How do I set up authentication with Vue Router and SSR?

To set up authentication with Vue Router and SSR, you need to manage user sessions and protect routes. Start by creating a middleware that checks if a user is authenticated before accessing certain routes.

What kind of middleware should I create?

You can create a simple middleware function that checks for a valid token in the request headers. If the token is missing or invalid, redirect the user to the login page.

Can you show me an example of that middleware?

Sure! Here's a basic example:

function authMiddleware(req, res, next) {
  const token = req.headers['authorization'];
  if (token) {
    // Verify token logic here
    next(); // User is authenticated
  } else {
    res.redirect('/login'); // Redirect to login
  }
}

How do I integrate this middleware with my Vue Router?

You can use the middleware in your server setup. For example, in your Express server, apply the middleware to your routes before rendering the Vue app.
