I usually avoid tasks involving CI/CD pipelines, but I managed to create some cool automation (despite occasionally yelling at my screen 😀). 1. Using Tapir, I built an sbt task to generate OpenAPI specs. 2. The release job executes this task, uploading the YAML to our MkDocs-based knowledge base. 3. The Swagger UI plugin now lets everyone view service APIs without checking production's /docs endpoints. Time to buy the author of the plugin coffee 🙌

You've probably heard of Kyo, but maybe you were too lazy to read all the documentation or try it out yourself (I know I was! 😀). Watch this live demo, as Kyo will soon reach version 1.0. #scala #kyo #algebraiceffectsystem

Literal types in Scala 2 were interesting, but it's Scala 3's union types that make them truly useful. #scala

The latest release of Scalafmt introduces support for Scala.js 👏 #scala #scalajs

Kudos to @IntelliJ Scala team to already suggesting Scala 3.6 syntax ♥️ #scala #intellij

Imagine a web framework written in Gleam that uses the Elm architecture, but with components, and communicates with the backend via WebSockets. 🤩 #elm #gleam #erlang @Hayleigh Thompson

If you use Tapir, you'll almost definitely deal with some form of error handling. Recently, a default way to do this with custom case class was added to the examples folder, so check it out 👇 #scala #tapir #circe

Choosing a new language? Look for algebraic data types, pattern matching, immutability by default, and NO nulls. #nogo @Nicolas Rinaudo

"Pure functions are basically lookup tables" @Richard Feldman Did you know that the first DOOM used lookup tables to calculate goniometric functions?

After so many years using Scala, I discovered this awesomeness. On X! 😁 #scala #sbt

I doubt I'll manage to read all the books I'd hoped to this year. Thanks a lot, Warhorse Studios 😀 #KCD2

Something special from @Bartosz Milewski just arrived. Wen Rust edition @Igal Tabachnik ? 😀

Read in some discussion: "The trouble with #Haskell is, first you don't know it, and it feels awful. Then, once you learn it well, suddenly every other language feels awful." 💯

If you are into TOML, support for Scala 3 derivation was recently added to this library. I personally will stick with HOCON. By the way, does anyone use SConfig instead of the original Java implementation from TypeSafe? #scala #toml #hocon

Opaque Types are more powerful than you might think. Even named tuples are implemented with them! (👀 Notice the literal/singleton types in the commented line below) #scala

I encourage you to check this table. If your currently used plugins are already cross-published to sbt 2.x, consider updating to the next version of sbt to test its compatibility with your services.

Scala Highlights from 2024

parTraverse is definitely my most favorite combinator. #scala https://yadukrishnan.live/traversing-cats-effect-ios-part-3

Great job! 👏 And I agree that the Tuple.Map deserves more documentation and examples, as it's a powerful feature. #scala #migration
