How do I use Axios token interceptors for API requests?

You can use Axios interceptors to add tokens to your API requests. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import axios from 'axios';

const instance = axios.create();

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

export default instance;

This code sets up an interceptor that adds the token to the headers of each request.

What if the token expires?

You can handle token expiration by checking the response status in a response interceptor and refreshing the token if needed.
