Accessing Cloudflare bindings in Astro

When deploying Astro to Cloudflare Workers, you can access KV, D1, R2, and other bindings directly using the cloudflare:workers module.

import { env } from "cloudflare:workers";

export const prerender = false;

export async function GET(): Promise<Response> {
	const kv = env.LIKES as KVNamespace;
	const value = await kv.get("my-key");
	return new Response(value);
}

The bindings are defined in your wrangler.jsonc as usual:

{
	"kv_namespaces": [
		{
			"binding": "LIKES",
			"id": "your-namespace-id"
		}
	]
}

No need for Astro.locals.runtime.env or any adapter-specific API. The cloudflare:workers import works in any server endpoint or middleware as long as prerender is set to false.

See the Astro Cloudflare adapter docs for more details.
