What changed

  • .github/workflows/publish.yml rewritten for npm Trusted Publishing (OIDC) — same design as cellarnode-auth's publish.yml, with pnpm mechanics substituted for the install/test/build steps:
    • permissions: { contents: read, id-token: write } scoped to the publish job, not the workflow — a job added to this file later won't inherit id-token: write it doesn't need.
    • actions/checkout@v4 with fetch-depth: 2 + persist-credentials: false.
    • actions/setup-node@v4 (node 22, registry-url) + pnpm/action-setup@v4 (version 10). No cache: pnpm on setup-node — release builds don't cache.
    • Upgrades npm to ^11.5.1 — pinned, not @latest: npm 12 is already out and warns that setup-node's always-auth config stops working in the next major (Node 22 bundles npm 10).
    • New gate step compares package.json's version at HEAD against the push event's previous main SHA (github.event.before), falling back to HEAD~1 only if that SHA can't be fetched — before survives the rebase merges this repo allows, where HEAD~1 can land on the wrong commit.
    • When changed: pnpm install --frozen-lockfile (no separate --ignore-scripts needed — pnpm 10 already refuses dependency lifecycle scripts unless allow-listed; verified locally, esbuild's build script was ignored by default), pnpm test, pnpm build, the existing unauthenticated npm view guard, then npm publish --access public — no NODE_AUTH_TOKEN / secrets.NPM_TOKEN anywhere. No @cellarnode dependencies, so no token appears anywhere in the job. Provenance is generated automatically (public repo + public package).
  • README.md: added a "Publishing" section (no Makefile in this repo, so it documents the version-bump-and-push flow rather than make release-*).

npmjs.com Trusted Publisher configuration required

The first publish after this merges will fail with ENEEDAUTH until a Trusted Publisher row exists on npmjs.com for @cellarnode/i18n:

Field Value
Organization CellarNode
Repository i18n
Workflow filename publish.yml
Environment (blank)

Allowed actions must include direct npm publish. npmjs.com's Trusted Publisher setup always allows staged publish (npm publish --provenance via the tarball-attestation flow); direct npm publish from CI additionally requires the Allowed actions setting to be turned on explicitly, or the first release fails with ENEEDAUTH. npm also does not validate this configuration when it's saved — a typo'd Organization/Repository/Workflow filename looks fine at save time and only surfaces as a failure on the next push to main.

Verification

  • actionlint on .github/workflows/publish.yml: zero findings.
  • CI=true pnpm install --frozen-lockfile && pnpm test && pnpm build: pass.

Summary by cubic

Switches @cellarnode/i18n publishing from a long-lived NPM_TOKEN to npm Trusted Publishing (OIDC), so a version bump merged to main publishes automatically with no token in the job.

The publish workflow now skips install, test, build, and publish when package.json's version is unchanged since the previous main commit. Provenance stays automatic (public repo + public package). The README documents the version-bump-and-push publishing flow.

Migration

  • Add a Trusted Publisher row on npmjs.com for @cellarnode/i18n (Organization CellarNode, Repository i18n, Workflow publish.yml, no Environment) before the next publish; without it, the first publish after this merges fails with ENEEDAUTH.

Written for commit d0036d8. Summary will update on new commits.

Review in cubic

Same shape as auth's publish.yml with pnpm mechanics instead of npm: pnpm
10 install/test/build, no package-manager cache in the release build, no
@CellarNode dependencies so no token anywhere in the job. Gated on
package.json's version having changed vs HEAD~1; provenance stays
automatic (public repo + public package).

📝 Summary

Summary by CodeRabbit

  • Documentation
    • Added publishing guidance to the README, including automatic npm publishing through trusted authentication when package versions change on the main branch.
    • Documented that long-lived npm tokens and manual publishing are not required.
  • Chores
    • Updated the release workflow to validate, build, test, and publish packages using automated trusted publishing.
    • Publishing now occurs only for new package versions.

Walkthrough

The publish workflow now uses GitHub OIDC for npm Trusted Publishing. It gates validation and publication on package version changes. The README documents the automated release process.

Changes

npm publishing

Layer / File(s) Summary
Version-change workflow gates
.github/workflows/publish.yml
The workflow configures OIDC permissions, shallow checkout, pnpm, and npm. Dependency installation, tests, build, and npm version checks run only when the package version changes.
OIDC publishing and release documentation
.github/workflows/publish.yml, README.md
Publishing uses npm Trusted Publishing and requires a changed version that does not exist on npm. The README documents the automated release flow and provenance generation.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to d0036

The tokenless publishing flow is otherwise validated, but the npm CLI should be pinned before merge to prevent an unexpected upstream release from affecting package publication.

Suggested labels: enhancement

Poem

A rabbit checks the version gate,
Then hops through OIDC’s path.
No token rests in secret soil,
npm sees the trusted publish toil.
The README marks the way.

  • In .github/workflows/publish.yml, the global npm upgrade runs on every push to main even when changed=false and publishing is skipped, adding unnecessary workflow work; move the upgrade into the publishing path where the required npm version is needed.

Linked issue: CEL-1733: npm trusted publishing (OIDC) for @cellarnode/beverage-utils, finance, ui

Status Acceptance criteria Notes
Use npm Trusted Publishing via GitHub Actions with id-token permission and no long-lived NPM_TOKEN/NODE_AUTH_TOKEN for publishing. The workflow grants id-token: write and removes token-based publish configuration; npm publish has no authentication token environment variable.
Publish automatically after a version bump on main, while skipping unchanged versions. The workflow compares the current package version with HEAD~1 and gates install, verification, and publish on a changed version.
Run the package install, test, and build steps before publishing. All three pnpm steps are present and run before the npm version check and publish step when the version changed.
Retain the unauthenticated npm view guard for the public package. The existing guard remains and is gated to run only for version changes before publishing.
Publish @cellarnode/i18n publicly with automatic provenance and document the new publishing flow. The workflow publishes with public access and the README documents OIDC publishing and version-bump-triggered releases; the repository and package are public as specified by the issue.

Pin npm to ^11.5.1 instead of @latest, scope permissions to the publish
job, gate the version check against github.event.before (rebase-merge
safe) with HEAD~1 fallback, and document why pnpm needs no separate
--ignore-scripts flag.
