You'll need to install a few things before you have a working copy of the project.
Install node.js and npm:
Navigate to the cloned repo's directory.
Run the development server:
npm run dev
This will run a server so you can run the game in a browser. It will also start a watch process, so you can change the source and the process will recompile and refresh the browser automatically.
To run the game, open your browser and enter http://localhost:3000 into the address bar.
Build for deployment:
npm run deploy
This will optimize and minimize the compiled bundle.
Big thanks to these great repos:
