# Pip.WebUI Getting Started <br/> Step 9. Add map view to Nodes page

[Go to step 8](https://github.com/pip-webui/pip-webui-sample/blob/master/step8/) to show notifications.

### Create nodes map view

Rename **/src/nodes/nodes.html** file to **/src/nodes/nodes_tiles.html**

Create **/src/nodes/nodes_map.html** and copy there the content below:

```html
<pip-simple class="layout-row flex">
    <pip-location-map class="flex" pip-location-positions="location_points" pip-draggable="true" pip-stretch="true">
    </pip-location-map>
</pip-simple>
```

### Create nodes tiles controller

After we split the Nodes page into tile and map views the  **nodesController** will become a parent controller for all views.
Then we need to add two more child controllers **nodesTilesController** and **nodesMapController** for each view.

Make changes in the **/src/nodes/nodes.js** file. Change **nodesController** and add **nodesTilesController** and **nodesMapController**:

```javascript

thisModule.controller('nodesController', function($scope, $http, pipAppBar) {
    ...

    // Remove primary action configuration: pipAppBar.showLocalActions();

    ...
});

thisModule.controller('nodesTilesController', function($scope, $state, pipAppBar) {
    // Configure primary actions of each view inside controller
    
    // Show primary action to switch between views
    pipAppBar.showLocalActions([
        {
            name: 'nodes.map',
            icon: 'icons:location',
            callback: toMapView
        }
    ]);
    
    function toMapView() {
        $state.go('nodes.map');
    }
});

thisModule.controller('nodesMapController', function($scope, $state, pipAppBar) {
    // Configure primary actions of each view inside controller
    
    // Show primary action to switch between views
    pipAppBar.showLocalActions([
        {
            name: 'nodes.tiles',
            icon: 'icons:grid',
            callback: toTilesView
        }
    ]);
    
    function toTilesView() {
        $state.go('nodes.tiles');
    }
});

```

## Update application routes

Open **index.js** and in the configuration section make changes to nodes route states and default states:

```javascript
app.config(
        function (pipSideNavProvider, $mdIconProvider, pipAppBarProvider, pipAuthStateProvider, 
                  pipSettingsProvider, pipHelpProvider, $urlRouterProvider, pipRestProvider) {
        ...
        
        // Configure application route states
        pipAuthStateProvider
            .state('nodes', { // <--- Pay attention!
                url: '/nodes', // <--- Pay attention!
                template: '<ui-view class="layout-row flex w-stretch"></ui-view>', // <--- Pay attention!
                abstract: true, // <--- Pay attention!
                controller: 'nodesController', // <--- Pay attention!
                auth: true // <--- Pay attention!
            })
            .state('nodes.tiles', { // <--- Pay attention!
                url: '/tiles', // <--- Pay attention!
                controller: 'nodesTilesController', // <--- Pay attention!
                templateUrl: 'nodes/nodes_tiles.html' // <--- Pay attention!
            })
            .state('nodes.map', { // <--- Pay attention!
                url: '/map', // <--- Pay attention!
                controller: 'nodesMapController', // <--- Pay attention!
                templateUrl: 'nodes/nodes_map.html' // <--- Pay attention!
            })
            .state('events', {
                url: '/events',
                controller: 'eventsController',
                templateUrl: 'events/events.html',
                auth: true
            });
            
        // Configure default states
        pipAuthStateProvider.unauthorizedState('signin');
        pipAuthStateProvider.authorizedState('nodes.tiles'); // <--- Pay attention!
        
        $urlRouterProvider.otherwise(function ($injector, $location) {
            return $location.$$path === '' ? '/signin' : '/nodes/tiles'; // <--- Pay attention!
        });
         
        ...
});
```

After you make all the changes, rebuild the application. When you go to the nodes page and toggle the view, you shall see a map with positions of IoT nodes:

![IoT Nodes map view](artifacts/map_view.png)

Go to the events page, and then go back to the nodes. We continue to receive toast messages about incoming events. Fix this. Add this code into **eventsController**: 

```javascript
 thisModule.controller('eventsController', function($scope, $interval, $mdMedia, $http, pipAppBar, pipToasts) {

        ...

            $scope.$on('$destroy', function() {
                $interval.cancel(stopTime);
            });

        return;

        ...

    });
```

After you made all the changes, rebuild the application. Verify that the events reading stops after the transition to nodes.


### Continue

[Go to step 10](https://github.com/pip-webui/pip-webui-sample/blob/master/step10/) to add charts view to Events page.
