What problem does it solve?

This Skill simplifies the process of compiling C/C++ code into WebAssembly (WASM) using the Emscripten toolchain, enabling web-based execution of native code.

Core Features & Use Cases

  • C/C++ to WASM Compilation: Use emcc to generate .wasm files from C/C++ source.
  • Function Exporting: Expose C functions to JavaScript using EXPORTED_FUNCTIONS and EXPORTED_RUNTIME_METHODS.
  • Memory Management: Configure WASM memory and stack sizes, and interact with C memory from JS.
  • Asyncify: Adapt synchronous C code for asynchronous JavaScript environments.
  • Debugging & Optimization: Build with debug info and optimize WASM binaries using wasm-opt.
  • WASI vs Browser Targets: Differentiate and build for server-side (WASI) or browser environments.
  • Use Case: Integrate a high-performance image processing library written in C++ into a web application by compiling it to WebAssembly with Emscripten.

Quick Start

Install Emscripten SDK and compile a C file named 'hello.c' to 'hello.js' and 'hello.wasm' using the 'emcc' command.
