These wrappers are not natively understood by
ts2dart. Removing them will improve Dart2JS
compilation due to fewer megamorphic calls to List
functions.
It also makes Angular code more succinct and
improves type safety in Angular due to better type
inference of the Array component type.
This change exposed several bugs in Angular.
In 'angular2/di' the symbol:
- Inject is a decorator
- InjectAnnotation is an annotation
Internally one an get a hold of annotations without *Annotations appened
(to make ts2dart work without workarounds) by importing from
'angular2/src/di/annotations_impl' instead of 'angular2/di'. This is
needed only for users that transpile through TS and through ts2dart.
BREAKING CHANGE:
Previously, `Directive` was the abstract base class of several directives.
Now, `Directive` is the former `Decorator`, and `Component` inherits from it.
The app is writen in ES6 and transpiles to ES5 and dart as part of the
usual build.
The app contains a component, a directive and a services wired together
through dependency injection.
Before Each:
- gulp build
For es5:
- gulp serve
- open 'localhost:8000/js/examples/lib/hello_world/'
For dart:
- gulp examples/pub.serve
- open 'localhost:8080'
