testing-streamlit-mybinder

A repo tryna see if you could run a streamlit app on mybinder

Inspired by this thread: https://discuss.streamlit.io/t/jupyterhub-streamlit/1238/5

It finally worked when github user op07n forked and fixed streamlit_call.py

Requirements

3 files:

requirements.txt or evironment.yml with
- nbserverproxy
- streamlit
- jupyter-server-proxy

a jupyter server extension script:

Here we called it streamlit_call.py and it's fairly simple

from subprocess import Popen

def load_jupyter_server_extension(nbapp):
    """serve the streamlit app"""
    Popen(["streamlit", "hello", "--browser.serverAddress=0.0.0.0", "--server.enableCORS=False"])

postBuild which enables nbserverproxy, moves the extension script and enables it

  # enable nbserverproxy
  jupyter serverextension enable --sys-prefix nbserverproxy
  # streamlit launches at startup
  mv .binder/streamlit_call.py ${NB_PYTHON_PREFIX}/lib/python*/site-packages/
  # enable streamlit extension
  jupyter serverextension enable --sys-prefix streamlit_call

To open by default you'd add ?urlpath=proxy/8501/ to the end of your mybinder link. For example, this repo's link is https://mybinder.org/v2/gh/chekos/testing-streamlit-mybinder/master?urlpath=proxy/8501/

WARNING: Make sure you have a trailing `/` at the end (`proxy/8501/` 👍 - `proxy/8501` 👎)
