The project aims at building a small but complete client / server application using very powerfull scala tools to construct fully typed and reactive Web applications. Among them:

• scalajs
• scalatra
• scalatags
• scala.rx
• autowire
• boopickle

as well as scaladget to draw some svg and display a http://d3js.org/-like workflow.

It is an empty ready-to-work application, dealing with all the starting wiring. This prototype also exposes as example a small Graph editor inspired from http://bl.ocks.org/cjrd/6863459 javascript example, but written witten in a reactive way thanks to the scala.rx library.

First, build the javascript:

$ cd scalaWUI
$ sbt
> go // Build the client JS files and move them to the right place

Then, start the server:

> jetty:start // Start the server

Open http://localhost:8080/ in your browser.

The demo provides with a small graph based on d3.js library but with no D3 at all. It only relies on the previously cited libraries. Try to :

• drag the nodes to move them
• shift-click on graph to create a node
• shift-click on a node and then drag to another node to connect them with a directed edge
• click on node or edge and press delete to delete
