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.
