feat(router): deprecate loadChildren:string (#30073) The proposed ES dynamic import() is now supported by the Angular CLI and the larger toolchain. This renders the `loadChildren: string` API largely redundant, as import() is far more natural, is less error-prone, and is standards compliant. This commit deprecates the `string` form of `loadChildren` in favor of dynamic import(). DEPRECATION: When defining lazy-loaded route, Angular previously offered two options for configuring the module to be loaded, both via the `loadChildren` parameter of the route. Most Angular developers are familiar withthe `string` form of this API. For example, the following route definition configures Angular to load a `LazyModule` NgModule from `lazy-route/lazy.module.ts`: ``` [{ path: 'lazy', loadChildren: 'lazy-route/lazy.module#LazyModule', }] ``` This "magic string" configuration was previously necessary as there was no dynamic module loading standard on the web. This has changed with the pending standardization of dynamic `import()` expressions, which are now supported in the Angular CLI and in web tooling in general. `import()` offers a more natural and robust solution to dynamic module loading. The above example can be rewritten to use dynamic `import()`: ``` [{ path: 'lazy', loadChildren: () => import('./lazy-route/lazy.module').then(mod => mod.LazyModule), }] ``` This form of lazy loading offers significant advantages in terms of: * type checking via TypeScript * simplicity of generated code * future potential to run natively in supporting browsers (see: [caniuse: dynamic import()](https://caniuse.com/#feat=es6-module-dynamic-import)) As a result, Angular is deprecating the `loadChildren: string` syntax in favor of ES dynamic `import()`. An automatic migration will run during `ng upgrade` to convert your existing Angular code to the new syntax. PR Close #30073

feat(router): introduce `ParamMap` to access parameters The Router use the type `Params` for all of: - position parameters, - matrix parameters, - query parameters. `Params` is defined as follow `type Params = {[key: string]: any}` Because parameters can either have single or multiple values, the type should actually be `type Params = {[key: string]: string | string[]}`. The client code often assumes that parameters have single values, as in the following exemple: ``` class MyComponent { sessionId: Observable<string>; constructor(private route: ActivatedRoute) {} ngOnInit() { this.sessionId = this.route .queryParams .map(params => params['session_id'] || 'None'); } } ``` The problem here is that `params['session_id']` could be `string` or `string[]` but the error is not caught at build time because of the `any` type. Fixing the type as describe above would break the build because `sessionId` would becomes an `Observable<string | string[]>`. However the client code knows if it expects a single or multiple values. By using the new `ParamMap` interface the user code can decide when it needs a single value (calling `ParamMap.get(): string`) or multiple values (calling `ParamMap.getAll(): string[]`). The above exemple should be rewritten as: ``` class MyComponent { sessionId: Observable<string>; constructor(private route: ActivatedRoute) {} ngOnInit() { this.sessionId = this.route .queryParamMap .map(paramMap => paramMap.get('session_id') || 'None'); } } ``` Added APIs: - `interface ParamMap`, - `ActivatedRoute.paramMap: ParamMap`, - `ActivatedRoute.queryParamMap: ParamMap`, - `ActivatedRouteSnapshot.paramMap: ParamMap`, - `ActivatedRouteSnapshot.queryParamMap: ParamMap`, - `UrlSegment.parameterMap: ParamMap`

feat(core): Add type information to injector.get() (#13785) - 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
