HttpBackend — Angular

A final HttpHandler which will dispatch the request via browser HTTP APIs to a backend.

API

abstract class HttpBackend implements HttpHandler {
  abstract handle(req: HttpRequest<any>): Observable<HttpEvent<any>>;
}

Observable<HttpEvent<any>>

@paramreqHttpRequest<any>

@returnsObservable<HttpEvent<any>>

A final HttpHandler which will dispatch the request via browser HTTP APIs to a backend.

Interceptors sit between the HttpClient interface and the HttpBackend.

When injected, HttpBackend dispatches requests directly to the backend, without going through the interceptor chain.
