Cloud Foundry Twitter Search

This is a distributed application containing 2 components:

  • twitter2rabbit: A standalone Spring Integration application that periodically polls twitter for tweets containing the word "cloud" and places them in a Rabbit queue.
  • rabbit2socks: A node.js application that consumes tweets from the Rabbit queue and pushes them to the browser using Sock.js

Usage

rabbit2socks

Prior to deploying the app, update the file public/index.html to the URL you plan to provide for the application:

var sock = new SockJS("http://mytwittersearch.cloudfoundry.com/socks");

Package the application dependencies by running 'npm install'. To deploy the application to Cloud Foundry, simply use the provided manifest.yml file. You need only to provide the application with a name and URL (make sure you use the URL you specified in public/index.html):

cd rabbit2socks
npm install
vmc push
Would you like to deploy from the current directory? [Yn]:
Application Name: mytwittersearch
Application Deployed URL [mytwittersearch.cloudfoundry.com]:

Open a browser and navigate to http://mytwittersearch.cloudfoundry.com. The page will be blank initially, but watch for dynamically added tweets once you've deployed twitter2rabbit.

twitter2rabbit

Simply use the provided manifest.yml file to deploy the application to Cloud Foundry. You need only to provide the application with a name.

cd twitter2rabbit
mvn package
vmc push
Would you like to deploy from the current directory? [Yn]:
Application Name: twitter2rabbit

Now just keep an eye on http://mytwittersearch.cloudfoundry.com and watch those new tweets pop up every 5 seconds!

Using Gradle

If you would prefer to use Gradle to build twitter2rabbit, simply run "gradle installApp". Then update the path and command in the manifest.yml file:

applications:
  build/install/twitter2rabbit:
...
command: bin/twitter2rabbit
