Top 23 Scala scala-j Projects

  • Mill

    Your shiny new Java/Scala build tool!

    Project mention: Mill project structure | /r/scala | 2023-12-07

    I had filed a GitHub ticket, but it was closed as "out of scope". I'm not sure why the maintainers insisted on perpetuating the ambiguity, and would like to know your opinion about the following. None of the references above answer these very basic and very important questions.

  • Laminar

    Simple, expressive, and safe UI library for Scala.js (by raquo)

    Project mention: Ask HN: Those making $500/month on side projects in 2024 – Show and tell | | 2024-01-23

    My quite niche open source project broke this threshold last year, via Github sponsorships. Of course, I put a lot of time into it, so it's not "passive income" or even "market rate income", but still, without these sponsorships I wouldn't be able to work on it so much.

    The project is Laminar, a UI library for Scala.js

  • 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.

  • jsoniter-scala

    Scala macros for compile-time generation of safe and ultra-fast JSON codecs

    Project mention: The Newest Java Json Benchmark Results just dropped | /r/java | 2023-05-01

    Afaik dsl-json came up with a lot of improvements and inspired a several other libraries like JsonIter and jsonIter-scala. Jsoniter-scala by u/plokhotnyuk is probably the most optimized JSON library on the JVM at this point, and seems to power most of the Scala ecosystem. Some implementations/optimizations eventually made their way back into Jackson and other libraries.

  • smithy4s

    Project mention: Tyrian – The Elm Architecture for Scala.js | | 2024-02-29

  • rtree2d

    RTree2D is a 2D immutable R-tree for ultra-fast nearest and intersection queries in plane and spherical coordinates

  • calico

    Calico is a UI library for the Typelevel.js ecosystem. It leverages the abstractions provided by Cats Effect and FS2 to provide a fluent DSL for building web applications that are composable, reactive, and safe. If you enjoy working with Cats Effect and FS2 then I hope that you will like Calico as well. (by armanbilge)

  • scala-json

    Compile-time JSON marshaling and abstraction for Scala, Scala Native and Scala.js

  • Demos

    Demos for ScalablyTyped (by ScalablyTyped)

  • minart

    Project mention: Indigo: A game engine for functional programmers, in Scala | | 2023-04-22

    Can't believe you didn't mention Minart! ;-) (

    The live coding experience is something where I think a lot more work could be done. This paper by Ravi Chugh et al, and a lot of his other work, points to interesting directions to take:

  • cazadescuentos
