HttpClient is an evolution of the existing Angular HTTP API, which exists alongside of it in a separate package, @angular/common/http. This structure ensures that existing codebases can slowly migrate to the new API. The new API improves significantly on the ergonomics and features of the legacy API. A partial list of new features includes: * Typed, synchronous response body access, including support for JSON body types * JSON is an assumed default and no longer needs to be explicitly parsed * Interceptors allow middleware logic to be inserted into the pipeline * Immutable request/response objects * Progress events for both request upload and response download * Post-request verification & flush based testing framework
