calling exports.start in same js file node.js

Hi this is my method in a node js file:

exports.start = function() {
    console.log(' in start of sender.js');
});

How can I call this method in the same js file? I tried calling start() and exports.start() but not successful.

Use this code:

var start = exports.start = function() {
   console.log(' in start of sender.js');
});

or

function start() {
   console.log(' in start of sender.js');
});

exports.start = start;

//you can call start();

exports.start = function(){
    console.log('testing...')
}

You can call this method like this

    exports.start();

You can call the exported function like this

module.exports.functionName(arguments);

Your named function:

var start = function() {
   console.log(' in start of sender.js');
});

And later export object:

module.exports = {start : start}

So you can call start() in the same js file
