I want next and previous data

Firstly, you need to determine what is "next" and what is "previous".

I assume you have some sorting on your MongoDB query? Perhaps you are sorting by date? Maybe you have a field set up for some sort of sort index/priority? Somehow, you need a deterministic ordering for your list.

I recommend linking to your blog articles by ID. So, when you load the data for one article, also get the IDs for the previous and next articles by querying MongoDB for them. Then in your template, you can make a regular anchor element:

<a href="/articles/<<article-id-goes-here>>">Next</a>

If you want to style them like buttons, you can use CSS to set a border or background:

a.button {
  border: 0.1em solid #777;
  background: #aaa;
}
