I have created a Python package contains easy-to-use functions to copy text to the clipboard
within Streamlit applications, supporting both HTTP and HTTPS contexts.
Key Features
-
Works seamlessly on both HTTP and HTTPS:
Supports the modern, secure Clipboard API (navigator.clipboard.writeText
) used in HTTPS environments,
and falls back to the legacydocument.execCommand('copy')
method for HTTP or older browsers. -
No dependency on UI elements:
Clipboard copy commands can be triggered programmatically anywhere in your Streamlit app
without requiring explicit user interaction with buttons, making integration flexible and convenient.
Why Use This Package?
Streamlit apps run inside iframes and are often served over HTTPS, which imposes strict browser security policies on clipboard access.
This package provides a reliable way to copy text to the clipboard regardless of the protocol or browser limitations.
Installation
pip install st-clipboard
Usage Example
Here is an example Streamlit app showing two columns with text inputs and buttons — one using the secure clipboard copy (for HTTPS), and the other using the unsecured fallback (for HTTP):
import streamlit as st
from st_clipboard import copy_to_clipboard, copy_to_clipboard_unsecured
# Create two columns: HTTPS (left), HTTP (right)
col_https, col_http = st.columns(2)
with col_https:
st.markdown("### HTTPS Clipboard Copy")
https_text = st.text_input("Enter text to copy (HTTPS):", value="Hello HTTPS")
if st.button("Copy to clipboard (HTTPS)"):
copy_to_clipboard(https_text)
st.success("Copied to clipboard using secure method!")
with col_http:
st.markdown("### HTTP Clipboard Copy")
http_text = st.text_input("Enter text to copy (HTTP):", value="Hello HTTP")
if st.button("Copy to clipboard (HTTP)"):
copy_to_clipboard_unsecured(http_text)
st.success("Copied to clipboard using unsecured method!")
