Angular 4 – Cannot find name ‘HttpClient’

HttpClient got introduced in Angular 4.3.0 version. Also you have to make sure you have imported & injected HttpClientModule in your main AppModule‘s imports metadata.

// Import HttpClientModule from @angular/common/http in AppModule
import {HttpClientModule} from '@angular/common/http';


//in place where you wanted to use `HttpClient`
import { HttpClient } from '@angular/common/http';
