How do I implement protected routes in Vue 3?

To implement protected routes in Vue 3, you can use Vue Router's navigation guards. This allows you to check if a user is authenticated before accessing certain routes.

Can you show me a code example?

Sure! Here's a simple 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 authentication;
  if (to.meta.requiresAuth && !isAuthenticated) {
    next('/login');
  } else {
    next();
  }
});

This code checks if the user is authenticated before allowing access to the dashboard.

What if I want to redirect users after login?

You can use the next function to redirect users after a successful login. For example:

if (isAuthenticated) {
  next({ path: '/dashboard' });
} else {
  next();
}

Are there any libraries that can help with this?

Yes, libraries like vuex for state management and vue-router for routing can help manage authentication and protected routes effectively.
