import * as fs from 'fs-extra'

const file = '/tmp/this/path/does/not/exist/file.txt'

// With a callback:
fs.ensureFile(file, err => {
  console.log(err) // => null
  // file has now been created, including the directory it is to be placed in
})

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

// With async/await:
async function asyncAwait () {
  try {
    await fs.ensureFile(file)
    console.log('success!')
  } catch (err) {

  }
