Node.jsでglob

JavaScript

いわゆるファイル一覧を取得する機能ですね。fs.readdir()でも良いですが、奥深いディレクトリの探索には便利です。
さっそく使ってみます。
glob - npm

$ mkdir my_glob
$ cd my_glob/
$ npm init
$ npm install glob --save

index.js

var glob = require("glob")

options = null;
// options is optional
glob("**/*.js", options, function (er, files) {
	// files is an array of filenames.
	// If the `nonull` option is set, and nothing
	// was found, then files is ["**/*.js"]
	// er is an error object or null.
	console.log(files);
})

optionのstatCacheでキャッシュもできるみたいです。
