How do I implement authentication with Axios?

To implement authentication with Axios, you can set up interceptors to attach tokens to your requests.

Can you show me an example of how to set up an interceptor?

Sure! You can use axios.interceptors.request.use to add the token to the headers like this:

axios.interceptors.request.use(config => {
  const token = localStorage.getItem('token');
  if (token) {
    config.headers['Authorization'] = `Bearer ${token}`;
  }
  return config;
});

What if the token expires?

If the token expires, you should handle the 401 response by redirecting the user to the login page or refreshing the token.
