//LOG
var logDir = path.join(__dirname, 'logs');

//APP CONFIG
//====================================
//configure app to use BodyParser();
//this will let us get the data form a POST

//log module
app.use(morgan('short'));

}));

var port = process.env.PORT || 8091;  //set port

app.use(express.static('app'));
//REGISTER OUR ROUTES
//===================================
app.use('/', indexRouter);

//ERROR HANDLE
app.use(function(req, res, next){
    var err = new Error('not Found');
    err.status = 404;
    res.status(404).send(err);
});

    res.status(500).send('Something broke!');
});

//START THE SERVER
