Go to Cloudflare and create an [R2 bucket](https://www.cloudflare.com/lp/pg-r2/). 2. Create a [Cloudflare Worker](https://workers.cloudflare.com/) using the code snippet below. 3. Bind your worker to your R2 instance under **Settings > R2 Bucket Bindings**. 4. For extra security, set an `AUTH_KEY_SECRET` variable under **Settings > Environment Variables** (you can generate a random secret [here](https://generate-secret.vercel.app/)). 5. Replace all instances of `images.extrapolate.workers.dev` in the codebase with your Cloudflare Worker endpoint.

Cloudflare Worker Code

```ts // Check requests for a pre-shared secret const hasValidHeader = (request, env) => { return request.headers.get("X-CF-Secret") === env.AUTH_KEY_SECRET; }; function authorizeRequest(request, env, key) { switch (request.method) { case "PUT": case "DELETE": return hasValidHeader(request, env); case "GET": return true; default: return false; } } export default { async fetch(request, env) { const url = new URL(request.url); const key = url.pathname.slice(1); if (!authorizeRequest(request, env, key)) { return new Response("Forbidden", { status: 403 }); } switch (request.method) { case "PUT": await env.MY_BUCKET.put(key, request.body); return new Response(`Put ${key} successfully!`); case "GET": const object = await env.MY_BUCKET.get(key); if (object === null) { return new Response("Object Not Found", { status: 404 }); } const headers = new Headers(); object.writeHttpMetadata(headers); headers.set("etag", object.httpEtag); return new Response(object.body, { headers, }); case "DELETE": await env.MY_BUCKET.delete(key); return new Response("Deleted!"); default: return new Response("Method Not Allowed", { status: 405, headers: { Allow: "PUT, GET, DELETE", }, }); } }, }; ```
