Next Meetup: Tuesday, December, 9th 2014 — 
New location at triAGENS

Join us at 19:00, talks start at 19:30

We need your participation for Cologne.js: Help us running the meetup!

Talk #1


Sebastian Cohnen (@tisba)

I'd like to talk about time series data(bases) in general and InfluxDB in particular. Since InfluxDB has a HTTP-based API and talks JSON, we can use it directly from Browsers/JavaScript to track events, logs, … or to query data back out e.g. for visualization.

Talk #2

Fullstack JavaScript

Yunus Uyargil, Sebastian Tilch

One team – one language

Building a multiplatform solution with a small team can be a real challenge. To avoid Babylonian confusion, we decided to only use one language for our entire platform, including webapp, backend and mobile app. We would like to share our motivation, experiences and challenges with you.


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