Prikrutil, I think we're on the same boat. I also come to Scala from Erlang. I like Nitrogen a lot so I decided to created a Scala web framework inspired by it.
Take a look at Xitrum. Its doc is quite extensive. From README:
Xitrum is an async and clustered Scala web framework and web server on top of Netty and Hazelcast:
- It fills the gap between Scalatra and Lift: more powerful than Scalatra and easier to use than Lift. You can easily create both RESTful APIs and postbacks. Xitrum is controller-first like Scalatra, not view-first like Lift.
- Annotation is used for URL routes, in the spirit of JAX-RS. You don't have to declare all routes in a single place.
- Typesafe, in the spirit of Scala.
- Async, in the spirit of Netty.
- Sessions can be stored in cookies or clustered Hazelcast.
- jQuery Validation is integrated for browser side and server side validation.
i18n using GNU gettext, which means unlike most other solutions, both singular and plural forms are supported.
- Conditional GET using ETag.
Hazelcast also gives:
- In-process and clustered cache, you don't need separate cache servers.
- In-process and clustered Comet, you can scale Comet to multiple web servers.
