How can I improve the performance of Vue Router guards?

To improve the performance of Vue Router guards, consider using asynchronous guards only when necessary and caching results.

What are some common pitfalls to avoid with router guards?

Common pitfalls include overusing guards, which can lead to performance issues, and not handling asynchronous operations properly.

Can you give an example of an asynchronous guard?

Sure! An asynchronous guard can fetch user permissions from an API before allowing access to a route. Here's a simple example:

router.beforeEach(async (to, from, next) => {
  const hasAccess = await checkUserPermissions();
  if (hasAccess) {
    next();
  } else {
    next('/login');
  }
});
