Pulse by Jeffikus is an example plugin for the Heartbeat API! It is a starting point for building your Heartbeat functionality into your WordPress powered application or plugin.

The plugin basically does the following:

• Outputs console data for a logged in user - the object will state that the user is logged in - Console Screenshot
• Outputs console data for a non logged in user - the object will state that the user is not logged in - Console Screenshot

WordPress.org is where your finished plugins should go (assuming they are free) - while this plugin doesn't actually perform any function or add value on its own - you need to make the magic happen :-)

The main reason for hosting it on Github is so you can easily fork it for your own projects, and send pull requests for updates/suggestions!

There are loads of possibilities;

• Chat applications,
• Notifications on the frontend,
• Manipulation of the DOM based on events happening in the CMS backend,
• And generally all types of (near) real-time functionality.
