How to make site update every 10 seconds?

Question

Python

I made this nonsense:

@app.route("/chat")
def _chat():
    with open("db/lastauthor.txt", "r") as file:
        author = file.read()
    with open("db/lastmsg.txt", "r") as file:
        content = file.read()
    return render_template("chat.html", author=author, content = content)

And I need this "nonsense" to be updated every 10 seconds, this is necessary so that I do not have to reload the page to check the last message

Answer 1

this is usually implemented in JavaScript (Flask will return a fresh page at any time, and the browser should force something to automatically reload the page)

Answer 2

Use sockets.
They allow you to create a streaming connection between the client and the server, which in turn.

• will allow the server to tell the front in real time that it needs to update the data on the page.
  
• will reduce resource consumption (supporting a single connection instead of processing dozens of requests)
