See +[chessboard.js - Random vs Random](http://chessboardjs.com/examples#5002) for an +example. + +## Parsers (permissive / strict) + +This library includes two parsers (`permissive` and `strict`) which are used to +parse different forms of chess move notation. The `permissive` parser (the +default) is able to handle many non-standard derivatives of algebraic notation +(e.g. `Nf3`, `g1f3`, `g1-f3`, `Ng1f3`, `Ng1-f3`, `Ng1xf3`). The `strict` parser +only accepts moves in Standard Algebraic Notation and requires that they +strictly adhere to the specification. The `strict` parser runs slightly faster +but will not parse any non-standard notation. + +## API + +### Constants + +The following constants are exported from the top-level module: + +```ts +// colors +export const WHITE = 'w' +export const BLACK = 'b' + +// pieces +export const PAWN = 'p' +export const KNIGHT = 'n' +export const BISHOP = 'b' +export const ROOK = 'r' +export const QUEEN = 'q' +export const KING = 'k' + +// starting position (in FEN) +export const DEFAULT_POSITION = 'rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1' + +// square list +export const SQUARES = ['a8', 'b8', 'c8', ..., 'f1', 'g1', 'h1'] +``` + +### Constructor: Chess([ fen ], { skipValidation = false } = {}) + +The Chess() constructor creates a new chess object that default to the initial +board position.

It uses the 0x88 Move Generation Algorithm which internally + * stores the board as an 8x16 array. This is purely for efficiency but has a + * couple of interesting benefits: + * + * 1. 0x88 offers a very inexpensive "off the board" check. Bitwise AND (&) any + * square with 0x88, if the result is non-zero then the square is off the + * board. For example, assuming a knight square A8 (0 in 0x88 notation), + * there are 8 possible directions in which the knight can move. These + * directions are relative to the 8x16 board and are stored in the + * PIECE_OFFSETS map. One possible move is A8 - 18 (up one square, and two + * squares to the left - which is off the board). 0 - 18 = -18 & 0x88 = 0x88 + * (because of two-complement representation of -18). The non-zero result + * means the square is off the board and the move is illegal. Take the + * opposite move (from A8 to C7), 0 + 18 = 18 & 0x88 = 0. A result of zero + * means the square is on the board. + * + * 2. The relative distance (or difference) between two squares on a 8x16 board + * is unique and can be used to inexpensively determine if a piece on a + * square can attack any other arbitrary square. For example, let's see if a + * pawn on E7 can attack E2. The difference between E7 (20) - E2 (100) is + * -80. We add 119 to make the ATTACKS array index non-negative (because the + * worst case difference is A8 - H1 = -119). The ATTACKS array contains a + * bitmask of pieces that can attack from that distance and direction. + * ATTACKS[-80 + 119=39] gives us 24 or 0b11000 in binary. Look at the + * PIECE_MASKS map to determine the mask for a given piece type. In our pawn + * example, we would check to see if 24 & 0x1 is non-zero, which it is + * not.

