ReasonConf 2019 Logo

The ReasonML conference for web developers & OCaml enthusiasts

WU Campus, Vienna, Austria

On the Road to Production

Last year, we have been eagerly onboarding newcomers to the language and we will continue to do so. This year, the conference is all about shipping products and tools built with Reason & OCaml.

  1. Workshops & Knowledge Transfer

    The first day is dedicated to different workshops for different skill levels and topics. There are beginner friendly workshops about Reason and ReasonReact as well as more advanced workshops about GraphQL and OCaml. Our workshop leaders are more experienced Reason / OCaml users and Reason core team members. Check the ticket section for details.
