filestream

A streaming implementation for working with File objects in the browser.


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 video = crel('video', { autoplay: true });
var FileReadStream = require('filestream/read');
var FileWriteStream = require('filestream/write');

function upload(files) {
var queue = [].concat(files);

function sendNext() {
var writer = new FileWriteStream();
var next = queue.shift();

console.log('sending file');
new FileReadStream(next).pipe(writer).on('file', function(file) {
console.log('file created: ', file);
img.src = detect('URL').createObjectURL(file);
// video.src = detect('URL').createObjectURL(next);

if (queue.length > 0) {
sendNext();
}
});
}

sendNext();
}

dnd(document.body, upload);

document.body.appendChild(crel('style', 'body, html { margin: 0; width: 100%; height: 100% }'));
document.body.appendChild(img);
document.body.appendChild(video);

``
