Pillow Chess

A just-for-fun JS chess library riddled with suboptimal code. This was an exercise in problem solving, which meant no Googling for optimal solutions. This library is a WIP and isn't usable yet.

Installation

$ npm install pillow-chess

Usage

const pchess = require('pillow-chess');

Initialise an empty game:

const game = pchess.Game;

Place pieces using standard chess rules:

game.newGame({rules: 'standard'});

Move a piece using long algebraic notation:

game.movePiece('e2e4');

ASCII & Unicode

You can generate an ASCII or Unicode output of a board state:

ASCII:

let ascii = game.printASCII();

Unicode (experimental):

let unicode = game.printUnicode();

Example output:

console.log(ascii);
