Building a scalable Cloudflare Workers API requires a three-tier architecture using Hono-based routing for the API layer, separate business logic, and a data layer connecting to D1 or Supabase for secure, low-latency edge workloads.

Yes, you can use Supabase instead of D1 for data access in Cloudflare Workers. The data layer supports both D1 for SQLite at the edge and Supabase for PostgreSQL to accommodate flexible storage requirements.

The best way to test serverless edge logic on Cloudflare Workers is using Jest-driven testing to ensure full coverage across the API, business logic, and data layers within your edge application architecture.

Yes, this Cloudflare Workers setup supports LLM integrations and AI streaming through the Vercel AI SDK V6+, enabling deterministic LLM interactions directly within your edge-optimized backend services.

Optimizing edge caching for sub-50ms API responses on Cloudflare Workers involves structuring your backend with a Hono-based API layer and edge computation logic tuned specifically for globally distributed serverless workloads.

You should avoid a three-tier serverless architecture for edge computing if your application does not require complex data access patterns, secure multi-tenant separation, or integration with D1 and Supabase, as the structure adds unnecessary overhead for simple tasks.
