jupyterlite VS BrowserFS

The JupyterLite Python-compiled-to-WASM build has NumPy, SciPy, matplotlib, and SymPy installed; so you can do computer algebra with SymPy in a browser tab.

Agreed that would be a killer feature. Unzip this package and get a functional Python + Jupyter + scientific (numpy, pandas, scipy, matplotlib) environment.

I have been on-and-off teaching some people Python and the initial setup on-ramp is horrible. Ok, so install Python, now ignore-this-for-now-complications: create a "virtualenv", use this thing called "pip", install these half-dozen things to get a basic notebook (Jupyter + scipy things), install these other half-dozen quality of life things, you should probably also have "conda" for the future, etc. That's a lot of nonsense for someone I am trying to show an alternative to Excel.

My shortcut, "You want to try Python?" approach has been to start with JupyterLite[0] where I can immediately get people coding and delay that pain.

JupyterLite: a JupyterLab distribution that runs in the browser\ (45 comments)

I think JupyterLite is using localStorage by default. But there are File System APIs for WASM and some external projects[0], I don't think they're yet integrated.

I started my file system with BrowserFS which allowed me to setup IndexedDb as the main writeable location. When in Firefox Private mode it switches to an in memory file system which does not persist. Using BrowserFS also meant I could open ZIP and ISO files as if they were folders. I create a JSON file on build that has the initial public folder directory structure which is used as the readable portion of the file system via plain HTTP GET requests. I've also added the ability to extract RAR files, although I don't currently have it linked to File Explorer to see it's contents before extracting. I can also make and extract ZIP/ISO via fflate.

Thanks for the interest! To do git I used https://isomorphic-git.org/, the terminal is backed by https://xtermjs.org/ and the file system that it writes to is coming from https://github.com/jvilk/BrowserFS. This is all part of my side project (https://github.com/DustinBrett/daedalOS) to build a web desktop environment.

Thanks, I'm glad to hear you liked it! I am using BrowserFS to create writeable data on IndexedDb.
