We are actively using it at Metosin in several long-running projects and know many others who are using it too. Still, have been busy with other libs (besides real projects) so it’s not actively developed. There is #kekkonen at Slack to get help if you decide to give it a spin. Now that I remembered, need to push the 0.4.0 version out. The docs are kinda non-existing, but the lib itself is really simple so should be easy to start.
Roadmap? Yes and no. Besides fixing last issues with upcoming compojure-api 2.0.0, just polishing out reitit, a new low-level library for building fast routers and dispatchers for Clojure(Script). Most likely we’ll publish the CQRS-stuff from an ongoing project on top of that as a separate module (web-sockets & http), superseding the current Kekkonen. Or there will be “Kekkonen 2” using reitit. But anyway, there should be a path to migrate apps.
