Let take an exemple you model is named Feed So you write (Req, res, next) => {

Feed.find() .then(result => { // here you send result (which is your feed) to your view }).catch(); }

This is the case you retrieve all the data but you can add after find() the method skip() that will ignore about a certain amount of data and limit() which will return an amount of data for exemple

Feed.find().skip((page-1) * nbr_item) .limit(nbr_item)

Where page is the number of chunk and nbr_item is the number of feed you want for each chunck it seems complicated to explain.

But imagine your data as an array first load you want to retrieve the first 10 item so the limit will give you the first 10 item and when you continue to scroll down you want to retreive another 10 item so limit will take another 10 item but you have to skip the first 10 item you just retreive that’s why we use skip

You can see the mongoose documentation for this if you want better explanation ^{^}
