Node.js API to spawn off a call to another API

I created a Node.js API. When this API gets called I return to the caller fairly quickly. Which is good.

But now I also want API to call or launch an different API or function or something that will go off and run on it's own. Kind of like calling a child process with child.unref(). In fact, I would use child.spawn() but I don't see how to have spawn() call another API. Maybe that alone would be my answer?

Of this other process, I don't care if it crashes or finishes without error. So it doesn't need to be attached to anything. But if it does remain attached to the Node.js console then icing on the cake.

I'm still thinking about how to identify & what to do if the spawn somehow gets caught up in running a really long time. But ready to cross that part of this yet.

Your thoughts on what I might be able to do?
