# resumeServerSentEventsResponse

# Function: resumeServerSentEventsResponse()

```ts
function resumeServerSentEventsResponse<TOffset>(options): Response;
```

Defined in: [packages/ai/src/stream-to-response.ts:1005](https://github.com/TanStack/ai/blob/main/packages/ai/src/stream-to-response.ts#L1005)

Serve a resumable run from its durability log over Server-Sent Events, without
re-running the model. Use this in a `GET` handler so a reload or a second tab
can re-attach to an in-flight or finished run.

The adapter (`memoryStream(request)` / `durableStream(request)`) captures the
resume offset from the request. If there is none (no `Last-Event-ID` header
and no `?offset`), there is nothing to replay and this returns a 400.

## Type Parameters

## Returns

## Example

  return resumeServerSentEventsResponse({ adapter: memoryStream(request) });
}
```
