XMLHttpRequest module not defined/found

XMLHttpRequest is a built-in object in web browsers.

It is not distributed with Node. The http module is the built-in tool for making HTTP requests from Node.

Most people making HTTP requests from node use a third party library with a friendlier API. Two popular choices are Axios (for use both in Node.js and browsers) and node-fetch (which implements the fetch API which is built into browsers and is a modern replacement for XMLhttpRequest.

If you really want to use XHR in Node.js then there are a couple of third party implementations. xmlhttprequest (which seems to be unmaintained) and xhr2 (which has had an update this year).

  1. Install it with npm, npm install xhr2
  2. Now you can require it in your code. var XMLHttpRequest = require('xhr2'); var xhr = new XMLHttpRequest();
