Nodepp-WASM

The DOOM of Async Frameworks: Write Once, Build Everywhere, Process Everything.

Nodepp is a groundbreaking C++ framework that bridges the gap between the language's raw performance and the developer-friendly abstractions of Node.js. By providing a high-level, asynchronous API, Nodepp empowers you to write C++ with a familiar syntax—enabling seamless development across cloud servers, desktop apps, and microcontrollers.

At its core, Nodepp features a 100% asynchronous architecture powered by an internal Event Loop. This allows for massive concurrency and scalable task management with minimal code complexity, effectively bringing the "Write Once, Run Everywhere" philosophy to the world of high-performance C++.

💡 Featured Project: Duck Hunt VR (WASM Edition)

To showcase Nodepp for Web, we ported the classic Duck Hunt to Virtual Reality, running natively in the browser via WebAssembly. This project pushes the limits of web-based VR by combining low-level C++ performance with modern Web APIs.

💡 Featured Project: Cursed-Luna (WASM Remake)

Cursed-Luna is a high-performance remake of the Global Game Jam 2018 classic. Originally built around the theme of Transmission, this version has been completely rewritten in C++ using Nodepp and Raylib to bring tight gameplay mechanics to the browser via WebAssembly.
