Seo Master present to you: The last few weeks, Google Chrome's developer tools have become much more useful. Besides benefiting from the work the WebKit team has done to improve Web Inspector (our developer tools are partially based on Web Inspector), we also recently released the heap profiler and the timeline tab in Google Chrome's Developer Channel.

With the heap profiler you can now take a snapshot of the JavaScript heap at any point in time. A heap snapshot helps you understand memory usage, and by comparing snapshots you can also follow memory usage over time. You will find the heap profiler in the profiles tab along with the sample-based CPU profiler.

The new timeline view gives you a complete overview of where time is spent when loading a web app. All events -- ranging from loading resources over parsing and executing JavaScript to calculating styles and repainting -- are plotted on a timeline.

Besides these product improvements, we've tried to make the Google Chrome Developer tools easier to find and understand by putting together mini site with tutorials and videos.



To take our newest release for a spin, get Google Chrome from the Developer Channel and you'll automatically be brought up to date. We welcome your feedback and your contributions to improve developer tools in WebKit and Google Chrome even more.

This week we launched a campaign to keep the Internet #freeandopen, ahead of a meeting of government agencies next week that could increase censorship and regulation of the Internet. We believe that Internet policies should be discussed and decided by the people who use it, not just governments. You can go to the site to learn more and find out what you can do. You can also watch Google Developers Live next Tue., Wed., and Thu. for live Hangouts on this topic. Your opinion matters!



Speaking of matter, researchers are eyeing data from the Large Hadron Collider for evidence of a new form of matter that has been theorized to exist but never seen. The new matter is a kind of gluon called color-glass condensate. Scientists noted that some wacky particles unexpectedly showed quantum entanglement when they traveled in the same direction after collisions. A new state of matter is a possible explanation.

Finally, take a look at this video of erupting lava from the Kilauea Volcano flowing into the ocean. You can also see a webcam view of the caldera, including some brave people watching from a safe distance. Maybe they’ll wave!


Each Friday on this blog we depart from the usual developer topics and present fun and interesting stuff that’s not necessarily related to writing code. Sometimes we even veer into an important topic, like the #freeandopen program mentioned in this post.

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:

<script src="https://apis.google.com/js/client.js?onload=CALLBACK"></script>

Loading an API and making a request is as easy as executing:

gapi.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);

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 the plus.activities.search method of the Google+ API to query activities:

<!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>

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.

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.


Brendan O'Brien is a Software Engineer for the Browser Client group at Google. Prior to working on JavaScript APIs he was a frontend engineer for iGoogle. He is passionate about JavaScript and enjoys building web applications.

Antonio Fuentes is a Product Manager for the Google API Infrastructure group. He has experience launching products in the cloud computing, infrastructure, and virtualization space.
