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 streamlitcall.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 loadjupyterserver_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/streamlitcall.py ${NBPYTHON_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/ :thumbsup: - proxy/8501 :thumbsdown:) | | --- |
