How to read the content of files synchronously in Node.js?

You need to use readFileSync, your method is still reading the files asynchronously, which can result in printing the contents out of order depending on when the callback happens for each read.

var fs = require('fs'),
    files = fs.readdirSync(__dirname + '/files/');

files.forEach(function(file) {
  var contents = fs.readFileSync(__dirname + '/files/' + file, 'utf8');
  console.log(contents);
})
