Spring 7 goes polyglot with python, javascript & wasm
🔸 TLDR
Spring Framework 7.1 is exploring GraalVM polyglot support so we can run JavaScript, Python and WebAssembly (Wasm) inside Spring apps via Graal languages. This is roadmap / enhancement work (issue #35725), not GA yet — but it opens the door to true polyglot Spring applications. 🚀
🔸 WHAT’S HAPPENING?
▪️ Spring is looking at GraalJS as the natural successor to the removed JDK Nashorn engine 🔁
▪️ GraalPy would let us plug into the massive Python ecosystem from our Spring apps 🐍
▪️ GraalWasm could enable integrating Wasm workloads alongside Java 💿
▪️ There’s already a precedent via Spring Integration’s PolyglotScriptExecutor
▪️ Impact on org.springframework.scripting and ScriptTemplateView is being evaluated 🧩
🔸 WHY THIS MATTERS FOR SPRING DEV 🚀
▪️ Mix Java + Python + JS + Wasm in one Spring app where it makes sense
▪️ Reuse existing Python/JS business logic instead of rewriting everything in Java
▪️ Prepare for multi-language microservices living under a single Spring umbrella
▪️ Keep Spring relevant in a world where polyglot runtimes and AI tooling are the norm
🔸 TAKEAWAYS
▪️ This is an enhancement on the Spring 7.1.x roadmap, not a feature you can use in prod today ⚠️
▪️ It’s about options, not about “replacing Java” in Spring 😉
▪️ If you love Java and Python/JS, the future Spring stack may feel like home 🏡
