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>
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) })
