bulk‑write‑stream is a tiny Node.js utility that creates a writable stream which batches all data buffered up to the stream’s `highWaterMark` and passes the whole batch to a user‑provided `write` (or `flush`) function via the newer `writev` API. It’s aimed at developers who need efficient bulk‑write handling—especially in object mode—when building high‑throughput Node streams or custom storage adapters.
