Hex encoding. An extremely fast and synchronous JS implementation.
npm install hex-encodingHex encoding. An extremely fast and synchronous JS implementation.
If you can make this faster without using WASM or async stuff please ping me.
``sh`
npm install hex-encoding
`ts
import Hex from 'hex-encoding';
// Hex encoding & decoding
{
const raw = 'Hello 😃';
const uint8 = new TextEncoder ().encode ( raw );
console.log ( uint8 ); // => Uint8Array(10) [ 72, 101, 108, 108, 111, 32, 240, 159, 152, 131 ]
const encoded = Hex.encode ( uint8 );
console.log ( encoded ); // => '48656c6c6f20f09f9883'
const decoded = Hex.decode ( encoded );
console.log ( decoded ); // => // => Uint8Array(10) [ 72, 101, 108, 108, 111, 32, 240, 159, 152, 131 ]
