The next generation JavaScript doesn't need to dependent on browser, that's just like other programming language. Node.js is it, no need browser, based on fastest V8 JavaScript Engine and provides many APIs for system integration. It can be used to server-side and system, even more purpose.

35. Hello World
快速試看看

36. Hello World! (helloworld.js)
var http = require('http');
http.createServer(function(req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello Worldn');
}).listen(10000);
console.log('Server running at http://localhost:10000/');

37. Run It!
$ node ./helloworld.js
Server running at http://localhost:10000/

38. Cluster Support (cluster.js)
var cluster = require('cluster');
var http = require('http');
var numCPUs = require('os').cpus().length;
if (cluster.isMaster) {
// Fork workers.
for (var i = 0; i < numCPUs; i++) {
cluster.fork();
}
cluster.on('death', function(worker) {
console.log('worker ' + worker.pid + ' died');
});
} else {
// Worker processes have a http server.
http.Server(function(req, res) {
res.writeHead(200);
res.end("hello worldn");
}).listen(8000);
}

39. Run It!
$ node ./cluster.js
Worker 18394 online
Worker 18393 online

40. MongoDB Support (mongodb.js)
var mongodb = require('mongodb');
var server = new mongodb.Server('localhost', 27017);
var db = new mongodb.Db('mydb', server);
/* open db */
db.open(function() {
/* Select 'contact' collection */
db.collection('contact', function(err, collection) {
/* Querying (name == 'Fred Chien') */
collection.find({ name: 'Fred Chien' }, function(err, data) {
console.log('Name: ' + data.name + ', email: ' + data.email);
});
});
});

41. Run It!
$ node ./mongodb.js
name: Fred Chien, email: cfsghost@gmail.com

42. Write a XMPP Server (xmppsrv.js)
var xmpp = require('node-xmpp');
var c2s = new xmpp.C2S({
port: 5222,
domain: 'example.com'
});
c2s.on("authenticate", function(jid, password, client) {
if (password == "12345678") {
client.emit("auth-success", jid);
} else {
client.emit("auth-fail", jid);
}
});
console.log('My XMPP Server was running at localhost:5222');

43. Run It!
$ node ./xmppsrv.js
My XMPP Server was running at localhost:5222

44. Node.js Modules
你可以抓到更多的模組

45. NPM
Node Package Manager

47. 8844+
Large Amount of Module

48. Get Modules with NPM

51. 總結來說...
Anyway...

52. 前端開發者走入後端
一種語言前後都可玩

53. Web開發者
將實現夢想
寫系統程式啦

54. 低階程式讓專業的來
用 Node.js C/C++ Addon 打通硬體和系統的任督二脈

55. JSer 只要專心惡搞
仍然不需要管底層的事

56. 大秘寶就是我們的！
我是海賊王！
