Data structures and utilities to represent the game of Go.

This library depends on Immutable.js and lodash.

Getting Started

Install godash via npm.

npm install godash

require and use it in your modules.

var godash = require('godash');
var board = godash.Board(19);
var tengen = godash.Coordinate(9, 9); // 0-based

board.moves.has(tengen); // false

var standardOpening = placeStone(
    board,
    tengen,
    godash.BLACK
);
standardOpening.moves.has(tengen); // true

Why Godash?

Godash provides the "primitives" for Go necessary for creating UIs that go beyond a simple SGF player. You can create whatever UI you want without having to reinvent the wheel every time.

Check out the documentation to see what Godash provides.

Breaking changes from version 1 to 2

• Due to upgrading to immutable@4, Board and Coordinate are no longer subclasses of Seq.
• Board constructor changed to take Move.

Version 2.5.0 - Immutable v5 upgrade

• Upgraded to immutable@5 with no breaking changes to the Godash API.
• All existing code remains compatible - no changes required.
