How can I handle errors in Vue.js router guards?

You can handle errors in Vue.js router guards by using try-catch blocks or by returning a promise that rejects.

Can you give me an example of using a try-catch block?

Sure! In your beforeEnter guard, you can wrap your logic in a try-catch like this:

beforeEnter: async (to, from, next) => {
  try {
    // Your logic here
    next(); // Proceed to the route
  } catch (error) {
    console.error(error);
    next('/error'); // Redirect to an error page
  }
}

What if I want to handle specific error types?

You can check the error type in the catch block and handle it accordingly. For example:

catch (error) {
  if (error instanceof SomeSpecificError) {
    next('/specific-error');
  } else {
    next('/generic-error');
  }
}

Is there a way to log errors for monitoring?

Yes, you can log errors to an external service like Sentry or LogRocket in the catch block before redirecting.
