Plan for bindings

[jokull]

Is there a roadmap for making bindings available (D1, R2, etc.) in RSC? On my blog I'm doing direct drizzle stuff in RSC.

Thanks for filing this! Good news: bindings should already work in server components today via the cloudflare:workers module import.

import { env } from "cloudflare:workers";

export default async function Page() {
  const result = await env.DB.prepare("SELECT * FROM posts").all();
  return <div>{JSON.stringify(result)}</div>;
}

We just verified that the build pipeline handles this correctly. The @cloudflare/vite-plugin runs the RSC environment in workerd, where cloudflare:workers is a native module. vinext doesn't interfere with the resolution. The import gets properly externalized in the production build so workerd resolves it at runtime.

No custom worker entry needed, no special configuration. Just import { env } from "cloudflare:workers" in any server component and your D1, R2, KV, AI, etc. bindings should be available.

The existing examples all predate this pattern (they use the older fetch(request, env) approach with custom worker entries), which is probably why it wasn't obvious that this works. We'll update the examples to show the modern pattern.

Are you seeing different behavior? If cloudflare:workers isn't resolving for you, let us know what error you're hitting and we can dig in.

Just didn't know about cloudflare:workers env shim! Thank you. An example will point us all in the right direction.
