Touch Events

This is a nice and quick utility I learned recently to support both TouchEvents and MouseEvents while only worrying about the onClick prop.

This probably doesn’t support all use cases.

getTouchEvents takes a callback that is invoked (or not) by either the onClick or onTouchStart handlers, depending on the environment.

function getTouchEvents(callback) {
  if (callback) {
    if (window && "ontouchstart" in window) {
      return {
        onTouchStart: callback,
        onClick: noop
    } else {
      return {
        onTouchStart: noop,
        onClick: callback

Finally, add this utility to your design system’s Button primitive:

function Button({ onClick, children }) {
  const touchEvents = getTouchEvents(onClick);
  return <button {...touchEvents}>{children}</button>;

function App() {
  return (
      <Button onClick={() => alert("onClick")}>Click</Button>
      <Button onClick={() => alert("onTouchStart")}>Touch</Button>