It uses the 0x88 Move Generation Algorithm which internally + * stores the board as an 8x16 array. This is purely for efficiency but has a + * couple of interesting benefits: + * + * 1. 0x88 offers a very inexpensive "off the board" check. Bitwise AND (&) any + * square with 0x88, if the result is non-zero then the square is off the + * board. For example, assuming a knight square A8 (0 in 0x88 notation), + * there are 8 possible directions in which the knight can move. These + * directions are relative to the 8x16 board and are stored in the + * PIECE_OFFSETS map. One possible move is A8 - 18 (up one square, and two + * squares to the left - which is off the board). 0 - 18 = -18 & 0x88 = 0x88 + * (because of two-complement representation of -18). The non-zero result + * means the square is off the board and the move is illegal. Take the + * opposite move (from A8 to C7), 0 + 18 = 18 & 0x88 = 0. A result of zero + * means the square is on the board. + * + * 2. The relative distance (or difference) between two squares on a 8x16 board + * is unique and can be used to inexpensively determine if a piece on a + * square can attack any other arbitrary square. For example, let's see if a + * pawn on E7 can attack E2. The difference between E7 (20) - E2 (100) is + * -80. We add 119 to make the ATTACKS array index non-negative (because the + * worst case difference is A8 - H1 = -119). The ATTACKS array contains a + * bitmask of pieces that can attack from that distance and direction. + * ATTACKS[-80 + 119=39] gives us 24 or 0b11000 in binary. Look at the + * PIECE_MASKS map to determine the mask for a given piece type. In our pawn + * example, we would check to see if 24 & 0x1 is non-zero, which it is + * not. So, naturally, a pawn on E7 can't attack a piece on E2. However, a + * rook can since 24 & 0x8 is non-zero. The only thing left to check is that + * there are no blocking pieces between E7 and E2. That's where the RAYS + * array comes in. It provides an offset (in this case 16) to add to E7 (20) + * to check for blocking pieces. E7 (20) + 16 = E6 (36) + 16 = E5 (52) etc. + */ +// prettier-ignore +// eslint-disable-next-line +const Ox88 = { + a8: 0, b8: 1, c8: 2, d8: 3, e8: 4, f8: 5, g8: 6, h8: 7, + a7: 16, b7: 17, c7: 18, d7: 19, e7: 20, f7: 21, g7: 22, h7: 23, + a6: 32, b6: 33, c6: 34, d6: 35, e6: 36, f6: 37, g6: 38, h6: 39, + a5: 48, b5: 49, c5: 50, d5: 51, e5: 52, f5: 53, g5: 54, h5: 55, + a4: 64, b4: 65, c4: 66, d4: 67, e4: 68, f4: 69, g4: 70, h4: 71, + a3: 80, b3: 81, c3: 82, d3: 83, e3: 84, f3: 85, g3: 86, h3: 87, + a2: 96, b2: 97, c2: 98, d2: 99, e2: 100, f2: 101, g2: 102, h2: 103, + a1: 112, b1: 113, c1: 114, d1: 115, e1: 116, f1: 117, g1: 118, h1: 119 +}; +const PAWN_OFFSETS = { + b: [16, 32, 17, 15], + w: [-16, -32, -17, -15], +}; +const PIECE_OFFSETS = { + n: [-18, -33, -31, -14, 18, 33, 31, 14], + b: [-17, -15, 17, 15], + r: [-16, 1, 16, -1], + q: [-17, -16, -15, 1, 17, 16, 15, -1], + k: [-17, -16, -15, 1, 17, 16, 15, -1], +}; +// prettier-ignore +const ATTACKS = [ + 20, 0, 0, 0, 0, 