What are common issues with Vue 3 router guards?

Common issues include incorrect guard configurations, asynchronous handling problems, and not properly managing navigation failures.

How can I fix asynchronous handling problems in router guards?

Ensure that your guard functions return a Promise or use async/await to handle asynchronous operations correctly.

What should I do if a guard is not being triggered?

Check if the guard is correctly defined in the route configuration and ensure that the route is being accessed as expected.

Can you give an example of a router guard implementation?

Sure! Here's a simple example:

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