What are Vue routing guards and how do they work with Vuex?

Vue routing guards are functions that allow you to control access to routes in a Vue application. They can be used to check authentication, permissions, or any condition before navigating to a route. When integrated with Vuex, you can manage the application's state and use it to determine if a user can access a specific route.

Can you give me an example of how to implement a navigation guard with Vuex?

Sure! You can create a global navigation guard in your router configuration. For example:

router.beforeEach((to, from, next) => {
  const isAuthenticated = store.state.isAuthenticated;
  if (to.meta.requiresAuth && !isAuthenticated) {
    next({ name: 'Login' });
  } else {
    next();
  }
});

This checks if the route requires authentication and redirects to the login page if the user is not authenticated.

What if I want to protect multiple routes?

You can add a meta field to each route that requires authentication. For example:

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

The navigation guard will check the requiresAuth property for each route.

Is there a way to handle errors during navigation?

Yes, you can handle errors by using a try-catch block within your navigation guard. If an error occurs, you can redirect the user to an error page or show a notification.
