Note that you'll need to:
- Set up a [ReplicateHQ](https://replicate.com) account to get the `REPLICATE_API_TOKEN` env var.
- Set up an [Upstash](https://upstash.com) account to get the Upstash Redis env vars.
- Create a [Cloudflare R2 instance](https://www.cloudflare.com/lp/pg-r2/) and set up a [Cloudflare Worker](https://workers.cloudflare.com/) to handle uploads & reads (instructions below).
### Cloudflare R2 setup instructions
1. 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",
},
});
}
},
};
```
