What is react-swipeable?
The react-swipeable package is a React component that provides easy-to-use swipe event handlers for touch devices. It allows developers to add swipe functionality to their React components, making it ideal for creating touch-friendly user interfaces.
What are react-swipeable's main functionalities?
Basic Swipe Detection
This code demonstrates how to use the react-swipeable package to detect basic swipe events. The `useSwipeable` hook is used to create swipe handlers, which are then applied to a div element. When a swipe is detected, a message is logged to the console.
import React from 'react';
import { useSwipeable } from 'react-swipeable';
const SwipeComponent = () => {
const handlers = useSwipeable({
onSwiped: (eventData) => console.log('User Swiped!', eventData)
});
return (
<div {...handlers} style={{ width: '100%', height: '100px', background: 'lightgray' }}>
Swipe here
</div>
);
};
export default SwipeComponent;
Swipe Direction Detection
This code demonstrates how to detect the direction of a swipe using the react-swipeable package. The `useSwipeable` hook is configured with handlers for each swipe direction (left, right, up, down), and logs a message to the console when a swipe in that direction is detected.
import React from 'react';
import { useSwipeable } from 'react-swipeable';
const SwipeDirectionComponent = () => {
const handlers = useSwipeable({
onSwipedLeft: () => console.log('Swiped Left!'),
onSwipedRight: () => console.log('Swiped Right!'),
onSwipedUp: () => console.log('Swiped Up!'),
onSwipedDown: () => console.log('Swiped Down!')
});
return (
<div {...handlers} style={{ width: '100%', height: '100px', background: 'lightblue' }}>
Swipe in any direction
</div>
);
};
export default SwipeDirectionComponent;
Swipe Threshold Configuration
This code demonstrates how to configure a swipe threshold using the react-swipeable package. The `useSwipeable` hook is configured with a `delta` value, which sets the minimum distance (in pixels) that a swipe must cover to be detected.
import React from 'react';
import { useSwipeable } from 'react-swipeable';
const SwipeThresholdComponent = () => {
const handlers = useSwipeable({
onSwiped: (eventData) => console.log('User Swiped!', eventData),
delta: 50 // Minimum distance (in pixels) for a swipe to be detected
});
return (
<div {...handlers} style={{ width: '100%', height: '100px', background: 'lightgreen' }}>
Swipe with a minimum threshold
</div>
);
};
export default SwipeThresholdComponent;
Other packages similar to react-swipeable
react-swipe
The react-swipe package provides a React component for touch slide navigation. It is similar to react-swipeable in that it allows for swipe detection, but it is more focused on creating swipeable carousels and sliders. It offers a higher-level abstraction compared to react-swipeable.
react-use-gesture
The react-use-gesture package is a set of hooks for handling gestures in React. It supports a wide range of gestures, including swipes, pinches, and scrolls. Compared to react-swipeable, react-use-gesture offers more comprehensive gesture support and can be used for more complex interactions.
react-swipeable-views
The react-swipeable-views package is a React component for creating swipeable views, such as tabs or carousels. It is similar to react-swipeable in that it provides swipe detection, but it is specifically designed for creating swipeable view containers. It offers built-in support for animations and transitions.
React Swipeable
React swipe event handler hook
Api
Use the hook and set your swipe(d) handlers.
const handlers = useSwipeable({
onSwiped: (eventData) => console.log("User Swiped!", eventData),
...config,
});
return <div {...handlers}> You can swipe here </div>;
Spread handlers
onto the element you wish to track swipes on.
Props / Config Options
Event handler props
{
onSwiped,
onSwipedLeft,
onSwipedRight,
onSwipedUp,
onSwipedDown,
onSwipeStart,
onSwiping,
onTap,
}
Details
onSwipeStart
- called only once per swipe at the start and before the first onSwiping
callback
- The
first
property of the SwipeEventData
will be true
Configuration props and default values
{
delta: 10,
preventDefaultTouchmoveEvent: false,
trackTouch: true,
trackMouse: false,
rotationAngle: 0,
}
Swipe Event Data
All Event Handlers are called with the below event data, SwipeEventData
.
{
event,
initial,
first,
deltaX,
deltaY,
absX,
absY,
velocity,
vxvy,
dir,
}
None of the props/config options are required.
Hook details
- Hook use requires react >= 16.8.3
- The props contained in
handlers
are currently ref
and onMouseDown
- Please spread
handlers
as the props contained in it could change as react improves event listening capabilities
preventDefaultTouchmoveEvent
details
This prop allows you to prevent the browser's touchmove event default action, mostly "scrolling".
Use this to stop scrolling in the browser while a user swipes.
- You can additionally try
touch-action
css property, see below
e.preventDefault()
is only called when:
preventDefaultTouchmoveEvent: true
trackTouch: true
- the users current swipe has an associated
onSwiping
or onSwiped
handler/prop
Example scenario:
If a user is swiping right with props { onSwipedRight: userSwipedRight, preventDefaultTouchmoveEvent: true }
then e.preventDefault()
will be called, but if the user was swiping left then e.preventDefault()
would not be called.
Please experiment with the example app to test preventDefaultTouchmoveEvent
.
passive listener
With v6 we've added the passive event listener option, by default, to internal uses of addEventListener
. We set the passive
option to false
only when preventDefaultTouchmoveEvent
is true
.
When preventDefaultTouchmoveEvent
is:
true
=> el.addEventListener(event, cb, { passive: false })
false
=> el.addEventListener(event, cb, { passive: true })
React's long running passive event issue.
We previously had issues with chrome lighthouse performance deducting points for not having passive option set.
Browser Support
The release of v6 react-swipeable
we only support browsers that support options object for addEventListener
, Browser compatibility. Which mainly means react-swipeable
does not support ie11 by default, you need to polyfill options. For example using event-listener-with-options.
Version 6 Updates and migration
If upgrading from v5 or later please refer to the release notes and the v6 migration doc
v6 now only exports a hook, useSwipeable
.
If would like something similar to the old <Swipeable>
component you can recreate it from the hook. There are examples in the migration doc.
FAQs
How can I add a swipe listener to the document
?
Example by @merrywhether #180
const { ref } = useSwipeable({
...
}) as { ref: RefCallback<Document> };
useEffect(() => {
ref(document);
});
How to share ref
from useSwipeable
?
Example ref passthrough, more details #189:
const MyComponent = () => {
const handlers = useSwipeable({ onSwiped: () => console.log('swiped') })
const myRef = React.useRef();
const refPassthrough = (el) => {
handlers.ref(el);
myRef.current = el;
}
return (<div {...handlers} ref={refPassthrough} />
}
How to use touch-action
to prevent scrolling?
Sometimes you don't want the body
of your page to scroll along with the user manipulating or swiping an item.
You might try to prevent the event default action via preventDefaultTouchmoveEvent, which calls event.preventDefault()
. But there may be a simpler, more effective solution, which has to do with a simple CSS property.
touch-action
is a CSS property that sets how an element's region can be manipulated by a touchscreen user.
const handlers = useSwipeable({
onSwiped: (eventData) => console.log("User Swiped!", evenData),
...config,
});
return <div {...handlers} style={{ touchAction: 'pan-y' }}> Swipe here </div>;
