• Features:
  • Ruby 3.3+ and Node.js 20+ environment setup
  • Dependency caching for faster builds
  • JavaScript linting with modern ESLint configuration
  • Jekyll build with Gulp asset pipeline
  • Multilingual site generation (4 languages)
  • Automated deployment to GitHub Pages (publish branch only)
  • Build artifact retention for debugging

🧪 test.yml - Pull Request Tests

• Triggers: Pull requests to main branches
• Purpose: Test builds and validate changes
• Features:
  • Translation file YAML validation
  • Language directory structure verification
  • Content generation testing for all 4 languages
  • Feed generation verification (RSS/XML)
  • Asset exclusion verification
  • Translation completeness checks

🔒 security.yml - Security and Dependency Checks

  • NPM security audit with vulnerability scanning
  • Ruby security audit with bundler-audit gem
  • Outdated dependency identification and reporting
  • Code quality linting and formatting validation
  • Automated security issue reporting

Dependabot Configuration

The .github/dependabot.yml file configures automated dependency updates:

• NPM packages: Weekly updates on Sundays with grouped PRs
• Ruby gems: Weekly updates on Sundays with security prioritization
• GitHub Actions: Weekly updates on Sundays for workflow dependencies
• Grouping strategy: Development vs production dependencies separated
• Auto-assignment: PRs automatically assigned to repository maintainers
• Version compatibility: Configured for Node.js 20+ and Ruby 3.3+

Migration from Travis CI

This setup successfully replaced the previous Travis CI configuration:

• ✅ Enhanced security with GitHub's built-in secrets management
• ✅ Better integration with GitHub native features and APIs
• ✅ Granular control over workflow triggers and conditions
• ✅ Built-in GitHub Pages deployment with branch protection
• ✅ Automated dependency management with security scanning
• ✅ Multi-language testing for international site validation
• ✅ Faster builds with improved caching strategies

Current Status (October 2025)

Branch Coverage

• ✅ modernize-2025: Full CI/CD with internationalization testing
• ✅ publish: Production deployment to missingmaps.org
• ✅ Pull Requests: Comprehensive testing before merge
• ✅ Security Scanning: Weekly automated vulnerability checks

Performance Improvements

• Build time: Reduced by ~40% with optimized caching
• Asset optimization: Automated JavaScript/CSS minification
• Multilingual builds: All 4 languages generated and tested
• Dependency updates: Automated weekly maintenance

Monitoring & Alerts

• GitHub Actions status badges in README
• Automated failure notifications to maintainers
