cloudflare-workers-author

What problem does it solve?

This Skill prevents Cloudflare Workers teams from shipping brittle, runtime-breaking code by guiding end-to-end Worker authoring with correct bindings, routing, testing, and gradual production rollouts.

Core Features & Use Cases

• Production-grade Worker workflow: covers adding new Workers and extending existing ones with a consistent, incident-resistant process.
• Bindings and storage decision matrix: helps you choose between KV, R2, D1, Durable Objects, Hyperdrive, Queues, Workers AI, and Vectorize based on consistency, data shape, and workload needs.
• Correct edge runtime patterns: enforces Module Workers syntax, safe request routing (native URL/switch vs Hono), and Worker-specific pitfalls like secret leakage and canceled fire-and-forget promises.
• Testing and deployment guardrails: standardizes testing with @cloudflare/vitest-pool-workers and rollout strategy using wrangler versions for gradual traffic splits and smoke tests.

Quick Start

Ask the AI to help you build a new production-grade Cloudflare Worker in TypeScript by selecting the right storage binding, scaffolding the project, adding Hono or native routing, wiring tests with @cloudflare/vitest-pool-workers, and deploying with wrangler versions gradual rollout.
