Reorder the app.use statement. Earlier you were processing the request before passing through the body-parser.

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var session = require('express-session');
var fs = require('fs');

//body parser before routes
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());

var router = require('./router/main')(app, fs);

var server = app.listen(3000, function(){
   console.log('Express server has started on port 3000');
});

Hope it helped you.
