emscripten-wasm-toolkit

Compiles C and C++ into WebAssembly with Emscripten: picking emcc flags, exporting functions so JavaScript can call them through ccall and cwrap, sizing and growing the WASM heap, using Asyncify to pause synchronous C during async JavaScript, shrinking or speeding up binaries with optimization levels and wasm-opt, producing debuggable builds, and choosing browser versus WASI targets. Use when the user mentions emcc, EMSCRIPTEN_KEEPALIVE, EXPORTED_FUNCTIONS, the Emscripten memory model, Asyncify, optimizing or debugging a .wasm file, or WASI versus browser builds. Not for Rust or AssemblyScript targets, hand-written WAT, server-side WASM runtimes, or ordinary native C compilation.
