Play Live Coding par Nicolas Leroux (@nicolasleroux - Lunatech) Nicolas présentera le framework Play a travers une application très pratique pour le Scala User Group que nous coderons en live. Nous verrons comment nous interfacer avec l'API de meetup.com. Au programme donc: les fondamentaux de Play, JSON deserialisation, Enumeratee, Enumerator et Iteratee pour ajouter un peu de live streaming.

3. Play 2: developing is like having a good lunch

4. Bring simplicity to java development

5. • It's designed by web developers for web developers.
• Type safety everywhere so you can have safe s…
• Better testing capabilities
• DI at compile time and runtime
• Great ecosystem
• Scheduling and asynchronous capabilities
• Abstraction so it is easy to switch components
• Asset compiler so you javascript is also typesafe
• JSON is a first class citizen
• Websockets, Comet, EventSource
• Streams
• So much to tell about him…
• And once you join the club you can’t get out ;)

7. Bring simplicity and modularity to an asynchronous world

8. We are going to see in more details
A basic Play application
Controller and Action
Routes
Views
Reverse routing
Scala code
Iteratee, Enumerator and Enumeratee
Websocket
JSON parsing
WS Library
Javascript code
…
All in 30mn… So not time for tests

9. Before we start:
Actors = Improved thread that reacts to event
Enumerator = producer of data
Iteratee = consumer of data
Enumeratee = Transform data from an enumerator to an iteratee

10. Bring simplicity to a complex world
Demo

11. Confidential
Questions?
That’s all folks!
