Invisible.js - some models on both client and server

Invisible.js is a library that allows you to use the same data models on both the client and the server. On the server running on top of express.js, the client is sent via browserify .

What is:

• the ability to once describe the model (including typing and validation) and use it on the client and on the server,
• connection with MongoDb (when recording on the server - the object is written immediately to the database, when recording on the client, the RESTful API is used , automatically created on the server),
• Hooks to change data (events run back and forth through socket.io ).

Model description example (available on both client and server):

Invisible = require("invisible"); crypto = require("crypto"); _s = require("underscore.string"); function Person(firstName, lastName, email){ this.firstName = firstName; this.lastName = lastName; this.email = email; } Person.prototype.fullName = function(){ return this.firstName + ' ' + this.lastName; } Person.prototype.getAvatarUrl = function(){ cleanMail = _s.trim(this.email).toLowerCase(); hash = crypto.createHash("md5").update(cleanMail).digest("hex"); return "http://www.gravatar.com/avatar/" + hash; } module.exports = Invisible.createModel("Person", Person); 

Use on server:

 Invisible = require("invisible") john = new Invisible.Person("John", "Doe", "john.doe@mail.com"); john.fullName(); //John Doe 

Use on the client:

 <script src="invisible.js"></script> <script> jane = new Invisible.Person("Jane", "Doe", "jane.doe@mail.com"); alert(jane.fullName()); //Jane Doe </script>

P.S. This library is a great example of isomorphic javascript . More to such good!
