Based on a fork of\n[chess.js](https://github.com/jhlywa/chess.js), it extends the original with\npowerful multi-game PGN file parsing capabilities while maintaining full\nbackward compatibility.\n\n## โœจ Features\n\n- โ™Ÿ๏ธ **Complete Chess Rules** - Move generation, validation,\n check/checkmate/stalemate detection\n- ๐Ÿ“ **PGN Support** - Parse and generate Portable Game Notation\n- ๐ŸŽฏ **Multi-Game Parsing** - Efficiently handle large PGN files with\n cursor-based iteration\n- โšก **Worker Thread Support** - Parallel parsing for 3-5x performance boost on\n large files\n- ๐Ÿ” **Position Analysis** - Attack detection, piece finding, board queries\n- ๐Ÿ“š **Rich API** - Both legacy (`ChessPGN`) and modern (`Game`) interfaces\n- ๐ŸŽจ **TypeScript First** - Full type safety with comprehensive type definitions\n- โœ… **Well Tested** - 500+ tests with high code coverage\n- ๐Ÿ“– **Extensive Documentation** - Detailed guides and API reference\n\n## ๐Ÿ“ฆ Installation\n\n```bash\nnpm install @chess-pgn/chess-pgn\n```\n\n## ๐Ÿš€ Quick Start\n\n### โ™ป๏ธ Drop-in Replacement for chess.js\n\n**chessPGN** is a drop-in replacement for\n[chess.js](https://github.com/jhlywa/chess.js). Simply swap the import:\n\n```typescript\n// import { Chess } from 'chess.js'\nimport { ChessPGN as Chess } from '@chess-pgn/chess-pgn'\n```\n\nThe ChessPGN class implements the same API as chess.js, so existing code works\nwithout further changes. You gain multi-game PGN parsing, worker thread support,\nand TypeScript-first types โ€” with no rewrites required.\n\n### Basic Game\n\n```typescript\nimport { ChessPGN } from '@chess-pgn/chess-pgn'\n\nconst chess = new ChessPGN()\n\n// Make some moves\nchess.move('e4')\nchess.move('e5')\nchess.move('Nf3')\nchess.move('Nc6')\n\n// Get current position\nconsole.log(chess.fen())\n// rnbqkbnr/pppp1ppp/2n5/4p3/4P3/5N2/PPPP1PPP/RNBQKB1R w KQkq - 2 3\n\n// Check game state\nconsole.log(chess.isCheck()) // false\nconsole.log(chess.isCheckmate()) // false\n\n// Get legal moves\nconsole.log(chess.moves())\n// ['a3', 'a4', 'b3', 'b4', 'c3', 'c4', 'd3', 'd4', ...]\n\n// Export as PGN\nconsole.log(chess.pgn())\n// 1. e4 e5 2. Nf3 Nc6\n```\n\n### Random Game\n\n```typescript\nimport { ChessPGN } from '@chess-pgn/chess-pgn'\n\nconst chess = new ChessPGN()\n\nwhile (!chess.isGameOver()) {\n const moves = chess.moves()\n const move = moves[Math.floor(Math.random() * moves.length)]\n chess.move(move)\n}\n\nconsole.log(chess.pgn())\n```\n\n### Load and Parse PGN\n\n```typescript\nimport { ChessPGN } from '@chess-pgn/chess-pgn'\n\nconst pgn = `[Event \"Casual Game\"]\n[Site \"New York\"]\n[Date \"2025.01.15\"]\n[White \"Alice\"]\n[Black \"Bob\"]\n[Result \"1-0\"]\n\n1. e4 e5 2. Nf3 Nc6 3. Bb5 1-0`\n\nconst chess = new ChessPGN()\nchess.loadPgn(pgn)\n\nconsole.log(chess.getHeaders())\n// { Event: 'Casual Game', Site: 'New York', ... }\n\nconsole.log(chess.history())\n// ['e4', 'e5', 'Nf3', 'Nc6', 'Bb5']\n```\n\n### Multi-Game PGN Files\n\nEfficiently parse large PGN files with multiple games:\n\n```typescript\nimport { indexPgnGames } from '@chess-pgn/chess-pgn'\nimport * as fs from 'fs'\n\nconst pgnContent = fs.readFileSync('games.pgn', 'utf8')\n\n// Create cursor with worker threads for parallel parsing\nconst cursor = indexPgnGames(pgnContent, {\n workers: 4,\n workerBatchSize: 10,\n onError: (err, idx) => console.error(`Game ${idx}: ${err.message}`),\n})\n\n// Iterate through games\nfor await (const game of cursor) {\n const headers = game.getHeaders()\n console.log(`${headers.White} vs ${headers.Black}: ${headers.Result}`)\n\n // Analyze final position\n if (game.isCheckmate()) {\n console.log('Checkmate!')\n }\n}\n\n// Clean up worker threads\nawait cursor.terminate()\n```\n\n### Position Analysis\n\n```typescript\nimport { ChessPGN } from '@chess-pgn/chess-pgn'\n\nconst chess = new ChessPGN()\nchess.move('e4')\nchess.move('e5')\nchess.move('Nf3')\n\n// Check if square is attacked\nconsole.log(chess.isAttacked('e5', 'w')) // true (knight attacks e5)\n\n// Get all attackers of a square\nconsole.log(chess.attackers('e5'))\n// ['f3']\n\n// Find pieces\nconsole.log(chess.findPiece({ type: 'n', color: 'w' }))\n// ['b1', 'f3']\n\n// Get piece at square\nconsole.log(chess.get('f3'))\n// { type: 'n', color: 'w' }\n```\n\n### Verbose Move Details\n\n```typescript\nimport { ChessPGN } from '@chess-pgn/chess-pgn'\n\nconst chess = new ChessPGN()\nchess.move('e4')\nchess.move('e5')\nchess.move('Nf3')\n\n// Get detailed move history\nconst history = chess.history({ verbose: true })\nconsole.log(history)\n/*\n[\n {\n color: 'w',\n from: 'e2',\n to: 'e4',\n piece: 'p',\n san: 'e4',\n before: 'rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1',\n after: 'rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq e3 0 1'\n },\n ...