How do I set up authentication with routing in Vue 3?

To set up authentication in Vue 3 with routing, you can use Vue Router along with a state management solution like Vuex or the Composition API.

What libraries do I need for this setup?

You will need Vue Router for routing, and you might consider using libraries like Axios for API calls and Vuex for state management.

Can you provide a code example?

Sure! Here's a basic example:

import { createRouter, createWebHistory } from 'vue-router';
import Login from './components/Login.vue';
import Dashboard from './components/Dashboard.vue';

const routes = [
  { path: '/login', component: Login },
  { path: '/dashboard', component: Dashboard, meta: { requiresAuth: true } }
];

const router = createRouter({
  history: createWebHistory(),
  routes
});

router.beforeEach((to, from, next) => {
  const isAuthenticated = false; // Replace with your auth logic
  if (to.meta.requiresAuth && !isAuthenticated) {
    next('/login');
  } else {
    next();
  }
});

export default router;

How do I handle user sessions?

You can handle user sessions by storing the authentication token in local storage or cookies and checking it on route changes.
