React - Functional error boundaries

Thanks to React hooks you have now happily turned all your classes into functional components.

Wait, all your components? Not quite. There is one thing that can still only be implemented using classes: Error boundaries.

There is just no functional equivalent for componentDidCatch and deriveStateFromError yet.

Proposed solution

export type DeepReadOnly<P> =
  P extends undefined | null | boolean | string | number | Function 
    ? P :
  P extends Array<infer T> 
    ? ReadonlyArray<DeepReadOnly<T>> :
  P extends Map<infer K, infer V> 
    ? ReadonlyMap<DeepReadOnly<K>, DeepReadOnly<V>> :
  P extends Set<infer M> 
    ? ReadonlySet<DeepReadOnly<M>> : 
  { readonly [K in keyof P]: DeepReadOnly<P[K]> }
