🚦 API Gateway with TuskLang & Go

Introduction

API gateways are the front door to your services. TuskLang and Go let you build gateways with config-driven routing, auth, rate limiting, and more—no more NGINX spaghetti.

Key Features

- Routing and load balancing - Authentication and authorization - Rate limiting - Request/response transformation - Caching - Service mesh integration - API versioning - Security and monitoring

Example: API Gateway Config

[gateway]
routes: @file.read("routes.yaml")
auth: @go("gateway.Authenticate")
rate_limit: @go("gateway.RateLimit")
caching: @cache("5m", "api_responses")
metrics: @metrics("gateway_latency_ms", 0)

Go: Gateway Example

package gateway
import (
  "net/http"
)
func Authenticate(r *http.Request) bool {
  // Auth logic
}
func RateLimit(r *http.Request) bool {
  // Rate limiting logic
}

Routing & Load Balancing

- Use TuskLang config to define routes - Go handles HTTP proxying and balancing

Authentication & Rate Limiting

- Implement in Go, wire up in config

Request/Response Transformation

[transform]
request: @go("gateway.TransformRequest")
response: @go("gateway.TransformResponse")

Caching

- Use @cache for response caching

Service Mesh Integration

- Integrate with Istio, Linkerd, etc. via Go SDKs

API Versioning

- Route based on version in config

Security & Monitoring

- Use @env.secure for secrets - Monitor with @metrics

Best Practices

- Centralize all gateway config in TuskLang - Use Go for custom logic - Monitor everything

Troubleshooting

- Check Go logs for routing/auth errors - Use @metrics for real-time health

Conclusion

TuskLang + Go = API gateways that are powerful, flexible, and easy to manage.
