This is a little demo app which I made to make myself more familiar with:

• spray (spray.io)
• Akka (akka.io)
• Apache Camel (camel.apache.org)
• Backbone.js (backbonejs.org)
• Bootstrap (getbootstrap.com)
• RequireJS (requirejs.org)

What does this application? It just shows some historical stockdata from stock-symbols you can enter. Right now the stockdata is just stored in a simple HashMap. The saved quotedata is served as a json-document by spray-can.

To start the app just start SBT (scala-sbt.org) in root folder of application and then start the application with re-start command. This starts spray-can on the given port in src/main/resources/application.conf. Here you also can specify the startdate and the enddate for the historical data to be retrieved from the internet.

Further improvements:

• add a durable storage engine (e.g. RDBMS, NOSQL, Cassandra)
• improve/clean REST-API on backend and frontend
• cleanup some stuff in Backbone.js frontend
• add more functionality
