Top 17 Scala Fp Projects

  • Shapeless

    Generic programming for Scala

    Project mention: Scala 3: modifying product types in compile-time | reddit.com/r/scala | 2022-07-14

    If that's what you want, you can use Shapeless' records and HList. You can probably replicate this in plain Scala 3 with tuples and literal types as you said. It won't play nice with your others libs though but maybe there are integrations.

  • FS2

    Compositional, streaming I/O library for Scala

    Project mention: Grasping the concepts and getting them down to earth | reddit.com/r/scala | 2022-11-04

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

  • Monix

    Asynchronous, Reactive Programming for Scala and Scala.js.

    Project mention: Scala isn't fun anymore | reddit.com/r/programming | 2022-09-10

    The author is the creator of Monix and implemented the first version of cats-effect. He knows what he is doing.

  • cats-effect

    The pure asynchronous runtime for Scala

    Project mention: Should I Move From PHP to Node/Express? | reddit.com/r/node | 2022-10-13

    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.

  • scalajs-react

    Facebook's React on Scala.JS

    Project mention: Monorepo: seeking for an advice for bi-lang project | reddit.com/r/scala | 2022-07-31

    Then there's scalajs-react, which can be integrated with existing React ecosystem, but it's just sooo compex: macros, 5-6 type parameters, hundreds and hundreds of cryptic types. We decided to stick with TypeScript instead.

  • frameless

    Expressive types for Spark.

    Project mention: Why use Spark at all? | reddit.com/r/dataengineering | 2022-10-19

    To add to this I lately have used Spark with frameless for compile time safety and it's an interesting library that works well with Spark.

  • InfluxDB

    Build time-series-based applications quickly and at scale.. InfluxDB is the Time Series Data Platform where developers build real-time applications for analytics, IoT and cloud-native services in less time with less code.

  • trading

  • distage-example

    Example project built using distage, tagless final, http4s, doobie and zio

    Project mention: Testimonials about the usage of Izumi BIO typeclasses | reddit.com/r/scala | 2022-03-14

    I have been looking at the distage example (https://github.com/7mind/distage-example), and it looks very promising for writing effectful programs that work both with ZIO and cats-effect as the effect implementation. Although I do wonder if the same can be achieved by defining the APIs in terms of a trifunctor effect, instead of the bifunctor effect type showcased in the example.

  • pencil
