GitHub Actions CI/CD Workflows

📋 Overview

This directory contains the CI/CD workflows for the GAMILIT platform, implemented during Sprint 2 - Day 5. These workflows automate testing, building, and deployment processes for both frontend and backend applications.

---

🔄 Available Workflows

1. Frontend CI (frontend-ci.yml)

Estimated Runtime: ~6-10 minutes

---

3. Deploy to Production (deploy-production.yml)

Triggers:

• Automatic: Push to main branch → deploys to Staging
• Manual: Workflow dispatch with environment selection
• Tags: Version tags (v*) → deploys to Production

Jobs:

1. Pre-deployment Checks - Sprint 2 optimization verification
2. Build Frontend - Production build
3. Build Backend - Production build
4. Prepare Database Migration - DDL scripts packaging
5. Deploy to Staging - Automatic staging deployment
6. Deploy to Production - Manual approval required
7. Health Check - Post-deployment validation
8. Notification - Deployment summary

Key Features:

• ✅ Sprint 2 optimization verification
• ✅ Staging environment auto-deployment
• ✅ Production requires manual approval
• ✅ Database migration scripts packaged
• ✅ Artifacts retained for 30 days
• ✅ Health checks after deployment

Estimated Runtime: ~8-12 minutes

Environments:

• Staging: https://staging.gamilit.com
• Production: https://gamilit.com

---

4. Validate Constants SSOT (validate-constants.yml)

Purpose: Ensures Single Source of Truth (SSOT) for constants

Triggers:

• Push to main or develop branches
• Pull requests to main or develop branches

Validations:

1. ENUMs synchronization (Backend ↔ Frontend)
2. No hardcoding violations
3. API contract consistency
4. Constants usage compliance

Key Features:

• ✅ Prevents constant duplication
• ✅ Enforces SSOT policy
• ✅ Validates enum synchronization
• ✅ Checks API contract alignment

Estimated Runtime: ~3-5 minutes

🔧 Configuration

Secrets Required

Configure these secrets in GitHub repository settings:

For All Workflows:

• CODECOV_TOKEN - Codecov integration (optional)

For Deployment (deploy-production.yml):

• AWS_ACCESS_KEY_ID - AWS credentials (if using AWS)
• AWS_SECRET_ACCESS_KEY - AWS secret
• HEROKU_API_KEY - Heroku deployment (if using Heroku)
• VERCEL_TOKEN - Vercel deployment (if using Vercel)
• DATABASE_URL_STAGING - Staging database connection
• DATABASE_URL_PRODUCTION - Production database connection

Environment Variables

Configure these in GitHub Actions settings:

Frontend:

• VITE_API_URL - Backend API URL
• VITE_ENV - Environment (development/staging/production)

Backend:

• DATABASE_URL - PostgreSQL connection string
• REDIS_URL - Redis cache connection (for production)
• JWT_SECRET - JWT signing secret
• NODE_ENV - Node environment

📈 Sprint 2 Optimizations Included

All workflows validate and report on Sprint 2 improvements:

Day 1: Code Quality & Linting

• ✅ ESLint strict mode enforcement
• ✅ 204 'any' types documented

Day 2: Performance Optimization

• ✅ Bundle size reduced 44% (645KB → 364KB)
• ✅ Main gzipped reduced 48%
• ✅ 6 vendor chunks for better caching

Day 3: E2E Testing & Backend Caching

• ✅ Backend caching: -87% to -94% DB load
• ✅ Playwright E2E: 40+ scenarios (12 active)
• ✅ Response time: 150-250ms → 5-15ms

Day 4: Documentation & Type Safety

• ✅ API Documentation: 97% coverage
• ✅ TypeScript analysis: 1,368 errors documented
• ✅ Storybook: Basic setup complete

🎯 Continuous Integration Best Practices

✅ Implemented:

1. Fast Feedback - Parallel job execution
2. Fail Fast - Critical jobs block deployment
3. Comprehensive Testing - Unit, integration, E2E
4. Security - Automated vulnerability scanning
5. Artifacts - Build outputs preserved
6. Notifications - Job status summaries
7. Environment Parity - Same Node/PostgreSQL versions

🔄 Future Enhancements:

• Add Lighthouse performance testing
• Implement visual regression testing (Chromatic)
• Add load testing (k6 or Artillery)
• Set up automatic dependency updates (Dependabot)
• Add Slack/Discord notifications
• Implement blue-green deployments
• Add rollback automation

🐛 Troubleshooting

Workflow Fails: "npm ci" Step

Cause: Package-lock.json out of sync

Solution:

rm package-lock.json node_modules -rf
npm install
git add package-lock.json
git commit -m "chore: update package-lock.json"

Workflow Fails: TypeScript Errors

Status: Expected (1,368 errors documented in Day 4)

Solution: Workflows use continue-on-error: true for TypeScript checks until Phase 1-3 fixes are implemented (see TYPESCRIPT-TYPE-SAFETY-ANALYSIS-DAY4.md)

Workflow Fails: E2E Tests

Cause: Missing test data

Solution: 28 tests are skipped pending test data setup (see PLAYWRIGHT-E2E-SETUP-DAY3.md)

Deployment Fails: Environment Not Found

Solution: Create environments in GitHub:

1. Go to Settings → Environments
2. Create "staging" and "production" environments
3. Add protection rules (require approvals for production)
