Talk #1

Professionelle AngularJS-Anwendungen mit TypeScript

Roman Roelofsen (@romanroe)

AngularJS ist eines der beliebtesten Frameworks, um komplexe Rich-Client Anwendungen umzusetzen. Im Vergleich zu klassischen Web-Anwendungen wird dafür deutlich mehr Code für Anwendungs- und Fachlogik mit JavaScript entwickelt und im Browser ausgeführt. Für viele Programmierer bedeutet dies ein Umdenken, besonders wenn bisher mit statisch typisierten Sprachen wie Java oder C# gearbeitet wurde. Die Sprache TypeScript verspricht nun, die Vorteile und Prinzipien beider Welten zu kombinieren: Einerseits ist TypeScript statisch typisiert, andererseits werden die bekannten Muster und Modul-Konzepte der JavaScript-Welt geschickt aufgegriffen. Dieser Vortrag zeigt, wie TypeScript für die Entwicklung von AngularJS (Version 1.x & 2.0) Anwendungen genutzt werden kann, welche Vorteile sich daraus ergeben und wie die typischen Probleme vermieden werden können.

Talk #2

How to develop and structure a react-native app

Christoph Jerolimov (@jerolimov)

[German talk] React is a JS library from Facebook for buildung interfaces, introducted 2013 and currently one of the most famous libraries on GitHub and the web. This spring they also published react-native which allow us to develop mobile apps with JavaScript. - Hybrid apps? Again? But react-native differs from Cordova and other existing Hybrid solutions. It generates native UI elements and tries to create an better/smoother UX than webview or hybrid solutions. On the otherside it also attempts to improve the native developer experience (called DX) with live-reloading etc. This talk gives an introduction into react-native. How to start a small project, create a view hierarchy and show how to split an app into multiple screens.


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