Better local require() paths for Node.js

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

Handlebars random JavaScript expression execution, with an IF helper with whatever logical operands and whatever arguments, and few more goodies.
// for detailed comments and demo, see my SO answer here http://stackoverflow.com/questions/8853396/logical-operator-in-a-handlebars-js-if-conditional/21915381#21915381
/* a helper to execute an IF statement with any expression
USAGE:
-- Yes you NEED to properly escape the string literals, or just alternate single and double quotes
-- to access any global function or property you should use window.functionName() instead of just functionName()
-- this example assumes you passed this context to your handlebars template( {name: 'Sam', age: '20' } ), notice age is a string, just for so I can demo parseInt later
<p>
{{#xif " name == 'Sam' && age === '12' " }}
BOOM

offscreen rendering with three.js and headless-gl, in coffee-script

Getting the code

git clone https://gist.github.com/6780d7cc0cabb1b4d6c8.git

Executing the code

$ npm install # maybe npm start will take care of it but just in case
$ npm start && open out.png

Creational Patterns (생성 패턴)

  • Abstract Factory : 구체적인 클래스를 지정하지 않고 관련성을 갖는 객체들의 집합을 생성하거나 서로 독립적인 객체들의 집합을 생성할 수 있는 인터페이스를 제공합니다.
  • Builder : 복합 객체의 생성 과정과 표현 방법을 분리함으로써 동일한 생성 공정이 서로 다른 표현을 만들 수 있게 한다.
  • Factory Method : 객체를 생성하는 인터페이스를 정의하지만, 인스턴스를 만들 클래스의 결정은 서브클래스가 한다. Factory Method 패턴에서는 클래스의 인스턴스를 만드는 시점을 서브클래스로 미룬다.
  • Prototype : 프로토타입의 인스턴스를 이용해서 생성할 객체의 종류를 명세하고 이 프로토타입을 복사해서 새로운 객체를 생성한다.
  • Singleton : 클래스의 인스턴스는 오직 하나임을 보장하며 이 인스턴스에 접근할 수 있는 방법을 제공한다.

Structural Patterns (구조 패턴)

  • Adapter : 클래스의 인터페이스를 클라이언트가 기대하는 다른 인터페이스로 변환한다. Adapter패턴은 호환성이 없는 인터페이스 때문에 함께 사용할 수 없는 클래스를 개조하여 함께 작동하도록 해준다.
  • Bridge : 추상화와 구현을 분리하여 각각을 독립적으로 변형할 수 있게 한다.
