Tim van der Lippe e4974ddc4c Remove whitespace at the end of the package.json lines

json.dump appears to add extraneous spaces before newline characters. By
specifying the separators option, we can remove these whitespaces,
reducing the diff noise. Solution taken from
https://stackoverflow.com/questions/16311562/python-json-without-whitespaces

DISABLE_THIRD_PARTY_CHECK=Fix whitespace in node_modules

Node.js - jsonfile

Easily read/write JSON files.

Why?

Writing JSON.stringify() and then fs.writeFile() and JSON.parse() with fs.readFile() enclosed in try/catch blocks became annoying.

Installation

npm install --save jsonfile

API

readFile(filename, [options], callback)

options (object, default undefined): Pass in any fs.readFile options or set reviver for a JSON reviver.

throws (boolean, default: true). If JSON.parse throws an error, pass this error to the callback. If false, returns null for the object.

var jsonfile = require('jsonfile')
var file = '/tmp/data.json'
jsonfile.readFile(file, function(err, obj) {
  console.dir(obj)
})

readFileSync(filename, [options])

options (object, default undefined): Pass in any fs.readFileSync options or set reviver for a JSON reviver.

throws (boolean, default: true). If an error is encountered reading or parsing the file, throw the error. If false, returns null for the object.

var jsonfile = require('jsonfile')
var file = '/tmp/data.json'

console.dir(jsonfile.readFileSync(file))

writeFile(filename, obj, [options], callback)

options: Pass in any fs.writeFile options or set replacer for a JSON replacer. Can also pass in spaces and override EOL string.

var jsonfile = require('jsonfile')

var file = '/tmp/data.json'
var obj = {name: 'JP'}

jsonfile.writeFile(file, obj, function (err) {
  console.error(err)
})

formatting with spaces:

var jsonfile = require('jsonfile')

var file = '/tmp/data.json'
var obj = {name: 'JP'}

jsonfile.writeFile(file, obj, {spaces: 2}, function(err) {
  console.error(err)
})

overriding EOL:

var jsonfile = require('jsonfile')

var file = '/tmp/data.json'
var obj = {name: 'JP'}

jsonfile.writeFile(file, obj, {spaces: 2, EOL: '\r\n'}, function(err) {
  console.error(err)
})

appending to an existing JSON file:

You can use fs.writeFile option {flag: 'a'} to achieve this.

var jsonfile = require('jsonfile')

var file = '/tmp/mayAlreadyExistedData.json'
var obj = {name: 'JP'}

jsonfile.writeFile(file, obj, {flag: 'a'}, function (err) {
  console.error(err)
})

writeFileSync(filename, obj, [options])

options: Pass in any fs.writeFileSync options or set replacer for a JSON replacer. Can also pass in spaces and override EOL string.

var jsonfile = require('jsonfile')

var file = '/tmp/data.json'
var obj = {name: 'JP'}

jsonfile.writeFileSync(file, obj)

formatting with spaces:

var jsonfile = require('jsonfile')

var file = '/tmp/data.json'
var obj = {name: 'JP'}

jsonfile.writeFileSync(file, obj, {spaces: 2})

overriding EOL:

var jsonfile = require('jsonfile')

var file = '/tmp/data.json'
var obj = {name: 'JP'}

jsonfile.writeFileSync(file, obj, {spaces: 2, EOL: '\r\n'})

appending to an existing JSON file:

You can use fs.writeFileSync option {flag: 'a'} to achieve this.

var jsonfile = require('jsonfile')

var file = '/tmp/mayAlreadyExistedData.json'
var obj = {name: 'JP'}

jsonfile.writeFileSync(file, obj, {flag: 'a'})
