A Node to Workers Story

This post details the technical process of migrating a Node.js/Express application to Cloudflare Workers. It highlights the differences in request handling between Express (using `request` and `response` objects) and Workers (using `fetch` events and `respondWith` with `Response` objects). The author also describes creating a custom `app` object within the Worker to mimic Express routing logic and demonstrates how to replace `response.json()` with `new Response(JSON.stringify(...), { headers: { 'Content-Type': 'application/json' } })`. Furthermore, it showcases the removal of unnecessary configuration files like `Procfile`, `credentials.json`, and `package.json` by leveraging Workers' built-in capabilities and the ability to import libraries via webpack.
