node-calls-python

Node.js addon that embeds Python using N-API and Python C API, allowing direct in-process execution of Python code without spawning child processes. Version 1.11.1 ships TypeScript types and supports Python 3.x. Unlike child_process or socket-based approaches, it keeps data in shared memory and avoids IPC overhead, making it suitable for rapid ML/DL model inference or small NumPy operations. Release cadence is moderate; requires node-gyp for native compilation. Better than python-shell for latency-sensitive scenarios but limited to Python 3 and may need platform-specific build setup.
