Issues using writeJson with Babel

[donaldpipowitch]

If I writeJson my output isn't formatted. I think this is a problem with jsonfile? I use the most recent version.

console.log(fs.jsonfile); // {}
fs.jsonfile.spaces = 2;
console.log(fs.jsonfile); // {} ... I think this should be { spaces: 2 }

What is the output that you get from this snippet?

var fs = require('fs-extra')

var data = { name: 'jp' }
fs.jsonfile.spaces = 4
fs.writeJson('/tmp/test.json', data, function (err) {
  if (err) console.error(err)
  var text = fs.readFileSync('/tmp/test.json', 'utf8')
  console.log(text)
})

Well... the output is correct:

{
    "name": "jp"
}

To be honest, I really use fs-extra-promise not vanilla fs-extra. So I changed your example after the first test to this:

var fs = require('fs-extra-promise')

var data = { name: 'jp' }
fs.jsonfile.spaces = 4
fs.writeJsonAync('/tmp/test.json', data).then(function () {
  var text = fs.readFileSync('/tmp/test.json', 'utf8')
  console.log(text)
})

And... the output is still correct:

{
    "name": "jp"
}

Now I was really confused... why doesn't it work for me outside of this small test case? I use fs-extra-promise instead of fs-extra, because I use Babel. So I made a third test:

import fs, { writeJsonAsync, readFileSync} from 'fs-extra-promise';

var data = { name: 'jp' }
fs.jsonfile.spaces = 4
writeJsonAync('/tmp/test.json', data).then(function () {
  var text = freadFileSync('/tmp/test.json', 'utf8')
  console.log(text)
})

And... BAM... this is the error:

{"name":"jp"}

The same happens if I use writeJson with fs-extra instead of the promisified version.

So... if Babel got the spec right (cc @sebmck) and doesn't have a bug, I'd say this is a bug on fs-extras side. As ES6 modules are now standardized (just not implemented yet in native Node) I'd expect import { writeJson } from 'fs-extra'; to work like var writeJson = require('fs-extra').writeJson.

@jprichardson Any ideas? I've got other more pressing things ATM.

This is over a year old. If there is still some issue with the latest versions and Babel6, feel free to reopen @donaldpipowitch.
