How Node.js Makes Network Code More Testable

Introduction Node.js, a server platform built on Chrome’s JavaScript engine, is changing the face of web development. While Node.js itself is fast and scalable, the open source community surrounding Node.js is constantly discovering new ways to make application development more productive. This article will show how Node.js network code can be easier to write automated […]

Realtime Node.js App: Building a Server

This post is the third in a three-part series describing our investigations into scalability for a second screen application we built for PBS. You can read the series introduction here. Being familiar with the stress testing procedure is all well-and-good, but that knowledge won’t really help you unless you have a server to test. In […]

Bocoup & PBS: Building and Scaling a Realtime Node.js Application

This summer, Bocoup worked with Mozilla and PBS to build an open source, real-time web application for the 2012 US Presidential election. When we began, PBS (specifically, the folks at News Hour) had already completed a client-side application called “Map Center“. Map Center enabled users to view US demographic data and experiment with electoral college […]

Introducing Gith – GitHub WebHooks For Node

GitHub offers a great feature called WebHook URLs. You can add a url to take advantage of git’s post-receive hook and get a POST request containing data related to a repository push (e.g., commits, tags, and head-resets). While the data is very detailed and thorough, its complexity and focus on mimicking the git operations make […]

JavaScript: Arduino Programming on Node.js

Today is Tuesday, May 15th 2012. Just over a year ago, I discovered node-serialport by Chris Williams and went immediately to the closest Microcenter and purchased the Getting Started with Arduino kit. Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested […]

Synchronizing HTML5 Slides with Node.js

I gave a talk in February on Advanced jQuery Templates that had an interesting and unique twist. Instead of changing slides using traditional presentation delivery methods such as a clicker or a laptop keyboard, I used my smartphone which made asynchronous calls to a Node.js server. The server then propagated events to all connected viewers, regardless of […]

Test262, Inside-out

Have you ever noticed how easy it can be to overlook small problems in everyday life? Some things start off as imperceptible but slowly intensify over time, and just like the apocryphal frog in boiling water, we acclimate. In pathological cases, we don’t recognize what’s happening until the issue has grown way out of hand. […]

Introducing the Web Platform Contribution Guide

Many people in the web development community, including many of us at Bocoup, were drawn to the web because it appears to be a diverse and inclusive technology platform. But, when we look around the room at who is working on web standards like HTML, CSS and JavaScript, it is mostly a narrow group of […]
