Manual Deployment Steps

Backend Deployment (Railway)

Create Railway Account: Go to railway.app
Connect GitHub: Link your GitHub repository
Create Project: Select "Deploy from GitHub repo"
Configure Root: Set backend as the root directory
Set Environment Variables: Add production environment variables
Deploy: Railway automatically builds and deploys

Frontend Deployment (Netlify)

Create Netlify Account: Go to netlify.com
New Site from Git: Connect your GitHub repository
Build Settings:
- Base directory: frontend
- Build command: npm run build
- Publish directory: frontend/build
Environment Variables: Set React environment variables
Deploy: Netlify builds and deploys automatically

🧪 Testing Your Deployment

Automated Health Checks

The health check script validates:

Frontend Accessibility: Site loads correctly
Backend Health: API server responds
API Endpoints: All routes work properly
Authentication: API key validation
Rate Limiting: Request throttling works
CORS Configuration: Cross-origin requests allowed

Manual Testing Checklist

Frontend loads without errors
All pages navigate correctly
API endpoints respond with correct data
Authentication flows work
Error handling displays properly
Mobile responsiveness works
Performance is acceptable (< 3s load time)

Load Testing

bash

# Test API performance
curl -w "@curl-format.txt" -o /dev/null -s "https://your-api.railway.app/api/quests?api_key=demo_key_12345"

# Test concurrent requests
for i in {1..10}; do curl -s "https://your-api.railway.app/health" & done; wait

🎯 Production Optimizations

Frontend Optimizations

Code Splitting: Automatic with Create React App
Asset Compression: Gzip compression enabled
CDN Caching: Static assets cached globally
Bundle Analysis: Use npm run analyze to check bundle size
Progressive Web App: Service worker for offline functionality

Backend Optimizations

Production Dependencies: Only install production packages
Compression Middleware: Gzip response compression
Request Logging: Structured logging for monitoring
Health Checks: Automated uptime monitoring
Database Connection Pooling: Efficient database connections

Security Configurations

HTTPS Enforcement: Automatic SSL certificates
Security Headers: Helmet.js for security headers
CORS Configuration: Restrict allowed origins
Rate Limiting: Prevent API abuse
Environment Variable Security: No secrets in code

📊 Monitoring and Analytics

Application Monitoring

javascript

// Frontend error tracking
import * as Sentry from '@sentry/react';

Sentry.init({
  dsn: process.env.REACT_APP_SENTRY_DSN,
  environment: process.env.REACT_APP_ENVIRONMENT
});

// Backend error tracking
const Sentry = require('@sentry/node');

Sentry.init({
  dsn: process.env.SENTRY_DSN,
  environment: process.env.NODE_ENV
});
