Node.js read and write file lines

Question

I tried to read a file line by line, and output it to another file, using Node.js.

My problem is the sequence of lines sometimes messed up due to async nature of Nod

Why do not you use node.js plugin for the same: https://github.com/pvorb/node-read-files

Installation: npm install read-files

Usage:

  var fs = require("fs");
      require("read-files");

  fs.readFiles([ "file1", "file2" ], "utf8", function(err, data) {
      if (err) throw err;

      console.log(data);
  });
