Streamlit Cookie Banner Component

A custom Streamlit component to display a basic cookie banner on your Streamlit web application. This component allows you to display a cookie consent message with customizable text and an optional link to a privacy policy or other relevant information.

Installation

You can install this component by adding it to your project and running the following command after packaging it:

pip install streamlit-cookie-banner

Usage

To use the cookie banner in your Streamlit app, you simply import the cookie_banner function from the component and use it within your Streamlit app like this:

import streamlit as st
from streamlit_cookie_banner import cookie_banner

consent = cookie_banner(
    banner_text="We use cookies to ensure you get the best experience.",
    display=True,  # Set to False if you want to hide the banner
    link_text="Learn more",  # Optional: Link text (e.g., 'Learn more')
    link_url="https://your-privacy-policy-url.com",  # Optional: URL to your privacy policy
    key="cookie_banner"  # Optional: A unique key to control re-rendering
)

Use the consent

import streamlit as st
from streamlit_cookie_banner import cookie_banner

consent = cookie_banner(
    banner_text="This website uses cookies to improve your experience.",
    display=True,
    link_text="Read our Privacy Policy",
    link_url="https://example.com/privacy-policy",
    key="cookie_banner"
)

if consent:
    st.write("Thank you for accepting cookies!")
else:
    st.write("Please consider accepting cookies to improve your experience.")

Consent is returned as None if user hasn't selected Agree/Disagree, True for Agree & False for Disagree. After selection the value is stored in local session cookies to avoid showing the cookie bar again.

Frontend Assets

The component uses frontend files located in the frontend/public directory. These files are responsible for rendering the banner in the browser. You can edit these to control the styling etc of the banner.
