How do I implement authentication in Vue 3 with Vue Router?

To implement authentication in Vue 3 with Vue Router, you can use navigation guards to protect routes.

Can you show me an example of a navigation guard?

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

router.beforeEach((to, from, next) => {
  const isAuthenticated = // your logic to check if user is authenticated;
  if (to.meta.requiresAuth && !isAuthenticated) {
    next({ name: 'Login' });
  } else {
    next();
  }
});

What if I want to redirect users after login?

You can redirect users by passing a redirect query parameter to the login route and using it after successful login.
