How to set the default page in multipage app? (I don’t want to use main/welcome page)

I have my pages in pages/ folder, they get picked up correctly by the sidebar.

I have no need for the welcome page, I’d like the first page to be automatically loaded when main.py is ran

Steps to reproduce

Code snippet:

My main.py file has effectively nothing in there:

import logging
import streamlit as st



# Initialize logging
logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)

My folder structure is:

- Root
  - main.py
  - pages
    - 1_page_one.py
    - 2_page_two.py
    - 3_page_three.py

Expected (or rather, desired) behavior:

I’d like the pages/1_page_one.py to be opened when main.py is ran. I also don’t want to see main.py in page selector.

Actual behavior:

When I run the 1_page_one.py directly, I see no sidebar. When I run main.py, I get the sidebar and an empty page (space for welcome page).

Good question, @Lucas_Severyn!

I suggest trying the st-pages module. I haven’t tried it for your specific use case, but I believe it should do what you are after.

Let us know how it goes… and welcome to our forums, by the way! :wink:

Best,

You could also do this

- Root
  - 1_page_one.py
  - pages
    - 2_page_two.py
    - 3_page_three.py

And then do streamlit run 1_page_one.py

Not the cleanest solution, but it works. Thanks for the suggestion!
