# hex-lite [](https://npmjs.com/package/hex-lite) [](https://travis-ci.org/kevlened/hex-lite)
isomorphic hex library in 256 bytes
## Install
`npm install hex-lite`
## Usage
```javascript
const hex = require('hex-lite')
hex.toUint8Array('000f10ff000f10')
// new Uint8Array([0,15,16,255,0,15,16])
hex.fromUint8Array(new Uint8Array([0,15,16,255,0,15,16]))
// '000f10ff000f10'
hex.toBuffer('000f10ff000f10')
// ArrayBuffer
hex.fromBuffer(new Uint8Array([0,15,16,255,0,15,16]).buffer)
// '000f10ff000f10'
```
## Can it be smaller?
If you use ES6 imports with a bundler that supports tree-shaking, yes!
```javascript
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:
```javascript
import hex from 'hex-lite/fast/hex-lite.mjs'
```
