Add react hooks support

Hi! Thank you for your package

I’m wondering, are there any plans to support React hooks? Something like

const {width, height} = useResizeDetector(ref);

I believe it can be useful nowadays

Great push, @LosYear 😃

I also think it will be a good feature for the library. I’ll try to work on it this month

Typescript support? Setting ref={ref} in typescripts it says that

Type ‘MutableRefObject<Element | undefined>’ is not assignable to type ‘string | ((instance: HTMLDivElement | null) => void) | RefObject<HTMLDivElement> | null | undefined’. Type ‘MutableRefObject<Element | undefined>’ is not assignable to type ‘RefObject<HTMLDivElement>’. Types of property ‘current’ are incompatible. Type ‘Element | undefined’ is not assignable to type ‘HTMLDivElement | null’. Type ‘undefined’ is not assignable to type ‘HTMLDivElement | null’.
