This is a simple application that I have used to try my hand at node.js and redis. The idea came from a co-worker who asked me if I could build an application to collect the votes of our other co-workers to determine where to eat. This is the result.
There is a full tutorial at http://ejosh.co/de/2015/01/node-js-socket-io-and-redis-intermediate-tutorial-server-side/ and a screencast at https://www.youtube.com/watch?v=-_u0NjmSKgI.
I tried to keep this as simple as I could (in both programming and use). There are four things that you can do; enter an area, log in, search, and vote.
- Enter an area.
The area is set by the hash in the URL. Enter #test at the end of the URL and you will have entered the test area. Only votes inside of each area are broadcast and tallied.
- Log in.
No passwords just a name. Enter a name, email, or facebook username into the textbox. Names and emails will use gravatar to create your avatar. Your facebook image is used like so - fb:username. Yes you can impersonate people, so be on your best behavior. - Search.
FourSquare is used to find restaurants around you. If the restaurant you want is not found just enter the name and search again. The x button will clear all the searched for restaurants off the map. - Vote.
Click the icon on the map and then click vote. The votes will be tallied and hopefully you will come to a decision.
The areas and votes expire after two hours. You can vote on a lunch spot and everything is cleared out by supper. This is why I am not too concerned about impersonations as everything has an expiration date.
This system uses many different open source software projects.

Client side Qunit tests are in the jstest folder. It is split into four modules: Josh.Cookie, Josh.Map, Josh.Socket, and React components. Coverage is done with Blanket.js. The tests currently pass in Chrome 20 and Firefox 13. IE 9 is almost there, but you will have a rough time if you use it for this.
Server side mocha test are in the test folder. The repository and Socket.IO code is covered at 90%.
If you want to fork or have pull request please make sure they all pass. If you add anything add a test for it.
