    "sizeBytes": 1570863,
    "parentId": "0B50DHrsuMkx6cWhrSXpTR1cyYW8"
  },
  {
    ...
  }
]

Configuration

In order to work, Google Picker needs to connect to the Google API using an application credentials (Api Key and client ID). For more information on how to create an application/project, please refer to https://developers.google.com/drive/web/. To do so, you'll need to configure the service.

Using configure(options)

angular.module('myApp', ['lk-google-picker'])

.config(['lkGoogleSettingsProvider', function (lkGoogleSettingsProvider) {

  lkGoogleSettingsProvider.configure({
    apiKey   : 'YOUR_API_KEY',
    clientId : 'YOUR_CLIENT_ID',
    scopes   : ['https://www.googleapis.com/auth/drive', 'another_scope', 'and_another'],
    locale   : 'ja',
    features : ['..', '..'],
    views    : ['..', '..']
  });
}])

Features

The Picker use the concept of views and features that allow you to customize it. The service provider allow you to enable some features to the Picker the same way you define your API Key or client ID (using either configure or setters).

angular.module('myApp', ['lk-google-picker'])

.config(['lkGoogleSettingsProvider', function (lkGoogleSettingsProvider) {
  lkGoogleSettingsProvider.features(['MULTISELECT_ENABLED', 'ANOTHER_ONE']);
}])

Default : MULTISELECT_ENABLED feature is use as default.

Please refer to https://developers.google.com/picker/docs/reference for more informations.

Views

Views are objects that needs to be instanciate using the namespace google.picker.*. That namespace is already defined in the core of the directive. In order to add views to your picker, all you need to do is to define the class that needs to be used :

angular.module('myApp', ['lk-google-picker'])

.config(['lkGoogleSettingsProvider', function (lkGoogleSettingsProvider) {
  lkGoogleSettingsProvider.views([
    'DocsUploadView()',
    'DocsView()'
  ]);
}])

NOTE : Views classes have some useful methods such as setIncludeFolders or setStarred (or any other methods available). In order to use them, just chain them to the class :

angular.module('myApp', ['lk-google-picker'])

.config(['lkGoogleSettingsProvider', function (lkGoogleSettingsProvider) {
  lkGoogleSettingsProvider.views([
    'DocsUploadView().setIncludeFolders(true)',
    'DocsView().setStarred(true)',
    'DocsView(google.picker.ViewId.FOLDERS).setSelectFolderEnabled(true)'
  ]);
}])

Default : DocsUploadView and DocsView are use as default.

Please refer to https://developers.google.com/picker/docs/reference for more informations.

Callbacks

The directive provide you 3 callbacks that you can use in order to work with the Picker.

onLoaded

This callback is triggered after the picker has been initialized and shown on the page.

angular.module('myApp', ['lk-google-picker'])

.controller('ExampleCtrl', ['$scope', function ($scope) {
  $scope.onLoaded = function () {
    console.log('Google Picker loaded!');
  }
}]);

<a href="javascript:;" lk-google-picker on-loaded="onLoaded()">Open my Google Drive</a>

onPicked

This callback is triggered after you select files and click on the select button from the Picker.

angular.module('myApp', ['lk-google-picker'])

.controller('ExampleCtrl', ['$scope', function ($scope) {
  $scope.onPicked = function (docs) {
    // docs contains the list of google documents object as shown above.
  }
}]);

<a href="javascript:;" lk-google-picker on-picked="onPicked">Open my Google Drive</a>

onCancel

This callback is triggered after the picker has been closed by clicking on the cancel button from the picker.

angular.module('myApp', ['lk-google-picker'])

.controller('ExampleCtrl', ['$scope', function ($scope) {
  $scope.onCancel = function () {
    console.log('Google picker close/cancel!');
  }
}]);

<a href="javascript:;" lk-google-picker on-cancel="onCancel">Open my Google Drive</a>

Demo

The demo version available at http://softmonkeyjapan.github.io/angular-google-picker/ can be found in the example folder. You will need a server in order to try it on your local machine. Since the Google Picker demo application is setup to allow origin from localhost:8000, I encourage you to use the python SimpleHTTPServer :

$ cd path/to/the/example/directory
$ python -m SimpleHTTPServer
Serving HTTP on 0.0.0.0 port 8000 ...

You should now be able to browse to localhost:8000 and see it in action from your localhost.
