Welcome to React Chess Analysis Board!
React Chess Analysis Board provides a React component you can drop into your React app to render an analysis board of any PGN string.
You can fully customize the style of this analysis board.
Install the library
npm install react-chess-analysis-boardor
yarn add react-chess-analysis-board
Use the component
import ChessPGNAnalysisBoard from 'react-chess-analysis-board' return ( <ChessPGNAnalysisBoard pgnString='[Event "Berlin"] [Site "Berlin GER"] [Date "1852.??.??"] [EventDate "?"] [Round "?"] [Result "1-0"] [White "Adolf Anderssen"] [Black "Jean Dufresne"] [ECO "C52"] [WhiteElo "?"] [BlackElo "?"] [PlyCount "47"] 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bxb4 5.c3 Ba5 6.d4 exd4 7.O-O d3 8.Qb3 Qf6 9.e5 Qg6 10.Re1 Nge7 11.Ba3 b5 12.Qxb5 Rb8 13.Qa4 Bb6 14.Nbd2 Bb7 15.Ne4 Qf5 16.Bxd3 Qh5 17.Nf6+ gxf6 18.exf6 Rg8 19.Rad1 Qxf3 20.Rxe7+ Nxe7 21.Qxd7+ Kxd7 22.Bf5+ Ke8 23.Bd7+ Kf8 24.Bxe7# 1-0' /> )
React Chess Analysis Board accepts the following props:
pgnString[string | required]: any valid PGN
config[object | optional]: an object for various components
getCurrentPosition[function | optional]: calls your callback function, passing a
currentPositionobject as a parameter, which can be used to construct another analysis board you are keeping in sync with this one.
currentPosition** [object | optional]**: sets the entire state of the analysis board. Used, for example, if keeping two analysis boards in sync with one another. You should directly pass the object from a
getCurrentPositioncall from another analysis board you are keeping in sync with this one.
styles[object | optional]: pass strings for each style that correspond to your own css classes to override the default classes used by React Chess Analysis Board.
