What

A new Release workflow (.github/workflows/release.yml) stages @ably/pubsub-core, @ably/pubsub-device and @ably/pubsub-server on npm with npm stage publish. It authenticates through OIDC trusted publishing in the npm environment, so no npm token is stored. A staged version goes live only after a maintainer approves it with 2FA. Approve core first, because device and server pin its exact version.

Triggers: a published GitHub release, which stages that release's tag, or a manual run with a tag and an optional dist-tag.

Dist-tag: latest for a stable version, otherwise the pre-release identifier, so 3.1.0-beta.2 gets beta. A numeric identifier, as in 3.1.0-0, gets next. A pre-release is never tagged latest.

How

• Two jobs. build runs npm ci and the full build with only contents: read. stage is the only job with id-token: write and the npm environment. It downloads the build output and runs scripts/release.js, which uses only Node built-ins, so no dependency install script or build plugin can obtain the token.
• scripts/release.js gains --stage and --tag, so CI keeps the existing preflight: version sites agree, build artifacts exist, every package packs cleanly in a dry run, and packages go out in dependency order. npm is now invoked with an argv array instead of a shell string. --tag and --otp values are validated.
• CONTRIBUTING.md: the release steps now create the GitHub release (which triggers staging), approve the staged versions, then run Publish to CDN. A local OTP publish stays as a fallback.
• Repository URLs: device and server's repository.url now names ably/ably-pubsub-js, matching core. Trusted publishing rejects a package whose repository.url doesn't match the repo the workflow runs in, so without this they would fail after core had already staged.

Known limitations

• Re-runs while versions are staged fail. npm refuses to stage a version that is already staged, and the OIDC token can't run npm stage list to detect it. Reject the staged versions, or approve them if the earlier run succeeded.

Summary by CodeRabbit

• New Features
  • A published GitHub release can now trigger package staging on npm for approval. Release tooling also supports custom npm dist-tags and one-time passwords.
• Documentation
  • Updated release instructions to cover creating a GitHub release, approving staged packages in dependency order, and handling staging failures.
• Bug Fixes
  • Release commands now validate option values and provide clearer guidance when staging fails or completes.

Walkthrough

The pull request adds a GitHub Actions workflow that builds and stages npm packages from a release or manual dispatch. It adds staging options to the release script, updates release instructions, and changes repository URLs in the device and server package manifests.

Changes

Release staging

Layer / File(s)	Summary
Select release and build artifacts .github/workflows/release.yml	The workflow accepts release and manual triggers, selects and validates the version and dist-tag, and uploads built package artifacts.
Add staging and publish options scripts/release.js	The release command validates tag and OTP values, runs npm from each package directory, and reports staging results and recovery steps.
Stage packages and document approvals .github/workflows/release.yml, CONTRIBUTING.md	The workflow downloads the build artifact and stages packages in an OIDC-enabled job. The release instructions describe staging and the required approval order.

Package repository metadata

Layer / File(s)	Summary
Update package repository URLs packages/device/package.json, packages/server/package.json	The repository URLs in both package manifests now point to ably/ably-pubsub-js.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: Moderate · previous review 65b9a

The new release flow is largely sound, but the documented pre-release process can overwrite stable CDN bundles. The first-run trusted-publisher setup and the direct-publish fallback after staging are also not documented. Resolve or explicitly accept these before merging.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Validate VERSION before it is used in ref and run steps.

VERSION comes from inputs.version or the release tag. A manual run can supply any text. The value is interpolated into ref: refs/tags/${{ env.VERSION }}. The run: scripts read it from the environment, so shell injection is not possible there.

The workflow does not validate the value against a semver pattern before checkout. A malformed value fails late or selects an unintended ref. The dist-tag step does check its own value, but only after checkout and install.

Add a first step that validates VERSION and fails before checkout. Alternatively, use a ref input that cannot contain path separators.

Also consider restricting workflow_dispatch to maintainers. The npm environment approval already gates the stage job. The build job still runs unapproved code from the chosen tag with no secrets.

Also applies to: 50-50, 120-120

Reject pending stages before direct publishing.

If staging succeeded but the maintainer chooses the local fallback, the staged versions still reserve those package versions. Direct publishing will fail until the maintainer rejects the pending stages. Document that step for the fallback as well. (docs.npmjs.com)

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Rename command to avoid shadowing the top-level command.

Line 260 declares const command inside publish(). The switch (command) at Line 296 uses a different, top-level command. This is not a bug, because the block scope is separate. The shadowing is easy to misread, and a later edit that moves code could break it. Rename the local variable, for example to npmSubcommand.

♻️ Proposed rename

-  const command = stage ? ['stage', 'publish'] : ['publish'];
-  const commandArgs = [...command, ...tagArgs, ...(otp ? ['--otp', otp] : [])];
+  const npmSubcommand = stage ? ['stage', 'publish'] : ['publish'];
+  const commandArgs = [...npmSubcommand, ...tagArgs, ...(otp ? ['--otp', otp] : [])];

Validate the build artifact paths before extraction in the OIDC job.

The build job runs npm ci, so dependency install scripts can modify build.tgz before upload. The stage job holds id-token: write. It extracts build.tgz over the checkout without checking the archive paths. A crafted archive can overwrite scripts/release.js or a tracked package.json lifecycle script. That code then runs in the job with the OIDC token. This defeats the isolation described in the header comment (Lines 13-15).

Reject any archive entry outside the three package directories. Also reject absolute paths and .. segments. The 2FA approval step limits the impact, but it does not remove the risk.

Do not deploy pre-releases to stable CDN aliases.
