How do I handle authentication errors in Vue.js?

You can handle authentication errors in Vue.js by using a centralized error handling mechanism, such as interceptors in Axios.

Can you show me an example of using Axios interceptors?

Sure! You can set up an Axios interceptor like this:

axios.interceptors.response.use(response => {
  return response;
}, error => {
  if (error.response.status === 401) {
    // Handle unauthorized access
    alert('Unauthorized! Please log in again.');
  }
  return Promise.reject(error);
});

What if I want to redirect the user to the login page?

You can use Vue Router to redirect the user. Inside the interceptor, you can do:

if (error.response.status === 401) {
  router.push('/login');
}
