use-ref-callback

Handy hook to define or wrap argument callback to pass to memoized components

Install

npm install --save use-ref-callback

Usage

import * as React from 'react'
import api from "./api"

import useRefCallback from 'use-ref-callback'
// Or: import { useRefCallback } from 'use-ref-callback'

function ExampleInput({ onChange }: { onChange?: string }) {
  // Even if onChange will be changing over time the handleChange will remain the same
  const handleChange = useRefCallback(onChange)
  // as so the render of ExampleInput won't trigger rerender of memoized children
  return <MemoizedInput onChange={handleChange} />
}

function ExampleForm() {
  const [data, setData] = React.useState()

  // handleSubmit will never change, yet it will always use the latest values from the component scope
  const handleSubmit = useRefCallback((event) => {
    event.preventDefault()
    api.submit(data)
  })

  // ...
    <MemoizedForm onSubmit={handleSubmit}>
