printing thread id

[Pawel Por]

Hi

How can I print thread id in node js ?
I mean thread ID (TID) not process ID (PID).

thanks for answer

I think that Node.js don't have threads, so no TID...

but "ps" linux command shows that my node application consumes 2 threads.

node.js does have threads under the hood, i.e. fs calles are processed by a threadpool. there is however no public api for thread id detection. only way i could think of currently is to make a system call via shell and parse it out, like 'ps -M | grep '+ process.pid

Yeah, but your javascript always runs in the main process, which has a
tid === pid.

What exactly are you looking for? Just poking around out of curiosity?
In that case, check out the libuv headers, the in-header docs explain
or imply a lot about node.

You can have fibers instead. They are close to threads, and you can assign id to it or use fiber local storage
