Project description
streamlit-server-state
A "server-wide" state shared across the sessions.
import streamlit as st
from streamlit_server_state import server_state, server_state_lock
st.title("Global Counter Example")
with server_state_lock["count"]: # Lock the "count" state for thread-safety
if "count" not in server_state:
server_state.count = 0
increment = st.button("Increment")
if increment:
with server_state_lock.count:
server_state.count += 1
decrement = st.button("Decrement")
if decrement:
with server_state_lock.count:
server_state.count -= 1
st.write("Count = ", server_state.count)
As above, the API is similar to the built-in SessionState, except one major difference - a "lock" object. The lock object is introduced for thread-safety because the server-state is accessed from multiple sessions, i.e. threads.
Examples
app_global_count
: A sample app like the official counter example for SessionState which usesstreamlit-server-state
instead and the counter is shared among all the sessions on the server. This is a nice small example to see the usage and behavior ofstreamlit-server-state
. Try to open the app in multiple browser tabs and see the counter is shared among them.app_global_slider
: A slider widget (st.slider
) whose value is shared among all sessions.app_chat.py
: A simple chat app usingstreamlit-server-state
.app_chat_rooms.py
: A simple chat app with room separation.
