GitHub Actions CI/CD Pipeline Generator

Generate a GitHub Actions CI/CD workflow for the following project:

Project type: web app Language/Framework: {{framework}} Package manager: npm Deployment target: Vercel Branch strategy: main + feature branches

The workflow should:

1. Trigger on push to main and on pull requests
2. Test — Run linting, type checking, and test suite
3. Build — Production build with caching for faster runs
4. Docker — Build and push Docker image (if applicable)
5. Deploy — Deploy to Vercel on successful main branch builds
6. Notifications — Comment on PR with build status

Include:

• Proper secrets management (list what secrets are needed)
• Caching strategy for dependencies
• Matrix testing if multiple Node/Python versions are needed
• Concurrency settings to cancel outdated runs
• Environment-specific variables (staging vs production)

Add comments explaining each step for team members unfamiliar with GitHub Actions.
