VanJS is back! Join us Thursday March 30th for talks on Javascript Debugging and WebRTC.

Doors at 6:40pm, with talks beginning at 7pm.

1. Here Be Dragons - Javascript Debugging: Rami Sayar (, Microsoft

Have you ever cried yourself to sleep, unable to find the cause of a horrendous bug in your Node app? Cry no more, your tears will be reshaped as blinding swords as we explore uncharted territories laced with mystical creatures.

JavaScript debugging is an often-avoided topic due to the uncertainty of how best to accomplish it and the lack of powerful introspective tools. This talk will explore new territory and showcase tools that help you debug complex and difficult issues in your node or frontend app. Libraries and tools such as node-debugger, Visual Studio Code, vorlon.js, nGrok will be used to slay dragons. No more shall you fear building complex apps with JavaScript!

2. An introduction to WebRTC: Adam van den Hoven, Frozen Mountain (

It’s easy enough to pick up any WebRTC library and quickly connect two people face-to-face in the browser. Building useful applications requires an understanding of how WebRTC works to avoid common pitfalls. In this presentation we'll look at some of the details of networks, negotiation and control and how that affects decisions you make when building a WebRTC application. We will also look at incorporating WebRTC into native and mobile systems and why you might want to do that.
