cask VS pfps-shopping-cart

I want to just block as if there's no tomorrow, no effects / hardcore FP (maybe only something like https://github.com/softwaremill/ox), what would you use? E.g. for http server / db / json ?https://github.com/com-lihaoyi/cask ?

There's the Li Haoyi's ecosystem of tools and libraries that's fun to hack on, has a low entry-bar (with a design philosophy of using the least complex abstractions for the job), and has few libs like requests and cask that may appeal to those liking some python minimalism. That's not the fastest way to learn hardcore FP, that's not the worst either.

Wonder if anyone uses: https://github.com/com-lihaoyi/cask

Is play-framework a strong requirement? If not, you might have an easier time building a simple API and serializing JSON with the lihaoyi ecosystem, namely cask as the microframework and uPickle/uJson.

For people who want to get their feet wet with Scala, I highly recommend Cask and the rest of what some people affectionately call “the Singapore stack,” in honor of Li Haoyi, its developer. He emphasizes tasteful use of Scala features with an emphasis on API ergonomics. All of his work is a joy to use.

The documentation points to a pretty outdated example. Can you try with the latest 0.8.3 release?

If you want something really easy and simple, have a look at cask: https://com-lihaoyi.github.io/cask/

Best I can do is Cask: https://com-lihaoyi.github.io/cask/ 😅

Gabriel Volpe has a book that goes over just that using the typelevel stack. I highly recommend it: https://leanpub.com/pfp-scala

The only issue I had was how to put all this knowledge together. For that I bought Practical FP in scala by Gabriel Vlope, it's not for beginners, tho but takes you through a project with the latest typelevel stack. Here's the link. https://leanpub.com/pfp-scala.

This is a really good book https://leanpub.com/pfp-scala

If you want a solid understanding of FP and not just FP in Scala, I highly recommend installing GHCup and working through Haskell Programming From First Principles. Then I would work through Scala With Cats, Essential Effects, and Practical FP in Scala for how all of that maps onto Scala.

Practical FP in Scala

BTW for learning good application structure with Tagless Final I really recommend the book Practical FP in Scala and its work-along example application. That's where I stole the pattern above from.