0, 0, 24, 0, 0, 0, 0, 0, 0, 20, 0, + 0, 20, 0, 0, 0, 0, 0, 24, 0, 0, 0, 0, 0, 20, 0, 0, + 0, 0, 20, 0, 0, 0, 0, 24, 0, 0, 0, 0, 20, 0, 0, 0, + 0, 0, 0, 20, 0, 0, 0, 24, 0, 0, 0, 20, 0, 0, 0, 0, + 0, 0, 0, 0, 20, 0, 0, 24, 0, 0, 20, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 0, 20, 2, 24, 2, 20, 0, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 0, 2, 53, 56, 53, 2, 0, 0, 0, 0, 0, 0, + 24, 24, 24, 24, 24, 24, 56, 0, 56, 24, 24, 24, 24, 24, 24, 0, + 0, 0, 0, 0, 0, 2, 53, 56, 53, 2, 0, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 0, 20, 2, 24, 2, 20, 0, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 20, 0, 0, 24, 0, 0, 20, 0, 0, 0, 0, 0, + 0, 0, 0, 20, 0, 0, 0, 24, 0, 0, 0, 20, 0, 0, 0, 0, + 0, 0, 20, 0, 0, 0, 0, 24, 0, 0, 0, 0, 20, 0, 0, 0, + 0, 20, 0, 0, 0, 0, 0, 24, 0, 0, 0, 0, 0, 20, 0, 0, + 20, 0, 0, 0, 0, 0, 0, 24, 0, 0, 0, 0, 0, 0, 20 +]; +// prettier-ignore +const RAYS = [ + 17, 0, 0, 0, 0, 0, 0, 16, 0, 0, 0, 0, 0, 0, 15, 0, + 0, 17, 0, 0, 0, 0, 0, 16, 0, 0, 0, 0, 0, 15, 0, 0, + 0, 0, 17, 0, 0, 0, 0, 16, 0, 0, 0, 0, 15, 0, 0, 0, + 0, 0, 0, 17, 0, 0, 0, 16, 0, 0, 0, 15, 0, 0, 0, 0, + 0, 0, 0, 0, 17, 0, 0, 16, 0, 0, 15, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 0, 17, 0, 16, 0, 15, 0, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 0, 0, 17, 16, 15, 0, 0, 0, 0, 0, 0, 0, + 1, 1, 1, 1, 1, 1, 1, 0, -1, -1, -1, -1, -1, -1, -1, 0, + 0, 0, 0, 0, 0, 0, -15, -16, -17, 0, 0, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 0, -15, 0, -16, 0, -17, 0, 0, 0, 0, 0, 0, + 0, 0, 0, 0, -15, 0, 0, -16, 0, 0, -17, 0, 0, 0, 0, 0, + 0, 0, 0, -15, 0, 0, 0, -16, 0, 0, 0, -17, 0, 0, 0, 0, + 0, 0, -15, 0, 0, 0, 0, -16, 0, 0, 0, 0, -17, 0, 0, 0, + 0, -15, 0, 0, 0, 0, 0, -16, 0, 0, 0, 0, 0, -17, 0, 0, + -15, 0, 0, 0, 0, 0, 0, -16, 0, 0, 0, 0, 0, 0, -17 +]; +const PIECE_MASKS = { p: 0x1, n: 0x2, b: 0x4, r: 0x8, q: 0x10, k: 0x20 }; +const SYMBOLS = 'pnbrqkPNBRQK'; +const PROMOTIONS = [KNIGHT, BISHOP, ROOK, QUEEN]; +const RANK_1 = 7; +const RANK_2 = 6; +/* + * const RANK_3 = 5 + * const RANK_4 = 4 + * const RANK_5 = 3 + * const RANK_6 = 2 + */ +const RANK_7 = 1; +const RANK_8 = 0; +const SIDES = { + [KING]: BITS.KSIDE_CASTLE, + [QUEEN]: BITS.QSIDE_CASTLE, +}; +const ROOKS = { + w: [ + { square: Ox88.a1, flag: BITS.QSIDE_CASTLE }, + { square: Ox88.h1, flag: BITS.KSIDE_CASTLE }, + ], + b: [ + { square: Ox88.a8, flag: BITS.QSIDE_CASTLE }, + { square: Ox88.h8, flag: BITS.KSIDE_CASTLE }, + ], +}; +const SECOND_RANK = { b: RANK_7, w: RANK_2 }; +const SAN_NULLMOVE = '--'; +// Extracts the zero-based rank of an 0x88 square. +function rank(square) { + return square >> 4; +} +// Extracts the zero-based file of an 0x88 square. +function file(square) { + return square & 0xf; +} +function isDigit(c) { + return '0123456789'.indexOf(c) !== -1; +} +// Converts a 0x88 square to algebraic notation. +function algebraic(square) { + const f = file(square); + const r = rank(square); + return ('abcdefgh'.substring(f, f + 1) + + '87654321'.substring(r, r + 1)); +} +function swapColor(color) { + return color === WHITE ?

