Awesome tutorial man. However, is there ANY possibility of you doing a cursor based pagination tutorial? The skip/limit method is good, but not exactly efficient.

Beautiful. All what I needed, explained in just 7 minutes.

For parallel calls, can you take the count of the collection in the first request and build the pages off that?

Great work. Question - are you not fetching all the books with your find() and then filtering down? If you had 10K books, would you not be bringing them all over and only showing 3? Thanks mate

@aiyushbedi 2 года назад

Thanks for amazing tuturial shaun. Can you also include other useful parameters for the frontend like totalRecords and totalPages which can be sent to create pagination?

@yumindev Год назад

I think you should skip (page -1 ) * booksPerPage. For example, if the page is 5 and there are 3 books per page, you should skip 4 * 3 , instead of 5 * 3.

@art1co Год назад

pages starts at 0 so the tutorial is correct, at page 0 you skip none 0*3, at page 1 you skip 1*3, ie the previues page only, and so on

@@art1co ok, I see. But that’s weird

@yahyarechaki9908 Год назад

I agree with you, that it should be (page -1) * booksPerPage, but in this case in this tutorial the pages starts at 0, so what he did is also right.

@agreensh 2 года назад

Isn't it normal to have the current page returned, and the total number of pages, in the response JSON?

@nir8924 2 года назад

you're correct. to do that you need to run the same query again but to get a document count instead of actually fetchin results and then you can calculate the total njmber of pages etc.

@agreensh 2 года назад

@@nir8924 No, not really. Api's that return paginated data are normally designed to return the current page, the total number of pages (and number of items per page, which you can normally pass as another parameter), as well as the actual data in one call.

@nir8924 2 года назад

@@agreensh that's exactly what I was saying. It is normal to get all the data like you say. But in order to get the total count of items / pages you need a second query to the database (not a second API call)

If I remember correctly from one your videos and correct me if I'm wrong but doesn't MongoDB return you by default a limit of documents? (around 100 I think) You said Mongo does not send you all the documents at once because this would put a strain on the bandwidth if your quantity of documents was huge.
