🧩 🤯 Headbreaker

Jigsaw Puzzles Framework for JavaScript

headbreaker - a Spanish pun for rompecabezas - is a JavaScript framework for building all kind of jigsaw puzzles.

☑️ Features

100% pure JavaScript
Headless support domain-model
Highly tested
Customizable data-model
Zero-dependencies - although Konva.js is used a a rendering backed, it is an optional dependency which can be replaced with custom code

📦 Installing

npm install --save headbreaker

# optional: manually add konva to your project if you want to use
# it as rendering backend
npm install --save konva

⏳ TL;DR sample

If you just want to see a - very basic - 2x2 puzzle in your web-browser, then create an HTML file with the following contents 😁:

<script src="https://flbulgarelli.github.io/headbreaker/js/headbreaker.js"></script>
<body>
  <div id="puzzle"></div>
  <script>
    const autogen = new headbreaker.Canvas('puzzle', {
      width: 800, height: 650,
      pieceSize: 100, proximity: 20,
      borderFill: 10, strokeWidth: 2, lineSoftness: 0.18,
    });
    autogen.autogenerate({
      horizontalPiecesCount: 2,
      verticalPiecesCount: 2,
      metadata: [
        {color: '#B83361'},
        {color: '#B87D32'},
        {color: '#A4C234'},
        {color: '#37AB8C'}
      ]
    });
    autogen.draw();
  </script>
</body>

And voilà! 🎊

sample puzzle

However, there is a lot more that headbreaker can do for you. These are some of its coolest features:

Customizable pieces outlines
Irregular pieces
Image support
Sound support
Event system
Automatic validation
Data import and export

🏁 Quick start

headbreaker is a library which solves two different - but-related - problems:

It implements a jigsaw-like data-structure, which can be used in tasks like modelling, traversing, importing and exporting and - of course - rendering. This data-structure is 100% pure JavaScript, with no dependencies, and can be used both in browsers and headless environments.
It implements a simple and generic rendering system for the Web. headbreaker also ships a 100% functional Konva.js-based implementation, but you may want to develop and use your own implementation.

headbreaker is designed to be included and compiled in your project as a node module, but you can also import it directly in your static pages from https://flbulgarelli.github.io/headbreaker/js/headbreaker.js.

HTML Puzzle

<!-- just add a div with an id... -->
<div id="my-canvas">
</div>

<script>
  // ...and a script with the following code:
  let dali = new Image();
  dali.src = 'static/dali.jpg';
  dali.onload = () => {
    const canvas = new headbreaker.Canvas('my-canvas', {
      width: 800, height: 800, image: dali
    });
    canvas.autogenerate();
    canvas.shuffle(0.7);
    canvas.draw();
  }
</script>

Canvas is a visual representation of a Puzzle and as such, it mirrors many of the most common Puzzle methods - see next section for more details. However, if you need to access the associated Puzzle object, you can call puzzle accessor anytime:

// create and configure the canvas
const canvas = new headbreaker.Canvas(...);
// ...

// now you can access and interact with the puzzle object
const puzzle = canvas.puzzle;

Headless Puzzle

Headbreaker provides a Puzzle object which allows to fully manipulate its model and its individual Pieces. Since Puzzles are not coupled to any visual representation, it can be even loaded in headless environments, like in a node server:

const headbreaker = require('headbreaker');

// Create a puzzle
const puzzle = new headbreaker.Puzzle();
puzzle
  .newPiece({right: Tab})
  .locateAt(0, 0);
puzzle
  .newPiece({left: Slot, right: Tab})
  .locateAt(3, 0);
puzzle
  .newPiece({left: Slot, right: Tab, down: Slot})
  .locateAt(6, 0);
puzzle
  .newPiece({up: Tab})
  .locateAt(6, 3);

// Connect puzzle's nearby pieces
puzzle.autoconnect();

// Translate puzzle
puzzle.translate(10, 10);

// Shuffle pieces
puzzle.shuffle(100, 100);

// Relocate pieces to fit into a bounding box
// while preserving their relative positions, if possible
puzzle.reframe(vector(0, 0), vector(20, 20));

// Directly manipulate pieces
const [a, b, c, d] = puzzle.pieces;

// Drag a piece 10 steps right and 5 steps down
a.drag(10, 5);

// Connect two pieces (if possible)
a.tryConnectWith(b);

// Add custom metadata to pieces
a.metadata.flavour = "chocolate";
a.metadata.sugar = true;
b.metadata.flavour = "chocolate";
b.metadata.sugar = false;

c.metadata.flavour = "vainilla";
c.metadata.sugar = false;
d.metadata.flavour = "vainilla";
d.metadata.sugar = true;

// Require pieces to match a given condition in
// order to be connected
puzzle.attachConnectionRequirement((one, other) => one.metadata.flavour === other.metadata.flavour);

// Alternatively, set individual requirements for horizontal
// and vertical connections
puzzle.attachVerticalConnectionRequirement((one, other) => one.metadata.flavour === other.metadata.flavour);
puzzle.attachHorizontalConnectionRequirement((one, other) => one.metadata.sugar !== other.metadata.sugar);

// Remove all - vertical and horizontal - connection requirements
puzzle.clearConnectionRequirements();

// Export and import puzzle
const dump = puzzle.export();
const otherPuzzle = headbreaker.Puzzle.import(dump);

      painter: new painters.Konva() // <-- this is important. See https://github.com/flbulgarelli/headbreaker/issues/51
    });
