What are the best practices for implementing route guards in my application?

When implementing route guards, consider the following best practices: 1. Use canActivate for route protection, 2. Keep guards simple and focused, 3. Handle asynchronous checks gracefully, and 4. Provide user feedback for unauthorized access.

Can you explain how to handle asynchronous checks in route guards?

Certainly! To handle asynchronous checks, you can return a Promise or an Observable from your guard. This allows you to perform tasks like fetching user permissions before allowing access to a route.

What should I do if a user is not authorized to access a route?

If a user is not authorized, you can redirect them to a login page or a dedicated 'access denied' page. It's also helpful to display a message explaining why access was denied.

Are there any common mistakes to avoid when using route guards?

Yes, common mistakes include overcomplicating guards, not handling edge cases, and failing to provide clear user feedback. Keeping guards simple and user-friendly is key.
