Running Streamlit with a Telegram Bot together causes threading issues. Try this revised approach:
import streamlit as st
from telegram.ext import Updater, MessageHandler, Filters
def reply_handler(update, ctx):
update.effective_chat.send_message('Hello there!')
def setup_ui():
st.set_page_config(page_title='DemoApp', layout='wide')
def start_bot():
updater = Updater('YOUR_BOT_TOKEN')
updater.dispatcher.add_handler(MessageHandler(Filters.text, reply_handler))
updater.start_polling()
updater.idle()
if __name__ == '__main__':
setup_ui()
start_bot()
i used threading so each ran in its own thread, but had to carefully manage shared states. works fine for small projects, but might need more robust solutions for heavy loads.
In my experience, attempting to handle both the Telegram Bot and the Streamlit app within the same thread can lead to unforeseen issues and race conditions. Instead of using threads, I decided to run the two processes separately using Python’s multiprocessing module. This approach allows each component to operate independently and eliminates the complexity associated with thread management. It required setting up inter-process communication to synchronize state when necessary. Although there was some initial configuration overhead, this method resulted in a more robust and maintainable deployment.
Integrating the two components asynchronously proved beneficial in a recent project I worked on. I restructured both the bot and the Streamlit app to operate within an asyncio event loop, leveraging async libraries to handle I/O-bound tasks. This method not only improved responsiveness but also reduced complications associated with thread management. Although refactoring took some time, working with asyncio made maintaining and scaling the application much more straightforward. It was a worthwhile shift from a multi-threaded approach and improved overall reliability.
i fixed it by launching both apps using subprocess.Popen from a main script. it kept them isolated and dodged the threading headaches. works decently on my end.
