findDOMNode is deprecated in StrictMode

[palagonKevo]

I've been facing this warning for a lot of time. Everything works fine, but it keeps saying that it's deprecated. I've been diving into the code to find the current issue and I found out that the problem has to be with the react-draggable dependency that it's used within this project.

To be more precise, the file that is having issues with is /src/components/RangeBox.tsx., in which the draggable library is used. I've been also looking at the library's code in order to find a solution and I found out that in their changelog files they have already contemplated this issue, and they have provided a solution to it.

Down is the text that they have written about this:

4.4.0 (May 12, 2020)

• Add nodeRef:
  • If running in React Strict mode, ReactDOM.findDOMNode() is deprecated. Unfortunately, in order for <Draggable> to work properly, we need raw access to the underlying DOM node. If you want to avoid the warning, pass a nodeRef as in this example:

    function MyComponent() {
    const nodeRef = React.useRef(null);
    return (
    <Draggable nodeRef={nodeRef}>
      <div ref={nodeRef}>Example Target</div>
    </Draggable>
    );
    }

Would it be possible to fix this? The solution itself is quite easy as it only requires adding a prop with the ref variable as stated in the example provided by the developers.

Thanks in advance.
