A WICG proposal and polyfill extending the DOM event pattern with EventListenerOptions, allowing developers to register passive event listeners that opt out of preventDefault. The work has been merged into the official WHATWG DOM spec and is now natively supported by all major browsers, so this repository is preserved only as an archive.

Use cases

  • improve scroll performance on touch and wheel events
  • register passive event listeners in older browsers
  • disable preventDefault for event listeners
  • polyfill EventListenerOptions support
  • reduce jank from non-passive touch listeners

When to choose

  • you need to support very old browsers lacking native passive listener support
  • you want the original explainer and polyfill for reference

When to avoid

  • you target modern browsers, which support passive listeners natively
  • you need an actively maintained library
  • you want to file issues or contribute - use the WHATWG DOM spec repo instead
