Web Streams, based on the WHATWG spec reference implementation.
This library comes in four variants:
@mattiasbuelens/web-streams-polyfill: a polyfill that replaces the native stream implementations. Recommended for use in web apps through a<script>tag.@mattiasbuelens/web-streams-polyfill/es6: a polyfill targeting ES2015+ environments. Recommended for use in web apps targeting modern browsers through a<script>tag.@mattiasbuelens/web-streams-polyfill/ponyfill: a ponyfill that provides the stream implementations without replacing any globals. Recommended for use in Node applications or web libraries.@mattiasbuelens/web-streams-polyfill/ponyfill/es6: a ponyfill targeting ES2015+ environments. Recommended for use in modern Node applications, or in web libraries targeting modern browsers.
Each variant also includes the type definitions for WHATWG streams from DefinitelyTyped.
Usage as a polyfill:
<!-- unpkg cdn -->
<script src="https://unpkg.com/@mattiasbuelens/web-streams-polyfill/dist/polyfill.min.js"></script>
<!-- self hosted -->
<script src="/path/to/web-streams-polyfill/dist/polyfill.min.js"></script>
<script>
var readable = new ReadableStream();
</script>Usage as a Node module:
var streams = require("@mattiasbuelens/web-streams-polyfill/ponyfill");
var readable = new streams.ReadableStream();Usage as a ES2015 module:
import { ReadableStream } from "@mattiasbuelens/web-streams-polyfill/ponyfill";
const readable = new ReadableStream();The polyfill and ponyfill variants work in any ES5-compatible environment that has a global Promise.
If you need to support older browsers or Node versions that do not have a native Promise implementation
(check the support table), you must first include a Promise polyfill
(e.g. promise-polyfill).
The polyfill/es6 and ponyfill/es6 variants work in any ES2015-compatible environment.
Thanks to these people for their work on the original polyfill:
