Cloudflare Workers Bible

1. FOUNDATIONS OF CLOUDFLARE WORKERS

Cloudflare Workers revolutionize how developers build and deploy applications by running code directly on Cloudflare's global edge network. This section delves into the foundational aspects of Cloudflare Workers, providing a comprehensive understanding of their definition, benefits, core concepts, supported languages, infrastructure, and various use cases.

1.1 Definition of Cloudflare Workers

Cloudflare Workers are serverless applications that execute JavaScript, TypeScript, Python, Rust, and WebAssembly (WASM) code directly on Cloudflare’s edge servers. Operating at over 300 data centers worldwide, Workers intercept HTTP requests and responses, allowing developers to manipulate, enhance, or respond to web traffic in real-time.

Note: Before proceeding with the installation, it's recommended to perform some post-installation steps on your server. You can find the details in this gist.

Run the following command to uninstall all conflicting packages:

for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done

Set up Docker's apt repository.

	* - Run `npm run dev` in your terminal to start a development server
	* - Open a browser tab at http://localhost:8787/ to see your worker in action
	* - Run `npm run deploy` to publish your worker
	*
	* Bind resources to your worker in `wrangler.toml`. After adding bindings, a type definition for the
	* `Env` object can be regenerated with `npm run cf-typegen`.
