Node fs.promises.WriterOptions TypeScript interface | API Reference | Bun

Close the file handle when the writer ends or fails.

Maximum chunk size in bytes for synchronous write operations. Writes larger than this threshold fall back to async I/O. Set this to match the reader's chunkSize for optimal pipeTo() performance.

Maximum number of bytes the writer will accept. Async writes (write(), writev()) that would exceed the limit reject with ERR_OUT_OF_RANGE. Sync writes (writeSync(), writevSync()) return false.

Byte offset to start writing at. When specified, writes use explicit positioning.
