안녕하세요. 사원사업부의 마루야마@h13i32maru입니다. 최근의 Web 프론트엔드의 변화는 매우 격렬해서, 조금 눈을 땐 사이에 점점 새로운 것이 나오고 있더라구요. 그런 격렬한 변화중 하나가 ES6이라는 차세대 JavaScript의 사양입니다. 이 ES6는 현재 재정중으로 집필시점에서는 Draft Rev31이 공개되어있습니다.
JavaScript는 ECMAScript(ECMA262)라는 사양을 기반으로 구현되어있습니다. 현재 모던한 Web 브라우저는 ECMAScript 5.1th Edition을 기반으로 한 JavaScript실행 엔진을 탑재하고 있습니다. 그리고 다음 버전인 ECMAScript 6th Edition이 현재 재정중으로, 약칭으로 ES6이라는 명칭이 사용되고 있습니다.

Download Flutter SDK, extract the "Flutter" folder and put somewhere on your machine https://flutter.dev/docs/get-started/install
Add path for 'location/flutter/bin'
| // node: v0.10.21 | |
| // request: 2.27.0 | |
| var request = require('request'); | |
| var fs = require('fs'); | |
| var r = request.post("http://server.com:3000/"); | |
| // See http://nodejs.org/api/stream.html#stream_new_stream_readable_options | |
| // for more information about the highWaterMark | |
| // Basically, this will make the stream emit smaller chunks of data (ie. more precise upload state) | |
| var upload = fs.createReadStream('f.jpg', { highWaterMark: 500 }); |
For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.
Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.
You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
