Node.js User Signup Socket - A pattern I'm testing out to for a socket that handles user signup actions using MongooseJS and Passport.

NodeJS-SIGNUPSocket.js

var hat = require('hat');

module.exports = function (socket, handleError, config) {

  // set some common items we will need from config
  var route = config.route;
  var userModel = config.model;

  socket.on(route, function (data) {

    var rack = hat.rack();
    var token = rack();

    var newUserConfig = {
      username: data.email,
      token: token
    };
    var password = data.password;

    userModel.register(new userModel(newUserConfig), password, function (err, newProfile) {

      if (err) {
        return handleError(route, err);
      } else {
        var successData = {
          token: newProfile.token
        };
        socket.emit(route + ':success', successData);
      }

    });

  });

};
