Creating a Hook for Accessing the Last Value of a Stream

export const useStream = <E, A>(stream: Stream.Stream<never, E, A>): A | undefined => {
  const [state, setState] = useState<A | undefined>(undefined);
  useEffect(() => {
    const program = pipe(
      stream,
      Stream.runForEach(s => Effect.succeed(setState(s))),
      Stream.runDrain
    )
    Effect.runFork(program)
  })
  return state;
}
