Can you clarify "main thread"? Do you have a code example? Asking as Node is single threaded.

Thanks

Most likely using the cluster module and your favorite IPC module.

That or https://nodejs.org/api/worker_threads.html#worker-threads

My go-to method of inter-process communication in Node without using any third party modules is to just use process.send[1] to a send a message to the main thread, and then have it forward messages to the workers in the cluster, which you can listen for using the message event [2].

Using cluster and worker threads. The code is here, but completely undocumented, as I’ve been side tracked by a few other things[0]. I’m currently looking into porting that project to Bun, so it’s possibly dead in its current form.

I was planning on turning that into a library, but Bun nerd sniped me.

You need the “hey” tool to run the benchmarks[1] the way that I was running them.
