Talk #1

hapi – Building apps and services in Node.js

Frederic Hemberger (@fhemberger)

hapi is a framework for building web applications, services and RESTful APIs in Node.js. Besides being the core building block for Walmart's mobile platform, it also powers the new npm website and many others.

Frederic gives a short introduction and explains the core concepts and different approaches compared to other frameworks.

Talk #2

Effective jQuery

Jörn Zaefferer (@bassistance)

In this talk I'll cover several patterns for maintainability and performance, giving some new perspectives on the library we all seem to know so well.

Topics include: how to use event delegation for just in time initialization; how to structure your markup, CSS and JS for them to work well together while promoting maintainability of all three; how to avoid performance bottlenecks when using jQuery; how to use CSS3 transitions with fallbacks; and finally, how to reuse existing widgets with unique look and feel.


After the talks, stick around, have a drink and a chat or two. A great opportunity to get to know fellow JavaScripters.
