The backend is a Java Dropwizard server. The files are in the standard Gradle Java layout, with production files in src/main/java. Assets are served from src/main/resources/assets. The in-game communications are JSON-serialized messages sent to and received from clients via websocket using the Atmosphere framework.

Run either ./gradlew eclipse or ./gradlew idea to setup the project in Eclipse or IntelliJ (respectively), and then run the entry point, TractorServer.java.

The frontend is a single-page React app in plain Javascript. The assets live in client/assets, self-contained React components live in client/components, library code (no React) live in client/lib, and the top-level view components live in client/views.

To start the dev server, run:

npm install
npm run start

Then go to http://localhost:3000. The site will auto-refresh after making any frontend changes.
