Hello everyone, I have a small query regarding on implementing a basic real time application on a simple webpage.

For context I have just enough knowledge on Python, basic API's and Flask, but I can't seem to grasp the knowledge on combining both to develop a basic real time chat application. |

Any advice on reading the documents and what should I focus on?

Thanks!

Why do you want to combine two frameworks? In general, working with two frameworks at the same time requires you to know both frameworks very well, plus the complexities of combining them. Even if you already know Flask, I think you'd be better off learning Tornado and doing the whole thing in Tornado instead of a hybrid. Or if you're set on sticking with Flask, I'm less familiar with the available options, but I think there are going to be easier ways to get real-time functionality from flask than adding on an entire separate web framework.

Honestly tornado is sufficient. You don't need flask. Tornado will help implement the http endpoints as well.

Implement websocket endpoint to connect and send receive messages.

Implement queue to push and pop messages.

You can also persist the messages if you want.

Thanks Sir Ben, I think I'll use Tornado from now on since it has more functionality for making real time web applications.

Thank you for the insight sir, I think I'll go with the Tornado route for now since upon reading the basics of documentation it supports async and websockets easily. Just need to figure out how to implement each of them. Thanks again!
