Storm/Finagle Hackathon Submission - Poursquare

This was my submission to the Storm/Finagle Hackathon which took place at hack/reduce in July of 2013.

This repo contains the code for the client portion of the application. This includes the web application that connects to a MongoDB database and a Spring MVC application that displays some statistics and real time checkin map.

Getting Started

Prerequisites

Install the Java SDK and Maven.

Install an application server. I used Tomcat but Jetty or Glassfish or any servlet container will work just fine.

Although I am using Scala, the libraries get bundled into the WAR file, you can deploy it just as you would any other WAR file.

Installing

First, clone the repo onto your local machine.

Next, if you are using Eclipse, you can set up a Dynamic Web Project and have Eclipse automatically publish to the server. If you are using the command line, or just prefer to build a WAR and then deploy it yourself, you can call mvn package and copy the WAR out of the target directory

Running

Start your app server. You'll also want to run the Storm topology so that it can populate Mongo.
Then you can point your browser here to see the most recent checkins:

http://localhost:8080/poursquare/latest

Also check out checkins by countries:

http://localhost:8080/poursquare/countries

And of course, the real time map:

http://localhost:8080/poursquare/map           

Notes

• Implementing Spring MVC in Scala ain't pretty, but it works. It was the fastest way for me to write a small web app. Scalatra might be have been a better fit here.
• I used the Java MongoDB driver and JSON queries. Again, not pretty but it's simple and works just fine. There is a Scala driver called Casbah that may have been a better fit.
