TypeScript Chess Engine

Introduction

• Hello! Welcome to my chess engine. This was my exploration into object orientated programming using TypeScript.
• When creating this project, I tried to stick to SOLID principles as much as possible, but this was my first time so go easy on me.

How To Use

• So first of all, you'll need to create a new Game:

import { Game } from "ChessGame";

const game = new Game();

• If you want to create a new game with custom pieces, you will have to create an array with the pieces you want and pass it as an argument when you create the game:
• ACHTUNG MINEFIELD - The colours 'White' and 'Black' are represented by the numbers 0 and 1 respectively. This is because I wanted to use an enum. I'm aware that if something is one of two things it should be a boolean but this is my engine so sue me.

const pieces = [
  { piece: "Kg4", colour: 0 },
  { piece: "Nd3", colour: 1 },
  { piece: "d4", colour: 1 },
];

const game = new Game(pieces);

// Will spawn a white king on square g4, a black knight on square d3, and a black pawn on square d4

• Also worthy of note is that I use standard chess notation as much as possible, so...

  • Named pieces are notated thus:
    • K - King
    • Q - Queen
    • R - Rook
    • N - Knight
    • B - Bishop
  • Pawns aren't notated, so if you just pass in a square it will generate a pawn in that square.

Moving a piece

• The current colour's move can be found by running:

import { isWhiteMove } from "ChessGame";

console.log(isWhiteMove); // logs true/false

The game will alternate the current colour at the end of the turn. This IS a boolean.
