useClick()

npm i @react-hook/click

---

A React hook for conditionally firing a function when an element is clicked - for instance if you only want a click even to fire on double-clicks.

Quick Start

import useClick from '@react-hook/click'

const Component = (props) => {
  // this onClick even will only fire if this was a double-click
  const maybeHandleClick = useClick('double', console.log)
  return <button onClick={maybeHandleClick}>Double-click me</button>
}
