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?

Here's some simplified code.

In my app.js, I do the following:

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

and inside of bla.js is

module.exports = {

  foo: function (req, res, next) {
    return ('foo');
  },

  bar: function(req, res, next) {
    this.foo();
  }

}

I'm trying to access the function foo from within the function bar, and I'm getting:

TypeError: Object # has no method 'foo'

If I change this.foo() to just foo() I get:

ReferenceError: foo is not defined

Accepted Answer

I think I got it. I just changed this.foo() to module.exports.foo() and it seems to be working.

If someone has a better or more proper method, please feel free to correct me.

You could declare your functions outside of the module.exports block.

var foo = function (req, res, next) {
  return ('foo');
}

var bar = function (req, res, next) {
  return foo();
}

Then:

module.exports = {
  foo: foo,
  bar: bar
}
