snap VS up-to-date-real-world-haskell

I also looked into Snap (http://snapframework.com/) and Yesod (https://www.yesodweb.com/) for Haskell. I didn't really get anywhere with those though because I had build issues with dependencies and was in a bit of a hurry so I put them off for later.

As with most languages, there are several good web frameworks. See for instance snap

Snap (http://snapframework.com/) and Scotty (https://hackage.haskell.org/package/scotty) are both projects that can fit this description.

There is an effort to update it to modern Haskell. It has gotten quite far and it is still on going.

It is a very good book that is unfortunately outdated, some of the code doesn't run anymore because of changes to GHC and the Haskell library ecosystem that have happened over the last 15 or so years. There was an online effort to update the book but it hasn't been finished and I don't think anyone is currently working on it, but the git repo is here if you want to look at it.

This is a bit old, but you can see some examples of how using Parsec might look: https://github.com/tssm/up-to-date-real-world-haskell/blob/master/14-using-parsec.org

If you're looking to get back into Haskell, The Haskell Planetarium will be a good source of new articles: https://haskell.pl-a.net/As for Real World Haskell, I believe there is a an update that should be more modern: https://github.com/tssm/up-to-date-real-world-haskell, but I only read the original many years ago.Another good source of information is to just search Github, and see what libraries the most popular Haskell projects are using.

A lot of people suggest Project Euler or “just do a project”, but personally I found it helpful to have a bit more guidance. Practical Haskell is a great beginner guide, focusing on how to actually do stuff rather than all the theory behind it. The 2008 version is good but a little out of date, there’s an updated version in progress that’s complete enough that you should be able to get started.
