angular-di

So... I'm migrating my "old" code that was using the HttpModule and angular2-jwt lib. Before, I could make angular2-jwt work with the following config: export function authHttpServiceFactory( http: Http, options: RequestOptions, myService: MyService) { return new AuthHttp(new AuthConfig({ globalHeaders: [{'Content-Type': 'application/json'}], noJwtError: true, tokenGetter: (() => myService.get('my_token')) }), http, options); } @NgModule({ providers: [ { provide: AuthHttp, useFactory: authHttpServiceFactory, deps: [Http, RequestOptions, MyService] } ] }) export class AuthModule {} ... But now,

A framework-agnostic way of phrasing this question is "How to register another service with the service locator?" The Injector is set up to be immutable, both the interface and the implementation. interface Injector { abstract get(token: any, notFoundValue?: any): any; } interface https://github.com/angular/angular/blob/master/packages/core/src/di/injector.ts implementation https://github.com/angular/angular/blob/master/packages/core/src/di/reflective_injector.ts How do you add another provider (dynamically, not via a module)? How does Angular do this itself when it is loading new modules

As you all know we have different strategies for providers: useClass , useExisting , useFactory , useValue . But what if I would like to add own strategy? Something like: providers: [ { MyService: MyService, useAsyncFactory: MyAsyncFactory} ] What is the best way to extend ReflectiveInjector and make Angular use your extended variant? I found the place where it's defined, but still looking for a way to overwrite existing Angular DI mechanism. P.S.: Please don't ask why I need it and why not to use existing strategies. I'm doing research about Angular DI and the answer will help me to
