How to Use Fetch in Node JS?

Fetch is a way to programmatically make HTTP requests in JavaScript. It's similar to XHR and XMLHttpRequest but is designed to work better with Promises. We'll discuss here how fetch can enhance the development experience when it comes time to ask for data from an API.

//Plain text or HTML
fetch('https://github.com/').then(res => res.text()).then(body => console.log(body));

//JSON
fetch('https://api.github.com/users/github')
    .then(res => res.json())
    .then(json => console.log(json));

//Simple Post
fetch('https://httpbin.org/post', { method: 'POST', body: 'a=1' })
    .then(res => res.json()) // expecting a json response
    .then(json => console.log(json));

//Post with JSON
const body = { a: 1 };
 
fetch('https://httpbin.org/post', {
        method: 'post',
        body:    JSON.stringify(body),
        headers: { 'Content-Type': 'application/json' },
    })
    .then(res => res.json())
    .then(json => console.log(json));
//Post with form parameters

const { URLSearchParams } = require('url');
 
const params = new URLSearchParams();
params.append('a', 1);
 
fetch('https://httpbin.org/post', { method: 'POST', body: params })
    .then(res => res.json())
    .then(json => console.log(json));

The Fetch API is used to asynchronously request resources (such as files) over the network. It's part of the ES6 standard and supported by all major browsers.
