Setting up reverse proxies for microservices
Centralizing API authentication
Implementing request/response transformation
Managing traffic across backend services
Rate limiting and quota enforcement
API versioning and routing

Quick Start

Minimal working example:

# kong.yml - Kong Gateway configuration
_format_version: "2.1"
_transform: true

services:
  - name: user-service
    url: http://user-service:3000
    routes:
      - name: user-routes
        paths:
          - /api/users
          - /api/profile
    plugins:
      - name: rate-limiting
        config:
          minute: 100
          policy: local
      - name: jwt
        config:
          secret: your-secret-key
          key_claim_name: "sub"
      - name: cors
        config:
          origins:
            - "http://localhost:3000"
// ... (see reference guides for full implementation)

Best Practices

✅ DO

Centralize authentication at gateway level
Implement rate limiting globally
Add comprehensive logging
Use health checks for backends
Cache responses when appropriate
Implement circuit breakers
Monitor gateway metrics
Use HTTPS in production

❌ DON'T

Expose backend service details
Skip request validation
Forget to log API usage
Use weak authentication
Over-cache dynamic data
Ignore backend timeouts
Skip security headers
Expose internal IPs
