Binaryen.js

Binaryen.js provides prebuilt browser and Node.js binaries of Binaryen, a compiler infrastructure and toolchain library for WebAssembly. Version 129.0.0 is the latest stable release; the project follows Binaryen releases closely. It optimizes Wasm modules, performs transformations (e.g., inlining, dead code elimination), and validates/parses Wasm. Key differentiators: it works entirely in JavaScript with no native dependencies, making it suitable for web build pipelines, and it supports both ESM and CommonJS. Compared to wasm-opt CLI, it enables programmatic Wasm optimization in Node.js or browser bundlers.
