nodejs require statement issue

I'm new to nodejs. I have the following files and code:

// file: myfunc.js
function myfunc() { return "myfunc()"; }
exports = myfunc;

and

// file: index.js
var mf = require("./myfunc");
var mfunc = mf();
console.log(mfunc);

When I run node index.js from command line, I get the error

var mfunc = mf()
            ^
TypeError: Object is not a function

Why do I get this error? I saw someone else's code which I paste below and I tried to follow the same approach of trying to get require() to return a function instead of an object.

// file: index.js from another app
var express = require('express');
var app = express();

How come require('express') can return a function but require('./myfunc') can't return a function?

It should be...

module.exports = myfunc;

... instead. Quoting the doc:

If you want the root of your module's export to be a function (such as a constructor) or if you want to export a complete object in one assignment instead of building it one property at a time, assign it to module.exports instead of exports.
