ci(release): publish npm packages through changesets

[Makisuo]

What

• @changesets/cli + .changeset/config.json. Only public packages with publishConfig.access: public release: @maple-dev/effect-sdk, @maple-dev/browser, @maple-dev/alchemy. @maple/landing, @maple/clickhouse-cli and @effect-router/core are ignored; private workspaces are not versioned.
• .github/workflows/release.yml (changesets/action v2.1.2) on push to main: while changesets are pending, it keeps a "chore(release): version packages" PR open. Merging that PR publishes.
• scripts/publish-packages.ts is the publish step. changeset publish shells out to npm publish here, which would ship workspace:* / catalog: verbatim. The script builds with turbo, packs with bun pm pack (rewrites both), runs npm publish <tarball> --provenance, tags name@version and reports the tags to the action for GitHub releases. Dependents publish after their deps.

Usage

bunx changeset

Before merging

• @maple-dev/alchemy@0.2.0 is not on npm yet, so the first Release run after merge publishes it, with no changeset needed.
• Auth: add an NPM_TOKEN secret (used as a fallback) and/or configure npm trusted publishing for each package (repo MapleTechLabs/maple, workflow release.yml, environment npm-publish). A new package needs its first publish via token before trusted publishing can be set up.
• The Version PR is opened with GITHUB_TOKEN, so CI won't run on it automatically. Swap in a GitHub App token if that matters.

Maple review

🟢 Confidence 8/10 · likely safe to merge
Workspace scan, pack rewriting and dependency order I verified by running them; only the pinned action's inputs and credential precedence could not be checked offline.
_{quality 98/100 · 1 note · tests not needed · risk medium}

Adds a changesets release pipeline: release.yml keeps a Version Packages PR open on main and, on merge, publishes the three public npm packages through scripts/publish-packages.ts. The publish mechanics check out; one credential-ordering detail is worth fixing.

• release.yml runs changesets/action on main to open the Version Packages PR and publish on merge
• scripts/publish-packages.ts packs with bun pm pack and publishes tarballs with npm publish --provenance, then tags
• package.json gains changeset, changeset:version and changeset:publish scripts plus @changesets/cli
• .changeset/config.json releases only the three publishConfig.access: public packages

Before merge

• Secret · Add the NPM_TOKEN secret and/or configure npm trusted publishing for release.yml + environment npm-publish · .github/workflows/release.yml:42
• Manual · Confirm the pinned changesets/action commit resolves and that its inputs are version-script/publish-script
• Manual · On the first run, verify @maple-dev/alchemy@0.2.0 publishes (no changeset is needed for it)

Findings

🔵 Note · F1 · NODE_AUTH_TOKEN is always exported, so trusted publishing is never the credential

security · .github/workflows/release.yml:58

The token step (line 44) writes ~/.npmrc and this env passes NODE_AUTH_TOKEN to the action whenever the NPM_TOKEN secret exists, so npm authenticates with the long-lived token on every run and the OIDC trusted-publisher setup the description asks for is never exercised. Gate the token to the case that needs it (a package's first publish) rather than making it the default credential path.

Export `NODE_AUTH_TOKEN` (and write `~/.npmrc`) only behind a flag such as `vars.NPM_TOKEN_FALLBACK == 'true'`, or in a separate step that runs when the publish script reports an unauthenticated trusted-publisher failure.

What was checked

• bun pm pack rewrites workspace:* and catalog: in dependencies and devDependencies (ran it on packages/effect-sdk)
• The workspace scan finds all 48 manifests and the filter selects exactly the three public packages, ordering @maple-dev/alchemy after effect-sdk
• The ignored names (@maple/landing, @maple/clickhouse-cli, @effect-router/core) all exist and none is depended on by a published package

📝 Walkthrough

📝 Walkthrough

Walkthrough

The pull request adds Changesets configuration and commands, a script to select and publish eligible workspace packages, and a GitHub Actions workflow that runs release versioning and publishing.

Changes

Changesets release pipeline

Layer / File(s)	Summary
Changesets setup .changeset/README.md, .changeset/config.json, package.json	Adds contributor release instructions, Changesets configuration, and root commands for creating changesets, versioning packages, and publishing.
Package selection and publishing scripts/publish-packages.ts	Discovers eligible workspace packages, checks npm for their current versions, builds and packs pending packages, then publishes and tags them outside dry-run mode.
Release workflow .github/workflows/release.yml	Runs on matching pushes to main or manual dispatch. Installs dependencies and invokes the Changesets version and publish commands with the configured credentials and provenance settings.

Merge Risk: 🟡 Moderate · up to fca5e

The release pipeline can publish packages to npm but leave tags or GitHub releases missing, and rerunning it will not repair them. The first alchemy release will publish without a GitHub release unless a changelog entry is added. Resolve or accept these release-completeness gaps before merging.

- Line 71: Update the publish selection around isOnNpm(manifest) to reconcile
missing tags and releases for versions already published to npm, while ensuring
those versions are not republished. Keep tag and release recovery independent of
the npm publication decision so reruns can complete an interrupted release.
- Line 116: Add a valid 0.2.0 changelog entry for @maple-dev/alchemy so the
pinned Changesets action can create its GitHub release; alternatively, provide a
first-release path that skips the changelog requirement while preserving the
existing git-tag publication flow.

Maple review

🟢 Confidence 7/10 · likely safe to merge
The credential question behind the open finding is unresolved; the added code itself is a contained tag-recovery loop.
_{quality 98/100 · 1 note · tests not needed · risk medium}

Publishes the three public npm packages through changesets: a release workflow plus a publish script that builds, packs and tags. This head only adds tag recovery for versions already on npm, and is safe to merge once the npm credential question is settled.
