[feature request] Array field support about react-use-form-state HOT 2 CLOSED

Hi @melloc01!

I'm not exactly sure what your use case is. If possible, please provide code snippets or a live example to help me better understand this limitations (e.g. codesandbox).

It sounds like .raw() might be what you need here. It was introduced to handle this type of inputs that can have any shape.

For example, if you provide a custom component that controls Requests, you can treat all data related to Requests as a single unit/input in the form state (even though it can be represented as multiple inputs in the UI).

const Requests = ({ onChange, validate, value }) => {
  // maintaining the requests state independently
  const [requests, setRequests] = useState(value);
  const handleChange = useCallback((data) => {
    // update the requests data how like
    onChange(requests); // calling the input's onChange to update formState
  });
  return (
    // logic to render and update the requests fields
  );
}

const Form = () => {
  const [formState, { text, raw }] = useFormState({ requests: [] });
  return (
    <>
      <input {...text('name')} />
      <Requests {...raw('requests')} formState={formState} />
    </>
  );
};

Keep in mind that validation errors can be anything (an object or an array) which will be useful if you want to have multiple errors for a single input.

I hope that helps.
