# filestream | ||
|
||
A streaming implementation for working with File objects in the browser. | ||
|
||
|
||
[![NPM](https://nodei.co/npm/filestream.png)](https://nodei.co/npm/filestream/) | ||
|
||
|
||
## Why | ||
|
||
Because the implementations that I found really didn't cut the mustard :/ | ||
|
||
## Example Usage | ||
|
||
Displayed below is an example that uses simple file drag and drop. Rather | ||
than immediately displaying the file, the file is piped through a read | ||
stream into a write stream and then finally displayed in the browser. | ||
|
||
```js | ||
var crel = require('crel'); | ||
var detect = require('feature/detect'); | ||
var dnd = require('drag-and-drop-files'); | ||
var img = crel('img'); | ||
var FileReadStream = require('filestream/read'); | ||
var FileWriteStream = require('filestream/write'); | ||
|
||
function upload(files) { | ||
var queue = [].concat(files); | ||
|
||
function sendNext() { | ||
var writer = new FileWriteStream(); | ||
|
||
console.log('sending file'); | ||
new FileReadStream(queue.shift()).pipe(writer).on('finish', function() { | ||
console.log('file created: ', writer.file); | ||
img.src = detect('URL').createObjectURL(writer.file); | ||
}); | ||
} | ||
|
||
sendNext(); | ||
} | ||
|
||
dnd(document.body, upload); | ||
|
||
document.body.appendChild(crel('style', 'body, html { margin: 0; width: 100%; height: 100% }')); | ||
document.body.appendChild(img); | ||
``` | ||
