You can also specify that you only want to load and use a limited subset of the types provided:

var mongoose = require("mongoose");

var mongooseTypes = require("mongoose-types");
// Only load the email type
mongooseTypes.loadTypes(mongoose, "email");

Using the types

Once you are setup, you can begin to use the new types.

Email

var Email = mongoose.SchemaTypes.Email;
var UserSchema = new Schema({
  email: {
      work: Email
    , home: Email
  }
});

Url

var Url = mongoose.SchemaTypes.Url;
var VisitSchema = new Schema({
    url: Url
  , referer: Url
});

var db = mongoose.createConnection("mongodb://localhost/sampledb");
var mongooseTypes = require("mongoose-types")
  , useTimestamps = mongooseTypes.useTimestamps;
var UserSchema = new Schema({
    username: String
});
UserSchema.plugin(useTimestamps);
mongoose.model('User', UserSchema);
var User = db.model('User', UserSchema);

var user = new User({username: 'Prince'});
user.save(function (err) {
  console.log(user.createdAt); // Should be approximately now
  console.log(user.createdAt === user.updatedAt); // true

  // Wait 1 second and then update the user
  setTimeout( function () {
    user.username = 'Symbol';
    user.save( function (err) {
