Install:
npm i compression-streams-polyfill # or yarn add, or pnpm add
Import:
import 'compression-streams-polyfill';
// CompressionStream and DecompressionStream are now available
If your environment doesn't support ES Modules:
require('compression-streams-polyfill');
If you want to load from a CDN in the browser:
<!--
You should use either UNPKG or jsDelivr (i.e. only one of the following)
You can specify the version, e.g. with compression-streams-polyfill@0.1.4
-->
<script src="https://unpkg.com/compression-streams-polyfill"></script>
<script src="https://cdn.jsdelivr.net/npm/compression-streams-polyfill"></script>
This polyfill is almost perfectly spec-compliant. Nonetheless, if you'd like to avoid adding CompressionStream
and DecompressionStream
to the global scope, you can use the ponyfill.
Note that you must supply your own TransformStream
implementation to use the ponyfill (though TransformStream
is available in most modern browsers).
import { makeCompressionStream, makeDecompressionStream } from 'compression-streams-polyfill/ponyfill';
// If you'd like to also ponyfill TransformStream:
// import { TransformStream } from 'web-streams-polyfill/ponyfill';
const CompressionStream = makeCompressionStream(TransformStream);
const DecompressionStream = makeDecompressionStream(TransformStream);
This polyfill is based on fflate and is therefore very fast. It tends to be between 20% slower and 5% faster than Chromium's native CompressionStream
and DecompressionStream
. The CompressionStream
polyfill also yields similar compression ratios to the native implementation.
The polyfill's full bundle size is about 17kB minified, or 7kB gzipped.
