The app is meant to take an informal straw poll for an upcoming parliamentary election. It was written in four hours as part of a coding exercise for mySociety.
- The app first asks if the user will vote in the upcoming election, and what constituency they vote in.
- If the user answers yes, then it asks who they will vote for. It then takes them to the results page.
- If the user answers no, it takes them straight to the results page.
- The results page shows two doughnut graphs with results for both the constituency and national contexts.
The app is written using the Express web application framework, so you will need the following to run it:
- NodeJS v0.8.14
- Express v3.1.0
- Jade 0.28.2
- A server capable of running nodeJS.
- A browser that supports HTML5.
I’ve included a copy of Express and Jade in the node_modules directory.
I am using the open source Chart.js graphing library, which I’ve included in public/javascripts.
To run the app, make sure node is in your PATH and type ‘node app.js’.
Point your browser (I recommend Chrome) to ‘http://localhost:3000’ to play with the app. Currently, you can vote multiple times by going back to this main page.
- The app currently stores the data in memory to simplify everything. Implement a way to persist the data to a file from time to time, or use some sort of database as the data store (maybe Redis).
- The parties, constituencies and polling objects currently are explicitly defined. Generate them programmatically, perhaps from text files.
- Leave a cookie on the user’s browser to prevent them from voting multiple times.
- Currently using HTML5 specific features and tested only in Chrome. Do cross-browser testing and support older browsers.
- Make the site responsive so that it appears reasonable when accessed from a mobile phone.
- Make site accessible.
- Tweak theming…
