# Abort breaks resumable streams

## Issue

When using `useChat` with `resume: true` for stream resumption, the abort functionality breaks. Closing a tab, refreshing the page, or calling the `stop()` function will trigger an abort signal that interferes with the resumption mechanism, preventing streams from being properly resumed.

```tsx
// This configuration will cause conflicts
const { messages, stop } = useChat({
  id: chatId,
  resume: true, // Stream resumption enabled
});

// Closing the tab will trigger abort and stop resumption
```

## Background

When a page is closed or refreshed, the browser automatically sends an abort signal, which breaks the resumption flow.

## Current limitations

We're aware of this incompatibility and are exploring solutions. **In the meantime, please choose either stream resumption or abort functionality based on your application's requirements**, but not both.

### Option 1: Use stream resumption without abort

If you need to support long-running generations that persist across page reloads:

```tsx
const { messages, sendMessage } = useChat({
  id: chatId,
  resume: true,
});
```

### Option 2: Use abort without stream resumption

If you need to allow users to stop streams manually:

```tsx
const { messages, sendMessage, stop } = useChat({
  id: chatId,
  resume: false, // Disable stream resumption (default behavior)
});
```
