What problem does it solve? Configuring and deploying Cloudflare Workers involves many CLI flags, binding types, and config fields that change frequently, and outdated knowledge leads to broken deployments, leaked secrets, or misconfigured environments. ## Core Features & Use Cases - Worker Deployment & Versioning: Deploy to staging and production with the version-then-promote pattern (wrangler versions upload then wrangler deployments create) for rolling updates and instant rollbacks. - Binding & Secret Management: Configure KV, R2, D1, Vectorize, Hyperdrive, Workers AI, Queues, and other bindings in wrangler.jsonc, and manage secrets safely via wrangler secret put. - Type Generation & Local Dev: Generate TypeScript types with wrangler types and test locally with wrangler dev, with explicit guidance on v4 local-mode defaults. - Use Case: You are setting up a new Worker with a D1 database and KV cache. The skill guides you to declare bindings in wrangler.jsonc, set a recent compatibility date, generate types, test locally, and deploy to staging before production. ## Quick Start Use the wrangler skill to set up a new Cloudflare Worker project with a D1 binding and deploy it to staging.
