@platformatic/python-node v2.0.0 supports HTTP streaming and WebSockets for real-time Node.js and Python ASGI app integration

Platformatic

@platformatic/python-node v2.0.0 introduces HTTP streaming and WebSocket support, enabling real-time bidirectional communication between Python ASGI applications and Node.js. The release implements ASGI 3.0 protocol with new handleStream() method for incremental response processing, request body streaming with backpressure, and full WebSocket support. This enables use cases like server-sent events, live dashboards, chat applications, and ML model inference while maintaining backward compatibility. The streaming architecture provides proper backpressure between languages, reduces memory footprint for large responses, and allows immediate access to headers before body completion.
