Tips and Tricks for GraalVM and Graal Languages in IntelliJ IDEA

on YouTube ↗01h 00m

" summary

Shows how GraalVM builds and debugs real apps: use native image heap dumps to compare snapshots (native image heap file is larger but RSS drops from ~500MB to ~170MB), enable a JDWP preview that embeds a tiny Java interpreter plus a metadata file and .so/.dylib to attach the IntelliJ Java debugger, use the GraalPy Gradle plugin to create a packaged venv and call Python via context.eval(...).as(Interface.class), and run WebAssembly/Rust (photon) for image filters with Chrome/IDE inspector stepping from JS into Rust.
