blocks

Headless falling-block engine. It installs no input listeners and never draws.

import { createGame } from 'blocks';

const game = createGame({
  seed: 42,
  onRender: (state, canvas) => renderBoard(state, canvas),
});

game.moveLeft();
game.hardDrop();
game.step(16);

const saved = game.getState();
const resumed = createGame({ state: saved });

const tPiece = game.pieces.T;
const iPiece = game.getPiece('I');

Use setState() or setBoard() to configure scenarios. peekNextPiece(), setNextPieces(), and spawnNextPiece() control piece sequencing. Call start() only when a browser RAF loop is wanted; otherwise call step() and render() yourself.
