What is an Angular Auth Guard and how do I use it?
An Angular Auth Guard is a service that can control access to routes in your Angular application. It helps protect routes from unauthorized access.
How do I implement an Auth Guard in my Angular app?
To implement an Auth Guard, you need to create a service that implements the CanActivate interface and then add it to your route configuration.
Can you show me a code example of an Auth Guard?
Sure! Here's a simple example:
import { Injectable } from '@angular/core';
import { CanActivate, Router } from '@angular/router';
@Injectable({ providedIn: 'root' })
export class AuthGuard implements CanActivate {
constructor(private router: Router) {}
canActivate(): boolean {
const isAuthenticated = // your logic here;
if (!isAuthenticated) {
this.router.navigate(['/login']);
return false;
}
return true;
}
}
What other types of guards are available in Angular?
In addition to Auth Guards, Angular provides CanDeactivate, Resolve, and CanLoad guards, each serving different purposes for route management.
