How to implement cursor-based pagination in GraphQL
Blog post from LogRocket
Applications interacting with large datasets, such as Facebook, benefit significantly from pagination strategies to manage data efficiently, reducing payload sizes and improving performance. Cursor-based pagination, a popular approach, uses cursors to represent data positions, allowing clients to request specific data portions and accommodate new data additions during paging. Unlike simple page-based pagination, cursor-based pagination imposes certain constraints, such as the inability to randomly access pages, but it offers advantages in handling dynamic datasets. The text explores setting up a Node.js GraphQL server using the Apollo Server package to implement cursor-based pagination, focusing on creating a schema according to the Relay GraphQL Cursor Connections Specification. This setup involves a unique sequential column in the dataset to ensure reliable ordering and a shared schema design, facilitating client-server communication. The article also provides a practical example involving a Star Wars-themed dataset and discusses the importance of monitoring GraphQL requests in production using tools like LogRocket for enhanced debugging and performance tracking.
