Looks like #WasmEdge is the first standalone #Wasm VM that supports and enables #WebAssembly 3.0 out of the box.
Big milestone. Shout-out to the team! ๐

Glad to see #WasmEdge progress with supporting #Wasm 3.0 features.
Almost all features are supported and enabled(!) by default!

danilo's book, server-side webassembly, is now available in print!

During the last year and a half, I wrote a book on server-side WebAssembly. Getting into Wasm is hard. Resources are scattered, the tech is complex, and it's constantly changing. I wanted to contribute a resource to make learning easier. manning.com/books/server... (1/5) ๐งต

AFAIR the main question for now is getting 2 impls in browser engines.

We are using standalone version of jsc for that.
Though, unfortunately, it doesnโt allow to catch/reproduce problems existing only on (mobile) devices.

The Kotlin/Wasm based Compose for Web browser debugging capability that @sebi.io demoed below is very nice (kotlinlang.org/docs/whatsne...). Showing example here in ClimateTrace KMP/CMP sample (github.com/joreilly/Cli...).

Still looking for a job. I'm leaning to things like intersection of native and JavaScript, runtimes, developer tooling, browsers, WebAssembly, web security.
