Async and sync ways to read files with FS in node.

nodeReadFile

var fs = require('fs');
var file = __dirname + '/test.json';

//Async read file
fs.readFile(file, 'utf8', function (err, data) {
  if (err) {
    console.log('Error: ' + err);
    return;
  }

  var data = JSON.parse(data);

  console.dir(data);
});

//Sync alternative
var file = fs.readFileSync(__dirname + '/test.json', 'utf8');
var data = JSON.parse(file);
console.dir(data);
