# Angular Nx Tutorial - Step 4: Connect to an API {% youtube src="https://www.youtube.com/embed/digMpZzPtg8" title="Nx.dev Tutorial | Angular | Step 4: Connect to API" width="100%" /%} Real-world applications do not live in isolation — they need APIs to talk to. Setup your app to talk to an API. **Open `apps/todos/src/app/app.module.ts` to import `HttpClientModule`.** ```typescript import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { HttpClientModule } from '@angular/common/http'; @NgModule({ declarations: [AppComponent], imports: [BrowserModule, HttpClientModule], providers: [], bootstrap: [AppComponent], }) export class AppModule {} ``` **Now, use `HttpClient` in the component to get the data from the api.** ```typescript import { Component } from '@angular/core'; import { HttpClient } from '@angular/common/http'; interface Todo { title: string; } @Component({ selector: 'myorg-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'], }) export class AppComponent { todos: Todo[] = []; constructor(private http: HttpClient) { this.fetch(); } fetch() { this.http.get('/api/todos').subscribe((t) => (this.todos = t)); } addTodo() { this.http.post('/api/addTodo', {}).subscribe(() => { this.fetch(); }); } } ``` ## What's Next - Continue to [Step 5: Add Node Application Implementing an API](/angular-tutorial/05-add-node-app)
