루비 코리아의 대림 달력도 벌써 4일째입니다. 오늘은 루비 이야기는 아니긴 합니다만, 레일스와 관련있는 이야기를 해볼까 합니다.

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
