Separation of web application logic?

Question

Angular

Let's say there is an online store in angular, we get a list of all products from the server in json format and all application logic is implemented on the client (pagination, sorting, etc.), but what if we have 100,000 products or more? What is the correct way to get data from the server?

Answer 1

No way. Pagination and filters need to be processed on the server with such volumes.

Answer 2

request not all products, but 30, on the second page request 30 products after 30, on the third page request 30 products after 60.
Like so
select * from products limit 60,30
