It's basically a really fun little library that allows you to add a notification bubble to your favicons. I started to play around with the code provided on Github and got up and running in no time.
Using this simple example will give you something like this:
As you can see the above example is really simple and not really real world. It's using a timer to update the icon every second. After messing around with the example on the site, I wondered how I could apply the notifications to this site. If I checked the last blog entry that they read on this site, then I would be able to notify them if there were any new blog post's since their last visit. It's just a fun experiment really!
If you are a regular visitor to the site, you might notice that you have a notification next to the favicon. This is how I went about it.
This site is coded using MVC2 so I added a new variable on my Controller to the TempData called "TotalPageCount". This is then added to a hidden field on the page that I can use to read the value from.
Oh, there is also a gotcha when dealing with dynamic favicons. I started running through the example on the TinyCon site and came across this error when debugging:
It took me a while to solve this, but thanks to this post on StackOverflow I managed to solve it. Basically, you need to have the favicon in your own domain or it will cause a security exception. Once that is in place, you should be able to get up running without any problems.
If the browser doesn't support dynamic favicons, it will gracefully fall back and update the title with a number instead. This blog post is really a bit of fun, but I can see a load of uses for the helpful little library.
