Import

Usage

useDebouncedValue hook debounces value changes. It is designed to work with controlled components.


import { useState } from 'react'
import { useDebouncedValue } from '@tidbcloud/uikit'
import { TextInput, Text } from '@tidbcloud/uikit'
 
function Demo() {
  const [value, setValue] = useState('')
  const [debounced] = useDebouncedValue(value, 500)
 
  return (
    <>
      <TextInput value={value} onChange={(e) => setValue(e.currentTarget.value)} placeholder="Type something..." />
      <Text mt="md">Value: {value}</Text>
      <Text>Debounced: {debounced}</Text>
    </>
  )
}

Differences from useDebouncedState

You have direct access to the non-debounced value
It is used for controlled inputs (value prop instead of defaultValue)
It works with props or other state providers

Leading Update

Immediately update value with first call using { leading: true }:


import { useDebouncedValue } from '@tidbcloud/uikit'
 
const [debounced] = useDebouncedValue(value, 500, { leading: true })

Cancel Update

The hook provides a cancel callback to cancel the pending update:


import { useState } from 'react'
import { useDebouncedValue } from '@tidbcloud/uikit'
import { TextInput, Button, Group } from '@tidbcloud/uikit'
 
function Demo() {
  const [value, setValue] = useState('')
  const [debounced, cancel] = useDebouncedValue(value, 1000)
 
  return (
    <>
      <TextInput value={value} onChange={(e) => setValue(e.currentTarget.value)} />
      <Group mt="md">
        <Button onClick={cancel}>Cancel</Button>
      </Group>
    </>
  )
}
