🐻‍❄️ streamlit-rerun-bear

Turns every Streamlit rerun into a polar bear dash across your screen.

A lightweight Streamlit custom component (CCv2) that animates a polar bear running along the bottom of the page on every rerun — left to right, then right to left, alternating each time.

Installation

pip install streamlit-rerun-bear

Quick Start

import streamlit as st
from streamlit_rerun_bear import streamlit_rerun_bear

streamlit_rerun_bear()

st.button("🔄 Rerun")

That's it. Every time the app reruns, a polar bear dashes across the bottom of the screen.

How It Works

• Rendered on a position: fixed canvas that stays pinned to the bottom of the viewport — even while scrolling.
• pointer-events: none ensures the bear never blocks clicks or interactions.
• Direction alternates on each rerun (left → right → left → …).
• If a rerun happens mid-animation, the bear picks up from where it left off.

Requirements

• Python ≥ 3.9
• Streamlit ≥ 1.40.0
• Pillow ≥ 9.0.0
• NumPy ≥ 1.24.0
