How do I implement navigation guards in Vue 3?

In Vue 3, you can implement navigation guards using the beforeEach, beforeEnter, and afterEach hooks in your router configuration.

Can you give me an example of using beforeEach?

Sure! Here's a simple 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 redirects the user.

Can I use multiple guards?

Yes, you can use multiple guards. They will be called in the order they are defined, and you can chain them together.
