Graphql schema formatter12/9/2023 To provide cursor-based pagination, there are some factors that must hold true. Seeing the GraphQL cursor-based pagination in action.Setting up the function to query the database.Setting up the Node.js development environment.Requirements for cursor-based pagination. ![]() GraphQL is a standardized API format that enables clients to explicitly ask for specific data. Then, we’ll demonstrate how to implement a basic Node.js GraphQL server which provides a paginated dataset using the Apollo Server package and a simple database access layer. In this article, we’ll explore the features and benefits of cursor-based pagination. This makes the API schema more complex compared to what would be needed for a simple list. Going back to the Facebook example, when a user scrolls through a newsfeed, new items - like a new reaction to a post - could enter the feed at any time. In contrast, it offers big advantages like supporting new data insertions into the dataset during paging. For example, clients cannot pass in a random page number in the middle of the dataset. ![]() There are a couple of constraints when using cursor-based pagination, compared to simple page based. The client uses these cursors to request data from the server and to specify a limit on the amount. Cursor-based pagination is a popular variant in which the server will send “cursors” representing the position of each item in the dataset. The resulting payloads are small and quick to resolve, translating to big performance gains for the client. Pagination is a strategy for addressing this issue it involves slicing the data a client asks for into “pages”. The HTTP response payload would be very large, resulting in slow page loading. It’s not practical for the web app or mobile app to ask the API server for all of the new items at once. ![]() Users have numerous friends and many items in their feed, such as shared posts, liked photos, etc. One example is Facebook, where users are continuously scrolling newsfeeds. The most interesting applications are those in which users interact with vast amounts of data.
