It would be interesting
Do you mean “write a new web app that behaves like Jupyter”?
If what you want is Jupyter, try JupyterLite which is already doing the Pyodide/WASM/serverless thing.
You may also find the pyscript REPL (see the examples) interesting: this shows the promise of an extremely stripped-down jupyter-like experience, and I expect many apps to be built on this element.
thanks for your answer, I should search google before ask this question lol.
Thanks for the reply, hope it to archive that in the future
