Question

Running Flask webserver and TCP server at the same time

Posted October 8, 2019 1.1k views

I would like to run a webserver and a socket server at the same time, is this possible?
The webserver will make a JSON file available at a specified URL and the TCP server will listen on an arbitrary port for a connection to receive data and process it. The socket server will run as a thread.

Hello, @elektray

You should be able to setup this using Nginx to open the specific port.

You can follow this article and see how to setup Flask with uWSGI and Nginx as a reverse proxy:

This one is for Flask with Gunicorn;

Let me know if you have any questions.
