We wrap the Search component in the forwardRef function, which does the ref forwarding for us.,This doesn’t work though, and a type error is raised when we reference ref on the Search component. 😞,For this to work, we need to forward the ref to the App component. We can acheive this with forwardRef from React:

function Search() {
  return <input type="search" />;
}

I have problem with forwardRef in Typescript in ReactJS.,My goal is to wrap bootstrap FormControl and provide some simple logic for now on it then build on it. I know that FormControl forward its reference to the input element.,Now how can I forward a reference in my component to this reference that FormControl is forwarding. My code now looks like that:

The forwardRef API is pretty straight-forward. You wrap your component in a function call, with is passed props and the forwarded ref, and you're then supposed to return your component. Here's a simple example in JavaScript: ,You can then use this component like ref was a regular prop: ,The correct way to type a forwardRef-wrapped component is:

const Button = React.forwardRef(
  (props, forwardedRef) => (
    <button {...props} ref={forwardedRef} />
  )
);

This is especially useful if you wrap basic components or leafs in proxy components, but want to use the ref property just like you’re used to:,This is one of these cases, here I know that my original component accepts generic props!,So without the additional properties, it should be possible to use higher-order function type inference!

This is especially useful if you wrap basic components or leafs in proxy components, but want to use the ref property just like you’re used to:

const Button = React.forwardRef((props, ref) => (  <button type="button" {...props} ref={ref}>    {props.children}  </button>));// Usage: You can use your proxy just like you use// a regular button!const reference = React.createRef();<Button className="primary" ref={reference}>Hello</Button>

We pass our ref down to <FancyButton ref={ref}> by specifying it as a JSX attribute.,We forward this ref argument down to <button ref={ref}> by specifying it as a JSX attribute.,React passes the ref to the (props, ref) => ... function inside forwardRef as a second argument.

function FancyButton(props) {
  return (
    <button className="FancyButton">
      {props.children}
    </button>
  );
}

You may, however, need to wrap a component in order to enhance it, which can conflict with the muiName solution. If you wrap a component, verify if that component has this static property set.,Be aware that you will still get this warning for lazy and memo components if their wrapped component can't hold a ref.,This section covers caveats when using a custom component as children or for the component prop.

Let's see an example:

const WrappedIcon = props => <Icon {...props} />;
WrappedIcon.muiName = Icon.muiName;

React forwardRef is a method that allows parent components pass down (i.e., “forward”) refs to their children. Using forwardRef in React gives the child component a reference to a DOM element created by its parent component. This then allows the child to read and modify that element anywhere it is being used.,There are many refs in React that can be pointed to using forwardRef. As seen in the official React documentation, we can use refs for a variety of tasks:,In general good information, but about forwardRef info, very disappointing. It is almost a copy/paste from the react documentation. I was looking to understand forwardRef better.
