache in `StyleCompiler`
and `TemplateCompiler`
- Ignore `script` elements to match the semantics of the
current compiler
- Make all components dynamically loadable and remove
the previously introduced property `@Component#dynamicLoadable`
for now until we find a better option to configure this
- Don’t allow to specify bindings in `@View#directives` and `@View#pipes` as this was never supported by the transformer (see below for the breaking change)
BREAKING CHANGE:
- don't support DI bindings in `@View#directives` and `@View@pipes` any more in preparation of integrating the new compiler. Use `@Directive#bindings` to reexport directives under a different token instead.

By default, pipes are pure. This means that an instance of a pipe will be reused and the pipe will be called only when its arguments change.
BREAKING CHANGE
Before:
@Pipe({name: 'date'}) class DatePipe {} defines an impure pipe.
After:
@Pipe({name: 'date'}) class DatePipe {} defines a pure pipe.
@Pipe({name: 'date', pure: false}) class DatePipe {} defines an impure pipe.
Closes#3966
This change moves many APIs to the angular2/core export.
This change also automatically adds FORM_BINDINGS in
the application root injector.
BREAKING CHANGE:
Many dependencies that were previously exported from specific
APIs are now exported from angular2/core. Affected exports, which
should now be included from angular2/core include:
angular2/forms
angular2/di
angular2/directives
angular2/change_detection
angular2/bootstrap (except for dart users)
angular2/render
angular2/metadata
angular2/debug
angular2/pipes
Closes#3977
BREAKING CHANGE (maybe)
Well as long as our customers use public API this should not be a
breaking change, but we have changed import structure as well as
internal names, so it could be breaking.
import:
angular2/annotations => angular2/metadata
Classes:
*Annotations => *Metadata
renderer.DirectiveMetadata => renderer.RendererDirectiveMetadata
renderer.ElementBinder => renderer.RendererElementBinder
impl.Directive => impl.DirectiveMetadata
impl.Component => impl.ComponentMetadata
impl.View => impl.ViewMetadata
Closes#3660
