Release on Tag (Token-based)

# .github/workflows/release.yml
name: Release
on:
  push:
    tags: ['v*']

jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: pnpm/action-setup@v4
      - uses: actions/setup-node@v4
        with:

          cache: pnpm
          registry-url: https://registry.npmjs.org
      - run: pnpm install
      - run: pnpm build
      - run: pnpm publish --access public --no-git-checks
        env:
          NODE_AUTH_TOKEN: ${{ secrets.NPM_TOKEN }}

Release on Tag (OIDC - Recommended)

No NPM_TOKEN needed. Uses GitHub OIDC for tokenless auth with provenance.

name: Release
permissions:
  id-token: write
  contents: write
  actions: read
on:
  push:
    tags: ['v*']

jobs:
  wait-for-ci:
    runs-on: ubuntu-latest
    steps:
      - uses: lewagon/wait-on-check-action@v1.3.4
        with:
          ref: ${{ github.sha }}
          check-name: ci
          repo-token: ${{ secrets.GITHUB_TOKEN }}
          wait-interval: 10

  release:
    needs: wait-for-ci
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0
      - uses: pnpm/action-setup@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 24  # Required: npm 11.5.1+
          cache: pnpm
          registry-url: https://registry.npmjs.org
      - run: pnpm install
      - run: pnpm build
      - run: pnpm dlx changelogithub
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
      - run: pnpm publish --access public --no-git-checks --provenance

OIDC Setup Steps

1. Open https://www.npmjs.com/package/<PACKAGE_NAME>/access
2. Scroll to "Publishing access" section
3. Click "Add GitHub Actions" under Trusted Publishers
4. Fill: Owner, Repository, Workflow file (release.yml), Environment (empty)
5. Click "Add"

OIDC Requirements

1. Node.js 24+ (npm 11.5.1+ required - Node 22 has npm 10.x which fails)
2. Permissions: id-token: write
3. Publish flag: --provenance
4. package.json: must have repository field
5. npm 2FA: "Require 2FA or granular access token" (allows OIDC)

Troubleshooting

Monorepo Matrix

jobs:
  test:
    strategy:
      matrix:
        package: [core, utils, cli]
    steps:
      - uses: actions/checkout@v4
      - uses: pnpm/action-setup@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 22
          cache: pnpm
      - run: pnpm install
      - run: pnpm --filter ${{ matrix.package }} test

Concurrency Control
