### `hooks`

Customization hooks allow you to modify various areas of the Admin UI to better suit your development needs. The `index.js` file at the given path should export a single config object containing your chosen hooks. All are optional. See [Customization](#customization) for available hooks.

If omitted, Keystone will look under `./admin-ui/` for a hooks config export.

#### Usage

```javascript title=index.js
new AdminUIApp({ hooks: require.resolve('./custom-hooks-path') });
```

### `isAccessAllowed`

This function takes the same arguments as a [shorthand imperative boolean](https://www.keystonejs.com/api/access-control#shorthand-imperative-boolean) access control. It must return either true or false.

> **Important:** If omitted, all users _with accounts_ will be able to access the Admin UI. The example below would restrict access to users with the `isAdmin` permission.

#### Usage

```js
new AdminUIApp({
  /*...config */
  isAccessAllowed: ({ authentication: { item: user, listKey: list } }) => !!user && !!user.isAdmin,
}),
```

## Customization

The following customization hooks are available. Each is a function that takes no arguments.

```javascript title=/custom-hooks-path/index.js
export default {
  customToast,
  itemHeaderActions,
  listHeaderActions,
  listManageActions,
  logo,

### `customToast`

Allows customising the content of toast notification when an item is updated or deleted.

The hook function receives a context variable containing an `item` key with the original item data, a `list` key that can be used to limit the scope of the hook, the original `message` as well as a `toastAction` that will be either 'update' or 'delete'. The function should return a React component.

```javascript
export default {
  customToast: ({ item, list, message }) => {
    // custom Toast for MyList
    if (list.key === 'MyList') {
      return (
        <div>
          <strong>My custom toast notification!</strong>
          {item && item._label_ ? <strong>{item._label_}</strong> : null}
        </div>
      );
    }
    // Default toast
    return (
      <div>
        {item && item._label_ ? <strong>{item._label_}</strong> : null}
        <div>{message}</div>
      </div>
    );
  },
};
```
