2048-ts-engine handles logic for 2048 game. Despite being written in Typescript, you can also use plain JS, if TS is not needed.

yarn add 2048-ts-engine

• The lib returns two main functions
  • startGame - simply starting the game
  • move
    • evaluating move, calculating points, board coordination etc,
    • accepts these parameters

  direction: Direction
  game: Game

Both these functions return all game related data (board coordinates, score, status etc.) which look like this:

{
  "score": 16,
  "board": [
    [ 0, 0, 4, 0 ],
    [ 0, 0, 0, 0 ],
    [ 2, 0, 0, 0 ],
    [ 4, 8, 0, 8 ]
  ],
  "gameStatus": "STARTED"
}

You will need to store the current state somewhere, since the engine only processes the game, and after every move, the current state of game is returned.

import { startGame, move } from '2048-ts-engine';
import { Direction, Game, GameStatus } from '2048-ts-engine/src/types';

const newGame = startGame();
const gameProcessed = move(Direction.UP, newGame);
