How do I implement authentication in Vue Router?

To implement authentication in Vue Router, you can use navigation guards to protect routes. You can check if a user is authenticated before allowing access to certain routes.

Can you show me an example of a navigation guard?

Sure! Here's a simple example:

const router = new VueRouter({
  routes: [
    { path: '/protected', component: ProtectedComponent, meta: { requiresAuth: true } },
    // other routes
  ]
});

router.beforeEach((to, from, next) => {
  if (to.matched.some(record => record.meta.requiresAuth) && !isAuthenticated()) {
    next({ path: '/login' });
  } else {
    next();
  }
});

What is the isAuthenticated function supposed to do?

The isAuthenticated function should return a boolean indicating whether the user is logged in or not. You can implement it based on your authentication logic, such as checking a token in local storage.

How can I manage user sessions in Vue?

You can manage user sessions by storing authentication tokens in local storage or cookies and checking them on app load to determine if the user is logged in.
