How to separate a separate function into a managed process?

Question

Node.js

Let's say there is some asynchronous function in a Node.js server application. It is required to allocate it to a managed process so that it is possible to manage the process with requests for routes like /start, /stop, /pause , and the like. How to implement such a moment correctly and with what tools?
Is this approach correct at all?
