Server commands (or equivalent) in node.js

Question

I have a server up and running in my digitaldomain droplet. in my server code, I have a function called userCount(); which simply returns the number fo connected users.

I do not want to console.log the number of users on my server, each time someone is connected. This just creates a mess. Instead, I would like to be able to run this command whenever I need to see the "current user count".

How can I make my server in a way that, I will also be able to input commands to it (from the console) whenever it's needed?

What is the best and/or most optimal way of doing this?

How about exporting the relevant function and execute it whenever you feel like it?

droplet.js

...
function userCount() {
    return 42;
}
...
module.exports = {
    userCount: userCount
}

Create a wrapper file:

wrapper.js

var connected = require('./droplet.js');
console.log(connected.userCount());

Execute that file from the command line:

> node wrapper

If you do not want to create an additional file, use the node interface:

> node
console.log(require('./droplet.js').userCount());

I will still wait a bit more for more answers (if there are any) - if not this is already a solution for me.
