Inquiries regarding real-time alerts and notifications

Just curious, I am wondering about the creation of those notifications/alerts (for example on platforms like twitchalerts, commonly used by livestreamers). Are they typically coded in JavaScript/AJAX or another language?

Is there a specific framework for that language that can simplify the process of creating similar features?

Lastly, is it necessary to use a separate listening application, or is there a way to integrate this functionality directly into a webpage?

I appreciate any insights. For context, I am new to web programming and eager to understand how these functionalities are developed for educational purposes.

Thanks once again! :)

Answer №1

There are two different methods to achieve this: One option is to incorporate a simple html/css element that pops up within the page to provide information. There are numerous libraries available for this purpose. For example, you can visit:

Pros: Easy to implement Cons: Notification won't display if the browser or tab is closed.

The other approach involves utilizing the desktop notifications API: https://www.html5rocks.com/en/tutorials/notifications/quick/

Pros: Notifications will still show even if the browser is closed Cons: Requires user permission, limited browser support http://caniuse.com/#search=notification
