Node.js ファイルを書き込みする際にフォルダを作成する

Last updated at Posted at 2015-06-09

ファイルを作成する際にフォルダがなかった場合、自動的に作ってほしいですよね。
そのお手軽なソリューションです。

writefile.js

var mkdirp = require("mkdirp")
var fs = require("fs")
var getDirName = require("path").dirname
function writeFile (path, contents, cb) {
  mkdirp(getDirName(path), function (err) {
    if (err) return cb(err)
    fs.writeFile(path, contents, cb)
  })
}

writefile("c:/Users/hoge/hoge1/foga2/foo.txt","foo",function(err){
        if(err) throw err;
});

結果"c:/Users/hoge/hoge1/foga2/foo.txt"が作成されますフォルダが無ければすべて再帰的に作成されます

このとおりmkdirpを使えば簡単です。
mkdirpは

npm install mkdirp

としてインストールすればOKです。

以上。
