hex-lite
isomorphic hex library in 256 bytes
Install
npm install hex-lite
Usage
const hex = require('hex-lite')
hex.toUint8Array('000f10ff000f10')
hex.fromUint8Array(new Uint8Array([0,15,16,255,0,15,16]))
hex.toBuffer('000f10ff000f10')
hex.fromBuffer(new Uint8Array([0,15,16,255,0,15,16]).buffer)
Can it be smaller?
If you use ES6 imports with a bundler that supports tree-shaking, yes!
import { fromUint8Array } from 'hex-lite'
I wanna go fast!
The Node implementation is just a proxy to Node's Buffer
object to be as fast as possible. The default browser implementation optimizes for size, so if you're looking for raw speed, import like this:
import hex from 'hex-lite/fast/hex-lite.mjs'
