# outputJson(file, object, [options, callback])
Almost the same as [`writeJson`](writeJson.md), except that if the directory does not exist, it's created.
`options` are what you'd pass to [`jsonFile.writeFile()`](https://github.com/jprichardson/node-jsonfile#writefilefilename-options-callback).
**Alias:** `outputJSON()`
- `file` `<String>`
- `object` `<Object>`
- `options` `<Object>`
- `callback` `<Function>`
## Example:
```js
const fs = require('fs-extra')
const file = '/tmp/this/path/does/not/exist/file.json'
fs.outputJson(file, {name: 'JP'}, err => {
console.log(err) // => null
fs.readJson(file, (err, data) => {
if (err) return console.error(err)
console.log(data.name) // => JP
})
})
// With Promises:
fs.outputJson(file, {name: 'JP'})
.then(() => fs.readJson(file))
.then(data => {
console.log(data.name) // => JP
})
.catch(err => {
console.error(err)
})
```
