How do I set up routing guards in Vue.js?

To set up routing guards in Vue.js, you can use the beforeEach method in your router configuration. This allows you to define logic that runs before a route is entered.

Can you give me an example of how to implement a simple authentication guard?

Sure! Here's a basic example:

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

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

What if I want to add a loading spinner while the guard checks?

You can manage a loading state in your component or Vuex store. Set the loading state to true before the guard checks and false after. You can then show a spinner based on this state.

Thanks! Is there a way to handle multiple guards?

Yes, you can define multiple guards by chaining them in the beforeEach method or by using route-specific guards in the route definitions.
