    # TODO(ryanking13): These files need to be generated dynamically during the build process
    # by running a executable.
    # However, since we build a side module, the emitted executable is a wasm object
    # so it is not runnable even with the emulator (node).
    # I think there should be a proper way to emit a js file which is runnable with node,
    # But I was to exhausted to find it. So I created these files locally.
