Adding external javascript files on node.js

I have a node server and I want to add an external .js file (say something.js). I have this code for now:

var st = require('./js/something');

Where something.js is the JavaScript file inside a /js/ folder. The server compiles and run, but when I try to use functions defined in something.js node tells me they are not defined.

I also tried to run them using like st.s() but nothing happens and I have an error saying that the object has no method s().

Can anyone help me?

Thanks,

EDIT:

logging st gives {} (I obtain it from console.log(JSON.stringify(st)). Also doing console.log(st) gives {} as result.

The content of something.js is just a bunch of functions defined like this

function s() {
    alert("s");
}

function t() {
    alert("t");
}

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

Node.js uses the CommonJS module format. Essentially values that are attached to the exports object are available to users of the module. So if you are using a module like this

var st = require('./js/something');
st.s();
st.t();

Your module has to export those functions. So you need to attach them to the exports object.

exports.s = function () {
    console.log("s");
}

exports.t = function () {
    console.log("t");
}

Note: Use and implement solution 1 because this method fully tested our system.
Thank you 🙂
