Yatzy Laboratory is a progressive web app Yahtzee game with a competitive twist. Each game you play is identified by a seed value and the rolls of the dice are generated with a HOTP algorithm using that seed. This seed is accessible as a QR code after you complete a game, which you can screenshot and send to a friend. When your friend loads that QR code, the game they play is the exact same sequence of rolls that you played. When they finish their game you'll be able to compare notes and see who played the sequence the best.
If you're interested in a detailed breakdown of some of the concepts used in this project, I've written some tutorials on CodeREVUE.net that work through a smaller example project.
This project includes a Docker Compose configuration that's used for building and developing this project. You'll need to have Docker Desktop installed to use it, but if you prefer to just use npm directly that should work just fine as well.
# Launch a local server
# See the npm start target
docker-compose up
# Generate a release build
docker-compose run development npm run build
# Cleanup Docker containers
