Interact with local storage

ideally, something like this:

# write something to local storage
st.local_storage.a = 1

# reload the session, etc., 

# read it back
a = st.local_storage.a

Hi! I also use local storage to save the results of the application so that the user can continue where he left off (closed the tab or browser). The local storage was selected because cookies have limits on the size of the stored data. Now I’m doing it with the streamlit_javascript module, but if it was native with streamlit and optimize for it would be great!

@jrieke thanks for the response! one concrete use case is for my vocabulary app built using streamlit

i would like to keep track of user scores and performance, and local storage is great because i don’t need anything server side, and user data is private.

other uses i can think of:

• an app with lots of settings for some view. i can cache those settings in local storage so that when the user comes back to the app, it is in the state they left it in. st.session_storage doesn’t work because this will persist across sessions
• simple customization of apps – does the user want the app to behave a certain way? we can now remember that
• small data storage. e.g., watchlists or saved items can be stored locally
