How to run a module in node js?

Question

JavaScript

Quite a noob in node.js, but I have a question. If I run the node module through the terminal, then it starts the server, and I can go to the web server at the address.
When I write in my app.js var peerflix = require('peerflix');
peerflix is ​​that module. The module works, I get the necessary data, but the web server does not start. Why?

Answer 1

Everyone found the answer, it was necessary to put port: 8888 inside with a comma

Answer 2

Try running it together with the server, since the server is most likely already running, or specify a different port.

Answer 3

Try to run like this:
require('peerflix')()
