You can use fs.readdir and path.extname

var fs = require('fs')
  , path = require('path');

function getFileWithExtensionName(dir, ext) {
  fs.readdir(dir, function(files){
    for (var i = 0; i < files.length; i++) {
      if (path.extname(files[i]) === '.' + ext)
        return files[i]
    }
  });
}

var homedir = "/usr/home/jordan";
var mytxtfilepath= getFileWithExtensionName(homedir, 'txt')
fs.readfile(mytxtfilepath, function(err,data) {
  console.log(data);
});
