+
+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](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse).
+  - `throws` (`boolean`, default: `true`). If `JSON.parse` throws an error, pass this error to the callback.
+  If `false`, returns `null` for the object.
+
+
+```js
+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](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse).
+- `throws` (`boolean`, default: `true`). If an error is encountered reading or parsing the file, throw the error. If `false`, returns `null` for the object.
+
+```js
+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](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify). Can also pass in `spaces`.
+
+
+```js
+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:**
+
+```js
+var jsonfile = require('jsonfile')
+
+var file = '/tmp/data.json'
+var obj = {name: 'JP'}
+
+jsonfile.writeFile(file, obj, {spaces: 2}, function(err) {
+  console.error(err)
+})
+```
+
+**appending to an existing JSON file:**
+
+You can use `fs.writeFile` option `{flag: 'a'}` to achieve this.
+
+```js
+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](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify). Can also pass in `spaces`.
+
+```js
+var jsonfile = require('jsonfile')
+
+var file = '/tmp/data.json'
+var obj = {name: 'JP'}
+
+jsonfile.writeFileSync(file, obj)
+```
+
+**formatting with spaces:**
+
+```js
+var jsonfile = require('jsonfile')
+
+var file = '/tmp/data.json'
+var obj = {name: 'JP'}
+
+jsonfile.writeFileSync(file, obj, {spaces: 2})
+```
+
+**appending to an existing JSON file:**
+
+You can use `fs.writeFileSync` option `{flag: 'a'}` to achieve this.
+
+```js
+var jsonfile = require('jsonfile')
+
+var file = '/tmp/mayAlreadyExistedData.json'
+var obj = {name: 'JP'}
+
+jsonfile.writeFileSync(file, obj, {flag: 'a'})
+```
+
+### spaces
+
+Global configuration to set spaces to indent JSON files.
+
+**default:** `null`
+
+```js
+var jsonfile = require('jsonfile')
+
+jsonfile.spaces = 4
+
+var file = '/tmp/data.json'
+var obj = {name: 'JP'}
+
+// json file has four space indenting now
+jsonfile.writeFile(file, obj, function (err) {
+  console.error(err)
+})
+```
+
+Note, it's bound to `this.spaces`. So, if you do this:
+
+```js
+var myObj = {}
+myObj.writeJsonSync = jsonfile.writeFileSync
+// => this.spaces = null
+```
+
+Could do the following:
+
+```js
+var jsonfile = require('jsonfile')
+jsonfile.spaces = 4
+jsonfile.writeFileSync(file, obj) // will have 4 spaces indentation
+
+var myCrazyObj = {spaces: 32}
+myCrazyObj.writeJsonSync = jsonfile.writeFileSync
+myCrazyObj.writeJsonSync(file, obj) // will have 32 space indentation
+myCrazyObj.writeJsonSync(file, obj, {spaces: 2}) // will have only 2
+```
