What is the correct way to connect modules for node js?

Question

Programming

So that all modules (whether controllers or models) are connected dynamically, as in php. That is, depending on the request. Or so that everyone gathers at startup?

Answer 1

"Or so that everything is assembled at startup"
In the node, lazy loading of libraries is not practiced, as far as I know.
In PHP, this is a necessary measure, because there is most often FastCGI, one request per process at a time, the process is initialized from scratch each time (let's skip dancing with the cache and so on for now).
And the server on the node is long-lived, so there is no problem to spend three seconds at startup to download everything and everything.
