import {Pagination} from '@primer/react'
The pagination component only requires two properties to render: pageCount
, which is the total number of pages, and currentPage
, which is the currently selected page number (which should be managed by the consuming application).
<Pagination pageCount={15} currentPage={2} onPageChange={e => e.preventDefault()} />
However, to handle state changes when the user clicks a page, you also need to pass onPageChange
, which is a function that takes a click event and page number as an argument:
type PageChangeCallback = (evt: React.MouseEvent, page: number) => void
By default, clicking a link in the pagination component will cause the browser to navigate to the URL specified by the page. To cancel navigation and handle state management on your own, you should call preventDefault
on the event, as in this example:
<State default={1}>{([page, setPage]) => {const totalPages = 15const onPageChange = (evt, page) => {evt.preventDefault()setPage(page)}return (<Box borderWidth="1px" borderStyle="solid" borderColor="border.default" borderRadius={2} p={2}><Box>Current page: {page} / {totalPages}</Box><Pagination pageCount={totalPages} currentPage={page} onPageChange={onPageChange} /></Box>)}}</State>
To customize the URL generated for each link, you can pass a function to the hrefBuilder
property. The function should take a page number as an argument and return a URL to use for the link.
type HrefBuilder = (page: number) => string
<State default={'(nothing clicked yet)'}>{([lastUrl, setLastUrl]) => {const onPageChange = (evt, page) => {evt.preventDefault()setLastUrl(evt.target.href)}const hrefBuilder = page => {return `https://example.com/pages/${page}`}return (<Box borderWidth="1px" borderStyle="solid" borderColor="border.default" borderRadius={2} p={2}><Box>The last URL clicked was: {lastUrl}</Box><Pagination pageCount={15} currentPage={2} onPageChange={onPageChange} hrefBuilder={hrefBuilder} /></Box>)}}</State>
Two props control how many links are displayed in the pagination container at any given time. marginPageCount
controls how many pages are guaranteed to be displayed on the left and right of the component; surroundingPageCount
controls how many pages will be displayed to the left and right of the current page.
<PaginationpageCount={20}currentPage={10}marginPageCount={1}surroundingPageCount={2}onPageChange={e => e.preventDefault()}/>
The algorithm tries to minimize the amount the component shrinks and grows as the user changes pages; for this reason, if any of the pages in the margin (controlled via marginPageCount
) intersect with pages in the center (controlled by surroundingPageCount
), the center section will be shifted away from the margin. Consider the following examples, where pages one through six are shown when any of the first four pages are selected. Only when the fifth page is selected and there is a gap between the margin pages and the center pages does a break element appear.
<Box>{[1, 2, 3, 4, 5].map(page => (<PaginationpageCount={20}currentPage={page}marginPageCount={1}surroundingPageCount={2}onPageChange={e => e.preventDefault()}/>))}</Box>
To hide all the page numbers and create a simple pagination container with just the Previous and Next buttons, set showPages
to false
.
<State default={1}>{([page, setPage]) => {const totalPages = 10const onPageChange = (evt, page) => {evt.preventDefault()setPage(page)}return (<Box borderWidth="1px" borderStyle="solid" borderColor="border.default" borderRadius={2} p={2}><Box>Current page: {page} / {totalPages}</Box><Pagination pageCount={totalPages} currentPage={page} onPageChange={onPageChange} showPages={false} /></Box>)}}</State>
The following snippet shows the properties in the theme that control the styling of the pagination component:
export default {// ... rest of theme ...pagination: {borderRadius,spaceBetween,colors: {normal: {fg},disabled: {fg,border},hover: {border},selected: {fg,bg,border},active: {border},nextPrevious: {fg}}}}
