Pagination With GraphQL
Explore how to implement pagination in GraphQL by creating a backend query that returns data in parts using skip and limit parameters. Understand how to design the resolver with Mongoose methods and prepare your API for large datasets. This lesson helps you build a more scalable and efficient data fetching strategy for applications.
We'll cover the following...
We’ve already implemented a few queries that fetch multiple products from our backend. However, in all the previous cases, these queries returned all the objects available on the backend. This isn’t very practical!
As soon as our application gets any traction, it’ll collect thousands of products in its database. Fetching and returning thousands of objects on every request is hardly scalable, so if we plan to make our application usable, we need to update our API to return results in a piecemeal fashion.
This is called pagination and in this lesson, we’ll explore how to implement it on both the backend and the frontend of our application. We’ll implement a new query that allows us to get products from the server chunk by chunk. Then, we’ll update the frontend to use the new query instead of the allProducts query that we’re using now.
We’ll split these steps into three lessons. First, we’ll see how we can implement pagination on the ...
