Call a “local” function within module.exports from another function in module.exports?

Question

How do you call a function from within another function in a module.exports declaration?

app.js

var bla = require(\'./bla.js\');
console.log(bl         


        

Answer 1

To fix your issue, i have made few changes in bla.js and it is working,

var foo= function (req, res, next) {
  console.log('inside foo');
  return ("foo");
}

var  bar= function(req, res, next) {
  this.foo();
}
module.exports = {bar,foo};

and no modification in app.js

var bla = require('./bla.js');
console.log(bla.bar());

Answer 2

const Service = {
  foo: (a, b) => a + b,
  bar: (a, b) => Service.foo(a, b) * b
}

module.exports = Service
