How do I set up route guards in Vue.js using Vue Router?

To set up route guards in Vue.js, you can use the beforeEnter navigation guard in your route definitions.

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

Sure! You can define a route like this:

const routes = [
  {
    path: '/protected',
    component: ProtectedComponent,
    beforeEnter: (to, from, next) => {
      const isAuthenticated = // your logic to check authentication;
      if (isAuthenticated) {
        next();
      } else {
        next('/login');
      }
    }
  }
];

What if I want to use multiple guards for a single route?

You can chain multiple guards by defining them in an array. Each guard can call next() to proceed or redirect.

Are there any built-in guards in Vue Router?

Yes, Vue Router provides built-in guards like beforeEach, beforeResolve, and afterEach for global navigation control.
