Fetch Ponyfill

WHATWG fetch ponyfill

Ponyfill: A polyfill that doesn't overwrite the native method.

This module wraps the github/fetch polyfill in a CommonJS module for browserification, and avoids appending anything to the window, instead returning a setup function when fetch-ponyfill is required. Inspired by object-assign.

When used in Node, delegates to node-fetch instead.

Usage

var fetch = require('fetch-ponyfill')(options);

where options is an object with the following optional properties:

option	description
Promise	An A+ Promise implementation. Defaults to window.Promise in the browser, and global.Promise in Node.
XMLHttpRequest	The XMLHttpRequest constructor. This is useful to feed in when working with Firefox OS. Defaults to window.XMLHttpRequest. Has no effect in Node.
