An ES-spec-compliant shim/polyfill/replacement for ArrayBuffer base64 methods that works as far down as ES3

This package implements the es-shim API “multi” interface. It works in an ES3-supported environment and complies with the spec.

Because the Iterator.prototype methods depend on a receiver (the this value), the main export in each subdirectory takes the string to operate on as the first argument.

The main export of the package itself is simply an array of the available directory names. It’s sole intended use is for build tooling and testing.

If Uint8Array is not present, the shim functions and auto entrypoints will be a no-op.

Supported things

- Uint8Array.fromBase64
- Uint8Array.fromHex
- Uint8Array.prototype.toBase64
- Uint8Array.prototype.toHex
- Uint8Array.prototype.setFromBase64
- Uint8Array.prototype.setFromHex

Getting started

``sh
npm install --save es-arraybuffer-base64
`

Usage/Examples

`js
const fromHex = require('es-arraybuffer-base64/Uint8Array.fromHex');
const toHex = require('es-arraybuffer-base64/Uint8Array.prototype.toHex');
const assert = require('assert');

const array = new Uint8Array([72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100]);
const hex = '48656c6c6f20576f726c64';

assert.deepEqual(fromHex(hex), array);
assert.equal(toHex(array), hex);
`

`js
require('./auto'); // shim all of the methods

require('./Uint8Array.fromHex/auto'); // shim the “fromHex” method
`
