# ensureDir(dir, callback) Ensures that the directory exists. If the directory structure does not exist, it is created. Like `mkdir -p`. **Aliases:** `mkdirs()`, `mkdirp()` **Sync:** `ensureDirSync()`, `mkdirsSync()`, `mkdirpSync()` ## Example: ```js var fs = require('fs-extra') var dir = '/tmp/this/path/does/not/exist' fs.ensureDir(dir, function (err) { console.log(err) // => null // dir has now been created, including the directory it is to be placed in }) ```
