Emscripten is a complete open-source compiler toolchain that transforms C, C++, and other LLVM-based source code into WebAssembly (and JavaScript), enabling native‑like applications to run in web browsers, Node.js, and other Wasm environments. While Emscripten mostly focuses on compiling C and C++ using Clang, it can be integrated with other LLVM-using compilers (for example, Rust has Emscripten integration, with the wasm32-unknown-emscripten and asmjs-unknown-emscripten targets). Emscripten provides Web support for popular portable APIs such as OpenGL and SDL2, allowing complex graphical native applications to be ported, such as the Unity game engine and Google Earth. It can probably port your codebase, too.
Features
- Converts C/C++ code to WebAssembly or JavaScript for broad platform reach
- Supports standard portable APIs like OpenGL and SDL2 for graphical apps
- Emulates POSIX environment including libc functionality in browser
- Ability to produce standalone Wasm binaries without JS runtime
- Tools like emcc act as drop-in replacements for gcc/clang for ease of use
- Enables porting complex native applications (e.g., games, Google Earth) to web environments efficiently
