Usage

Basic Example (Offset-based pagination)

importReactCarouselQueryfrom'react-carousel-query'import'react-carousel-query/styles.css'// Required for stylesconstgetData=async({ offset, limit })=>{constresponse=awaitfetch(`https://api.example.com/items?offset=${offset}&limit=${limit}`)const{ data }=awaitresponse.json()return{total: data.total,// Total number of items availableitems: data,// Each item must have an `id` property (string | number)}}constApp=()=>(<ReactCarouselQueryrenderItem={({ item })=><imgsrc={item.imgSrc}alt={item.name}/>}getData={getData}/>)

Cursor-based pagination

To use cursor-based pagination, return nextCursor in your response. The component auto-detects the pagination mode:

constgetData=async({ cursor, limit })=>{consturl=cursor
? `https://api.example.com/items?cursor=${cursor}&limit=${limit}`
: `https://api.example.com/items?limit=${limit}`constresponse=awaitfetch(url)const{ data, nextCursor, totalCount }=awaitresponse.json()return{items: data,
nextCursor,// null when there are no more pagestotal: totalCount,// optional - will be inferred from items if not provided}}
