onFrame

Returns a function, that, as long as it continues to be invoked, will not be triggered. The function will be called after N (frameLength) animation frames.

API

  const debounce = onFrame(fn, frameLength = 10);

fn

Callback function

frameLength

Length of frames to wait before callback is called.

NOTE: Setting the frameLength to 1 will call the callback on the first frame.

Cancel

It is possible to cancel a running debounced function, by calling cancel on the return object

  debounce.cancel();

Example

import onFrame from 'onframe';

const efficientResize = onFrame(function() {
  // will be debounced to after 5 frames
}, 5);

window.addEventListener('resize', efficientResize);

// Somewhere else
efficientResize.cancel();
