How can I use Axios interceptors in my Vue application?

You can use Axios interceptors to intercept requests or responses before they are handled by then or catch. This is useful for adding headers, logging, or handling errors globally.

Can you show me a code example?

Sure! Here's a simple example:

import axios from 'axios';

const instance = axios.create();

instance.interceptors.request.use(config => {
    // Modify request config
    config.headers['Authorization'] = 'Bearer token';
    return config;
}, error => {
    return Promise.reject(error);
});

instance.interceptors.response.use(response => {
    // Handle response data
    return response;
}, error => {
    console.error('Error response:', error);
    return Promise.reject(error);
});

What if I want to handle errors globally?

You can handle errors in the response interceptor. For example, you can log the error or show a notification to the user. Just modify the response interceptor to include your error handling logic.
