GraalVM + Wasm: Fast, Efficient, Portable Apps

on YouTube ↗49m

" summary

GraalVM compiles JVM apps into Wasm with the new GraalVM Web Image preview and embeds Wasm modules in JVM apps via the GraalWasm runtime. Demo compiles a Rust image library to Wasm, integrates it into a Micronaut app compiled to native image (PGO startup ~71 ms), and sustains ~1,400 responses in 5s (~200 RPS) with 26–29 ms latency; IDE debugging steps from JavaScript into Rust Wasm frames. Current limits: no threading, networking, or native component model yet.
