I recently came across this authentication process, I want to know, how can we avoid Logout when the user reloads the page? Code snippet: import streamlit as st import pandas as pd # Security #passlib,hashlib,bcrypt,scrypt import hashlib def make_hashes(password): return hashlib.sha256(str.enco…

Hi @Aryan_Gupta Have you tried using cache and session state: st.cache_resource ( st.cache_resource - Streamlit Docs ) for db connection st.cache_data ( https://docs.streamlit.io/library/api-reference/performance/st.cache_data ) for data, images, etc. session states ( Session State - Streamlit Docs ) f…

Yes, I tried that. Could you help me with some code snippets or a straightforward implementation? I went through that and researched a lot, but could not find how to solve that.

Is there a solution for when the user closes the window and can still stay connected for a certain time? I tried saving user data in local storage, though access to it requires using javascript (get and set to local storage using st_javascript) which refreshes the page and takes too long.

Cookies are fast but have a limit of 4kb. I am using the component streamlit_local_storage for now. While it works, it took a bit more effort than expected, I think due to reruns of the Streamlit framework but it only added about 1 sec to the load time of the page. You could maybe write sessionID t…

Thanks! Will look into it. Can you provide some snippets using your solution?

def ls_get(k, key=None): return st_js_blocking(f"return JSON.parse(localStorage.getItem('{k}'));", key) def ls_set(k, v, key=None): jdata = json.dumps(v, ensure_ascii=False) st_js_blocking(f"localStorage.setItem('{k}', JSON.stringify({jdata}));", key) ss = st.session_state if "user_i…

It seems, that I found a way to overcome the reruns for localStorage usage (and other js code). Feel free to check out this thread
