| base64-js |
| ========= |
| |
| `base64-js` does basic base64 encoding/decoding in pure JS. |
| |
| [](http://travis-ci.org/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` and `var base64js = require('base64-js')` |
| |
| For use in web browsers do: |
| |
| `<script src="base64js.min.js"></script>` |
