streamlit-jupyter-magic

A local streamlit server for Jupyter environments, and more.

Installation

pip install streamlit-jupyter-magic

Example

# Cell:
import streamlit_jupyter_magic

# Cell:

import streamlit as st

st.title("This is a Test")

if st.button("Click me!"):
    st.button("Click me again!")

Results in the following:

Limitations

1. Currently doesn't work on colab, due to a couple of colab bugs
2. To use in multiple notebooks that are open simultaneously, use the --port flag (see below)

Flags

Use any of these flags with %%streamlit FLAGS...

• --port NUMBER - set the port for streamlit to use; default is 5000
• --host HOST - set the host for streamlit to use; default is "localhost"
• --name NAME - set the name (a unique instance id) for this cell app; default uses Jupyter cell ID
• --width VALUE - set the app width, such as "100%"
• --height VALUE - set the app height, such as "700px"
• --use-colab-workaround - on colab, use a window rather than iframe, but still doesn't work (colab bug)

Under the hood

streamlit-jupyter-magic uses streamlit pages to keep memory usage down.

The magic code can be found in: streamlit_jupyter_magic/init.py

The rest of the code is utility code for managing the streamlit server.
