How do I handle authentication redirects in Vue Router?

To handle authentication redirects in Vue Router, you can use navigation guards. These allow you to check if a user is authenticated before accessing certain routes.

Can you show me an example of how to implement a navigation guard?

Sure! You can define a global beforeEach guard like this:

router.beforeEach((to, from, next) => {
  const isAuthenticated = // your logic to check authentication;
  if (to.meta.requiresAuth && !isAuthenticated) {
    next({ name: 'Login' }); // redirect to login if not authenticated
  } else {
    next(); // proceed to the route
  }
});

What if I want to redirect the user back to their original route after logging in?

You can store the original route in a variable before redirecting to the login page, then use it after successful login to redirect back.

Thanks! Is there a way to protect multiple routes at once?

Yes, you can use route meta fields to specify which routes require authentication and check for those in your navigation guard.
