8. Page 8 Socket.IO enables real-time bidirectional event-based communication. It works

   on every platform, browser or device, focusing equally on reliability and speed. USED BY EVERYONE From Microsoft Office, Yammer, Zendesk, Trello... to hackathon winners and little startups. http://socket.io/ Node.js – from the Beginning socket.io 22-Apr-16

   = require('http').createServer( app ).listen( config.port ), io = require('socket.io').listen( server ), numConn = 0; ... Node.js – from the Beginning socket.io 22-Apr-16

10. Page 10 ... io.on( 'connection', function(socket) { numConn += 1;

    console.log( "connected", numConn ); // event for login from socket socket.on( "login", function ( name ) { socket.nickname = name; }); ... socket.on( "disconnect", function() { numConn -= 1; console.log( "disconnect", numConn ); }); }); Node.js – from the Beginning socket.io 22-Apr-16

11. Page 11 ... // socket sends message socket.on( "sendMessage", function(

    msg ) { console.log( "send message", numConn, socket.nickname, msg ); // broadcast message to all subscribed sockets socket.broadcast.emit( "newMessage", { name: socket.nickname, msg: msg } ); }); ... Node.js – from the Beginning socket.io 22-Apr-16

22. Page 22 The web framework of your dreams Built for

    developers by a giant squid. Sails makes it easy to build custom, enterprise-grade Node.js apps. It is designed to emulate the familiar MVC pattern of frameworks like Ruby on Rails, but with support for the requirements of modern apps. http://sailsjs.org/ Node.js – from the Beginning SailsJS 22-Apr-16

25. Page 25 next generation web framework for node.js Koa is

    a new web framework designed by the team behind Express, which aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. http://koajs.com/ Node.js – from the Beginning Koa 22-Apr-16

26. Page 26 var koa = require('koa'), app = koa(); app.use(

    function *(next){ var start = new Date; yield next; var ms = new Date - start; this.set('Response-Time', ms + 'ms'); }); app.use( function *(){ this.body = 'Hello World'; }); app.listen( 80 ); Node.js – from the Beginning Koa (1.x) 22-Apr-16

27. Page 27 var Koa = require('koa'), app = new Koa(),

    co = require('co'); app.use( co.wrap( function *( ctx, next){ const start = new Date; yield next(); var ms = new Date - start; console.log( 'Response-Time', ms ); })); app.use( ctx => { ctx.body = 'Hello World'; }); app.listen( 80 ); Node.js – from the Beginning Koa (2.x) 22-Apr-16

32. Page 32 Disadvantages Even though ThinkJS has many advantages, it

    has also a few disadvantages too, for example: •  ThinkJS is a relatively new framework, the community is not strong enough. •  ThinkJS is short of large scale applications. Node.js – from the Beginning ThinkJS 22-Apr-16
