node express worker threads

This repo demonstrates the usage of worker threads to separate part of the app in order not to block the rest of the endpoints

Summary

My goal was to run separate express.Router in the thread and pass request, response objects, but that's not possible due to the limitations of postMessage data.

The first example threads shows offloading the work to the worker.

The second example threads app takes a different approach. It uses worker to spin up a new server on a random assigned port and message back port to the main thread. The main thread is responsible for proxying the request to the child server. It works, so it does not block the main thread.

Test it yourself

Threads

1. Run the server npm run threads
2. Open a separate terminal and run the test npm run test
