Emscripten is an LLVM-to-WebAssembly compiler toolchain that compiles C and C++ (and other LLVM-based languages) to run on the Web, Node.js, and standalone wasm runtimes. It provides Web support for portable APIs like OpenGL and SDL2, enabling complex native applications such as game engines to be ported to the browser.

Use cases

• compile c++ to webassembly
• port a native game to the browser
• run c code in node.js
• build webassembly from rust
• port an opengl sdl2 app to the web
• generate html page from c source

When to choose

• you need to run existing C/C++ codebases in the browser
• you want WebAssembly output with JavaScript glue and HTML generation
• you rely on portable APIs like OpenGL or SDL2 in a web target

When to avoid

• you are writing a new web project from scratch in JavaScript or TypeScript
• you target native platforms only
• you need minimal wasm output without a JS runtime layer
