Link for compiling code with Embind → https://emscripten.org/docs/porting/connecting_cpp_and_javascript/embind.html Command for compiling code with Embind:
emcc -lembind -o test.js test.cpp -s NO_EXIT_RUNTIME=1 -s "EXPORTED_RUNTIME_METHODS=['ccall']"
- EMSCRIPTEN_BINDINGS macro is used to bind the C++ function to make it callable from JavaScript
- Emscripten compiles the C++ code to WebAssembly, generating a .wasm file and JavaScript glue code that loads the WebAssembly module and sets up the bindings
- When the HTML page is loaded, test.js is executed, loading the WebAssembly module , Emscripten's Module object is created, exposing the C++ functions (like myFunction) to JavaScript
- Example of using Module: var result = Module.myFunction(input)
