#### Convert a Blob to a [Buffer](https://github.com/feross/buffer).

[![Sauce Test Status](https://saucelabs.com/browser-matrix/blob-to-buffer.svg)](https://saucelabs.com/u/blob-to-buffer)

Say you're using the ['buffer'](https://github.com/feross/buffer) module on npm, or
[browserify](http://browserify.org/) and you're working with lots of binary data.

Unfortunately, sometimes the browser or someone else's API gives you a `Blob`. Silly
browser. How do you convert it to a `Buffer`?

Something with a goofy `FileReader` thingy... Time to Google for it yet again... There must be a better way!

***There is! Simply use this module!***

Works in the browser. This module is used by [WebTorrent](http://webtorrent.io)!

### install

```
npm install blob-to-buffer
```

### usage

```js
var toBuffer = require('blob-to-buffer')

// Get a Blob somehow...
var blob = new Blob([ new Uint8Array([1, 2, 3]) ], { type: 'application/octet-binary' })

toBuffer(blob, function (err, buffer) {
  if (err) throw err

  buffer[0] // => 1
  buffer.readUInt8(1) // => 2
})
```
