Edge-first TypeScript apps on Cloudflare Workers use wrangler to scaffold projects, Hono for request routing, and KV/D1/R2 bindings for storage. Start with a minimal wrangler.toml configuration, define bindings, and deploy globally distributed serverless functions with sub-100ms startup times.

Cloudflare Workers supports KV for key-value caching, D1 for SQL databases, and R2 for object storage. Each binding integrates into your TypeScript application through wrangler configuration, enabling persistent data across edge locations without external databases.

Yes, Hono integrates natively with Cloudflare Workers, providing lightweight request/response routing optimized for edge deployment. Hono examples in the Skill demonstrate patterns for handling stateless requests and coordinating with KV, D1, and Durable Objects.

Cloudflare Workers Queues enable asynchronous job processing without blocking edge responses. Queue messages persist and process reliably, complementing synchronous request handlers and storage bindings for distributed task workflows.

Durable Objects provide stateful coordination and real-time data consistency across edge requests. Use them for WebSocket coordination, rate limiting, or shared state that KV caching cannot handle, ensuring strict ordering and isolated state per object.

Testing patterns include unit tests for handler logic, mocking KV/D1/R2 bindings, and integration tests with local wrangler environments. The Skill covers test setup with TypeScript and validation against real edge deployment behavior.
