This is a simple app that umpires a 2-person rock-paper-scissors games, and also provides a way to see historical results.

Note that the setup and build scripts depend on the yarn package manager (an npm replacement). See the yarn installation guide if you don't already have yarn installed on your computer.

To set up all of the modules (i.e., yarn install, yarn link, yarn run compile, and yarn run compile-test), run ./setup.sh

To run all of the tests, run ./build.sh. Make sure you've first run ./setup.sh. Note that the UI components are tested via a Chrome karma runner, so you'll need to install Chrome if you don't already have it on your computer.

The rps module contains the high level policy (two use cases: play, and history). It also defines a contract for promise-based round repositories. The use cases use the observer pattern to invert the dependency on the UI.

This module exports a contract for the frontend. All frontend implementations conform to the contract.
