Deeplinks for specific tab/pages

ssap · July 21, 2022, 1:57am

I have been looking for a way to send a user to a given tab/page of the app by providing them a custom url, just like a deeplink.

I saw this discussion but as far as I understand it would only keep in memory text
or checkbox status. Deep Links In Streamlit?

I also tried using anchor link but without sucess.

Any lead or help would be very much appreciated!

Here is what I use

github.com

rcsmit/streamlit_scripts/blob/main/menu_streamlit.py

import streamlit as st
import importlib
import traceback
import os
import platform


st.set_page_config(page_title="Streamlit scripts of René Smit")


def dynamic_import(module):
    """Import a module stored in a variable

    Args:
        module (string): The module to import

    Returns:
        the module you want
    """
    return importlib.import_module(module)

This file has been truncated. show original

Most essential lines are

   query_params = st.experimental_get_query_params() # reading  the choice from the URL..

    choice = int(query_params["choice"][0]) if "choice" in query_params else 0 # .. and make it the default value

Kind regards
Rene Smit

Hi @rcsmit @ssap, I use a similar module loading technique as @rcsmit. Logic works fine to load/select different code modules. But there are 2 issues. (1) Page reloads each time, so flickers a lot. (2) Each page is a new instance, so session variables don’t work. I’m look into new MultiPage (don’t like the sidebar page list), or Tabs (for fast reload). If you have better luck, please share.
