How can I use Axios for advanced HTTP requests in Node.js?

You can use Axios to make advanced HTTP requests by utilizing features like interceptors, cancellation tokens, and custom instances. Would you like to see an example?

Yes, please provide an example of using interceptors.

Sure! You can set up an interceptor like this:

const axios = require('axios');

const instance = axios.create();

instance.interceptors.request.use(config => {
    console.log('Request:', config);
    return config;
});

instance.get('https://api.example.com/data');

This will log the request configuration before sending it.

What about handling errors with Axios?

You can handle errors using a .catch() block or by using interceptors for responses. Here's an example:

instance.get('https://api.example.com/data')
    .then(response => console.log(response.data))
    .catch(error => console.error('Error:', error));

This will log any errors that occur during the request.

Can I cancel a request in Axios?

Yes, you can cancel a request using a cancellation token. Here's how:

const CancelToken = axios.CancelToken;
let cancel;

axios.get('https://api.example.com/data', {
    cancelToken: new CancelToken(function executor(c) {
        cancel = c;
    })
}).catch(function (thrown) {
    if (axios.isCancel(thrown)) {
        console.log('Request canceled', thrown.message);
    } else {
        // handle error
    }
});

// To cancel the request
cancel('Operation canceled by the user.');
