# <MergeQueue>

> Queue child tasks so at most maxConcurrency run; defaults to single-lane.

```ts theme={null}
// Props
import { MergeQueue } from "smithers-orchestrator";

type MergeQueueProps = {
  id?: string;
  maxConcurrency?: number;  // default: 1
  skipIf?: boolean;
  children?: ReactNode;
};
```

```tsx theme={null}
<MergeQueue maxConcurrency={2}>
  {items.map((it, i) => (
    <Task key={i} id={`t${i}`} output={outputs.outputC}>{{ value: i }}</Task>
  ))}
</MergeQueue>
```

## Notes

* Innermost group determines the effective cap for its descendants.
* Tasks outside the queue are unaffected by its limit.
