The best way is to try and build a web app and learn along the way. Here's the stack I use for all my Haskell web apps: - Stack to manage the project and dependencies. - WAI and Warp to construct your own bare bones web app (see https://broch.io/posts/build-your-own-wai-framework/ https://broch.io/posts/build-your-own-wai-framework/). I don't like frameworks like Yesod or Spock because I like to keep it simple. - blaze-html (https://hackage.haskell.org/package/blaze-html https://hackage.haskell.org/package/blaze-html) for constructing HTML. - selda (https://selda.link https://selda.link) for PostgreSQL/SQLite interface (it might be too much for beginners, but there's other modules like postgres-simple). - wai-extra for form/file upload parsing, gzip, and other basic middleware. - wai-middleware-static for serving static files - aeson for JSON encoding/decoding This stack is what I use for building webapps with Haskell. If you're building JSON REST APIs you might want to look into Servant. I haven't used it personally but I hear good things. I strongly recommend learning the basics of Functors, Applicatives, and Monads before venturing into building applications: See http://adit.io/posts/2013-04-17-functors,_applicatives,_and_monads_in_pictures.html http://adit.io/posts/2013-04-17-functors,_applicatives,_and_... and http://adit.io/posts/2013-06-10-three-useful-monads.html http://adit.io/posts/2013-06-10-three-useful-monads.html If you know how Functors, Applicatives, and Monads work then you can understand almost everything about Haskell. Good luck! Feel free to email me if you have questions.
