I am facing a weird problem, I am using a react frontend and flask backend, the frontend is able to connect to the event-stream data, but the eventListener is not listening to data while the server is sending it, as soon as I stop the server, the eventListener prints out all the data received till that point of time. Any idea why?

Thank you very much. What do you suggest to use if I want to take input from the user back to the server?

Hey, I have created a web app using flask and rendering a column of dataframe, as the data of that column keeps on changing, I refresh the webpage every few seconds to get latest data. I think I have to try this.

why this complex example like reading a .txt file and other things? you can also explain it simply by set a timer. you have made a simple thing more complex.
