# cx.google.core
[![Build Status](https://travis-ci.org/ef-ctx/cx.google.core.svg?branch=master)](https://travis-ci.org/ef-ctx/cx.google.core)


Provides a wrapper around Google Client JSApi.


## Getting Started

This part describes how to load the cx.google.* modules and bootstrap a angular 1.x application.
Add **cx.google.core** to you project.

Via npm:

```bash
$ npm install --save cx.google.core
```

`cx.google.core` uses SystemJS as module loader. This means that we need to do a few things with our AngularJS application to get it to load in the correct order.

#### 1. Add these modules to your html `(index.html)`

```html
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<script src="node_modules/systemjs/dist/system.js"></script>
<script src="node_modules/cx.google.core/bundles/cx.google.core.js"></script>
```

#### 2. Prevent angular from manually bootstrap the application. Remove any `ng-app` directive from you page.

#### 3. Tell `SystemJS` about `cx/google/core`.

```html
<script>
System.config({
  packages: {
    'cx/google/core': {
      defaultExtension: 'js',
    }
  }
});
</script>
```

#### 4. Load cx.google.core and cx.google.drive then manually bootstrap your application.

```html
<script>
  Promise.all([
    System.import('cx/google/core')
  ])
    .then(function (modules) {
      var core = modules[0]; // the cx.google.core module.
      core.Client.bootstrap(); // Load the google api client.

      angular.element(document).ready(function() {
          angular.bootstrap(document, ['cx.google.drive.example']);
      });
    });
</script>
```

### Example use with a angular 1.x service to that consumes `cx.google.*` 

Check if a user is authorized or not. If not logg them in.

```javascript

angular.module('ng.cx.google.core', [
])

.service('google', [
  '$window',
  function ($window) {
   'use strict';

   this.Auth = $window.cx.google.Auth;
   this.client = $window.cx.google.client;
  }
]);

angular.module('myApp', [
  'ng.cx.google.core'
])

.controller('MainCtrl', [
  'google',
  function (google) {
    'use strict';
    // Read here how to create your clientId https://developers.google.com/drive/v3/web/quickstart/js
    var _auth = new google.Auth('YOUR_CLIENT_ID');

    _auth.checkAuth()
      .then(loggedIn)
      .catch(notLoggedIn);

    function loggedIn() {
      console.log('Logged in');
    }

    function notLoggedIn() {
      console.log('not logged in');
      // Let's authorize user.
      _auth.authorize()
        .then(loggedIn)
    }
  }
])
```
