Node.js TypeError: object is not a function. What is the issue here?

I am new to node.js and I have the following exported function

LiveEvent.js

function liveEvent(connection) { 
   this.db = connection.
}

liveEvent.prototype.someMethod = function() { } 

module.exports = liveEvent;

Now in another file

Enduser.js

var LiveEvent = require('./LiveEvent');

When i try to do the following i get TypeError: object is not a function

var liveEvent = new LiveEvent(connection);

What am i doing wrong ? Any suggestions appreciated.

You don't need the function keyword to create a prototype method.

function liveEvent(connection) { 
   this.db = connection;
}

liveEvent.prototype.someMethod = function() { } 

module.exports = liveEvent;
