v3.0.0-alpha+1

3.0.0-alpha+1

New features

• We now use the formal <T> generic type syntax for methods, not /*<T>*/.

• Re-enabled strong-mode analysis within the project, and fixed some errors.

Breaking changes

• Removed viewBindings from Component. This has been interchangeable with
  viewProviders for a while now.

  BEFORE: dart @Component(viewBindings: const [])

  AFTER: dart @Component(viewProviders: const [])

• Removed EventManager from the public API. Code generation is now closer to
  document.addEventListener and having this interception layer would not
  allow further optimizations.

• Removed IterableDifferFactory and KeyValueDifferFactory from the public
  API. We have planned compiler optimizations that will no longer allow
  overriding our diffing implementations. Looking into alternatives before a
  final 3.0.0 release that are lower cost.

• ASYNC_VALIDATORS can no longer return a Stream instance, only Future.

• The experimental NgTestBed was removed. Use package:angular_test now.

• By default, the ExceptionHandler is a BrowserExceptionHandler, which
  prints exceptions to the console. If you don't want this behavior (i.e.
  releasing to production), make sure to override it.

Bug fixes

• When setting up a new NgControl, valueAccessor no longer can throw an NPE

3.0.0-alpha

3.0.0-alpha

This is the first pre-release of AngularDart 3.0.0. This code is considered
production quality, but additional breaking changes and features are planned
before releasing a final version.

New features

• (Forms) AbstractControl.markAsDirty now emits a status change event.

Breaking changes

• DOM adapter is now completely removed from the API and generated code
• A name parameter is now required for all @Pipe(...) definitions:

BEFORE: dart @Pipe(name: 'uppercase')

AFTER: dart @Pipe('uppercase')

• DomEventsPlugin now requires a strongly typed interface to dart:html.
• Null is no longer propagated as an initial change value. Code should be
  updated to either deliver a different initial value or components with an
  @Input() should have an appropriate default value.

BEFORE

<my-component [value]="null"></my-component>
...
String _value;

set value(String value) {
  _value = value ?? 'Default name';
}

AFTER

String _value = 'Default name';

set value(String value) { _value = value; }

• Removed NgPlural, deprecated as of 2.1.0.
• Removed ObservableListDiffFactory, deprecated as of 2.1.0.
• Event handlers are bound at initialization time. Therefore, the following
  will no longer work, because clickHandler is null during initialization.

@Component(
    selector: 'my-component',
    template: '<div (click)="clickHandler($event)"></div>')
class MyComponent {
  Function clickHandler;
}

• Removed Component.moduleId, which was unused.

Deprecations

• IterableDiffers and KeyValueDiffers are deprecated. The cost of looking
  up to see if a custom differ is available is too high for almost no use.
  Before they're removed, we'll have other customization options.

Bug fixes

• Fixed a bug where the router didn't work on a root path in IE11.
• Fixed generated code that caused a strong-mode warning on AppView<...>.
• Fixed a bug where DDC didn't work properly with "pure" Pipes.
• Some simple types are now propagated to the generated .template.dart file.

Refactors

• Removed NgZoneImpl, all the code exists in NgZone now.
• We now generate specific code for view and content children (faster).
• Projectable nodes now use the visitor pattern in AppView.
• In generated .template.dart change detected primitives are typed.
• Moved renderType as a static class member in generated code.

2.2.0

2.2.0

API changes

• Breaking changes
  • Using @ViewQuery|Children|Content| in a constructor is no longer valid.
    This caused significant extra code to need to be generated for a case that
    is relatively rare. Code can safely be moved into a setter in most cases.

BEFORE

class MyComponent {
  QueryList<ChildComponent> _childComponents;

  MyComponent(@ContentChildren(ChildComponent) this._childComponents);
}

AFTER

class MyComponent {
  QueryList<ChildComponent> _childComponents;

  @ContentChildren(ChildComponent)
  set childComponents(QueryList<ChildComponent> childComponents) {
    _childComponents = childComponents;
  }
}

Bug fixes

• Importing angular2/reflection.dart now works properly.

2.1.1

2.1.1

API changes

• Introduced angular2/reflection.dart as canonical way to opt-in to mirrors.
  In 2.2.0 it will be considered deprecated to enable runtime reflection by
  any other means.
