- 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.
Closes#9729
BREAKING CHANGE:
`Type` is now `Type<T>` which means that in most cases you have to
use `Type<any>` in place of `Type`.
We don't expect that any user applications use the `Type` type.
Because
- `Form` is **exported** -- see line 30/31 of
`modules/@angular/forms/src/forms.ts`: i.e., <br>`export {Form} from
'./directives/form_interface'`; and
- Methods of `Form`, which are public, have an
`AbstractFormGroupDirective` parameter;
e.g.,<br>`Form.getFormGroup(dir: AbstractFormGroupDirective):
FormGroup`.
Then it makes sense for `AbstractFormGroupDirective` to be
public/exported too. In any case, if it isn't exported then the **API
docs for `Form` don't get generated properly.**
Closes#9732
BREAKING CHANGE:
We have removed the deprecated form directives from the built-in platform directive list, so apps are not required to package forms with their app. This also makes forms friendly to offline compilation.
Instead, we have exposed three modules:
OLD API:
- `DeprecatedFormsModule`
NEW API:
- `FormsModule`
- `ReactiveFormsModule`
If you provide one of these modules, the default forms directives and providers from that module will be available to you app-wide. Note: You can provide both the `FormsModule` and the `ReactiveFormsModule` together if you like, but they are fully-functional separately.
**Before:**
```ts
import {disableDeprecatedForms, provideForms} from @angular/forms;
bootstrap(App, [
disableDeprecatedForms(),
provideForms()
]);
```
**After:**
```ts
import {DeprecatedFormsModule} from @angular/common;
bootstrap(App, {modules: [DeprecatedFormsModule] });
```
-OR-
```ts
import {FormsModule} from @angular/forms;
bootstrap(App, {modules: [FormsModule] });
```
-OR-
```ts
import {ReactiveFormsModule} from @angular/forms;
bootstrap(App, {modules: [ReactiveFormsModule] });
```
You can also choose not to provide any forms module and run your app without forms.
Or you can choose not to provide any forms module *and* provide form directives at will. This will allow you to use the deprecatedForms API for some components and not others.
```
import {FORM_DIRECTIVES, FORM_PROVIDERS} from @angular/forms;
@Component({
selector: some-comp,
directives: [FORM_DIRECTIVES],
providers: [FORM_PROVIDERS]
})
class SomeComp
```
- ts-api-guardian will now error if a new public symbol is added with a stability marker (`@stable`, `@experimental`, `@deprecated`)
- DomEventsPlugin and KeyEventsPlugin were removed from public api surface - these classes is an implementation detail
- deprecated BROWSER_PROVIDERS was removed completely
- `@angular/compiler` was removed from the ts-api-guardian check since this package shouldn't contain anything that users need to directly import
- the rest of the api surface was conservatively marked as stable or experimental
BREAKING CHANGES: DomEventsPlugin and KeyEventsPlugin previously exported from core are no longer public - these classes are implementation detail.
Previously deprecated BROWSER_PROVIDERS was completely removed from platform-browser.
