readJson(file, [options, callback])

Reads a JSON file and then parses it into an object. `options` are the same that you'd pass to `jsonFile.readFile`.

Alias: `readJSON()`

- `file` `<String>`
- `options` `<Object>`
- `callback` `<Function>`

# Example:

const fs = require('fs-extra')
fs.readJson('./package.json', (err, packageObj) => {
if (err) console.error(err)
console.log(packageObj.version) // => 0.1.3
})
// Promise Usage
fs.readJson('./package.json')
.then(packageObj => {
console.log(packageObj.version) // => 0.1.3
})
.catch(err => {
console.error(err)
})

`readJson()` can take a `throws` option set to `false` and it won't throw if the JSON is invalid. Example:

const fs = require('fs-extra')
const file = '/tmp/some-invalid.json'
const data = '{not valid JSON'
fs.writeFileSync(file, data)
fs.readJson(file, { throws: false }, (err, obj) => {
if (err) console.error(err)
console.log(obj) // => null
})
// Promise Usage
fs.readJson(file, { throws: false })
.then(obj => {
console.log(obj) // => null
})
.catch(err => {
console.error(err) // Not called
})
