Export a function in NodeJS module

Question

I have a module in NodeJS which has the following definition:

var express = require('express');
var router = express.Router();

function myFunction(){
    //do some stuff
};

router.get('/url', function(req, res, callback) {   
    var data = myFunction();
    res.render('index', {
        item: data
    });
});

module.exports = router;

I want it to be called in both ways:

HTTP petition:

http://localhost:3090/url

As a function in another module:

var myModule = require('myModule');
var data = myModule.myFunction();

I can access the module by HTTP in the way shown above. However, I don't know how to export myFunction to be used in another module. I have tried the following without any success:

router.myFunction = myFunction;
module.exports = router;

And:

module.exports = router;
module.exports.myFunction = myFunction;

How could I solve this problemn? Thank you very much in advance

Answer 1

you can make these changes

use exports to expose multiple functions

exports.router = router; 
exports.myFunction = myFunction;

for including them both in other file(path to myModule can vary as per your structure) you can now include them as

var routes= require('./myModule').router;
var myfunction = require('./myModule').myFunction;
