A fast & universal chesslibrary with Basic AI support. This is the core part of the @chesslib bundle.
This library is required for
- @chesslib/ai
- @chesslib/game
- @chesslib/plugin
npm install @chesslib/core
https://www.npmjs.com/package/@chesslib/core
Get all available moves
import { Chessboard, Positions, COLORS } from "@chesslib/core";
var board = Chessboard.fromPosition(Positions.default);
// Get all possible moves
var moves = board.getFENMoves();
if(board.tryMoveFEN(moves[0].from, moves[0].to))
{
console.log("Move was valid");
}Get all available moves for BLACK
// Get all possible moves for BLACK
var moves = board.getFENMoves(COLORS.BLACK);Get all available moves for A2 Pawn?
// Get all possible moves for BLACK
var moves = board.getFENMovesatFEN("a2");Validate if move is possible?
// Get all possible moves for BLACK
if(board.isValidMoveFEN("a2", "a4"))
{
console.log("Move is valid");
}Check if king was captured
// Get all possible moves
if(board.findPieces("K").length == 1)
{
console.log("GAME OVER!");

The AI is a simple implementation of a basic board evaluation. The AI is trying every moves possible confirming the board value is better for a given move. The search depth can be configured, and due to it's high CPU intensivity it is recommended to use it with webworkers in browsers, and run it as a seperate process or thread in nodejs if required.
AI REPO: https://github.com/azarus/chesslib-ai The example use of the AI is available in the repo under examples/ folder.
