useTimeout
A react wrapper for setTimeout – no leaks on unmount!
Use this hook if you want a function that executes the provided callback after the specified amount of time.
This will not debounce or throttle the callbacks, i.e. consecutive calls of this function will all spawn new timeouts even if some are still pending. If you want a debouncing version, take a look at useDebounce(). If you want a throttling version, see useThrottle().
Pending timeouts will only(!) be cleared in case the component unmounts.
If you want to execute a timeout every time a certain value changes, useTimeoutEffect might be better suited.
Example
import { useTimeout } from 'react-timing-hooks'
// Hide something after 2 seconds
const hideDelayed = useTimeout(() => setHide(true), 2000)
return <button onClick={hideDelayed}>Hide!</button>
API
Params
useTimeout(callback, timeout)
| Name | Description |
|---|---|
| callback | a function that will be invoked as soon as the timeout expires |
| timeout | the timeout in milliseconds |
Return value
A function will be returned, that - once executed - will run the callback-function after {timeout} milliseconds. The function will also return the timeout id in case you want to clear it manually via clearTimeout(id).
Notes
This hook will automatically clear any pending timeout on unmount. Timeout’s can be cleared manually as well (see “Return value”).
