@vtj / node / outputFile

Function: outputFile()

outputFile(file, data, options)

outputFile(file, data, options?): Promise<void>

Almost the same as writeFile (i.e. it overwrites), except that if the parent directory does not exist, it's created.

Parameters

• file: string

• data: string | ArrayBufferView

• options?: WriteFileOptions

Returns

Promise<void>

Example

import * as fs from 'fs-extra'

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

// With a callback:
fs.outputFile(file, 'hello!', err => {
  console.log(err) // => null

  fs.readFile(file, 'utf8', (err, data) => {
    if (err) return console.error(err)
    console.log(data) // => hello!
  })
})

// With Promises:
fs.outputFile(file, 'hello!')
  .then(() => fs.readFile(file, 'utf8'))
  .then(data => {
    console.log(data) // => hello!
  })
  .catch(err => {
    console.error(err)
  })

// With async/await:
async function asyncAwait () {
  try {
    await fs.outputFile(file, 'hello!')

    const data = await fs.readFile(file, 'utf8')

    console.log(data) // => hello!
  } catch (err) {
    console.error(err)
  }
}
