outputJson(file, object, [options, callback])

Almost the same as writeJson, except that if the directory does not exist, it’s created.

Alias: outputJSON()

  • file <String>
  • object <Object>
  • options <Object>
    • spaces <Number|String> Number of spaces to indent; or a string to use for indentation (i.e. pass '\t' for tab indentation). See the docs for more info.
    • EOL <String> Set EOL character. Default is \n.
    • replacer JSON replacer
    • Also accepts fs.writeFile options
  • callback <Function>

Example:

  1. const fs = require('fs-extra')
  2. const file = '/tmp/this/path/does/not/exist/file.json'
  3. fs.outputJson(file, {name: 'JP'}, err => {
  4. console.log(err) // => null
  5. fs.readJson(file, (err, data) => {
  6. if (err) return console.error(err)
  7. console.log(data.name) // => JP
  8. })
  9. })
  10. // With Promises:
  11. fs.outputJson(file, {name: 'JP'})
  12. .then(() => fs.readJson(file))
  13. .then(data => {
  14. console.log(data.name) // => JP
  15. })
  16. .catch(err => {
  17. console.error(err)
  18. })
