A dead simple full-stack multiplayer game starter using babylon.js for the client and Express and websockets for the server.
There is no server-side validation of anything - the backend simply records player positions and sends them along to other clients. Of course, this could be expanded, and I do intend to work on this more.
Based off of @RaananW's babylonjs-webpack-es6 template.
To run:
$ cd client
$ npm run start
Just a simple Express server built with socket.io.
To run:
$ cd client
$ npm run start
