WebAssembly and Node.js

on YouTube ↗27m

" summary

Node 8 runs WebAssembly and the demo compiles a C compression library to wasm with emscripten then loads it in Node, exposing a decoder via a small JS shim. The build produces a wasm module that interoperates with Node buffers, uses malloc/free into linear memory, and the wrapper is about 19 lines of wrapper code. Performance sits below native bindings but beats pure JS decoders; the module is sandboxed and portable, drops into any wasm‑capable VM, and the prototype works.
