pre-download all dependencies

[hoishing]

I am trying to create mobile apps with stlite, and tried to bundle all stlite dependencies into the mobile app bundle. However its not that straight forward as I thought... stlite.js is a wrapper, many wasm whl file from pyodide is dynamically downloaded during startup. How can I create a completely local stlite setup that don't require network access during the first run?

The exact feature to do it is not developed yet and it's in the ticket now: #901
Plz be patient for it.

Technically it's possible, and actually the @stlite/desktop does such pre-fetching before bundling the files into an Electron app. (so the ticket above would be something like it).

An Stlite user created a script that turns Stlite apps into standalone HTML files as #1523 so it may help.

what https://github.com/LukeAFullard/script2stlite does is automating the stlite setup process, so all wasm and python wheels still need to be downloaded during startup... I think the closest thing for what I want is packages/desktop/bin-src/dump_artifacts in @stlite/desktop, that pre-fetch all wasm and wheels then put it in the app bundle to save some initial loading time.

However, in #1022, its quite surprising that "The most time-taking part is loading the packages into the memory", which make me re-consider if its worth to put effort on pre-fetching the wasm and wheel files... 🤔
