What are the best practices for using router guards in Vue.js?

When using router guards in Vue.js, it's important to keep your guards simple and focused. Avoid complex logic within the guards and instead delegate to services or store actions.

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

Sure! A simple router guard can check if a user is authenticated before allowing access to a route. Here's a basic example:

router.beforeEach((to, from, next) => {
  const isAuthenticated = // logic to check if user is authenticated;
  if (to.meta.requiresAuth && !isAuthenticated) {
    next({ name: 'Login' });
  } else {
    next();
  }
});

What should I avoid when implementing router guards?

Avoid using router guards for heavy computations or API calls, as this can slow down navigation. Instead, handle such logic in components or services.

How can I test my router guards?

You can test your router guards by writing unit tests that simulate navigation and check if the correct routes are accessed based on the guard logic.
