cloudflare-workers

To deploy serverless functions at the edge, implement a fetch handler in src/index.ts, configure wrangler.toml, test locally with wrangler dev, and use Wrangler tooling to deploy. You must set a compatibility_date and nodejs_compat flags for the Cloudflare Workers runtime.

Cloudflare Workers edge apps support rich bindings including KV, R2, D1, Durable Objects, Queues AI, and Vectorize. These bindings integrate Cloudflare resources directly into your serverless functions for stateful storage and event-driven workflows.

Yes, Cloudflare Workers can run scheduled cron-based tasks, queue handlers, and email handling event-driven workflows. You configure these handlers within your project to execute automatically across Cloudflare's global network.

Local development and testing for Cloudflare Workers uses Miniflare and Vitest. After initializing your project and implementing the main entry file, run wrangler dev to test serverless functions locally before deploying.

Yes, running Cloudflare Workers requires Wrangler tooling for deployment and a specified compatibility_date in your configuration. You also need nodejs_compat flags to ensure your serverless code executes properly within the Cloudflare Workers runtime.

Deploying API endpoints as serverless functions at the edge using Cloudflare Workers reduces latency for globally distributed apps. This approach runs code closer to users across Cloudflare's global network with integrated resource bindings.
