The Derby MVC framework makes it easy to write realtime, collaborative applications that run in both Node.js and browsers.
Derby includes a powerful data synchronization engine called Racer that automatically syncs data between browsers, servers, and a database. Models subscribe to changes on specific objects, enabling granular control of data propagation without defining channels. Racer supports offline usage and conflict resolution out of the box, which greatly simplifies writing multi-user applications.
Derby applications load immediately and can be indexed by search engines, because the same templates render on both server and client. In addition, templates define bindings, which instantly update the view when the model changes and vice versa. 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 and Racer are alpha software. While Derby should work well enough for prototyping and weekend projects, it is still undergoing major development. APIs are subject to change.
A simple chat demo. Note that as you edit your name, it updates in realtime. Name changes also show up in the page title and other rooms. Check out the source in the examples directory to see how these bindings are created automatically.
