How to add providers to Injector dynamically?

Question

Each component can specify new Providers using its providers property in ComponentMetadata.

Is there a way to specify provider

Answer 1

I've done it in the bootstrap part.

bootstrap(AppComponent,[
    provide( RequestOptions, { useClass: DefaultRequestOptions } ),
    provide(Http, { useFactory:
        function(backend, defaultOptions) {
            return new Http(backend, defaultOptions); },
        deps: [XHRBackend, RequestOptions]}),
]);

I'm guessing it can be done in a component too:

You make it dynamic by adding decisions into the factory function instead of just returning the same object.
