如何一起使用 Flask 和 Telethon

Question

So i have a Flaks app, which obviously has @app.route decorators which are working after app.run() is executed. Also, i want to use in the same project telethon client event handler decorator, which is working after TelethonClient.run_until_disconected() is executed (pseudo code). How to run both process together?

The idea is to update Flask app content when Telethon receive or sends messages. In other words i want to implement Telegtam chats with real-time update in my Flask app. Thank you!

I recommend you to use Quart.

Quart is an asyncio reimplementation of the popular Flask microframework API. This means that if you understand Flask you understand Quart.

All you gotta do is start Telethon client and just run quart using hypercorn.

An example

from quart import Quart
from telethon import TelegramClient
import asyncio 
import hypercorn.asyncio

app = Quart(__name__)
client = TelegramClient(
        "Session_name",
        api_id=yourapiid,
        api_hash=youapihash
    )
async def run():
    await client.start()
    await hypercorn.asyncio.serve(app)
loop = asyncio.get_event_loop()
loop.run_until_complete(run())

To install Quart: pip install quart

Install hypercorn: pip install hypercorn

Run application: python yourscriptname

Else: use threads
