Base64 encoding/decoding in pure JS
npm install base64-jsbase64-js
=========
base64-js does basic base64 encoding/decoding in pure JS.
Many browsers already have base64 encoding/decoding functionality, but it is for text data, not all-purpose binary data.
Sometimes encoding/decoding binary data in the browser is useful, and that is what this module does.
With npm do:
npm install base64-js and var base64js = require('base64-js')
For use in web browsers do:

base64js has three exposed functions, byteLength, toByteArray and fromByteArray, which both take a single argument.
* byteLength - Takes a base64 string and returns length of byte array
* toByteArray - Takes a base64 string and returns a byte array
* fromByteArray - Takes a byte array and returns a base64 string
