File upload in Node.js to an Express server, using streams
// node: v0.10.21
// request: 2.27.0
var request = require('request');
var fs = require('fs');
var r = request.post("http://server.com:3000/");
// See http://nodejs.org/api/stream.html#stream_new_stream_readable_options
// for more information about the highWaterMark
// Basically, this will make the stream emit smaller chunks of data (ie. more precise upload state)
var upload = fs.createReadStream('f.jpg', { highWaterMark: 500 });

How to set up Gulp for Compass compilation and minification, JavaScript minification, livereloading, and use with ExpressionEngine.

How to set up Gulp with an ExpressionEngine project

I freaking love working with technologies like Grunt and Gulp, and wanted to share how to get my current EE front-end workflow set up. With a few tweaks, this can also be used with virtually any other sites (I've used it with Laravel, static sites, Craft, etc).

Install Node.js

  • If Node is not yet installed on the machine, it will need to be installed

Install Gulp (if needed)
