to nodejs

var drop = require('drag-and-drop-files')

var concat = require('concat-stream')

var fileReaderStream = require('filereader-stream')

var zlib = require('zlib')

drop(document.body, function(files) {

var first = files[0]

console.log("start gzip " + first.name);

console.time("gzip")

gzip = zlib.createGzip({'level':1})

gunzip = zlib.createGunzip()

datin = fileReaderStream(first)

datin.pipe(gzip)

gzip.pipe(gunzip)

gunzip.setEncoding('utf8')

var count = 0

gunzip.on('data', function(chunk) { count = count + chunk.length; })

gunzip.on('finish', function() { console.log("done, got " + count + " bytes"); console.timeEnd("gzip") })

gunzip.on('close', function() { console.log("closed, got " + count + " bytes"); console.timeEnd("gzip") })

gunzip.on('error',

function(err) {

console.log("error, got " + count + " bytes");

console.log(err.message)

console.log(err.stack)

console.timeEnd("gzip")

})

It's day one for me with javascript and nodejs. I have no idea. I cobbled this together, built with:

browserify -e ./ > try-build.js

and this .html file

<html>

<body>

Drop something on me

</body>

</html>

Crashes similarly in safari and chrome when I drop 4GB file on it. I'd appreciate any suggestions. Here's all I installed:

npm install filereader-stream

npm install drag-and-drop-files

npm install concat-stream