\n]\n*/\n```\n\n### Comments and Annotations\n\n```typescript\nimport { ChessPGN } from '@chess-pgn/chess-pgn'\n\nconst chess = new ChessPGN()\n\nchess.move('e4')\nchess.setComment('The most popular opening move')\nchess.setSuffixAnnotation('!!') // Brilliant move\n\nchess.move('e5')\nchess.setComment('Symmetric response')\nchess.setSuffixAnnotation('!') // Good move\n\n// Get all comments\nconst comments = chess.getComments()\nconsole.log(comments)\n/*\n[\n {\n fen: 'rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq e3 0 1',\n comment: 'The most popular opening move',\n suffixAnnotation: '!!'\n },\n ...\n]\n*/\n\n// Export with comments\nconsole.log(chess.pgn())\n// 1. e4!! {The most popular opening move} e5! {Symmetric response}\n```\n\n## ๐ŸŽ“ API Overview\n\n### Core Classes\n\n- **`ChessPGN`** - Legacy wrapper class with full chess functionality\n- **`Game`** - Modern core implementation (can be used directly)\n- **`Move`** - Rich move object with detailed information\n\n### Common Methods\n\n#### Position Manipulation\n\n- `load(fen)` - Load position from FEN notation\n- `reset()` - Reset to starting position\n- `clear()` - Clear the board\n- `fen()` - Get FEN string of current position\n\n#### Making Moves\n\n- `move(move)` - Make a move (SAN string or object)\n- `moves()` - Get all legal moves\n- `undo()` - Undo last move\n- `history()` - Get move history\n\n#### Game State\n\n- `isCheck()` - Check if in check\n- `isCheckmate()` - Check if checkmate\n- `isStalemate()` - Check if stalemate\n- `isDraw()` - Check if drawn position\n- `isGameOver()` - Check if game is over\n- `turn()` - Get side to move\n\n#### Position Queries\n\n- `get(square)` - Get piece at square\n- `board()` - Get 2D board array\n- `ascii()` - Get ASCII board representation\n- `attackers(square)` - Get pieces attacking a square\n- `isAttacked(square, color)` - Check if square is attacked\n\n#### PGN Operations\n\n- `pgn()` - Export game as PGN string\n- `loadPgn(pgn)` - Load game from PGN\n- `setHeader(key, value)` - Set PGN header\n- `getHeaders()` - Get all headers\n\n#### Comments and Annotations\n\n- `setComment(comment)` - Add comment to position\n- `getComment()` - Get comment for position\n- `getComments()` - Get all comments\n- `setSuffixAnnotation(suffix)` - Add move annotation (!!, !, ?, etc.)\n\n### Multi-Game API\n\n- **`indexPgnGames(pgn, options)`** - Create cursor for multi-game PGN files\n\nOptions:\n\n- `workers` - Enable parallel parsing with worker threads\n- `workerBatchSize` - Games per batch (default: 10)\n- `strict` - Strict PGN parsing mode\n- `onError` - Error callback for malformed games\n\n## ๐Ÿ“š Documentation\n\n- **[Full API Documentation](https://jeffml.github.io/chessPGN/)** - Complete\n API reference\n- **[Advanced Features](./ADVANCED_FEATURES.md)** - Multi-game parsing, worker\n threads, cursor API\n- **[Contributing Guide](./CONTRIBUTING.md)** - How to contribute to the project\n\n## ๐Ÿ—๏ธ Architecture\n\nchessPGN uses a **delegation pattern** where `ChessPGN` wraps the core `Game`\nclass:\n\n- **`Game`** - Core chess logic, single source of truth\n- **`ChessPGN`** - Legacy wrapper, delegates to `Game`\n- **`IChessGame`** - Common interface for both classes\n\nBoth classes implement the same interface and produce identical results,\nverified through extensive parity testing across 469 real games.\n\n## ๐Ÿ”ง Development\n\n```bash\n# Install dependencies\nnpm install\n\n# Run tests\nnpm test\n\n# Run all checks (format, lint, test, build)\nnpm run check\n\n# Build the project\nnpm run build\n\n# Format code\nnpm run format\n```\n\n## ๐Ÿงช Testing\n\nchessPGN has comprehensive test coverage:\n\n- โœ… 527+ tests covering all functionality\n- โœ… Unit tests for individual features\n- โœ… Integration tests for real-world scenarios\n- โœ… Parity tests ensuring `ChessPGN` โ‰ก `Game`\n- โœ… Perft tests for move generation correctness\n\n## ๐Ÿ“Š Browser and Node.js Support\n\n- **Node.js**: 20.x, 22.x, 24.x\n- **Browsers**: All modern browsers (Chrome, Firefox, Safari, Edge)\n- **TypeScript**: Full type definitions included\n\n## ๐Ÿค Contributing\n\nContributions are welcome!
