Waterfall.js

Tired of using creepy hacks or heavy ways to get a grid based on Pinterest?

1KB and works without any dependency, also UMD support available too \o/

The "Why"

Currently the best option today to do this job is Masonry, but it's very heavy and has a jQuery dependency. Please understand: this isn't a problem in most cases, but when perfomance and page weight matters, it's best to try other options: maybe pure CSS? Is it possible?

This question has a good point. Yes, there are CSS ways to solve this, using flexbox or columns technic, but this doesn't work well when you don't know about your data/structure. So we have to use JavaScript. The challenge is create a decent algorithm where the structure doesn't matter: Waterfall will work.

However; Waterfall always will consider items with same width :)

How to Use?

Getting

First at all, get Waterfall using Download Option

Get it using npm or yarn by running this command

npm install waterfall.js@1.0.2

or

yarn add waterfall.js@1.0.2

⚠️ The latest stable is waterfall-1.0.2 (which is used in the website), newest versions are suffering issues from a major rewrite.

You can import

import waterfall from 'waterfall.js/src/waterfall'

Or add the source before the closing body tag:

<script src="waterfall.min.js"></script>
</body>

Another option: Waterfall.js is currently available in cdnjs, so you can use it from there too.

<script src="//cdnjs.cloudflare.com/ajax/libs/waterfall.js/1.0.2/waterfall.min.js"></script>
</body>

Usage

Define your grid structure:

<div class="grid">
    <div class="item">Solid Snake</div>
    <div class="item">Riou</div>
    <div class="item">Jack Russel</div>
</div>

Call Waterfall function with your grid as a argument and let the magic happen :)

waterfall('.grid');
// or
var grid = document.querySelector('.grid');
waterfall(grid);

Responsive

Just call Waterfall function again on window resize event:

window.addEventListener('resize', function () {
    waterfall(grid);
});

Many images to load

In this case we highly recommend you run the waterfall only after the images have been loaded. Because Waterfall.js requires information about height / width of the images.

A quick solution is to use imgStatus (no dependencies and only 855bytes) to check the images were loaded.
