Collect Cloudflare Workers Logs to Serverless Kafka

This tutorial provides a step-by-step guide on how to collect logs from Cloudflare Workers and send them to a Serverless Kafka setup using Upstash. It begins with setting up a Kafka cluster and topic through the Upstash Console or CLI, followed by configuring a project using Wrangler 2 for deployment, which includes initializing a new project directory, setting up package management, and creating necessary configuration files. The tutorial then details how to update the JavaScript code in `src/index.js` to send logs to Kafka using a webhook URL and offers options for using Upstash Kafka SDK or REST API. Testing and deployment instructions are provided, including local testing with `wrangler dev` and publishing the function to Cloudflare with `wrangler publish`, with guidance on verifying log collection in Kafka using a curl command.
