Today we reached another milestone in our efforts to provide infrastructure and tools to make it easier for developers to use Google APIs: we have released the Google APIs Client Library for JavaScript in Alpha. This client library is the latest addition to our suite of client libraries, which already includes Python, PHP, and Java.
This compact and efficient client library provides access to all the Google APIs that are listed in the APIs Explorer. The client library is also flexible, supporting multiple browser environments including Chrome 8+, Firefox 3.5+, Internet Explorer 8+, Safari 4+, and Opera 11+. In addition, the JavaScript client library supports OAuth 2.0 authorization methods.
You can load the client library using the following script tag:
Loading an API and making a request is as easy as executing:<script src="https://apis.google.com/js/client.js?onload=CALLBACK"></script>
You can use the APIs Explorer to check all the methods available for an API, as well as the parameters for each method. For instance, use the above syntax with thegapi.client.load('API_NAME', 'API_VERSION', CALLBACK); // Returns a request object which can then be executed. // METHOD_NAME is only available once CALLBACK runs. var request = gapi.client.METHOD_NAME(PARAMETERS_OBJECT); request.execute(callback);
plus.activities.search method of the Google+ API to query activities:
To try this yourself, sign up in the Google APIs console or refer to the documentation on acquiring and using a developer key in the Google+ API.<!DOCTYPE html> <html> <head> </head> <body> <script type="text/javascript"> function init() { // Load your API key from the Developer Console gapi.client.setApiKey('YOUR_API_KEY'); // Load the API gapi.client.load('plus', 'v1', function() { var request = gapi.client.plus.activities.search({ 'query': 'Google+', 'orderby': 'best' }); request.execute(function(resp) { // Output title var heading = document.createElement('h4'); heading.appendChild(document.createTextNode( resp.title)); var content = document.getElementById('content'); content.appendChild(heading); // Output content of the response if (!resp.items) { content.appendChild(document.createTextNode( 'No results found.')); } else { for (var i = 0; i < resp.items.length; i++) { var entry = document.createElement('p'); entry.appendChild(document.createTextNode( resp.items[i].title)); content.appendChild(entry); } } }); }); } </script> <script src="https://apis.google.com/js/client.js?onload=init"></script> <div id="content"></div> </body> </html>
The Google APIs Client Library for JavaScript is currently in Alpha, which means that we are actively developing it, but wanted to get the library in your hands as soon as possible, and we welcome any feedback to make the code better. While you can use the current library to start writing code, you should use caution when writing production code as library code changes may break your application. We are working hard to upgrade this release to Beta and beyond soon, and to release even more client libraries.
To get started, visit the JavaScript Client Library documentation page. We also welcome your feedback, which you can provide using the JavaScript client group.
