Mastermind

A game of mastermind, built in Elm.

Where can I play it?

This game is available to play here.

Building it yourself

The toolchain (Elm compiler and elm-format) is installed through npm:

npm install
npm run build            # writes index.html
npm run build:optimized  # writes optimized-index.html
npm run format           # elm-format the sources
npm run format:check     # verify formatting without writing

Elm packages are declared in elm.json; the compiler downloads them into elm-stuff/ on the first build.
