What is a route guard in Vue 3?

A route guard in Vue 3 is a way to control access to certain routes in your application, ensuring users meet specific criteria before navigating.

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

Sure! You can use the beforeEnter guard in your route definition. For example:

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

What are the different types of route guards available?

In Vue 3, there are several types of route guards: global guards, per-route guards, and in-component guards. Each serves different purposes for controlling access.

How do I test if my route guard is working?

You can test your route guard by trying to navigate to the protected route while authenticated and unauthenticated to see if it redirects correctly.
