What it does

Requires that components wrapped with forwardRef must have a ref parameter.

This rule checks all React components using forwardRef and verifies that there is a second parameter.

Why is this bad?

Omitting the ref argument is usually a bug, and components not using ref don’t need to be wrapped by forwardRef.

Examples

Failing

import React from "react";
 
const Example = React.forwardRef((props) => {
  //                             ^^^^^^^
  //                             - 'forwardRef' is used with this component but no 'ref' parameter is set.
  return <button />;
});

Passing

import React from "react";
 
const Example = React.forwardRef<HTMLButtonElement>((props, ref) => {
  return <button ref={ref} />;
});
