How can I implement OAuth in Angular using guards?

To implement OAuth in Angular using guards, you can create an AuthGuard that checks if the user is authenticated.

What steps do I need to follow to create the AuthGuard?

First, generate the AuthGuard using Angular CLI, then implement the canActivate method to check authentication.

Can you show me a code example for the AuthGuard?

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.isAuthenticated()) {
      return true;
    }
    this.router.navigate(['/login']);
    return false;
  }
}

What about handling token expiration?

You can handle token expiration by checking the token's validity in the AuthGuard and redirecting to the login page if it's expired.
