Flexible

  • Native DOM support: CSS, SVG, SVG path and DOM attribute support, out of the box.
  • Unlimited: Custom callbacks allow you output to any numerical property or API.
  • Power anything: Use with jQuery, Canvas, Three.js, WebSockets, etc.
  • Seamless interaction: Tracks velocity for hand-off between input, animation and physics.
  • Node support: Run on a server or an Arduino to fuel the IoT.
  • Open rAF loop: Run any Process on the core requestAnimationFrame loop.

Extendable

Develop your own:

  • Easing: Easing functions and bezier curves.
  • Physics: Add new physics simulators.
  • Input: Create custom Input interfaces for Oculus/Leap/anything.
  • Roles: Extend our CSS/SVG/Attr support with routes for Canvas, Three.js, Google Map Symbols or any standardised numerical property.
  • Value types: Automatically split special values in child values (ie "#000" -> { Red: 0, Green: 0, Blue: 0, Alpha: 1 } or more complex strings like path definitions.

Performant

  • Uses and exposes a single requestAnimationFrame thread that automatically winds down when not in use.
  • Never reads the DOM, leaving you in total control of performance.
  • The same size as Velocity.js, over 66% smaller than GreenSock TweenMax. Boom shak shakalaka.
