Workflow engine in Javascript [closed]

问题:

Does anybody know a workflow engine (such as Spring WebFlow) for Javascript? We have a home-made framework that allows us to guide site navigation using JSON, but its quality is far from good.

Edit based on given answers: the engine must run on the browser and reduce to minimum the number of requests to the server.

dataflo.ws

It's a JSON-based workflow engine. It features:

• modular design
• several useful built-in tasks (MongoDB, OAuth, RabbitMQ)
• HTTP initiator with a router

Works on Node.js, in browsers (including IE9) and in PhoneGap.
