ci(r): attach webR wasm assets to r/v* GitHub releases - #318
Merged

Conversation
shinylive's only path for installing a GitHub-hosted R package is a release
tagged with the installed RemoteRef carrying library.data* and
library.js.metadata assets. shinyreact has no such release, so a
{shinylive-r} block using it aborts at render time.
Adds release-r-wasm.yaml, which calls r-wasm/actions'
release-file-system-image reusable workflow on every published r/v* release,
pinned to the webR version shinylive ships (v0.6.0 / R 4.6.0).

Closes #268.
shinylive:::get_github_wasm_assets()is the only path shinylive has for aGitHub-installed R package: it looks up
/repos/posit-dev/shinyreact/releases/tags/<RemoteRef>and wantslibrary.data*+library.js.metadataassets on it. This repo has no Rrelease, so any
{shinylive-r}block using shinyreact aborts at render.release-r-wasm.yamlcalls r-wasm/actions'release-file-system-imagereusable workflow on every published
r/v*release. It builds a webRfilesystem image of
pkg-r/plus dependencies and uploads the two assets.Two repo-specific details:
pkg-r/, sopackages: local::./pkg-r.pak::pak("posit-dev/shinyreact/pkg-r@r/v0.1.0")recordsRemoteRef: r/v0.1.0. Verified that pak parses a slashed ref and thatgh::gh()resolvesreleases/tags/py/v0.1.0against this repo, so theexisting
r/vprefix convention holds.webr-imageis pinned toghcr.io/r-wasm/webr:v0.6.0— the webR shinyliveships (R 4.6.0). An image built against another R version won't load.
releaseevents only run workflows from the default branch, so this has tomerge before the
r/v0.1.0tag and release are created. That unblocksschloerke/presentation-2026-09-15-posit-conf-shinyreact#7.
If this turns out to need more work, the tag and release can be deleted and
re-cut.
