Worker Thread

Definitions

1. In Node.js, a worker_threads module API that spawns additional V8 isolates running in separate OS threads, sharing memory via SharedArrayBuffer and communicating via message ports — enabling true parallelism for CPU-intensive work without forking separate processes.

   In plain English: A way to run heavy computations on a separate thread in Node.js so the main application stays fast and responsive.

   Example: "We moved the PDF rendering into a worker thread so it doesn't block the event loop and tank API response times."
