Welcome to React Chess Analysis Board!

[!WARNING] This project is not currently maintained and far from feature-complete. I hope to come back and finish it one day. For now, feel free to use it as inspiration and/or fork it! I will review any pull requests if you'd like to make one.

Description

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.

For a deeper understanding of how the library works, check out this article.

Usage

Getting Started

1. Install the library npm install react-chess-analysis-board or yarn add react-chess-analysis-board

2. Set up styles. Copy and paste the entire file src/style.scss to get started with default styles. Make these CSS classes available to the component in your project that will use react-chess-analysis-board. This gets you started with the default styles, which you can iterate on.

3. Use the component

import ChessAnalysisBoard from 'react-chess-analysis-board'

return (
	<ChessAnalysisBoard
		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"]

API

React Chess Analysis Board accepts the following props:

• pgnString [string | required]: any valid PGN
• config [object | optional]: an object for various components
  • boardConfig [object | optional]: an object for configs related to the board
    • fen [string | optional]: a fen string to indicate the initial position of the board for analysis
    • ChessBoardProps [object | optional]: props that are passed directly to React-Chessboard, used for styling the board.
• getAnalysisPosition [function | optional]: calls your callback function, passing a analysisPosition object as a parameter, which can be used to construct another analysis board you are keeping in sync with this one.
• analysisPosition** [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 getAnalysisPosition call from another analysis board you are keeping in sync with this one.

Styling

React-chess-analysis-board looks for specific RCAB- prefixed classNames you can use in your source code.

If you create css classes with any of the classNames found in src/lib/style.css and make them available to the ChessAnalysisBoard component, they will be applied. We recommend copying src/lib/styles.css into your own css file, and then iterating on the styling from there.

Features

Current

• Full React Analysis Board component
• Subcomponents can be accessed individually (BoardHeader, Board, Panel, and Moves)
• Managed state for unlimited branches of analysis
  • Traverse state with panel buttons or arrow keys
  • Create an alternative branch by exploring new moves
  • Access any board state on any branch by clicking on the move
• PGN-viewer functionality
• Style with your own css classes

Planned

• Ability to show chess engine notation from a connected engine
• Stronger control over styles and layout, especially around Moves component
• Handling pawn promotion in side lines outside the root PGN (planned inclusion in react-chessboard) and will then be handled in this library

• If it materially changes the experience of using the library, is a major new feature, or is something you think someone else might already be working on, please open an issue for discussion before contributing, or confirm that you're working on it within the discussion on an existing issue.
• Unsure what to contribute? Check out the existing issues for inspiration.

Opening a PR

1. Fork this repository
2. Clone your forked repository onto your development machine git clone https://github.com/yourUsernameHere/react-chess-analysis-board.git cd react-chess-analysis-board
3. Create a branch for your PR git checkout -b your-branch-name
4. Set upstream remote git remote add upstream https://github.com/ps2-controller/react-chess-analysis-board.git
5. Make your changes -- the lib folder contains the library with index.tsx as the entry point, and App.tsx imports and uses the library to make local development easy. Use npm run dev to run App.tsx in your browser.
6. Push your changes git add . git commit -m "feature/cool-new-feature" git push --set-upstream origin your-branch-name
7. Create pull request on GitHub
8. Contribute again git checkout main git pull upstream main git checkout -b your-new-branch-name
