Naming and Versioning

chessboard2 is a distinct project from chessboard.js. The project name is "chessboard2" and the version of the library will be independent of the version of original chessboard.js.

To remove any confusion for users, I will release chessboard2 at v2.0.0 for it's "initial release". There will not be a v1.0.0 major release of chessboard2.

It is possible (although unlikely) that chessboard.js will have a v2.0.0 branch.

Development Setup

Make sure that node.js, yarn, and a modern version of the JVM are installed (for shadow-cljs), then:

## initial setup: install node_modules/ folder
yarn install

## produce website/chessboard2.js and build the local website
npm run build

## run a local web server on port 3232
npm run local-dev

In order to create and publish a release:

## 1) update CHANGELOG
## 2) make sure flags/runtime-checks? is set to false
## 3) update package.json version
## 4) create a git commit
## 5) create git tag: "git tag -a v1.4 -m "my version 1.4" "
## 6) push git tag to GitHub: git push origin <tagname>

## 7) create fresh build
npm run release

## 8) sanity-check the result files
npm publish --dry-run

## 9) publish
npm publish --access=public

Tests

## Unit Tests
npm run test

## Cypress
npm run cypress

TODO before go-live

[ ] variadic removeArrow, removeCircle, removePiece functions
[ ] add "Rings"
- are these separate from Circles or just an added config value?
[ ] custom Items
- add Duck to board, add toaster SVG
[ ] version the position? increment by 1 every time the position changes
[ ] review the speed shorthand times. ie: what should "slow" and "superslow" feel like?

API

getItems() return all items
"pulse" a piece with some simple animations
"bounce" a piece?
animate an arrow
removeArrow(<arrowId>, <arrowId>, etc)
