# outputFile(file, data, [options, callback])
|
||
|
|
|
||
|
|
Almost the same as `writeFile` (i.e. it [overwrites](http://pages.citebite.com/v2o5n8l2f5reb)), 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()`](https://nodejs.org/api/fs.html#fs_fs_writefile_file_data_options_callback).
|
||
|
|
|
||
|
|
- `file` `<String>`
|
||
|
|
- `data` `<String> | <Buffer> | <Uint8Array>`
|
||
|
|
- `options` `<Object> | <String>`
|
||
|
|
- `callback` `<Function>`
|
||
|
|
|
||
|
|
## Example:
|
||
|
|
|
||
|
|
```js
|
||
|
|
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)
|
||
|
|
})
|
||
|
|
```
