Pong reinvented using Rails and Vue.js

This purpose of this app was to demonstrate the use of a progressive JavaScript framework Vue.js and Rails ActionCable to build a two player pong game that can be played over the web.

There also exists a GamesChannel which broadcasts every time a point is scored or a game changes state.

There exists a latency issue where a paddle's position may be behind to it's true position at a point in time. This may also exist with the ball's position as seen by the client. I'm sure this is a common issue among multiplayer games, but have no experience in that department so am open to suggestions.

# run the migration
rake db:migrate

# dev server
rails server

# install dependencies
npm install

# serve with hot reload at localhost:8080
npm run dev

The app is deployed to heroku using a nodejs buildpack and ruby buildpack. A configuartion in package.json for "heroku-postbuild" which runs npm run build before starting the Rails server.
