Merges query-option fragments into one options object.

**Signature:**

```typescript
export function mergeQuery(queryOptions?: any, ...merge: any[]): any;
```

## Parameters


| Parameter | Type | Description |
| --- | --- | --- |
| queryOptions | any | _(Optional)_ Target, mutated in place. |
| merge | any\[\] | Fragments to merge, in order; falsy ones are skipped. |


**Returns:**

any

The same `queryOptions` object.

## Exceptions

TypeError when a fragment's property type conflicts with the target's.

## Remarks

Per property: an absent property is taken as-is, arrays are unioned with duplicates dropped, objects are shallow-assigned, and anything else is overwritten by the later value. A fragment whose property type disagrees with what is already there — a scalar where an array sits, say — throws rather than guessing.

MUTATES and returns `queryOptions`, so pass a fresh object unless sharing is what you want.
