Hi,

you may find this library interesting:

I don’t know if this could be what you are looking for.

page: feed.py

import streamlit as st

def show_feed_page(user_id):
    st.subheader("Test")
    st.write(f"User ID: {user_id}")

page: home.py

import streamlit as st

def show_home_page():
    st.title("Home Page")
    st.write("This is the home page content.")

app.py

import streamlit as st

from pages.home import show_home_page
from pages.feed import show_feed_page

# Mock database
class MockDatabase:
    users = {"1234": {"name": "David Oden", "email": "doden@xxxxx.com"}}

    @staticmethod
    def check_user_exists(user_id):
        return user_id in MockDatabase.users

if "page" not in st.session_state:
    st.session_state.page = "home"
if "userid" not in st.session_state:
    st.session_state.userid = ""

def login_action(id):
 
    user_exists = MockDatabase.check_user_exists(id)

    if user_exists:
        st.success(f"Login successful! Welcome, {MockDatabase.users[id]['name']}!")
        st.session_state.page = "feed"  # Go to the next page
        st.session_state.userid = id
    else:
        st.error("User not found. Please check your ID.")


with st.form(key="login_form"):
    id_input = st.text_input("User ID", type="password", placeholder="4 digit pin (1234)")
    login_button = st.form_submit_button("Login")

# Check if the form is submitted
if login_button:
    login_action(id_input)

# Render content based on the current page
if st.session_state.page == "home":
    if st.button("Go to Feed Page"):
        st.session_state.page = "feed"

    show_home_page()

elif st.session_state.page == "feed":
    if st.button("Go back to Home Page"):
        st.session_state.page = "home"

    show_feed_page(st.session_state.userid)
