  • cats

    Lightweight, modular, and extensible library for functional programming.

    Project mention: Beware of teammates who refactor code based on personal taste without proper documentation or completeness. Sounds familiar. | /r/programming | 2023-07-05

    A functional programming library: https://typelevel.org/cats/

  • Scalaz

    Principled Functional Programming in Scala

    Project mention: Going into year 2 of Software Development Foundation Degree, have a particular liking for OOP and SQL, any tips, info or pointers on where to go from there? | /r/cscareerquestions | 2023-05-29

    I'm sorry, but have you ever done functional programming for a real company, like in a functional programming language like Haskell, Scala, or F#? Have you ever used Scala cats or scalaz? Have you ever learned category theory and how to apply its abstractions in software? Listen u/judethedude2106 this person hasn't gone as far down the functional programming rabbit hole as I have. Beyond learning the basics like the difference between pure and impure functions, what are closures, what higher order functions are and the most common ones like .map, .filter, and .flatmap, the immutable collections like immutable linked lists and trees, and what a Monad is and common monads like those used for futures/promises, async programming, and Option (Some or None, which is used instead of null checking), the more advanced functional programming stuff like category theory based abstractions are totally useless for real jobs and is just a giant time suck. Don't waste years on functional programming, spend at most a few months on it and no more.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • Shapeless

    Generic programming for Scala

    Project mention: Question regarding Recursive datatypes and cats typeclasses (Haskell to Scala) | /r/scala | 2023-07-06

    Scala 2-only: * Shapeless (there is Shapeless for Scala 3 but less often needed as basic things are in Scala 3)

  • Twitter Util

    Wonderful reusable code from Twitter

  • Ammonite-Ops

    Scala Scripting

    Project mention: RFC: A Path Forward for Ammonite REPL and Scripts in 2023 and Beyond | /r/scala | 2023-09-03
  • refined

    Refinement types for Scala

    Project mention: Make Invalid States Unrepresentable | dev.to | 2024-02-02

    Scala has quite good support for refined types across multiple libraries. A solution using the refined library might look something like

  • Monocle

    Optics library for Scala

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • better-files

    Simple, safe and intuitive Scala I/O

  • Enumeratum

    A type-safe, reflection-free, powerful enumeration implementation for Scala with exhaustive pattern match warnings and helpful integrations.

    Project mention: How to implement `if-else if -else if -else` with cat effect IO in Scala? | /r/scala | 2023-05-16

    I'm not sure I understand what Cats or cats-effect has to do with what you're trying to do. As far as I can tell, it sounds like what you're asking is simply "what's the best way to implement an enumerated type in Scala?" The best answer to that I'm aware of is Enumeratum.

  • Scala Async

    An asynchronous programming facility for Scala

  • Chimney

    Scala library for boilerplate-free, type-safe data transformations

    Project mention: Chimney 0.8.0 (stable) released | /r/scala | 2023-10-13
  • scala.meta

    Library to read, analyze, transform and generate Scala programs

  • Cassovary

    Cassovary is a simple big graph processing library for the JVM

  • Simulacrum

    First class syntax support for type classes in Scala

  • Scala-Logging

    Convenient and performant logging library for Scala wrapping SLF4J.

  • n-scala

    A new Scala wrapper for Joda Time based on scala-time

  • Quicklens

    Modify deeply nested case class fields

  • Freestyle

    A cohesive & pragmatic framework of FP centric Scala libraries

  • Eff

    Eff monad for cats - https://atnos-org.github.io/eff

  • Scala Graph

    Graph for Scala is intended to provide basic graph functionality seamlessly fitting into the Scala Collection Library. Like the well known members of scala.collection, Graph for Scala is an in-memory graph library aiming at editing and traversing graphs, finding cycles etc. in a user-friendly way.

  • scribe

    The fastest logging library in the world. Built from scratch in Scala and programmatically configurable. (by outr)

    Project mention: Engenharia de Dados com Scala: aprenda a fazer webscraping dos filmes mais assistidos da Netflix em cada país | dev.to | 2023-11-27
