Get Started

First Step

---

Write a own middleware, then package it to be a courlan module in the specific directory you want.

middlewares/login_required.js

module.exports = {
    name: 'LoginRequired',
    middleware: function(req, res, next) {

        // Checks whether user is logged on or not
        if (req.session.logined) {
            next();
            return;
        }
  
        // Forbidden
        res.status(404);
        res.send('404 Not Found');
        res.end();
    }
    
}

Second Step

---

Load all middlewares with courlan when initializing express application.

app.js

var express = require('express');
var courlan = require('courlan');

var app = express();

courlan(__dirname + '/middleware', function() {

    app.configure(function() {
        // Do stuffs
    });

    app.listen(8000);
});

Final Step

---

Using your own middleware in anywhere.

var Middleware = require('courlan');

app.get('/test', Middleware.LoginRequired, function(req, res) {

    res.end('Success');
});
