Streamlit App API calls

[stergioa]

Hello, I would like to see All internal API POST &GET calls that streamlit is performing, I think that this kind of documentation is not provided but would be much appreciated.

I have currently detected through network packets monitoring, calls to :

./static/js/
.static/css/
.static/media/
./_stcore/host_config
./_stcore/stream
./_stcore/health

Is there a detailed API documentation?

At least on the forward side, I believe Streamlit's python backend communicates with the frontend using a Websocket interface (that's the /stream endpoint you're seeing) which carries protobuffer-encoded messages. So there isn't a REST API per-se.

streamlit runs on a tornado HTTP/WS server. I think the routes init code is here
