New GData JavaScript library enables full read and write access for your mashups

By Dion Almaer, Google Developer Programs

I am really excited to see the release of the GData JavaScript Client Library for Calendar that allows you to do a lot more with Calendar GData mashups.

Developers have been able to work with our GData feeds from JavaScript for over a year, but only in a read-only capacity. There are plenty of mashups that can be done that way, but what if you want an application that ties into personal content? What if you would like to write an Ajax client that can create, update, or delete entries as well as read it?

Now you can. This release allows you full read-write access to Google Calendar from JavaScript. Instead of requiring server-side proxies to do this for you, AuthSub is fully supported from within the pure JavaScript client.

You can login by doing something similar to:

function logMeIn() {
 scope = "http://www.google.com/calendar/feeds";
 var token = google.accounts.user.login(scope);
}

function setupMyService() {
 var myService =
   new google.gdata.calendar.CalendarService('exampleCo-exampleApp-1');
 logMeIn();
 return myService;
}

I got to sit down with Jun Yang, who worked on this code, and got his take on the new library:



Armed with this new functionality, I can only imagine how the mashups will become richer. I can't wait to see them!

Introducing Calendar Gadgets

By Michael Bolin, Google Calendar Team

You've seen them on iGoogle, in IBM WebSphere Portal, and now you can find them in your favorite online calendar -- that's right, now we're supporting Gadgets in Google Calendar! If you're a Scorpio like me, you can add this gadget that lets you check your horoscope from your calendar (don't worry, all the signs of the zodiac are supported). And if astrology isn't your thing, how about games? This Sudoku gadget was created by Alex Komoroske, one of our interns on the Docs & Spreadsheets team. If you add the gadget, you'll see that the daily puzzles get harder throughout the week.

Finally, if you like to keep up on celebrity birthdays, the birthday reminder will show you who you are idolizing that day:



But you don't have to be a Googler to create a Calendar Gadget -- we have put together new documentation to help you get your favorite Gadgets into Calendar. If you are itching to write some code, then you can use GData or ICAL to add some fancy Calendar Gadget events to your calendar. But if you're out of Red Bull and don't have the time for a late-night hacking session, then you may want to try our new "of-the-day" Calendar Gadget wizard, which makes it easy to take an existing Google Gadget and have it show up once a day, every day, just like the Horoscope and Sudoku Gadgets do.

Let us know how your experiences with Calendar Gadgets are going in the Google Calendar GData API developer forum.