It uses the 0x88 Move Generation Algorithm which internally + * stores the board as an 8x16 array. This is purely for efficiency but has a + * couple of interesting benefits: + * + * 1. 0x88 offers a very inexpensive "off the board" check. Bitwise AND (&) any + * square with 0x88, if the result is non-zero then the square is off the + * board. For example, assuming a knight square A8 (0 in 0x88 notation), + * there are 8 possible directions in which the knight can move. These + * directions are relative to the 8x16 board and are stored in the + * PIECE_OFFSETS map. One possible move is A8 - 18 (up one square, and two + * squares to the left - which is off the board). 0 - 18 = -18 & 0x88 = 0x88 + * (because of two-complement representation of -18). The non-zero result + * means the square is off the board and the move is illegal. Take the + * opposite move (from A8 to C7), 0 + 18 = 18 & 0x88 = 0. A result of zero + * means the square is on the board. + * + * 2. The relative distance (or difference) between two squares on a 8x16 board + * is unique and can be used to inexpensively determine if a piece on a + * square can attack any other arbitrary square. For example, let's see if a + * pawn on E7 can attack E2. The difference between E7 (20) - E2 (100) is + * -80. We add 119 to make the ATTACKS array index non-negative (because the + * worst case difference is A8 - H1 = -119). The ATTACKS array contains a + * bitmask of pieces that can attack from that distance and direction. + * ATTACKS[-80 + 119=39] gives us 24 or 0b11000 in binary. Look at the + * PIECE_MASKS map to determine the mask for a given piece type. In our pawn + * example, we would check to see if 24 & 0x1 is non-zero, which it is + * not. So, naturally, a pawn on E7 can't attack a piece on E2. However, a + * rook can since 24 & 0x8 is non-zero. The only thing left to check is that + * there are no blocking pieces between E7 and E2. That's where the RAYS + * array comes in. It provides an offset (in this case 16) to add to E7 (20) + * to check for blocking pieces. E7 (20) + 16 = E6 (36) + 16 = E5 (52) etc. + */ + +// prettier-ignore +// eslint-disable-next-line +const Ox88: Record = { + a8: 0, b8: 1, c8: 2, d8: 3, e8: 4, f8: 5, g8: 6, h8: 7, + a7: 16, b7: 17, c7: 18, d7: 19, e7: 20, f7: 21, g7: 22, h7: 23, + a6: 32, b6: 33, c6: 34, d6: 35, e6: 36, f6: 37, g6: 38, h6: 39, + a5: 48, b5: 49, c5: 50, d5: 51, e5: 52, f5: 53, g5: 54, h5: 55, + a4: 64, b4: 65, c4: 66, d4: 67, e4: 68, f4: 69, g4: 70, h4: 71, + a3: 80, b3: 81, c3: 82, d3: 83, e3: 84, f3: 85, g3: 86, h3: 87, + a2: 96, b2: 97, c2: 98, d2: 99, e2: 100, f2: 101, g2: 102, h2: 103, + a1: 112, b1: 113, c1: 114, d1: 115, e1: 116, f1: 117, g1: 118, h1: 119 +} + +const PAWN_OFFSETS = { + b: [16, 32, 17, 15], + w: [-16, -32, -17, -15], +} + +const PIECE_OFFSETS = { + n: [-18, -33, -31, -14, 18, 33, 31, 14], + b: [-17, -15, 17, 15], + r: [-16, 1, 16, -1], + q: [-17, -16, -15, 1, 17, 16, 15, -1], + k: [-17, -16, -15, 1, 17, 16, 15, -1], +} + +// prettier-ignore +const ATTACKS = [ + 20, 0, 0, 0, 0, 0, 0, 24, 0, 0, 0, 0, 0, 0,20, 0, + 0,20, 0, 0, 0, 0, 0, 24, 0, 0, 0, 0, 0,20, 0, 0, + 0, 0,20, 0, 0, 0, 0, 24, 0, 0, 0, 0,20, 0, 0, 0, + 0, 0, 0,20, 0, 0, 0, 24, 0, 0, 0,20, 0, 0, 0, 0, + 0, 0, 0, 0,20, 0, 0, 24, 0, 0,20, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 0,20, 2, 24, 2,20, 0, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 0, 2,53, 56, 53, 2, 0, 0, 0, 0, 0, 0, + 24,24,24,24,24,24,56, 0, 56,24,24,24,24,24,24, 0, + 0, 0, 0, 0, 0, 2,53, 56, 53, 2, 0, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 0,20, 2, 24, 2,20, 0, 0, 0, 0, 0, 0, + 0, 0, 0, 0,20, 0, 0, 24, 