JWebAssembly

JWebAssembly is a compiler that translates Java bytecode into WebAssembly, enabling Java applications to run in web browsers or other Wasm-compatible environments. Instead of requiring JavaScript as an intermediary, it directly converts compiled Java classes into WebAssembly modules, preserving performance and reducing overhead. The project supports a subset of the Java standard library and focuses on enabling practical execution of Java programs in web contexts. It provides tools for handling memory management, method calls, and data structures within the constraints of the WebAssembly runtime. Developers can use JWebAssembly to port existing Java applications to the web or build new applications that leverage Java’s ecosystem while targeting Wasm. The compiler also supports integration with build tools and workflows, making it accessible for typical Java development pipelines.
