# Method name: afterQuery(item: object, context: HookContext)

# Method package: wixDataHooks

# Method menu location: wixDataHooks --> afterQuery

# Method Link: https://dev.wix.com/docs/velo/events-service-plugins/data/hooks/wix-data-hooks/after-query.md

# Method Description:

A hook that is triggered after a `find` operation, for each of the items in the query results.

The `afterQuery()` hook runs when:

 + The [`find`](wix-data.WixDataQuery.html#find) function is called.
 + An action is performed on a dataset that retrieves items from the collection.
 + The collection is viewed in the CMS.
 + An item is exported from the collection.


 The hook runs once for each item in the collection.

 Return an object or a Promise that resolves to an object from the `afterQuery()`
 function. The returned object will be used as the result of the call to the
 [`find`](wix-data.WixDataQuery.html#find) function instead of the actual item
 found in the collection. If returning a Promise, the object is used as the
 result, whether the Promise is fulfilled or rejected.

 If the returned value is of the wrong type, the value is ignored.

 A rejected Promise also calls the [`onFailure()`](#onFailure) hook if it has
 been registered.

> **Note:**
> We recommend implementing `afterQuery()` with in-memory operations only. Don't use network calls such as REST API requests
> or other wix-data operations, as these can lead to timeouts and issues loading collection data.



# Method Code Examples:

*** Note: do not assume any prop names or enum values other than the ones in the example.

## An afterQuery hook

```javascript
// In data.js

export function myCollection_afterQuery(item, context) {
  let hookContext = context;  // see below

  // some changes to the received item

  return item;
}

/*
 * hookContext:
 *
 * {
 *   "collectionName": "myCollection",
 *   "userId":         "f45jf8d2-grkj-2opd-4ovk-9rfj4wo5tvj3",
 *   "userRole":       "siteOwner"
 * }
 */
```

## Change the item returned by `find()` using an afterQuery hook

```javascript
// In data.js

export function myCollection_afterQuery(item, context) {
  let hookContext = context;  // see below

  // add a full_name property to the item being returned
  item.full_name = item.first_name + " " + item.last_name;

  return item;
}

/*
 * hookContext:
 *
 * {
 *   "collectionName": "myCollection",
 *   "userId":         "f45jf8d2-grkj-2opd-4ovk-9rfj4wo5tvj3",
 *   "userRole":       "siteOwner"
 * }
 */
```
