Ensures that the directory exists. If the directory structure does not exist, it is created. Like mkdir -p.

Aliases: mkdirs(), mkdirp()

• dir <String>
• callback <Function>

Example:

const fs = require('fs-extra')

const dir = '/tmp/this/path/does/not/exist'
fs.ensureDir(dir, err => {
  console.log(err) // => null
  // dir has now been created, including the directory it is to be placed in
})

// With Promises:
fs.ensureDir(dir)
.then(() => {
  console.log('success!')
})
.catch(err => {
  console.error(err)
})
