Wasm 3.0 is completed, with major new features like GC and exception handling! Scala is now acknowledged as a language that compiles to WebAssembly 🚀 webassembly.org/news/2025-0... (1/2) #Wasm #Scala

webassembly.orgWasm 3.0 Completed - WebAssemblyWebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable compilation target for programming languages, enabling deployment on the web for client and server applications.

Have you tried contributing to the compiler or metals already? #Scala Tooling spree is a great opportunity to learn how tooling works 💪

Since introducing Wasm support in Scala.js 1.17.0, there's been significant optimization of the Wasm backend! 🚀 The latest 1.20.0-SNAPSHOT, benchmarked against the 1.17.0 baseline, shows impressive progress: brainfuck +90% and kmeans +83%. Excited to see the evolution of Scala.js Wasm! #scala #wasm

Functional #JVM Meetup in Prague 🇨🇿 was a blast! It was awesome to meet fellow #functional programmers and discuss #scala over great Czech beer 🍻

Fantastic meetup yesterday! Shout out to the organizers and speakers for putting it all together. It was like looking into my CV: first job - Futures, next job - Actors, then monad transformers, and now tagless final. 😂

Model Contex Protocol coming soon to Metals for even better #Scala IDE experience. Give it a try!

As promised we are working hard on providing you with the Scala MCP server, we already have a WiP pull request ready and some courageous souls are actually testing it! You can take a look and already give some feedback at github.com/scalameta/m...

#Scala is getting an improved #AI #LLM support with MCP server in Metals. Can't wait to try it out!

Scala Space@scalaspace.bsky.social

With our new Scala MCP server we are able to eliminate hallucinations and unproductive guesswork for code that LLMs aren't familiar with by exposing API shapes from the caches of Metals and the Scala compiler.

I’ve never written or created videos about Kyo because I didn’t really grok how to use it, so this video is a helpful step in that direction! 👍 #scala

Matej Cerny@matejcerny.bsky.social

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 https://www.youtube.com/watch?v=uA2_TWP5WF4

This looks promising. I'm definitely giving it a try!

We just merged a potentially large fix to Metals that should help with cases were metals would just stop compilation. You can test it out with the latest snapshot to see if it helps with stability in your project. (1/2)

I had a quick attempt to generate #smithy sources out of #bluesky #lexicon and produce #scala SDK. Looks promising github.com/majk-p/atpro... Anyone else from #buildinpublic attempted to generalize lexicon and derive SKD out of it? What do you think about the approach?
