--target_dir_path: Path to the directory containing the final bundled code. If you are using webpack, this would be the equivalent of output.path option.\n
--target_node: The major node version the code will be running on. Example: 16, 18, 20...\n

--target_arch: The architecture the code will be running on. Example: x64, arm64\n
--target_stdlib: The standard library the code will be running on. Example: glibc, musl\n
--dry-run: Do not delete any files, just print the files that would be deleted.\n
