The first result from Google for nodejs worker pool leads to this project: https://github.com/jeffmo/node-worker-pool https://github.com/jeffmo/node-worker-pool The project has only 9 stars on GitHub. While it might be a perfectly fine solution that fixes OP's problem, it certainly doesn't inspire confidence as a battle-tested production-ready library. On the other hand, worker pools and Golang go together very naturally.
