How do I handle authentication redirects in Vue 3?

In Vue 3, you can handle authentication redirects using navigation guards in your router. Would you like a code example?

Yes, please provide a code example.

Sure! You can use the beforeEach guard in your router setup. Here's a basic example:

const router = createRouter({
  history: createWebHistory(),
  routes: [
    { path: '/login', component: Login },
    { path: '/dashboard', component: Dashboard, meta: { requiresAuth: true } },
  ],
});

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

This will redirect users to the login page if they try to access a route that requires authentication.

What if I want to redirect them back to their original page after login?

You can achieve that by storing the original route in a variable before redirecting to the login page. After successful login, you can redirect them back to that stored route.
