`ApplicationRef.bootstrap` is supposed to be run inside of `ngDoBootstrap` method
of the module that is bootstrapped, and that method already runs inside of the
zone.
This class allows any provider to know and wait for the initialization of the
application. This functionality previously was tied to `ApplicationRef`.
BREAKING CHANGE:
- `ApplicationRef.waitForAsyncInitializers` is deprecated. Use
`AppInitStatus.donePromise` / `AppInitStatus.done` instead.
If a `@NgModule` has a `bootstrap` property, `PlatformRef.bootstrapModule` /
`PlatformRef.bootstrapModuleFactory` will automatically bootstrap the components
listed in there.
If such a property does not exist, `PlatformRef.bootstrapModule` /
`PlatformRef.bootstrapModuleFactory` will try to call the method `ngDoBootstrap(appRef: ApplicationRef)` on the module class.
Otherwise an error is reported.
Using the `registerBootstrapListener` easily lead to race condition
and needed dependencies on `ApplicationRef`.
BREAKING CHANGE:
- `ApplicationRef.registerBootstrapListener` is deprecated. Provide a multi
provider for the new token `APP_BOOTSTRAP_LISTENER` instead.
Note about the addition of `beforeEach(fakeAsync(inject(…))))` in some tests:
`ApplicationRef` is now using `ngOnDestroy` and there is eager,
including all of its dependencies which contain `NgZone`.
The additional `fakeAsync` in `beforeEach` ensures that `NgZone`
uses the fake async zone as parent, and not the root zone.
BREAKING CHANGE (via deprecations):
- `ApplicationRef.dispose` is deprecated. Destroy the module that was
created during bootstrap instead by calling `NgModuleRef.destroy`.
- `AplicationRef.registerDisposeListener` is deprecated.
Use the `ngOnDestroy` lifecycle hook for providers or
`NgModuleRef.onDestroy` instead.
- `disposePlatform` is deprecated. Use `destroyPlatform` instead.
- `PlatformRef.dipose()` is deprecated. Use `PlatformRef.destroy()`
instead.
- `PlatformRef.registerDisposeListener` is deprecated. Use
`PlatformRef.onDestroy` instead.
- `PlaformRef.diposed` is deprecated. Use `PlatformRef.destroyed`
instead.
This is needed for the case if a `beforeEach` instantiates
`NgZone`and the `it` uses
`TestComponentBuilder.createFakeAsync`.
Otherwise the `NgZone` will use the root zone as parent,
and `TestComponentBuilder.createFakeAsync` will always return
undefined as `tick` does not forward promises created
under the zone of `NgZone`.
This makes `bootstrapModuleFactory` wait for promises
returned by `APP_INITIALIZER`s, also making `bootstrapModuleFactory` async.
I.e. now `bootstrapModule` and `bootstrapModuleFactory` behave in the
same way.
This ensures that all code from module instantiation, to creating
`ApplicationRef`s as well as calling `APP_INITIALIZERS` is run
in the Angular zone.
This also moves the invocation of the initializers from the `ApplicationRef`
constructor into the `bootstrapModuleFactory` call, allowing initializers
to get a hold of `ApplicationRef` (see #9101).
