This is a prototype web interface for the Lean 4 version of the Natural Number Game (NNG) of Kevin Buzzard and Mohammad Pedramfar. See the NNG4 repository for more information.
Building this requires a npm toolchain. After cloning the repository you should run
npm install to pull in all dependencies. Then you want to modify the line of src/App.js which defines
the socketUrl variable (there will be a more convenient procedure at some point). For install you can use
localhost there to play locally.
In order to build the website, run npm run build. Then copy the content of the newly created build folder to some place where your webserver can find it. For quick experimentation (and for development) you can run npm start that will perform a non-optimized build and then run a local webserver on port 3000.
