React swipe and touch event handler component & hook
React hooks have been released with 16.8.0 🎉
v5 of react-swipeable
includes a hook, useSwipeable
, that provides the same great functionality as <Swipeable>
. See the useSwipeable
hook in action with this codesandbox.
The component is still included and migration to v5 is straightforward. Please see the migration doc for more details including more info on the simplified api.
$ npm install react-swipeable
Use React-hooks or a Component and set your swipe(d) handlers.
import { useSwipeable, Swipeable } from 'react-swipeable'
const handlers = useSwipeable({ onSwiped: (eventData) => eventHandler, ...config })
return (<div {...handlers}> You can swipe here </div>)
Spread handlers
onto the element you wish to track swipes inside of. Details below.
<Swipeable onSwiped={(eventData) => eventHandler} {...config} >
You can swipe here!
</Swipeable>
The Component <Swipeable>
uses a <div>
by default under the hood to attach event handlers to.
{
onSwiped, // Fired after any swipe
onSwipedLeft, // Fired after LEFT swipe
onSwipedRight, // Fired after RIGHT swipe
onSwipedUp, // Fired after UP swipe
onSwipedDown, // Fired after DOWN swipe
onSwiping, // Fired during any swipe
}
All Event Handlers are called with the below event data.
{
event, // source event
deltaX, // x offset (current.x - initial.x)
deltaY, // y offset (current.y - initial.y)
absX, // absolute deltaX
absY, // absolute deltaY
velocity, // √(absX^2 + absY^2) / time
dir, // direction of swipe (Left|Right|Up|Down)
}
{
delta: 10, // min distance(px) before a swipe starts
preventDefaultTouchmoveEvent: false, // preventDefault on touchmove, *See Details*
trackTouch: true, // track touch input
trackMouse: false, // track mouse input
rotationAngle: 0, // set a rotation angle
}
{
nodeName: 'div', // internally rendered component dom node
innerRef // callback ref for internal component dom node
}
None of the props/config options are required.
- Hook use requires react >= 16.8.0
- The props contained in
handlers
are currentlyref
andonMouseDown
- Please spread
handlers
as the props contained in it could change as react improves event listening capabilities- See #127 for some more context
- Please spread
preventDefaultTouchmoveEvent
prevents the browser's touchmove event. Use this to stop the browser from scrolling while a user swipes.
e.preventDefault()
is only called when:preventDefaultTouchmoveEvent: true
trackTouch: true
- the users current swipe has an associated
onSwiping
oronSwiped
handler/prop
Example:
- If a user is swiping right with
<Swipable onSwipedRight={this.userSwipedRight} preventDefaultTouchmoveEvent={true} >
thene.preventDefault()
will be called, but if the user was swiping left thene.preventDefault()
would not be called.
Please experiment with the example to test preventDefaultTouchmoveEvent
.
Initial set up, with node 10+
, run npm install
