BREAKING CHANGE:
- Platform pipes can only contain types and arrays of types,
but no bindings any more.
- When using transformers, platform pipes need to be specified explicitly
in the pubspec.yaml via the new config option
`platform_pipes`.
- `Compiler.compileInHost` now returns a `HostViewFactoryRef`
- Component view is not yet created when component constructor is called.
-> use `onInit` lifecycle callback to access the view of a component
- `ViewRef#setLocal` has been moved to new type `EmbeddedViewRef`
- `internalView` is gone, use `EmbeddedViewRef.rootNodes` to access
the root nodes of an embedded view
- `renderer.setElementProperty`, `..setElementStyle`, `..setElementAttribute` now
take a native element instead of an ElementRef
- `Renderer` interface now operates on plain native nodes,
instead of `RenderElementRef`s or `RenderViewRef`s
Closes#5993
BREAKING CHANGE:
Previously, pipes that wanted to be notified when they were destroyed
would implement the PipeOnDestroy interface and name the callback
`onDestroy`. This change removes the PipeOnDestroy interface and
instead uses Angular's lifecycle interface `OnDestroy`, with the
`ngOnDestroy` method.
Before:
```
import {Pipe, PipeOnDestroy} from 'angular2/angular2';
@Pipe({pure: false})
export class MyPipe implements PipeOnDestroy {
onDestroy() {}
}
```
After:
import {Pipe, OnDestroy} from 'angular2/angular2';
@Pipe({pure: false})
export class MyPipe implements PipeOnDestroy {
ngOnDestroy() {}
}
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
A quoted expression is:
quoted expression = prefix `:` uninterpretedExpression
prefix = identifier
uninterpretedExpression = arbitrary string
Example: "route:/some/route"
Quoted expressions are parsed into a new AST node type Quote. The `prefix` part of the
node must be a legal identifier. The `uninterpretedExpression` part of the node is an
arbitrary string that Angular does not interpret.
This feature is meant to be used together with template AST transformers introduced in
https://github.com/angular/angular/commit/a43ed79ee7d49ec55a0adea9b587ed67780c870c. The
transformer would interpret the quoted expression and convert it into a standard AST no
longer containing quoted expressions. Angular will continue compiling the resulting AST
normally.
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}'.
- Changes the `alreadyChecked` flag of AbstractChangeDetector to a new `state` flag.
- Changes all checks of alreadyChecked to check that the state is NeverChecked.
- Set state to Errored if an error is thrown during detection.
- Skip change detection for a detector and its children when the state is Errored.
- Add a test to validate this fixes issue #4323.
Closes#4953
- fixes wrapping for object literal keys called `template`.
- spacing in destructuring expressions.
- changes to keep trailing return types of functions closer to their
function declaration.
- better formatting of string literals.
Closes#4828
