Is manual bundling of packages possible?

[maek-ies]

dear George, dear Barret,

you are doing god's work with this package, thank you!

I know that making easy bundling possible is already in the pipeline (related issues #63, #27). My question is whether it is by any chance already possible to achieve that manually e.g. by manually copying the .data and .metadata to a certain subfolder (e.g. \shinylive\webr\vfs\usr) and then maybe just adjusting some additional lines of the existing code. Being able to freeze the deployed shinylive app in a static website without a need to download additional packages from the repo already would be fantastic. Sorry for being impatient, if this is not straightforward/possible currently, feel free to outright just close the issue, I will wait for the feature to be available.

Hi,

Indeed, we're planning on adding this soon to make it easy to bundle fixed package binaries with an app.

It is currently possible but requires a little extra work. You should be able to upload the .data and .metadata package files to static hosting in a directory relative to your app, then mount them into a new package library directory on the webR virtual filesystem using the webr::mount() function (docs).

Once the packages have been mounted, you'll need to add the virtual directory to your library path using .libPaths().

The resulting code would look something like this:

webr::mount("/custom_library/cli", "https://repo.r-wasm.org/bin/emscripten/contrib/4.3/cli_3.6.2.data")
.libPaths(c("/custom_library", .libPaths()))
library(cli)

---

Since this is not quite ready to be officially supported yet, and is largely the same as #27, we'll close this issue as a duplicate.

Thanks a lot for clarification, George!
