thanks for the reply Erik, that's what I feared, I'm using vertx with the ring adapter, basically I do several http async request in my handler and I've rewrote several libs for adapt thes e to vertx, so block my server is really bad for me :D ...
http-kit offers an adaptation for ring which handle channel responses and https://github.com/mpenet/jet seems do something similar, unfortunately vertx doesnt have a big community and could take some time for get this adaptations.. seems than I'll need keep using clojure with vertx directly and don't use nice libs like compojure,buddy,liberator...that is sad...if you know about some small adapter or some code which can I use please let me know... thanks El miércoles, 25 de marzo de 2015, 17:29:29 (UTC-4:30), Erik Price escribió: > > There is no best approach for this.
