Meet a error when run release-file-system-image.yml action

[shalom-lab]

I make a repo according to the tutorial https://r-wasm.github.io/rwasm/articles/github-actions.html. The content of packages file are:

cli
dplyr
readr
ggplot2

But release-file-system-image.yml action run failed with the following error: what's wrong with it?

Hi,

The documentation on the {rwasm} package is a little out of date and needs to be rewritten. Sorry about that.

You have both deploy.yml and release-file-system-image.yml in your repository. They do slightly different things and you should only need to use one of them, depending on what you plan to do.

---

If you are intending to build an R package repository, this is already working and building an R Wasm repository from your list of packages. You can see that by running:

webr::install("cli", "https://shalom-lab.github.io/build-wasm-pkgs/")

in the webR app or in Shinylive and seeing that it is successful. The workflow file deploy.yml is handling that, and the GHA run details are here: https://github.com/shalom-lab/build-wasm-pkgs/actions/runs/8843819904

---

If you are planning on building a custom R package to be compiled for Wasm, then the file release-file-system-image.yml is designed to be added to an R package source repository and build an R package for Wasm on release. In this case, you do not have an R package yet in your repository (i.e there is no DESCRIPTION file) and so there is no R package to build and attach to your GitHub releases.

Once you create an R package in this repository, the release-file-system-image.yml workflow should begin to work.

Thanks for your quick reply. I have already understood the function of deploy.yml GHA and it works. I thought I need using the
release-file-system-image.yml but I am confused now about the function of release-file-system-image.yml GHA .

I want to put all wasm version packages in the package list into library.data' and 'library.js.metadata so I can mount this file with webr::mount(). Just like this tutorial says https://r-wasm.github.io/rwasm/articles/github-actions.html#using-an-r-package-library-image.

I am not sure whether I should use release-file-system-image.yml GHA or I need to manually build an R package library according to Building an R package library.

Please ignore the tutorial at https://r-wasm.github.io/rwasm/articles/github-actions.html#using-an-r-package-library-image. It is out of date and incorrect. I have opened an issue about it here #21.

For now, you should use deploy.yml and install your packages with e.g. webr::install("cli", "https://shalom-lab.github.io/build-wasm-pkgs/"). You can ignore release-file-system-image.yml for your use case.
