FS2 VS scala-pet-store

Recently, CE3 has had similar issues reported across multiple repositories, almost an epidemic of reports!

Thanks for the explanation!

So it's pull based and not push based like most other streams lib.

Does maybe someone know how this compares to FS2 or Iteratees than? (Both are also pull based streaming solutions).

https://en.wikipedia.org/wiki/Iteratee

Looks quite similar to me. Is the Scala FS2 lib maybe even a clones of the Haskell solution? Or are they different in important aspects?

Most important/known: * https://http4s.org/ - an HTTP client/server * https://github.com/typelevel/fs2 - streaming * https://github.com/tpolecat/doobie - JDBC

On the contrary, switching to the functional mindset, with something like Typelevel Scala3 and respective cats and cats-effect fs2 frameworks, helps to rethink a lot of designs and development approaches.

fs2 for streaming.

Finally, the last chapter has been rewritten to be based on some of the main design ideas from FS2 (https://fs2.io), which I hope will be more approachable than the 1st edition.

Just to clarify, is your doubt about the meaning of the api, or do you think you have found a bug? In either case, you can also open a Github discussion https://github.com/typelevel/fs2/discussions.

Another more reactive solution would to use signals, as in FPR sinal network. fs2 implements this very nicely here https://github.com/typelevel/fs2/blob/8b285a6b54c63d43ed6aa3bb91365652035c90e5/core/shared/src/main/scala/fs2/concurrent/Signal.scala

Assuming the bug mentioned here is https://github.com/typelevel/fs2/issues/2568, we came up with a partial fix in a day (https://github.com/typelevel/fs2/pull/2569) and a complete fix in 2 days: https://github.com/typelevel/fs2/pull/2572. Note the original bug was opened on a Saturday. :)

In addition to the great work from Gabriel Volpe, there's the Scala Pet Store and a to-do app.

Hello, you can try to look for pet store implementations on GitHub using Scala, like https://github.com/pauljamescleary/scala-pet-store. The "Pet Store" is usually an example repo demonstrating how to build a CRUD service. Since Scala is a language capable of expressing multiple design techniques, multiple ways of solving similar problems exist, which is neither good nor bad, just irritating for a beginner.

Hi guys, finish you know of any good github sample apps, written in scala, in proper functional style ? the ⠀goal is to see actual production code that is FP worthy, to look up to :) I am looking to see how FP looks in practice similar to https://github.com/pauljamescleary/scala-pet-store or https://github.com/hcwilhelm/twm I have 2 years of scala experience, mostly akka tech stack, and some basic cats knowledge. Thanks Mircea
