DerbyJS
MVC framework for realtime, collaborative web applications that run in Node.js and in browsers.
DerbyJS is built on a data synchronization engine, Racer, and renders the same templates in the browser and on the server. A project can hold one or more single-page apps, each with models, templates and routes, and the server side plugs into Express as router middleware. The documentation covers the framework, and the getting-started page lists Node.js and MongoDB as what a first app needs.
Worth knowing
The getting-started page calls the MongoDB adapter the most complete of the database adapters, and Redis is optional for scaling pub/sub beyond one server process. The install page gives an npm command only for the derby-examples repository, not for the framework package itself.
