Ember.js is an application framework for building sophisticated browser applications. Ember.js (formerly Amber.js SproutCore 2.0) is one of the newest contenders. It is an attempt to extricate the core features from SproutCore 2.0 into a more compact modular framework suited for the web. If you want to build something that tries to tackle desktop-level application development for the web then EmberJS is for you.
The framework supports persistence, computed properties and has auto-updating (live) templates. It also should supports state management rather than the manual routing solution many other frameworks advocate. It also comes with extensive documentation ,templating and has scaffolding tools.
– Declarative bindings
– Automatic UI refresh (when the data model’s state changes, the UI updates automatically)
– Dependency tracking
– Templating (using a native template engine)
Express is a light-weight web application framework for node.js to help create a MVC web app architecture on the server side. You can then use a database like mongodb with mongoose (for modeling) to provide a backend for your node.js app. Express basically helps you manage everything, from routes, to handling requests and views. Express was specifically inspired by sinatra
Out of the box, Express provides features such as routing, templating/view rendering , dynamic CSS support, middleware (via Connect), session management, logging, application settings, and a command line interface.
