This is _really_ cool. I don't know why a lot of commenters here are going into the weeds to grouse about Java, flash, and general anger at computational notebooks.<p>What we have here is a complete client-side browser environment for development. Not some half-assed language or hyper restricted toy--this is real Python, and your browser's full JS engine all available in JupyterLab's IDE (basically a simpler VS Code at this point, it uses the same editing component).<p>We all freaked out a bit as Apple drove out IDEs from their app store, Google locked down Termux and similar developer tools from Android. Well, here's the answer to those situations. Something no app store owner can kill on a whim. I love stuff like this and hope it helps to enable and inspire the next generation of developers.
Despite Pyolite has a miserable performance (20MB of downloads), the overall project direction is correct.<p>I said this already 10 years ago: We don't need more cloud computing but need to empower users end devices again. Jupyter is typically operated on powerful notebooks and not on mobile devices.
I use frequently the basthon notebook <a href="https://notebook.basthon.fr/" rel="nofollow">https://notebook.basthon.fr/</a> which is also a wasm powered jupyter (based on pyodide) and quite like it. It's flying a bit under the radar as it's not translated in other langage than french. How does it compare to this project?
Just to throw in my 2c. I'm a big fan of jupyter notebooks for data visualisation and prototyping pipelines. Being able to run all of your data analysis code then run your visualisation code without having to repipe your data is great.<p>For other projects such as bots, webapps or regular programming I'll use vscode or neovim.<p>Which brings me to a neat feature in vscode that has me starting to do my data vis there. The `# %%` in python files lets me run code blocks in the same way as a notebook, but then i can run the file top to bottom aswell. It is starting to change the way i prototype.
Not to mention it can open and edit .ipynb files
How far are we away from having _collaborative_ Jupyter in the browser? Would love a Google Docs experience of sharing a no-sign up required link to help remotely teach basic python.
