How we built an open-source SEO tool using Workers, D1, and Queues

Prospector is an open-source application built on top of Cloudflare's Workers platform, which enables developers to build serverless applications that can be run globally with low latency. The application uses several tools from the Cloudflare suite, including D1 (a serverless SQL database), Queues (a task queue for background processing), and Pages (a platform for deploying static websites). Prospector is designed to track keyword matches on websites by periodically scraping their content using Puppeteer. When a new match is found, the application sends an email notification to the user with details about the match. The application can be easily deployed and managed using wrangler, Cloudflare's command-line tool for Workers. It uses TypeScript for development, which provides improved type safety and editor support. Overall, Prospector showcases how developers can use Cloudflare's suite of tools to build powerful and scalable applications that require real-time data processing and background task execution.
