Requirements

- Angular.js

Installation

$3

This module is available as bower package, install it with this command:

``bash
$ bower install --save angular-google-gapi
`

it's also available as a npm package, install it with this command:

`bash
$ npm install --save angular-google-gapi
`

or you may download the latest release

`html

`


$3

`javascript
var app = angular.module('myModule', ['angular-google-gapi']);
`

Configuration

$3

add run() in root module

`javascript
app.run(['GApi', 'GAuth',
function(GApi, GAuth) {
var BASE = 'https://myGoogleAppEngine.appspot.com/_ah/api';
GApi.load('myApiName', 'v1', BASE).then(function(resp) {
console.log('api: ' + resp.api + ', version: ' + resp.version + ' loaded');
}, function(resp) {
console.log('an error occured during loading api: ' + resp.api + ', resp.version: ' + version);
});
}
]);
`


$3

add run() in root module

`javascript
app.run(['GAuth', 'GApi', 'GData', '$state', '$rootScope',
function(GAuth, GApi, GData, $state, $rootScope) {

$rootScope.gdata = GData;

var CLIENT = 'yourGoogleAuthAPIKey';
var BASE = 'https://myGoogleAppEngine.appspot.com/_ah/api';

GApi.load('myApiName','v1',BASE);
GApi.load('calendar','v3'); // for google api (https://developers.google.com/apis-explorer/)

GAuth.setClient(CLIENT)
// default scope is only https://www.googleapis.com/auth/userinfo.email
GAuth.setScope('https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/calendar.readonly');

// load the auth api so that it doesn't have to be loaded asynchronously
// when the user clicks the 'login' button.
// That would lead to popup blockers blocking the auth window
GAuth.load();

// or just call checkAuth, which in turn does load the oauth api.
// if you do that, GAuth.load(); is unnecessary
GAuth.checkAuth().then(
function (user) {
console.log(user.name + ' is logged in');
$state.go('webapp.home'); // an example of action if it's possible to
// authenticate user at startup of the application
},
function() {
$state.go('login'); // an example of action if it's impossible to
// authenticate user at startup of the application
}
);
}
]);
`

$3

`javascript
GApi.load('myApiName', 'v1', BASE)
.catch(function(api, version) {
console.log('an error occured during loading api: ' + api + ', version: ' + version);
});
`

Usage

$3

`javascript
app.controller('myController', ['$scope', 'GApi',
function myController($scope, GApi) {
GApi.execute('youApi', 'you.api.method.name').then(function(resp) {
$scope.value = resp;
}, function() {
console.log('error :(');
});
}
]);
`

$3

`javascript
app.controller('myController', ['$scope', 'GApi',
function myController($scope, GApi) {
GApi.execute('youApi', 'you.api.method.name', {param: value}).then(function(resp) {
$scope.value = resp;
}, function() {
console.log('error :(');
});
}
]);
`

$3

`javascript
app.controller('myController', ['$scope', 'GApi',
function myController($scope, GApi) {
GApi.executeAuth('youApi', 'you.api.method.name').then(function(resp) {
$scope.value = resp;
}, function() {
console.log('error :(');
});
}
]);
`

$3

`javascript
app.controller('myController', ['$scope', 'GApi',
function myController($scope, GApi) {
GApi.executeAuth('youApi', 'you.api.method.name', {param: value}).then(function(resp) {
$scope.value = resp;
}, function() {
console.log('error :(');
});
}
]);
`

$3

The login should be triggered by a user action, or you might run into issues with popup blockers. More information about this can be found in the Google APIs Client Library Documentation.

`javascript
app.controller('myController', ['$scope', 'GAuth', '$state',
function myController($scope, GAuth, $state) {
$scope.doSignup = function() {
GAuth.login().then(function(user) {
console.log(user.name + ' is logged in');
$state.go('webapp.home'); // action after the user have validated that
// your application can access their Google account
}, function() {
console.log('login failed');
});
};
}
]);
`

$3

Get user info after login is very simple

`javascript
app.controller('myController', ['$rootScope',
function myController($rootScope) {
console.log($rootScope.gdata.getUser().name);
}
]);
`

`html


{{gdata.getUser().name}}


`

User object:
- email
- picture (url)
- id (Google id)
- name (Google account name or email if don't exist)
- link (link to Google+ page)

Development

gulp is used to minify angular-google-gapi.js (using Uglify). Execute npm install (requires Node.js and npm) to install the required packages.

Run gulp to generate a minified version (angular-google-gapi.min.js). Note that this requires gulp to be installed globally (via npm install -g gulp`).
