Welcome to LeapJS

This is the place to find the latest LeapJS and plugins for your JavaScript project. You can find more setup instructions through our getting started page.


See the archive for older versions.



LeapJS provides a powerful and flexible extension framework that makes it easy to build and use custom plugins. They’re configurable, can extend frame objects (such as fingers or hands) with new functionality or data, and can emit custom events from the controller.

LeapJS-Plugins includes:

  • Hand Entry Emit events when a hand enters or leaves the field of view.
  • Hand Hold Save data onto hands or fingers to be persisted between frames.
  • Screen Position Get the on-screen position of any point in Leap-space.
  • Version Check Ensure a minimum protocol version when running your app.
  • Playback Record hand-data from the Leap, compress it, and use it to animate your app.
  • Transform Translate, rotate, and scale Leap Motion data. Use this to orient the hand for Virtual Reality.
  • Bone Hand Add a customizable 3D hand to your THREE.js scene in one line of code.

LeapJS 3D Widgets: Push buttons and drag planes

LeapJS-rigged-hand uses THREE.js to add a hand to any web page.
