wrangler

To deploy a Cloudflare Worker, use the Wrangler CLI to build, configure bindings, and publish your edge application directly to the Cloudflare network. It automates deployment, development server management, and resource configuration.

Cloudflare Worker bindings connect your code to cloud resources like KV, R2, and D1. You configure these bindings in your wrangler configuration file, allowing the CLI to manage environment variables and resource access.

Yes, you can run a local dev-server for Cloudflare Workers to test code safely before deployment. Wrangler provides a local development workflow that simulates edge environments and tests resource bindings predictably.

Yes, the Wrangler CLI supports managing D1 and R2 resources alongside KV, Vectorize, Hyperdrive, Queues, and Workflows. It provides a unified interface to build, deploy, and maintain these attached storage resources.

The best way to manage multiple environments for Cloudflare Workers is defining environment configurations in your wrangler file. This allows you to maintain distinct settings, bindings, and compatibility dates for development and production deployments.

Setting a compatibility date when deploying Cloudflare Workers ensures the runtime applies specific backward-compatible features and behavioral flags. Wrangler uses this date to maintain predictable execution environments across updates.
