Before-and-after architecture comparing Next.js Server Actions with a dedicated Hono API Server layer, both serving web and mobile clients across multi-cloud backends. The legacy approach couples frontend and backend via direct Server Actions and fetch calls, while the migrated pattern introduces Hono as a dedicated API gateway with JWT middleware, enabling better separation of concerns and mobile-first support. This migration unlocks consistent API contracts, improved testability, and unified authentication across web and native clients. Fork this diagram on Diagrams.so to customize the middleware stack, add rate limiting, or adjust your cloud provider mix. The pattern demonstrates how lightweight frameworks like Hono reduce boilerplate compared to heavier API frameworks while maintaining enterprise-grade security.
