stream-chain

Build object-stream pipelines from plain functions, generators, Node streams, or Web streams with automatic backpressure. Version 4.2.3, released March 2025, requires Node >=22. Unlike 'pump' or 'pipeline', every stage can be a sync/async function, generator, or stream — no boilerplate. Ships TypeScript types, zero dependencies, and runs on Node, Bun, and Deno. Includes built-in JSONL parsing/writing. Actively maintained with weekly releases.
