A general framework and library for visual piling/stacking.

Piling.js currently supports visual piling of images, matrices, and SVG out of the box, but can easily be customized with your own render.

Get Started

Install

npm install piling.js pixi.js

PixiJS is the underlying WebGL rendering engine. It's not pre-bundled in case your application needs to use PixiJS elsewhere.

Optionally, if you want to lay out piles by more than two attributes you have to install UMAP as follows.

npm install umap-js

Quick Start

Let's pile some natural images

import createPilingJs, { createImageRenderer } from 'piling.js';

// define your items
const items = [{ src: 'http://example.com/my-fancy-photo.png' }, ...];

// instantiate a matching the data type of your items
const itemRenderer = createImageRenderer();

const piling = createPilingJs(
  document.getElementById('demo'), // dom element in which piling.js will be rendered
  {
    // Mandatory: add the items and corresponding renderer
    items,
    itemRenderer,
    // Optional: configure the view specification
    columns: 4
  }
);

Et voilà 🎉
