Compatible with any binary data and every modern JS engine.

```js

import {encode, decode} from 'uint8-to-base64';

// const {encode, decode} = require('uint8-to-base64');

const utf8Binary = new Uint8Array(anyArrayBuffer);

// encode converts Uint8Array instances to base64 strings

const encoded = encode(utf8Binary);

// it's just like any other string

console.log(encoded);

// decode converts base64 strings, encoded via this module,

// into their original Uint8Array representation

const decoded = decode(encoded);

console.assert(

  JSON.stringify([...utf8Binary]) ===

  JSON.stringify([...decoded]),

  'safe Uint8Array to utf-16 conversion'

);

```

**Please note** this module requires global `atob` and `btoa` in NodeJS **< 16**, polyfilled in old tests in here as such.

```js

global.btoa = str => Buffer.from(str).toString('base64');

global.atob = str => Buffer.from(str, 'base64').toString();

```

Looking for a drop in module that converts into utf-16 strings instead? Check [uint8-to-utf16](https://github.com/WebReflection/uint8-to-utf16#readme) out!
