In next generation web apps like Twitter and Google Docs, all data is realtime and collaborative. These companies had to invest a great deal of time and talent to achieve this.

Derby represents a new breed of frameworks that brings such capabilities into a single developer’s reach. It is a full-stack JavaScript MVC framework that provides shared server and client rendering, automatic data synchronization, and realtime conflict resolution. Derby makes it simple to write applications that load as fast as a search engine, are as interactive as a document editor, and work offline.

Derby delivers on the promise of server / client code reuse. It renders pages in both places with the same routes, templates, and business logic—reducing loadtime and providing graceful degradation.

Derby automatically syncs data everywhere in realtime. Like many client MVC frameworks, template bindings automatically update the view when the model changes and vice-versa. Beyond this, Derby includes a powerful data synchronization engine called Racer, which automatically syncs data among browsers, servers, and a database.

Racer supports offline usage and sophisticated conflict resolution out of the box. Advanced applications like Google Docs and Git have solved these with algorithms including operation transform and diff-match-patch. Racer makes such techniques accessible to all web developers.
