Protecting the frontend routes of our application
Protecting the frontend routes of our application
Now that users can sign in to our app, we need to protect the frontend routes of our application. What does this mean? It means that only authenticated users (i.e., users with a valid JWT token) should be allowed to access certain pages. If a user is not authenticated, they should be redirected to the login page, where they can sign in. Additionally, if a user tries to access a protected page but is redirected to log in first, they should be automatically redirected back to the originally requested page after a successful sign-in. In the next lesson, I’ll show you how to implement this functionality in a simple and effective way.
Authentication
Learning Highlights
- 0:45
Understanding why frontend route protection is essential: logged-out users can currently access private pages like dashboard and settings, which should remain restricted to authenticated users only.
- 1:25
Learn how authentication flow redirects users properly: when accessing protected pages while logged out, users are redirected to sign-in and then automatically returned to their originally requested page.
- 2:56
How to implement frontend protection components that validate tokens: these components check if authentication tokens stored in local storage exist and remain valid, as tokens can expire requiring re-authentication.
- 4:26
Mastering redirect URL parameters for seamless user experience: the system stores the requested page URL as a parameter during login, enabling automatic redirection to the settings page (or any protected route) after successful authentication.
