How can I implement pagination while sorting data in mongodb?

edit

To implement pagination while sorting data in MongoDB, you can use the skip() and limit() methods together with the sort() method.

Here's an example:

const perPage = 10; // number of items to display per page
const pageNumber = 1; // current page number

const sortOrder = { timestamp: -1 }; // sort by timestamp in descending order

const items = await db.collection('my_collection')
  .find({})
  .sort(sortOrder)
  .skip((pageNumber - 1) * perPage) // skip items from previous pages
  .limit(perPage) // display only the items for the current page
  .toArray();

console.log(items);

In this example, we're sorting the data by the timestamp field in descending order, skipping the items from previous pages, and limiting the number of items to display per page using the skip() and limit() methods. We're also using the toArray() method to get the array of documents.

To implement pagination, you need to modify the pageNumber variable accordingly, based on the user's input or the current page number.
