How do I implement navigation guards in Vue Router?

You can implement navigation guards in Vue Router by using the beforeEach method. This allows you to define logic that runs before each route change.

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

Sure! Here's a basic example:

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

What does next() do in this context?

The next() function is used to control the navigation. Calling next() allows the navigation to proceed, while passing an argument to next() can redirect to a different route.

Can I use navigation guards for route-specific logic?

Yes, you can define route-specific guards by adding them directly in the route definitions using the beforeEnter property.
