Top 23 Scala Functional programming Projects
Scala 2 compiler and standard library. For bugs, see scala/bugProject mention: Have you tried functional programming? | dev.to | 2021-09-25
Some of the most popular programming languages include Haskell, Clojure, Scala, Erlang, F#, Rust, etc.
♞ lichess.org: the forever free, adless and open source chess server ♞Project mention: How do you kill time? | reddit.com/r/AskReddit | 2021-09-24
visit lichess.org, it can kill time easily...
Scout APM: A developer's best friend. Try free for 14-days. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.
Principled Functional Programming in ScalaProject mention: In Search of the Best Functional Programming Back-End: 2021 Update | dev.to | 2021-01-24
I’ve specifically had 2 job offers internally at my company because of this language. First with Cats and Scalaz and now with ZIO, Scala has taken the best parts of Haskell, the best parts of Scala, and made it really nice to work with. You can barely see the OOP leftovers.
Generic programming for ScalaProject mention: Delphi 11 Alexandria Has Been Released | reddit.com/r/programming | 2021-09-23
please show me something like this: https://akka.io/ or this: https://zio.dev/ or this: https://github.com/milessabin/shapeless
ZIO — A type-safe, composable library for async and concurrent programming in ScalaProject mention: Pattern Matching in Java 17 and Beyond | reddit.com/r/java | 2021-09-24
ZIO (interoperates with TypeLevel to some extent)
The easy way to learn Scala.Project mention: What should I avoid coming from Java to Scala? | reddit.com/r/scala | 2021-08-19
Hahaha, I know when people ask for advice everyone throws in a book. But honestly, this one is the main "learn scala" book, and it's got a lot of examples so it's not as dry as the rest. Also there's a website where the examples can be done and validated in the browser: https://www.scala-exercises.org/
Compositional, streaming I/O library for ScalaProject mention: Introducing effects systems S.A. ZIO at work? | reddit.com/r/scala | 2021-08-23
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. :)
Run Linux Software Faster and Safer than Linux with Unikernels.
Functional JDBC layer for Scala.Project mention: Hiding Doobie's ConnectionIO implementation detail | reddit.com/r/scala | 2021-05-23
You may find this issue helpful. tl;dr you can easily make a Transactor with the void Strategy that just ignores the null Connection. But I’m with Rob: at that point, you’re not actually testing anything.
Asynchronous, Reactive Programming for Scala and Scala.js.Project mention: Alternative to RxJava/RxScala | reddit.com/r/scala | 2021-02-08
The Observer is a bit different, it returns Future[Ack] for built-in back-pressure. We can Continue / Stop synchronously or asynchronously.
Facebook's React on Scala.JSProject mention: What's the maturity level of ScalaJS? | reddit.com/r/scala | 2021-08-27
We've got server-side rendering with scalajs-react and scala-graal. Here's a tutorial if anyone's interested. What's really cool about scala-graal is that it has some pretty cool caching so that even with dynamic inputs, you can render pages in nanoseconds (as opposed to 10+ or even 100+ ms).
Optics library for ScalaProject mention: Monocle 3 release candidate - a super useful and simple library for optics with poetic api | reddit.com/r/scala | 2021-06-01
See example https://www.optics.dev/Monocle/
A simple library for creating complex neural networks
Expressive types for Spark.Project mention: Guide for Apache Spark Setup, Job Optimisation, AWS EMR Cluster Configuration, S3, YARN and HDFS Optimisation | reddit.com/r/apachespark | 2021-04-10
For type safety with dataframes, techniques like https://github.com/typelevel/frameless can be used.
Modify deeply nested case class fields
Functional GraphQL library for ScalaProject mention: Should I learn Scala for my web backend? | reddit.com/r/scala | 2021-02-23
But you can pick something else. For a modern GraphQL framework you should probably check out https://github.com/ghostdogpr/caliban
Desugaring scala `for` without implicit `withFilter`s
learn-by-doing course/tutorial for functional programming on scala
Purely functional JSON parser and library in scala.
TopShell - a purely functional, reactive scripting language
Functional programming toolbox (by TinkoffCreditSystems)Project mention: Monocle 3 Roadmap | reddit.com/r/scala | 2021-01-21
Note: I believe tofu-optics uses a profunctor encoding under the hood which let them side steps some type inference issues. Better to check with Odomontois.
Type-safe general-cryptography library - https://jmcardon.github.io/tsec/Project mention: Authentication library without Play? | reddit.com/r/scala | 2021-06-06
Tsec - https://github.com/jmcardon/tsec.
:shopping_cart: The Shopping Cart application developed in the book "Practical FP in Scala: A hands-on approach"Project mention: Good book for idiomatic Scala in 2021? | reddit.com/r/scala | 2021-09-21
If you refer to "pure functional programming" better referred to as the Programs as Values Paradigm, and if you are using / want to use the typelevel ecosystem, and you are already familiar with cats & cats-effect. Then, you probably want to check the Practical Functional Programming in Scala by Gabriel Volpe: https://leanpub.com/pfp-scala
A lightweight, distinctly Scala take on functional abstractions, with tight ZIO integrationProject mention: Scala 3 and Class Data Validation Best Practices | reddit.com/r/scala | 2021-08-31
ZIO Prelude has Validation and has recently gained support for Refined types.
