Fast polyfill for TextEncoder and TextDecoder, only supports utf-8
npm install @tensor-hq/fast-text-encoding
This is a fast polyfill for [TextEncoder][1] and [TextDecoder][2], which let you encode and decode JavaScript strings into UTF-8 bytes.
It is fast partially as it does not support^ any encodings aside UTF-8 (and note that natively, only TextDecoder supports alternative encodings anyway).
See some benchmarks.
^If this polyfill used on Node v5.1 through v11 (when Text... was introduced), then this simply wraps Buffer, which supports many encodings and is native code.

Install as "fast-text-encoding" via your favourite package manager.
You only need this polyfill if you're supporting older browsers like IE, legacy Edge, ancient Chrome and Firefox, or Node before v11.
Include the minified code inside a
⚠️ You'll probably want to depend on "text.min.js", as it's compiled to ES5 for older environments.
If your project doesn't need the polyfill, but is included as a transitive dependency, we publish an empty version that you could pin NPM or similar's version algorithm to.
Use "fast-text-encoding@empty".
