In modern applications, Javascript is increasingly prevalent both on the client-side and to some degree on the server-side. As we continue to crank out more Javascript code, we're finding that many of the same hard-lessons we learned in writing decoupled Java code are equally desirable in Javascript code. Without the benefit of dependency injection and AOP, both Java and Javascript code can quickly become an unnavigable and untestable mess.

Where frameworks like Spring have helped us gain control over our Java code, Cujo.js similarly aims to give our Javascript code more structure and testability.

In this session, we'll look at Cujo.js, an “unframework” that provides dependency injection that takes Javascript's unique needs into consideration to create loosely-coupled code. We'll also see how, although Cujo.js isn't strictly a UI framework, elements of Cujo.js can be brought together to elegantly build client-side UIs.
