jschessrulz

JavaScript chess rules library

Requirements

Node.js (https://nodejs.org/en/)

Note that jschessrulz is written with some es2015 features, so your project's build system has to be able to handle those.

Installation

npm install jschessrulz --save

Usage

import or require jschessrulz in your js-file

To start a new chess game simply declare:

  var chess = new Chess()

To select or move a piece use coordinates (0-7 for both x and y):

selectPiece(x, y) {
	if (!this.chess.selected || this.chess.canSetSelected(x, y)) {
		this.chess.setSelected(x, y)
	} else if (this.chess.isMovable(x, y)) {
		this.chess.movePiece(this.chess.selected, new Position(x, y))
	}
}

To determine whether game is over call:

  chess.isGameOver()
