The text discusses pagination, which is the process of splitting long lists of data into smaller chunks. Pagination is a common issue in modern applications and can be approached in different ways. The author covers three main types of pagination: numbered pages, sequential pages, and infinite scroll. Numbered pages are often used for mostly static content where items don't move between pages frequently, but they have drawbacks such as skipping or displaying the same item twice. Sequential pages are more suitable for dynamic content where users can navigate through different sections, and infinite scroll is a popular approach used by many social media platforms. The author also introduces cursor-based pagination, which is a generic specification for paginated data that allows clients to efficiently fetch new items without being constrained by old-school concepts like page numbers. Finally, the text discusses Relay cursor connections, a specification for GraphQL servers that exposes paginated data in a predictable way, and concludes that there is no single best solution for pagination, but rather a tradeoff between simplicity of implementation and fancy user experience and performance benefits.
