OpenSnap is a sample reactive application based on:

• Java 8, Spring Framework 4, Spring Boot and asynchronous MongoDB driver on serverside
• Dart and AngularDart on client side

STOMP messages over websocket are used for 2 ways communication between client and server.

Slides of my Devoxx and MixIT talk "Reactive applications with Spring
, AngularDart and Websocket" based on OpenSnap are available on SpeakerDeck.

You can also try the demo (only Chrome supported for now).

How to run it ?

Prerequisites:

• Java 8
• Gradle
• Dart 1.2+
• $PATH should contains dart/dart-sdk/bin and gradle/bin

Build and run OpenSnap:

• git clone https://github.com/sdeleuze/opensnap.git
• ./gradlew build run
• Open the following URL in your browser: http://127.0.0.1:8080/index.html
  • For Dart version, run Dartium browser (/chromium/Chromium)
  • For Javascript version, run your usual browser (only Chrome supported for now)

Notes:

• Make sure that Chrome does not run at the same time than Dartium, since it could prevent the webcam to work

How to contribute ?

Feel free to send pull requests !

My reference development environment is IntelliJ IDEA 13.1 + its Dart plugin. You should :

• import OpenSnap as a Gradle project
• Open OpenSnap module settings and set Java project level to Java 8
• Enable Dart on opensnap-client module (Preferences -> Dart -> Enable Dart for this project + check opensnap-client module).
• Ensure that working directory is set to the absolute path of opensnap/opensnap-server and not only opensnap in run application property.

To run server side, just run or debug Application class main method. For client side, be sure to use http://127.0.0.1:8080 URL in order to avoid cross domain issues
