want to configure my Streamlit application so that it starts with a specific page

Using Streamlit

I would recommend using built-in streamlit multipage support instead of custom functions like you’re using. There are currently two supported methods:

  1. Just use pages/ folder: Create a multipage app - Streamlit Docs
  2. Use st.page_link: Build a custom navigation menu with `st.page_link` - Streamlit Docs

For example, here’s a method using st.page_link:

nav_example.py

import streamlit as st


def add_navigation():
    st.set_page_config(page_title="Nexo_admin", page_icon=":robot:", layout="wide")
    st.sidebar.header("Navigation")
    st.sidebar.page_link("main_page.py", label="Home", icon="🏠")
    st.sidebar.page_link("pages/admin.py", label="Admin", icon="🔑")
    st.sidebar.page_link("pages/chatbot.py", label="Chatbot", icon="👾")

main_page.py

import streamlit as st
from nav_example import add_navigation

add_navigation()

st.title("Main Page")

pages/admin.py

import streamlit as st
from nav_example import add_navigation

add_navigation()

st.title("Admin")

And so on.

If you then do streamlit run main_page.py, it will run the main page, and have links in the sidebar to go to the other pages, like this
