Webpack을 사용한 현대적 자바스크립트 개발 시작하기

Webpack은 @sokra(Tobias Koppers)와 컨트리뷰터들이 구현하고 있는 자바스크립트 기반의 모듈 번들러와 그를 받쳐주는 라이브러리(webpack/lib), 그리고 에코시스템(플러그인, 로더)들을 의미합니다.

스포카에서는 2014년 12월부터 React.js를 전면 도입하여 새 버젼의 적립 애플리케이션을 제작하고 있습니다. 이 개발 과정을 뒷받침해주고 있는 가장 중요한 도구를 말하라고 한다면 두말할 것도 없이 Webpack일 것입니다.

사실 Node.js나 파이썬 같은 환경에서 개발을 해본 사람들에게는 모듈이라는 개념이 익숙하지만, 웹 프론트엔드 개발자에게 모듈이라는 개념은 조금 낯설 수 있는 것이 사실입니다. require.js와 같은 AMD 시스템 또는 Browserify같은 도구를 이용해 본 경험이 없다면 말이죠.

모듈이라는 것은 굉장히 중요합니다. 모듈 시스템을 갖춘 환경에서 일해본 사람은 어떤 이유에서든 그 중요성에 모두 공감할 것입니다. 하지만 웹에는 표준적인 개념의 모듈이라는 것이 없었습니다 (사실 아직도 제대로 된 것은 딱히 없습니다만). 그렇기 때문에 자바스크립트 모듈을 사용하기 위해서는 모듈을 다룰 수 있는 시스템 (RequireJS, CommonJS 등)이 필요하고, 모듈들의 내용과 export들을 이해하고 원하는 형태로 변형할 수 있는 도구가 필요합니다. Webpack과 Browserify는 이런 것을

Why are black boxes so hard to reuse?

I think our field will go through a revolution. We will fundamentally change the way we think about and use abstraction in the engineering of software.

The goal of this talk is to summarize the need for and the basic nature of this abstraction framework.

The change is not new problems or new systems, but a new way of thinking about existing problems and existing systems.

A Brief Introduction to Fabric

Fabric is a deployment management framework written in Python which makes remotely managing multiple servers incredibly easy. If you've ever had to issue a change to a group servers, this should look pretty familiar:

for s in $(cat servers.txt); do ssh $s service httpd graceful; done

Fabric improves on this process by providing a suite of functions to run commands on the servers, as well as a number of other features which just aren't possible in a simple for loop. While a working knowledge of Python is helpful when using Fabric, it certainly isn't necessary. This tutorial will cover the steps necessary to get started with the framework and introduce how it can be used to improve on administering groups of servers.
