But you do have other options than emitting binary wasm yourself. You can use a compiled version of wabt or binaryen, here's an example of binaryen.js, https://github.com/WebAssembly/binaryen/blob/master/test/binaryen.js/test.js https://github.com/WebAssembly/binaryen/blob/master/test/bin... edit: actually it looks like the test doesn't cover WasmBinaryWriter, which is what would be needed for this, we should improve that