0, 0,20, 0, 0, 0, 0, 0, + 0, 0, 0,20, 0, 0, 0, 24, 0, 0, 0,20, 0, 0, 0, 0, + 0, 0,20, 0, 0, 0, 0, 24, 0, 0, 0, 0,20, 0, 0, 0, + 0,20, 0, 0, 0, 0, 0, 24, 0, 0, 0, 0, 0,20, 0, 0, + 20, 0, 0, 0, 0, 0, 0, 24, 0, 0, 0, 0, 0, 0,20 +]; + +// prettier-ignore +const RAYS = [ + 17, 0, 0, 0, 0, 0, 0, 16, 0, 0, 0, 0, 0, 0, 15, 0, + 0, 17, 0, 0, 0, 0, 0, 16, 0, 0, 0, 0, 0, 15, 0, 0, + 0, 0, 17, 0, 0, 0, 0, 16, 0, 0, 0, 0, 15, 0, 0, 0, + 0, 0, 0, 17, 0, 0, 0, 16, 0, 0, 0, 15, 0, 0, 0, 0, + 0, 0, 0, 0, 17, 0, 0, 16, 0, 0, 15, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 0, 17, 0, 16, 0, 15, 0, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 0, 0, 17, 16, 15, 0, 0, 0, 0, 0, 0, 0, + 1, 1, 1, 1, 1, 1, 1, 0, -1, -1, -1,-1, -1, -1, -1, 0, + 0, 0, 0, 0, 0, 0,-15,-16,-17, 0, 0, 0, 0, 0, 0, 0, + 0, 0, 0, 0, 0,-15, 0,-16, 0,-17, 0, 0, 0, 0, 0, 0, + 0, 0, 0, 0,-15, 0, 0,-16, 0, 0,-17, 0, 0, 0, 0, 0, + 0, 0, 0,-15, 0, 0, 0,-16, 0, 0, 0,-17, 0, 0, 0, 0, + 0, 0,-15, 0, 0, 0, 0,-16, 0, 0, 0, 0,-17, 0, 0, 0, + 0,-15, 0, 0, 0, 0, 0,-16, 0, 0, 0, 0, 0,-17, 0, 0, + -15, 0, 0, 0, 0, 0, 0,-16, 0, 0, 0, 0, 0, 0,-17 +]; + +const PIECE_MASKS = { p: 0x1, n: 0x2, b: 0x4, r: 0x8, q: 0x10, k: 0x20 } + +const SYMBOLS = 'pnbrqkPNBRQK' + +const PROMOTIONS: PieceSymbol[] = [KNIGHT, BISHOP, ROOK, QUEEN] + +const RANK_1 = 7 +const RANK_2 = 6 +/* + * const RANK_3 = 5 + * const RANK_4 = 4 + * const RANK_5 = 3 + * const RANK_6 = 2 + */ +const RANK_7 = 1 +const RANK_8 = 0 + +const SIDES = { + [KING]: BITS.KSIDE_CASTLE, + [QUEEN]: BITS.QSIDE_CASTLE, +} + +const ROOKS = { + w: [ + { square: Ox88.a1, flag: BITS.QSIDE_CASTLE }, + { square: Ox88.h1, flag: BITS.KSIDE_CASTLE }, + ], + b: [ + { square: Ox88.a8, flag: BITS.QSIDE_CASTLE }, + { square: Ox88.h8, flag: BITS.KSIDE_CASTLE }, + ], +} + +const SECOND_RANK = { b: RANK_7, w: RANK_2 } + +const TERMINATION_MARKERS = ['1-0', '0-1', '1/2-1/2', '*'] + +const SAN_NULLMOVE = '--' + +// Extracts the zero-based rank of an 0x88 square. +function rank(square: number): number { + return square >> 4 +} + +// Extracts the zero-based file of an 0x88 square. +function file(square: number): number { + return square & 0xf +} + +function isDigit(c: string): boolean { + return '0123456789'.indexOf(c) !== -1 +} + +// Converts a 0x88 square to algebraic notation. +function algebraic(square: number): Square { + const f = file(square) + const r = rank(square) + return ('abcdefgh'.substring(f, f + 1) + + '87654321'.substring(r, r + 1)) as Square +} + +function swapColor(color: Color): Color { + return color === WHITE ?

This library always aims at supporting one EOLed LTS release which by this time now is 12.x which has reached EOL 30 Apr 2022. + +- Remove the minified UMD build from the package. + + Minified code is hard to audit and since this is a widely used library it seems more appropriate nowadays to optimize for auditability than to ship a legacy module format that, at best, serves educational purposes nowadays. + + For production browser use cases, users should be using a bundler. For educational purposes, today's online sandboxes like replit.com offer convenient ways to load npm modules, so the use case for UMD through repos like UNPKG or jsDelivr has largely vanished. + +- Drop IE 11 and Safari 10 support. Drop support for browsers that don't correctly implement const/let and default arguments, and no longer transpile the browser build to ES2015. + + This also removes the fallback on msCrypto instead of the crypto API. + + Browser tests are run in the first supported version of each supported browser and in the latest (as of this commit) version available on Browserstack. + +### Features + +-
