Node-http-xhr NPM

`node-http-xhr`

An implementation of XMLHttpRequest for node.js using the http.request API.

Motivation

This package was written to provide the XMLHttpRequest API to test browser code that is being tested in a node.js environment.

Installation

npm install --save node-http-xhr

Usage

// Standalone usage
var XMLHttpRequest = require('node-http-xhr');

// Usage as global XHR constructor
global.XMLHttpRequest = require('node-http-xhr');


var req = new XMLHttpRequest();

// Event handlers via .on${event} properties:
req.onreadystatechange = function() {
  console.log('readyState: ' + req.readyState);
};

// or using .addEventListener(event, handler):
req.addEventListener('load', function() {
  console.log('response: ' + req.response);
});

req.open('GET', 'https://github.com/aspyrx', true);
req.send();

Note about browser environments

If you use a bundler like browserify or webpack that follows the browser field in package.json, the module will simply export window.XMLHttpRequest. This is provided for sake of compatibility.

Known issues

Currently, some features are lacking:

Some ProgressAPI events (loadstart, loadend, progress)
responseType values other than '' or 'text' and corresponding parsing
- As a result of the above, overrideMimeType() isn't very useful
setRequestHeader() doesn't check for forbidden headers.
withCredentials is defined as an instance property, but doesn't do anything since there's no use case for CORS-like requests in node.js right now.
