Lists service requests within the City of Chicago's 311 system that have recently been created, updated or closed. It uses civic data from Chicago's Open311 API.
Features:
- Service requests appear as they're created/updated/closes
- Watch (and listen to) the mayor as he leaps over newly submitted requests and collects boxes when requests are updated/closed
- Background changes depending on day/night

Slim to none. This application uses a non-standard, Chicago-specific query argument, updated_after (e.g. /requests.json?updated_after=<DATETIME>) when querying requeststhat allows the querying service requests by when they were last updated (the official Open311 specification only allows querying by creation date).
You can find more information about non-standard, Chicago-specific API extensions in Chicago's Open311 Documentation.
The front-end application uses Backbone-Boilerplate running on a Node server and uses Socket.io to send new updates from the server.
- Install the packages:
$ npm install - Start the server:
$ node server.js - Visit the webpage:
http://localhost:3000
On startup, the server initially fetches all service requests update in the previous hour. It then checks every 2 minutes for newly updated service requests and emits them to the browser with a 2 minute delay (as well as a little logic to avoid emitting multiple requests at exactly the same instance). So a service request that was updated at 02:46:15 will be emitted to the client at 02:48:15.
- Build the image:
docker build -t codeforamerica/super-mayor . - Run the image:
docker run -p 3000:3000 -it codeforamerica/super-mayor - Build the image on Heroku:
heroku container:push web --app super-mayor - Promote the image:
heroku container:release web --app super-mayor
If you don't want to wait for actual service requests, you can generate fake service requests by starting the server with the command node test/server.mock.js and then visiting http://localhost:3000 (you will still need to wait ~2 minutes for fake requests to start streaming in).
