Chess Diagram React Component
LIVE DEMO: http://chessdiagram.juddn.com updated 24-apr-2017
Knight's Tour Demo: http://knightstour.juddn.com
NPM: https://www.npmjs.com/package/react-chessdiagram
A react component that can display chess positions from FEN strings, PGN Strings, or a form of algebraic notation (P@a5 R@h8 etc)
It is almost entirely stateless. (some state is maintained to keep track of mouse / touch events, and an internal list of moves when displaying a game)
A callback facility is provided to report dragged pieces back to the host application.
