Excited to talk about @graalvm.org and #WebAssembly tomorrow at @devoxx.com! 🚀
Join me to explore Web Image and GraalWasm — and see them in action with plenty of live demos.
Fabio @fniephaus.com will introduce Web Image, a new preview feature of GraalVM that enables compiling applications into efficient Wasm modules, including use cases and live demos.
We'll also look at GraalWasm, a new embeddable Wasm runtime.
