It's painful in Haskell you're learning it but feel you're not able to generate anything real for the first month(s) with it. Unfortunately, there's not many up-to-date tutorials like these available for beginners.
I learned Haskell at uni and am interested in going back to it for web work (instead of Erlang). Any insights you might be able to share would be really helpful!
As for the SQL story, that's more fragmented. I'm still trying to figure out the best next step myself. I started off with Persistent & Esqueleto but now looking at BEAM, Selda and Squeal for more control over the queries.
If you use Persistent as the persistence layer, check out Matt Parsons' blog for a nice intro: https://www.parsonsmatt.org/2016/07/08/servant-persistent_up...
I'm actually coming from Elixir myself. I have to admit Haskell feels funny at times but admittedly a lot more robust.
