MEAN Stack using Angular 2 and Universal

Used external mongoDB server but the same way you can use local one. Just change in /routes/tosos.js to local MongoDB server

var db = mongojs('mongodb://admin:admin123@ds037827.mongolab.com:37827/ng2todoapp', ['todos']);

This project now in stage of part two To start project after git clone use

npm install -g universal-cli
npm install
bower install
ung serve

For production

ung build --prod
node ./dist/server.bundle.js

Part One

Install packages

npm install -g angular-cli
ng new todoApp --skip-git true
ng set defaults.styleExt scss

test ng2 app is working

ng serve

Navigate to http://localhost:4200/

should see app works!
Install packages for server side:

npm install --save body-parser cookie-parser ejs express mongojs morgan path

Create Express server with routes

//server.js

var express = require('express');
var path = require('path');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');

var index = require('./routes/index');
var todos = require('./routes/todos');

var app = express();

app.set('views', path.join(__dirname, './public/'));
app.set('view engine', 'ejs');
app.engine('html', require('ejs').renderFile);
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
    extended: false
}));

app.use(cookieParser());
app.use(express.static(path.join(__dirname, './public/')));
app.use('/', index);
app.use('/api/v1/', todos);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
    var err = new Error('Not Found');
    err.status = 404;
    next(err);
});

var server = app.listen(3000, function() {
    var host = 'localhost';
    var port = server.address().port;
    console.log('App listening at http://%s:%s', host, port);
});

module.exports = app;

//routes/index.js

var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
    res.render('index.html');
});
module.exports = router;

//routes/todos.js

var express = require('express');

var mongojs = require('mongojs');
var db = mongojs('mongodb://admin:admin123@ds037827.mongolab.com:37827/ng2todoapp', ['todos']);
/* GET All Todos */

    });
});
/* POST/SAVE a Todo */

    if (!todo.text || !(todo.isCompleted + '')) {
        res.status(400);
        res.json({
            "error": "Invalid Data"
        });
    } else {
        db.todos.save(todo, function(err, result) {
            if (err) {
                res.send(err);
            } else {
                res.json(result);
            }
        })
    }
});
/* PUT/UPDATE a Todo */
router.put('/todo/:id', function(req, res, next) {
    var todo = req.body;
    var updObj = {};
    if (todo.isCompleted) {
        updObj.isCompleted = todo.isCompleted;
    }
    if (todo.text) {
        updObj.text = todo.text;
    }
    if (!updObj) {
        res.status(400);
        res.json({
            "error": "Invalid Data"
        });
    } else {
        db.todos.update({
            _id: mongojs.ObjectId(req.params.id)
        }, updObj, {}, function(err, result) {
            if (err) {
                res.send(err);
            } else {
                res.json(result);
            }
        });
    }
});
/* DELETE a Todo */
router.delete('/todo/:id', function(req, res) {

now in project root

ng build -prod --output-path ./public
node server

Navigate to http://localhost:3000 Finish of part One :)

Part Two: Universal

Just check code becouse App is fully revrited based on part one tutorial Shortest way use this https://github.com/devCrossNet/angular-cli#support-for-server-side-rendering This project compatible with ung (Universal CLI) To run after git clone

npm install -g universal-cli
npm install 
bower install
ung serve

Will update README on request via GitHub issue If you give me star I will be more happy to do work :)
