Embind and Emscripten: Blending C++11, JavaScript, and the Web Browser
summary
Explains concrete tooling and results: Emscripten compiles C++ to asm.js (~half native speed) and Embind exposes C++ libraries to JavaScript with a tiny implementation (three headers), using C++11 constexpr and variadic templates to emit compact runtime binding code. Covers bi‑directional calls, value types to avoid manual deletes, and wire‑type framing; reports 175 kilobytes saved from light type ids and about 200 nanoseconds overhead per cross‑language call. Shows working IMVU ports, WebGL and WebAudio examples.
