TypeScript compiler will now build to ES2015 code and modules. Babili is used to minify ES2015
code, providing an initial optimization that we couldn't previously get just from Uglify. Uses
Babel to convert ES2015 to UMD/ES5 code, and Uglify to minimize the output.
- Introduce `InjectionToken<T>` which is a parameterized and type-safe
version of `OpaqueToken`.
DEPRECATION:
- `OpaqueToken` is now deprecated, use `InjectionToken<T>` instead.
- `Injector.get(token: any, notFoundValue?: any): any` is now deprecated
use the same method which is now overloaded as
`Injector.get<T>(token: Type<T>|InjectionToken<T>, notFoundValue?: T): T;`.
Migration
- Replace `OpaqueToken` with `InjectionToken<?>` and parameterize it.
- Migrate your code to only use `Type<?>` or `InjectionToken<?>` as
injection tokens. Using other tokens will not be supported in the
future.
BREAKING CHANGE:
- Because `injector.get()` is now parameterize it is possible that code
which used to work no longer type checks. Example would be if one
injects `Foo` but configures it as `{provide: Foo, useClass: MockFoo}`.
The injection instance will be that of `MockFoo` but the type will be
`Foo` instead of `any` as in the past. This means that it was possible
to call a method on `MockFoo` in the past which now will fail type
check. See this example:
```
class Foo {}
class MockFoo extends Foo {
setupMock();
}
var PROVIDERS = [
{provide: Foo, useClass: MockFoo}
];
...
function myTest(injector: Injector) {
var foo = injector.get(Foo);
// This line used to work since `foo` used to be `any` before this
// change, it will now be `Foo`, and `Foo` does not have `setUpMock()`.
// The fix is to downcast: `injector.get(Foo) as MockFoo`.
foo.setUpMock();
}
```
PR Close#13785
* feat(forms): ngSubmit event exposes $event from original submit event as local variable
Modify NgForm directive and FormGroup directive to expose the original submit event as $event in the ngSubmit event. Modify docs to reflect changes.
This resolves#10920.
* refactor: code cleanup
BREAKING CHANGE:
The deprecated `provideForms()` and `disableDeprecatedForms()` functions have been removed. Please import the `FormsModule` or the `ReactiveFormsModule` from @angular/forms instead.
BREAKING CHANGE:
The deprecated forms APIs in @angular/common have been removed. Please update to the new forms API in @angular/forms. See angular.io for more information.
