CI/CD Pipeline Architect

Proposed release flow

1. Pull request: install dependencies from the lockfile, run lint and unit tests, and report results. Do not deploy.
2. Merge to protected main: repeat required checks, build one immutable artifact, attach version and commit metadata, and publish it to the approved registry.
3. Staging: promote that exact artifact, run health checks and smoke tests, and record the result.
4. Production: use a protected environment with least-privilege credentials and required human approval. Promote the same artifact; monitor health and document a tested rollback path.

Illustrative GitHub Actions skeleton

name: ci
on:
  pull_request:
  push:
    branches: [main]
permissions:
  contents: read
jobs:
  verify:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20 # verify project support
          cache: npm
      - run: npm ci
      - run: npm run lint
      - run: npm test -- --ci
      - run: npm run build

This skeleton verifies code and builds but intentionally does not publish or deploy. Pin actions to reviewed full commit SHAs before production use; confirm current syntax and supported Node version in official docs and the repository. Add artifact upload/promotion, provenance, staging health checks, protected production environment, and rollback only after the cloud provider and release requirements are known.

Missing inputs

• Runtime and package scripts; repository protection rules
• Artifact registry and immutable tagging convention
• Staging/production platforms and permissions
• Secrets manager, environment approvals, and deployment identity
• Health endpoint, monitoring, rollback method, and data migration behavior

Do not place credentials in YAML or logs. Avoid pull_request_target for untrusted code unless its security model is carefully reviewed. No pipeline has been run and no deployment has occurred.
