outputFile(file, data, [options, callback])

Almost the same as `writeFile` (i.e. it overwrites), except that if the parent directory does not exist, it's created. `file` must be a file path (a buffer or a file descriptor is not allowed). `options` are what you'd pass to `fs.writeFile()`.

- `file` `<String>`
- `data` `<String> | <Buffer> | <Uint8Array>`
- `options` `<Object> | <String>`
- `callback` `<Function>`

# Example:

const fs = require('fs-extra')
const file = '/tmp/this/path/does/not/exist/file.txt'
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)
})
