Conditionally controlled component with `value` and `defaultValue` properties

In our project codebase there is an uncontrolled component that allows you to specify an initial value with value property (code examples are simplified just to show an idea):

const CustomInput = ({ value = '', onChange }) => {
  const [uncontrolledValue, setUncontrolledValue] = useState(value);

  const handleChange = (e) => {
    setUncontrolledValue(e.target.value);
    if (onChange) {
      onChange(e.target.value);
    }
  }

  return <input value={uncontrolledValue} onChange={handleChange} />
}

This component is used inside the complex form (other input components in this form are controlled). Resetting the form causes problems with this particular component because it doesn't update the internal value on props change. There is the article that recommends 2 possible solutions:

• rewrite component to be controlled one
• trigger force rerender of the component using key property

IMO there is another option available - make component controlled/uncontrolled depending on existence value property:

const CustomInput = ({ value: controlledValue, defaultValue = '', onChange }) => {
  const [uncontrolledValue, setUncontrolledValue] = useState(defaultValue);
  const isControlled = value !== undefined;
  const value = isControlled ? controlledValue : uncontrolledValue;

  const handleChange = (e) => {
    if (!isControlled) {
      setUncontrolledValue(e.target.value);
    }

    if (onChange) {
      onChange(e.target.value);
    }
  }

  return <input value={value} onChange={handleChange} />
}

This approach allows custom components to act as a standard <input /> element. I saw it in @kentcdodds video lesson and also in some popular libraries sources. But I can't find anything about such an approach in official react documentation. defaultValue is mentioned only here:

• https://reactjs.org/docs/dom-elements.html#value
• https://reactjs.org/docs/uncontrolled-components.html#default-values

Should this approach be added as a recommendation in You Probably Don't Need Derived State or Forms article? If not are there any pitfalls to consider it as bad practice / anti-pattern?

Commencez par la documentation « You Probably Don’t Need Derived State », « Forms » et « Uncontrolled Components » liée dans l’issue. Comparez ses recommandations actuelles avec le controlled/uncontrolled component pattern décrit ici, puis déterminez si une modification de la documentation est justifiée et où elle devrait se trouver.
