Breeze.js

Breeze can help developers create JS-based RIAs that manage data both on the client and server side.

Created on top of MVC and MVVM development patterns, Breeze.js allows programmers to separate their business logic from their front-end UI, making it easier to use JavaScript in a professional and efficient way for creating complicated desktop and Web-based apps that usually would imply the usage of a more advanced language, like Java, Ruby or Python.

To do this, the library comes with a programmatic API that provides a wide set of features and a lean learning curve.

Breeze is available as a NuGet package as well.
