What are the best practices for using Vue Router guards?

When using Vue Router guards, it's important to keep your logic simple, avoid unnecessary complexity, and ensure that guards are reusable.

Can you give me an example of a simple route guard?

Sure! A simple route guard can check if a user is authenticated before allowing access to a route. You can use the beforeEnter guard like this:

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

What should I avoid when implementing route guards?

Avoid using too many nested guards, as they can make your routing logic hard to follow. Also, don't perform heavy computations in guards; keep them lightweight.

How can I test my route guards effectively?

You can test route guards by simulating different user states (authenticated vs. unauthenticated) and checking if the navigation behaves as expected using unit tests.
