v1.1.0 Implementation Complete ✅

Summary

Successfully implemented npx cerber init command for instant project setup!

Branch: feat/init-gh-actions

Commit: d9303e6

🎯 What Was Built

1. CLI Infrastructure

  • src/cli/init.ts - Main init command logic
  • src/cli/contract-parser.ts - YAML CERBER_CONTRACT parser
  • src/cli/template-generator.ts - File generation engine
  • src/cli/types.ts - TypeScript interfaces

2. CLI Command

  • bin/cerber - Extended with init subcommand
  • Flags: --mode, --force, --dry-run, --no-husky, --no-workflow, --no-health

3. Reusable GitHub Actions Workflow

  • .github/workflows/cerber-gatekeeper.yml
  • workflow_call type for multi-repo reuse
  • Post-deploy health validation with configurable fail conditions

4. Generated Files (Examples)

Files created by npx cerber init in client projects:

  • CERBER.md (with CERBER_CONTRACT)
  • scripts/cerber-guardian.mjs
  • .husky/pre-commit
  • src/cerber/health-checks.ts
  • src/cerber/health-route.ts
  • .github/workflows/cerber.yml
  • .github/CODEOWNERS (team mode only)

5. Tests

  • src/cli/contract-parser.test.ts - Unit tests for parser
  • test/smoke-test.sh - Manual smoke test script

6. Documentation

  • README.md - Updated with 30-second Quick Start
  • CHANGELOG.md - Complete v1.1.0 changelog
  • USAGE_GUIDE.md - Comprehensive usage instructions

7. Package Configuration

  • package.json - Version bumped to 1.1.0
  • .npmignore - Templates excluded from npm package (generated on-demand)

📋 CERBER_CONTRACT Format

Machine-readable YAML embedded in CERBER.md:

## CERBER_CONTRACT
version: 1
mode: dev  # solo | dev | team

guardian:
  enabled: true
  schemaFile: BACKEND_SCHEMA.ts
  hook: husky
  approvalsTag: ARCHITECT_APPROVED

health:
  enabled: true
  endpoint: /api/health
  failOn:
    critical: true
    error: true
    warning: false

ci:
  provider: github
  branches: [main]
  requiredOnPR: true
  postDeploy:
    enabled: false
    waitSeconds: 90
    healthUrlVar: CERBER_HEALTH_URL
    authHeaderSecret: CERBER_HEALTH_AUTH_HEADER

🚀 How It Works

First Run (No CERBER.md)

npx cerber init
# Creates CERBER.md template
# Exits with instructions to customize

Second Run (With CERBER.md)

npx cerber init
# Parses CERBER_CONTRACT
# Generates all files based on mode
# Updates package.json
# Shows next steps

Modes

Solo Mode

  • Guardian pre-commit validation
  • Basic health checks (optional)
  • Simple CI workflow

Dev Mode (Default)

  • Guardian with required imports
  • Health check endpoints
  • GitHub Actions CI/CD
  • Optional post-deploy health gates

Team Mode

  • Everything from Dev mode
  • CODEOWNERS protection
  • Required PR reviews
  • Post-deploy health validation (enabled by default)

🐛 Known Limitations (By Design)

  1. Guardian runner is MVP - Basic validation, full rules in v1.2.0
  2. No doctor command - Planned for v1.2.0
  3. No branch protection API - Manual setup with instructions
  4. Templates not in npm package - Generated on-demand (saves space)

📞 Support

If issues arise:

  1. Check USAGE_GUIDE.md
  2. Run with --dry-run first
  3. Review generated files manually
  4. Open GitHub Discussion for questions

Status: ✅ READY FOR MERGE AND RELEASE

Next Action: Merge to main and publish to npm
