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
Currently, core depends on DomRenderer, which depends on the browser.
This means that if you depend on angular2/core, you will always
pull in the browser dom adapter and the browser render, regardless
if you need them or not.
This PR moves the browser dom adapter and the browser renderer out of core.
BREAKING CHANGE
If you import browser adapter or dom renderer directly (not via angular2/core),
you will have to change the import path.
Since editors and IDEs do typechecking and show errors in place,
often there is no benefit to running type checking in our test pipeline.
This PR allows you to disable type checking:
gulp test.unit.js --noTypeChecks
This commit also makes es6 generation optional.
fix(build): removes unnecessary circular dependencies
Closes#5299
After discussing it we decided that PLATFORM_ is a better prefix for directives available everywhere in the app.
BREAKING CHANGE
AMBIENT_DIRECTIVES -> PLATFORM_DIRECTIVES
AMBIENT_PIPES -> PLATFORM_PIPES
Closes#5201
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}'.
Ambient directives can be configured when bootstraping an application.
Ambient directives can be used in every component of the application without
needing to explicitly list them.
Refactor EventEmitter and Async Facade to match ES7 Observable semantics, properly use RxJS typedefs, make EventEmitter inherit from RxJS Subject. Closes#4149.
BREAKING CHANGE:
- consumers of EventEmitter no longer need to call .toRx()
- EventEmitter is now generic and requires a type - e.g. `EventEmitter<string>`
- EventEmitter and Observable now use the `.subscribe(generatorOrNext, error, complete)` method instead of `.observer(generator)`
- ObservableWrapper uses `callNext/callError/callComplete` instead of `callNext/callThrow/callReturn`
- 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
This allows TypeScript to produce an API surface which matches the Dart semantics.
I found these with:
gulp build.js.dev && find dist/js/dev/es5/angular2/src -name "*.d.ts" -exec grep -H -n '^ *_' {} \;
Closes#4638
