Hi I built this little stream processing library so I could write things like;

  const stats = await pipe(
    Nodes.scan({ fields: true }),
    map(generateStats),
    tap(() => count++),
    reduce(mergeGraphStats, {})
  )

and have generateStats and mergeGraphStats be async functions and not have to worry about error handling and pushing more than one object at a time in a read stream. We use it to process billions of events and objects a day. It makes nodejs streams fun to use.

Hope you find it as useful as we do.
