This app can be easily customized for novel formats a tournament might use. If you have feature requests or ideas, you're welcome reach out on our Discord server, Facebook messenger, or on the fediverse.
If you want to take a stab at developing on the app yourself, you will need have node.js >= 18.0.0 installed along with yarn. Some familarity with React will also help.
Clone this repo to your computer. Then the following commands will be useful:
# Before running anything else, do this!
# It's a one-time local install of dependencies needed to build the app.
yarn install
# local development will start, with app running at http://localhost:8080/
# edits to the files in ./src/ will automatically reload the browser
yarn start
# if you make changes to any game/song data in ./src/songs/ this will give
# a basic sanity check on the format and contents of it
yarn validate:json
# build a zipped, standalone copy of the app that runs entirely offline,
# jacket images and all! simply unzip somewhere and open index.html
yarn build:zipThere are some other useful scripts in scripts/ that help in maintaining data integrity and pulling in new song data. Several have top-level aliases so you can conveniently update song data: (must have node and yarn installed, and run yarn install once, as above)
# download latest StepManiaX song data and jackets
yarn import:smx
# download latest DDR A3 song data and jackets (blends data from ZIv, RemyWiki, skillattack)
yarn import:ddr
# import an ITG/StepMania song pack into card draw
yarn import:itg path/to/pack/folder some-stub-name
# import the latest Pump it Up data using a data dump found here:
# https://github.com/AnyhowStep/pump-out-sqlite3-dump/
yarn import:pump path/to/pumpout/db
