The Cloudflare Workers SDK repository is the home of Wrangler and several supporting packages that make it easier for developers to build, test, and deploy serverless applications on the Cloudflare Workers platform at global scale. It contains the command-line tooling, templates, local development environment, testing utilities, and build pipelines that integrate with the Workers runtime, so developers can write code in JavaScript, TypeScript, and other languages and push functions to Cloudflare’s edge network with minimal configuration. Wrangler enables developers to scaffold new projects, manage bindings (like KV, Durable Objects, and Secrets), preview code locally or remotely, and finally publish updates to production with a single command. The monorepo also includes tooling for simulating the Cloudflare runtime locally using Workerd, helping catch environment-specific bugs before deployment.
