custom authentication | Astro Lounge | Page 1

Hi @stray halo. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Astro doesn't provide an official authentication solution, but it allows you to integrate with various authentication libraries such as Lucia Auth, Auth.js, and Clerk. You can also find community "auth" integrations in the integrations directory source (https://docs.astro.build/en/guides/authentication/#_top).

To handle authentication with a custom backend, you would typically store the JWT token in a cookie or local storage after successful login. Then, for protected routes, you can check the presence of this token and redirect the user to the login page if it's not present.

Here's a simplified example of how you can handle this in Astro:

// src/pages/profile.astro
---
import { isLoggedIn } from '../utils'; // This is a custom function you'd need to implement

const cookie = Astro.request.headers.get('cookie');

// If the user is not logged in, redirect them to the login page
if (!isLoggedIn(cookie)) {  
  return Astro.redirect('/login');
}
---
<html>
  <!-- Page content here... -->
</html>

In the isLoggedIn function, you would check for the presence of the JWT token in the cookie source (https://docs.astro.build/en/guides/routing/#dynamic-redirects).

Please note that this is a simplified example and doesn't cover all the aspects of authentication. You would also need to handle the login process, token verification, and more. For a more complete example, you can refer to the guides on adding authentication with Firebase or Supabase in the Astro documentation source (https://docs.astro.build/en/guides/authentication/#_top).
