Recently I was looking around for a quick way to implement infinite scrolling and found the jscroll plugin for jquery.
The problem was that all the examples online were broken and they all seemed to copy and paste from each other which made it difficult to figure out what worked. Finally I got something working and just wanted to post the options that I was using for anyone else that needs help with it.
Depending on your framework, create an endpoint that returns a response containing your content and a link to the next item to load (a link element) at the end. It is important that this response contains the HTML necessary for the item you are rendering and is not just a JSON response.
