base64-js
=========
`base64-js` does basic base64 encoding/decoding in pure JS.
[](http://travis-ci.org/beatgammit/base64-js)
[](https://ci.testling.com/beatgammit/base64-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.
## install
With [npm](https://npmjs.org) do:
`npm install base64-js`
## methods
`var base64 = require('base64-js')`
`base64` 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
