Hello.

At Google I/O 2011, we showcased a mobile web app. Many asked about its development timeline. Work began on March 3rd, with core coding starting on March 25th. While the calendar time was just over a month, the effort was spread across four engineers, each dedicating about 20% of their time to their respective UI using the FormFactorJS framework. This setup facilitated isolated development, with the flexibility to inject custom code per form factor and a common base controller in controller.js. We also developed and leveraged two frameworks, LeviRoutes and FormfactorJS, to efficiently consolidate common logic and specialize the controller according to form factors.

I've created LeviRoutes, a client-side JavaScript routing framework inspired by Rails. It's simple, fast, and focuses solely on handling URL changes. LeviRoutes works with HTML5 History APIs, hashchange events, and even gracefully degrades for older browsers. It supports named parameters like "/:category" for dynamic routing, allowing you to treat the URL as a controller input. Check it out on GitHub!
