|
|
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>` |
|
|
|
## methods |
|
|
|
`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 |
