pagination

Infinite scroll can be done with plain HTML + Turbo Frames. Render a “next page” frame with loading: :lazy so Turbo fetches it when it enters the viewport. No JS required, and it degrades gracefully.

Clients love predictable pagination. Provide Link headers and totals when feasible. This snippet shows a small helper that generates RFC5988-ish link headers for JSON endpoints.

Turbo Frames can implement infinite scrolling without a JS router. I render the first page normally and append a “next page” frame at the bottom with loading: :lazy. When the user scrolls and the frame enters view, Turbo fetches the next page automati

Traditional offset-based pagination becomes unreliable and slow for large datasets when records are frequently inserted or deleted—users can miss items or see duplicates across pages. Cursor-based pagination solves this by using an opaque token that e

If you sort by a non-unique column (score, created_at), pagination can “skip” or “duplicate” records. Always add a secondary unique key like id for deterministic ordering.

OFFSET gets slower as tables grow and becomes inconsistent under writes. Keyset pagination is stable and fast: paginate by (created_at, id) cursor. This is a common “senior Rails” upgrade for activity feeds.

Offset pagination (LIMIT/OFFSET) is fine until it isn’t: it gets slow on large tables and it produces weird duplicates when rows are inserted between pages. For APIs I prefer cursor pagination with an opaque token. The token encodes the last seen (cre

Lists are fundamental to iOS apps, displaying scrollable collections efficiently. SwiftUI's List or ScrollView with LazyVStack renders items on-demand. I add pull-to-refresh with the .refreshable modifier, calling async refresh logic. For infinite scr

I use PageNumberPagination for simple, bookmark-friendly pagination and CursorPagination when data changes frequently (prevents duplicate/missing items between pages). Creating a custom pagination class lets me control page_size, page_size_query_param

Spring Data provides elegant pagination and sorting mechanisms. Pageable interface defines page number, size, and sort parameters. Page wraps results with metadata—total elements, total pages, current page. Sort defines ordering by multiple properties

Sometimes a frame is great for partial navigation, but sometimes you explicitly want a full-page visit. Pagination is a common case: when the page number changes, I often want the URL to update and the browser history to behave normally. You can tell

Pagination divides large datasets into pages, improving performance and UX. Eloquent's paginate() method returns a paginator with data and metadata. The links() method renders pagination UI. I customize per-page counts with paginate(50). Simple pagina
