How do I implement authentication in Angular CLI?

To implement authentication in Angular CLI, you can use Angular's built-in services along with a backend API. Would you like a step-by-step guide?

Yes, please provide the steps.

1. Set up your Angular project using Angular CLI. 2. Create a service for authentication. 3. Use HttpClient to communicate with your backend. 4. Implement login and logout methods. 5. Protect routes using guards.

What kind of backend should I use?

You can use any backend technology like Node.js, Django, or ASP.NET. It should provide RESTful APIs for authentication.

Can you show me an example of the authentication service?

Sure! Here's a simple example of an authentication service in Angular:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable({ providedIn: 'root' })
export class AuthService {
  private apiUrl = 'https://yourapi.com/auth';

  constructor(private http: HttpClient) {}

  login(credentials: any): Observable<any> {
    return this.http.post(`${this.apiUrl}/login`, credentials);
  }

  logout(): void {
    // Implement logout logic
  }
}
