After the introduction of the view engine, we can drop a lot of code that is not used any more.
This should reduce the size of the app bundles because a lot of this code was not being properly tree-shaken by today's tools even though it was dead code.
- 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();
}
```

BREAKING CHANGE:
Exceptions are no longer part of the public API. We don't expect that anyone should be referring to the Exception types.
ExceptionHandler.call(exception: any, stackTrace?: any, reason?: string): void;
change to:
ErrorHandler.handleError(error: any): void;
BREAKING CHANGE: previously deprecated @Component.directives and @Component.pipes support was removed.
All the components and pipes now must be declarated via an NgModule. NgModule is the basic
compilation block passed into the Angular compiler via Compiler#compileModuleSync or #compileModuleAsync.
Because of this change, the Compiler#compileComponentAsync and #compileComponentSync were removed as well -
any code doing compilation should compile module instead using the apis mentioned above.
Lastly, since modules are the basic compilation unit, the ngUpgrade module was modified to always require
an NgModule to be passed into the UpgradeAdapter's constructor - previously this was optional.
BREAKING CHANGE: previously deprecated coreBootstrap and coreLoadAndBootstrap have been removed.
Please follow deprecation instructions to migrate your code.
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.
We changed the bootstrap order:
1. create NgZone
2. bootstrap ng1 inside NgZone and upgrade ng1 components to ng2 components.
3. bootstrap ng2 with NgZone
Note: Previous footgun behavior was: bootstrap ng2 first to extract NgZone, so that ng1 bootstrap can happen in NgZone. This meant that if ng2 bootstrap eagerly compiled a component which contained ng1 components, then we did not have complete metadata.
BREAKING CHANGE:
- `ApplicationRef.run` is deprecated. Use `NgZone.run` directly
- `ApplicationRef.injector` is deprecated. Inject an `Injector` or
use `NgModuleRef.injector` instead
- `ApplicationRef.zone` is deprecated. Inject `NgZone` instead.
`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 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).
Fixes#9101Fixes#10363Fixes#10205
BREAKING CHANGES:
- `browserPlatform`/`browserDynamicPlatform`/... have been deprecated and renamed into `platformBrowser`/`platformBrowserDynamic`/....
- `bootstrapModule` and `bootstrapModuleFactory` have been moved to be members of `PlaformRef`.
E.g. `platformBrowserDynamic().bootstrapModule(MyModule)`.
This contains major changes to the compiler, bootstrap of the platforms
and test environment initialization.

BREAKING CHANGE:
- Semantics and name of `@AppModule` (now `@NgModule`) changed quite a bit.
This is actually not breaking as `@AppModules` were not part of rc.4.
We will have detailed docs on `@NgModule` separately.
- `coreLoadAndBootstrap` and `coreBootstrap` can't be used any more (without migration support).
Use `bootstrapModule` / `bootstrapModuleFactory` instead.
- All Components listed in routes have to be part of the `declarations` of an NgModule.
Either directly on the bootstrap module / lazy loaded module, or in an NgModule imported by them.
BREAKING CHANGE (deprecations)
- Instead of `coreBootstrap`, create an `@AppModule` and use `bootstrapModule`.
- Instead of `coreLoadAndBootstarp`, create an `@AppModule` and use `bootstrapModuleFactory`.
- Instead of `bootstrapWorkerApp`, create an `@AppModule` that includes the `WorkerAppModule` and use `bootstrapModule` with the `workerAppPlatform()`.
- Instead of `bootstrapWorkerUi`, create an @AppModule that includes the `WorkerUiModule` and use `bootstrapModule` with the `workerUiPlatform()` instead.
- Instead of `serverBootstrap`, create an @AppModule and use `bootstrapModule` with the `serverDynamicPlatform()` instead.
- Instead of `PLATFORM_PIPES` and `PLATFORM_DIRECTIVES`, provide platform directives/pipes via an `@AppModule`.
- Instead of `ComponentResolver`:
- use `ComponentFactoryResolver` together with `@AppModule.precompile`/`@Component.precompile` or `ANALYZE_FOR_PRECOMPILE` provider for dynamic component creation.
- use `AppModuleFactoryLoader` for lazy loading.
- Instead of `SystemJsComponentResolver`, create an `@AppModule` and use `SystemJsAppModuleLoader`.
- Instead of `SystemJsCmpFactoryResolver`, create an `@AppModule` and use `SystemJsAppModuleFactoryLoader`
