What are Cloudflare Workers?

Cloudflare Workers is platform for developers that provides a serverless execution environment. It allows you to create entirely new applications or augment existing ones without configuring or maintaining infrastructure.

For example, here is a simple Cloudflare Workers app that responds “Hello World” to any HTTP request:

export default {
    async fetch(request: Request): Promise<Response> {
        return new Response("Hello world");
    },
};

Cloudflare Workers is very powerful, you can even deploy Rust program to the Cloudflare Workers via WASM.
