With the coming bootstrapping changes, a single application (and thus Router) can have multiple root components. One of these needs to be identified as the "primary" component from which the Router will load its configuration. This is now done by providing a ROUTER_PRIMARY_COMPONENT binding to the primary component type.
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
BREAKING CHANGE:
Instead of configuring pipes via a Pipes object, now you can configure them by providing the pipes property to the View decorator.
@Pipe({
name: 'double'
})
class DoublePipe {
transform(value, args) { return value * 2; }
}
@View({
template: '{{ 10 | double}}'
pipes: [DoublePipe]
})
class CustomComponent {}
Closes#3572
BREAKING CHANGES:
- `ShadowDomStrategy` was removed. To specify the encapsulation of a component use `@View(encapsulation: ViewEncapsulation.NONE | ViewEncapsulation.EMULATED | ViewEncapsulation.NATIVE)`
- The default encapsulation strategy is now `ViewEncapsulation.EMULATED` if a component contains styles and `ViewEncapsulation.NONE` if it does not. Before this was always `NONE`.
- `ViewLoader` now returns the template as a string and the styles as a separate array
BREAKING CHANGES:
Dart applications and TypeScript applications meant to transpile to Dart must now
import `package:angular2/bootstrap.dart` instead of `package:angular2/angular2.dart`
in their bootstrap code. `package:angular2/angular2.dart` no longer export the
bootstrap function. The transformer rewrites imports of `bootstrap.dart` and calls
to `bootstrap` to `bootstrap_static.dart` and `bootstrapStatic` respectively.
