# Method name: afterCount(count: number, context: HookContext)

# Method package: wixData

# Method menu location: wixData --> Hooks --> afterCount

# Method Link: https://dev.wix.com/docs/velo/apis/wix-data/hooks/after-count.md

# Method Description:

A hook that is triggered after a `count()` operation.

The `afterCount()` hook runs when:

 + The [`count()`](wix-data.WixDataQuery.html#count) function is called.
 + The collection is viewed in the CMS.


 Return a number or a Promise that resolves to number from the `afterCount()`
 function. The returned number will be used as the result of the call to
 [`count()`](wix-data.WixDataQuery.html#count) instead of the actual count of
 items found in the collection. If returning a Promise, the number 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.



# Method Code Examples:

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

## An afterCount hook

```javascript
// In data.js

export function myCollection_afterCount(count, context) {
  let hookContext = context;  // see below

  // some change to the received count

  return count;
}

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

## Change the number returned by `count()` using an afterCount hook

```javascript
// In data.js

export function myCollection_afterCount(count, context) {
  let hookContext = context;  // see below

  // return a value higher than the actual item count
  count += 5;

  return count;
}

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