Isotope v3 is Metafizzy's flagship product — the best JavaScript library for filtering and sorting dynamic layouts. It just got a whole lot better with new version 3. We dropped support for IE8 & 9, and Android 2.3. In doing so, we were able to shed 800 lines of code to make Isotope's filesize 20% smaller. We added a new option to stagger item transitions (finally).

Staggered transitions are a small change to animation behavior, but the result is subtly compelling. The reveal and hide animations appear more natural.

See the Pen Isotope - stagger by David DeSandro (@desandro) on CodePen.

We simplified using Isotope with Webpack. Now your webpack.config.js only requires two aliases.

module.exports = {
  resolve: {
    alias: {
      'masonry': 'masonry-layout',
      'isotope': 'isotope-layout'
    }
  }
};

Best part: Isotope v3 is backward compatible with Isotope v2. Upgrade worry free. All your previous code will continue to work: jQuery plugin, events, methods, etc.

Open-source projects rarely get to version 2. I'm proud that Isotope has made it all the way to version 3.

We've been pushing out a bunch major version upgrades to our projects in 2016: Masonry v4, imagesLoaded v3, Packery v2, now Isotope v3. Next up: Flickity v2.
