Graal: Using JVM libraries in Node.js

on YouTube ↗46m

" summary

GraalVM + Truffle lets Node run JVM libraries by starting Node with --jvm and exposing a global Java object; synchronous Java calls work directly but block the event loop. A bcrypt Java lib integrates, warms to about 8,000 requests per second (roughly 50% slower than native), but concurrent logins collapse throughput. A thread-safe callback wrapper called bindCallback plus a worker queue is built to let JVM threads safely invoke JS and await a Promise; it works but adds complexity and operational risk.
