Meet Chicory, exploit the power of WebAssembly on the server side!
summary
A pure Java Wasm interpreter called Chicory runs Wasm modules with zero external dependencies, loads user-uploaded .wasm files into a Spring Boot app, creates instances, calls exported functions and returns typed results; examples include TinyGo-compiled functions returning 8 for 5+3, running a Wasm CLI inside the JVM, compiling Opa policies to policy.wasm for per-request authorization, and even running Doom; integration respects thread interrupts and offers an experimental Naot path while inspired by wazero design.
