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()

Sync: readJsonSync(), readJSONSync()

Example:

const fs = require('fs-extra')

fs.readJson('./package.json', (err, packageObj) => {
  console.log(packageObj.version) // => 0.1.3
})

---

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

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