Preact Gestures
Preact compatible higher order components for gesture detection
npm i preact-gestures
Gesture detection made easy, even in preact
- Simple, and easy to use:
<CompWithGestures onDragStart={dragStarted}>
- Lightweight: ~3kb minified, 1.5kb gzipped
- Multi platform: Handle gestures the same way across devices
- Built-in gesture detectors:
onMenu
right-click or long taponDrag
click&drag or tap, hold and dragStart
Move
End
- ... more in the works
Usage
import { h, render } from 'preact'
import { withGestures } from 'preact-gestures'
let MyComp = () => (
<div>I am a regular component</div>
)
let MyCompWithGestures = withGestures(MyComp)
render(<MyCompWithGestures onDragStart={() => console.log('I am being dragged!')}/>, document.body)

}
Returns
The passed in Component
