This module contains the protobuf definition of the UnixFS data structure found at the root of all UnixFS DAGs.
## Install
The UnixFS spec can be found in the [ipfs/specs repository](http://github.com/ipfs/specs)
```console
$ npm i ipfs-unixfs
```
## Example - Create a file composed of several blocks
### Browser `<script>` tag
Loading this module through a script tag will make it's exports available as `IpfsUnixfs` in the global namespace.
```html

```
## Spec
The UnixFS spec can be found inside the [ipfs/specs repository](http://github.com/ipfs/specs)
### Use in Node.js
```JavaScript
import { UnixFS } from 'ipfs-unixfs'
```
### Use in a browser with browserify, webpack or any other bundler
The code published to npm that gets loaded on require is in fact a ES5 transpiled version with the right shims added. This means that you can require it and use with your favourite bundler without having to adjust asset management process.
