So it’s a bit “out there” but the JupyterLab notebook is currently able to be completely “hosted” on a static web page using Pyodide kernels using web assembly. This is Python running directly within the user’s browser. No application server needed: [image] GitHub - jupyterlite/jupyterlite…

I created a separate thread focusing on stlite . [image] New library: stlite, a port of Streamlit to Wasm, powered by Pyodide 💬 Show the Community! Hello everyone balloon, I have started a new project, stlite ( GitHub - whitphx/stlite: A port of Streamlit to Wasm, powered …

This idea also crossed my mind :slight_smile: and actually I recall multiple Creators have toyed with the idea: @whitphx @asehmi if you want to pop in the conversation with your experiences. It will probably run through the same issues as Install with pyodide · Issue #7764 · dask/dask · GitHub : t…

@andfanilo I haven’t done anything in this space as yet :slight_smile:

Hi, thanks for mentioning me :slight_smile: Although I have not made any progress on code yet, I will dump my thoughts here roughly: Execution flow overview of Streamlit at initialization (code reading memo) Launch the server process The server serves these paths: /.*: Static files including i…

[image] whitphx: For such rewrite, I think the Streamlit repository have to be forked Surely not forked, instead just have the required preparatory refactoring rework undergone within the main repository first achieving the required decoupling. I think its quite important to keep this ecosyst…

@SimonBiggs That’s right. I didn’t want to refer to the project fork. I wanted to say just about technical issue that some fixes are needed on the core and the development must be tightly coupled with the core development, which is different from Jupyter Lite. The fork here simply means “forking …

I have nothing technical to add to the conversation, just to also say I would very much appreciate this feature and I think it could be transformative to Streamlit as a whole :slight_smile:

Hi, I have started working on this. I will share the progress when I make something sharable :slight_smile:

I made my first progress: Stlite playground (On this page, ~50MB resources will be loaded including the Pyodide runtime and some Python packages) On this sample page you can see that Streamlit is running on the browser. There is no server-side Python; it’s an SPA hosted on GitHub Pages. And you ca…

Technically, I did “fork” the streamlit main repo: Comparing streamlit:develop...whitphx:stlite · streamlit/streamlit · GitHub because the original Streamlit cannot run on Pyodide as it uses some features that Pyodide/WASM runtime do not support, such as threading. I had to replace them with Pyodid…

Feature idea, Pyodide JupyterLite like Streamlit
