Scaling Node.js and unblocking the Event Loop
summary
Claims that moving CPU work out of the main thread prevents cases like a process stuck on 200k rows by loading modules into another process via sr and using Node core tools like child_process and worker threads. Advises measurement with block-pet, shows chunking arrays by hundreds and using streams instead of tight while loops, explains serverless and load‑balancing options, and demos a 5s blocking loop running in a child process so the main event loop keeps responding.
