How do I implement authentication in my Angular app?

To implement authentication in Angular, you can use services like Auth0 or Firebase, or create your own authentication service.

What are the steps to create my own authentication service?

First, create a user model, then set up a login form, and finally, implement a service to handle authentication logic.

How do I protect routes in Angular after authentication?

You can use route guards to protect routes. Implement CanActivate to check if the user is authenticated before allowing access.

Can you show me an example of a route guard?

Sure! Here's a simple example:

import { Injectable } from '@angular/core';
import { CanActivate, Router } from '@angular/router';
import { AuthService } from './auth.service';

@Injectable({ providedIn: 'root' })
export class AuthGuard implements CanActivate {
  constructor(private authService: AuthService, private router: Router) {}

  canActivate(): boolean {
    if (this.authService.isLoggedIn()) {
      return true;
    }
    this.router.navigate(['/login']);
    return false;
  }
}
