readJson-sync

readJsonSync(file[, options])

读取JSON文件，然后将其解析为对象。

Alias: readJSONSync()

• file <String>
• options <Object> (与 [jsonFile.readFileSync()](https://github.com/jprichardson/node-jsonfile#readfilesyncfilename-options) options一样)

Example:

const fs = require('fs-extra')

const packageObj = fs.readJsonSync('./package.json')
console.log(packageObj.version) // => 2.0.0

---

readJsonSync（）可以接受设置为false的throws选项，如果JSON无效，则不会引发。
Example:

const fs = require('fs-extra')

const file = '/tmp/some-invalid.json'
const data = '{not valid JSON'
fs.writeFileSync(file, data)

const obj = fs.readJsonSync(file, { throws: false })
console.log(obj) // => null
