익명 함수(Anonymous Function)
var printstuff = function(stuff) {
console.log(stuff);
}
printstuff("stuff");

전역 객체와 타이머
console.log(__filename);
console.log(__dirname);
function printstuff() {
console.log("This was from setTimeout");
}
//setTimeout(printstuff, 5000); 5초후에 실행
setInterval(printstuff, 2000); //2초마다 실행

콜백 함수
• function callback() {
• console.log("Queried the database and delivered data
in 5 seconds");
• }
• console.log("User 1 made a request");
• setTimeout(callback, 5000);
• console.log("User 2 made a request");
• setTimeout(callback, 5000);

모듈1 App.js
• App.js
var athletics = require('./athletics');
athletics.relay();
athletics.longjump();

모듈2 athletics.js
function relay() {
console.log("This is relay function");
}
function longjump() {
console.log("This is longjump function");
}
module.exports.relay = relay;
module.exports.longjump = longjump;

http 모듈로 간단 웹서버 구축
var http = require('http');
http.createServer(function(request, response){
response.writeHead(200, {"Content-Type": "text/plain"});
response.write("Hello World");
response.end();
}).listen(8888);

이벤트 처리
var events = require('events');
var eventEmitter = new events.EventEmitter(); //이벤트를
발생시키는 객체
var ringbell = function() {
console.log(“띵동");
}
eventEmitter.on('doorOpen', ringbell);
eventEmitter.emit('doorOpen');

fs모듈-텍스트파일읽기(비동기처리)
var fs = require('fs');
fs.readFile('input.txt', function(err, data){
if (err) {
console.log(err);
} else {
console.log("Async data is " + data.toString());
}
});

fs모듈-텍스트파일읽기(동기처리)
var data = fs.readFileSync('input.txt');
console.log("Sync data is " + data.toString());
console.log("This is the end");

fs모듈-스트림읽기
var readableStream = fs.createReadStream('input.txt');
var data = '';
readableStream.setEncoding('UTF8');
readableStream.on('data', function(chunk) {
data += chunk;
});
readableStream.on('end', function(){
console.log(data);
});

fs모듈-스트림쓰기
var writeData = "Hello World";
var writableStream = fs.createWriteStream('output.txt');
writableStream.write(writeData, 'UTF8');
writableStream.end();
writableStream.on('finish', function(){
console.log("Write completed");
});

fs모듈-파이프
var readableStream = fs.createReadStream('in.txt');
var writableStream = fs.createWriteStream('out.txt');
readableStream.pipe(writableStream);

Angularjs2 정리
• 일단 환경설정하고
• AngularJS2 QuickStart를 다운/셋팅한다. ==> 여기까지 웹서
핑으로 충분히 가능...
• npm install
• npm start 해서 Hello world 가 뜨는지 확인한다.
