Streamlit + Notion test app

Write Streamlit apps using Notion!

☠️ IMPORTANT: This is just a little prototype I made to play with some ideas. Not meant for production!

• Example app: https://share.streamlit.io/tvst/notionlit/main

• Notion page with source code: https://www.notion.so/streamlit/NotionLit-d500932b258b43298b509eb6dd3db230

  👉 Try editing the Notion page, then going to the app and pressing R to refresh!

Forking instructions

1. Fork this app into your own repo (or just copy streamlit_app.py. It's fully self-contained!)

2. Create a new integration in Notion. When you're done, grab the secret token as you'll need it later.

3. Create a page in Notion, then:

   1. Share it with your integration
   2. Grab the page URL as you'llneed it later.

4. Deploy your app with share.streamlit.io.

5. Set up your app's secrets, adding in the secret token and page URL from the steps above.

   [notion]
   token = "YOUR_NOTION_SECRET"
   page_url = "YOUR_NOTION_PAGE_URL"
   

🥳 Done!

Now any time you edit your Notion page, go into your Streamlit app and press R to rerun it (thereby fetching the latest content from Notion).

But wait, there's more!

If you add a code block in Notion and mark it as a Python block, it will actually get executed when you load your app!

So try adding a Python block with this into your Notion page:

import streamlit as st
import numpy as np

num_rows = st.slider("Number of rows", 1, 500, 100)
data = np.random.randn(num_rows, 5)

st.write(data)
st.line_chart(data)

(If you need other Python packages, add them to your requirements.txt)

One more thing: let's say you want to execute Python code, but don't want to pollute your Notion page with too much ugly code. There's a hack for that. Just put the code inside an expander without a title or with a title equal to "Code".

What's supported

• Headers
• Paragraphs (with bold/italic/strikethrough/links)
• Images
• Code blocks
• Expanders
• @user_mentions
• @date_mentions

And that's all ☹️

Again, this is just a proof-of-concept / prototype. So I didn't implement a bunch of other stuff, like underline, @page_mentions, columns, etc.

Also note that not everything in Streamlit is supported either. I don't have an exhaustive list but, for example, magic doesn't work.
