This article provides an introduction to bundling Service Worker scripts using Webpack. It explains that while a simple Service Worker script can be written as a single file, larger scripts may require JavaScript's module system. However, Cloudflare only accepts a single JS file for Service Workers. The author demonstrates how to bundle your Service Worker with TypeScript and Webpack using an example weather-fetching worker. They also explain how to use off-the-shelf solutions on npm to handle routing logic in the worker script. Finally, they emphasize that Webpack is a powerful tool for bundling Cloudflare Service Workers.
