Pagination
Pagination is an interface that allows navigating between pages that contain split information, instead of being shown on a single page.
Properties
Features
- Full keyboard navigation.
- Optimized for screen readers.
Installation
To use the pagination machine in your project, run the following command in your command line:
npm install @zag-js/pagination @zag-js/react # or yarn add @zag-js/pagination @zag-js/react
npm install @zag-js/pagination @zag-js/vue # or yarn add @zag-js/pagination @zag-js/vue
npm install @zag-js/pagination @zag-js/vue # or yarn add @zag-js/pagination @zag-js/vue
npm install @zag-js/pagination @zag-js/solid # or yarn add @zag-js/pagination @zag-js/solid
This command will install the framework agnostic pagination logic and the reactive utilities for your framework of choice.
Anatomy
To set up the pagination correctly, you'll need to understand its anatomy and how we name its parts.
Each part includes a
data-partattribute to help identify them in the DOM.
Usage
First, import the pagination package into your project
import * as pagination from "@zag-js/pagination"
The pagination package exports two key functions:
machine— The state machine logic for the pagination widget.connect— The function that translates the machine's state to JSX attributes and event handlers.
You'll also need to provide a unique
idto theuseMachinehook. This is used to ensure that every part has a unique identifier.
import * as pagination from "@zag-js/pagination" import { useMachine, normalizeProps } from "@zag-js/react" import { data } from "./data" function Pagination() { const [state, send] = useMachine( pagination.machine({ id: "1", count: data.length }), ) const api = pagination.connect(state, send, normalizeProps) return ( <div> {api.totalPages > 1 && ( <nav {...api.rootProps}> <ul> <li> <a href="#previous" {...api.prevTriggerProps}> Previous <span className="visually-hidden">Page</span> </a> </li> {api.pages.map((page, i) => { if (page.type === "page") return ( <li key={page.value}> <a href={`#${page.value}`} {...api.getItemProps(page)}> {page.value} </a> </li> ) else return ( <li key={`ellipsis-${i}`}> <span {...api.getEllipsisProps({ index: i })}>…</span> </li> ) })} <li> <a href="#next" {...api.nextTriggerProps}> Next <span className="visually-hidden">Page</span> </a> </li> </ul> </nav> )} </div> ) }
import * as pagination from "@zag-js/pagination" import { normalizeProps, useMachine } from "@zag-js/vue" import { defineComponent, h, Fragment, computed } from "vue" import { data } from "./data" export default defineComponent({ name: "Pagination", setup() { const [state, send] = useMachine( pagination.machine({ id: "1", count: data.length }), ) const apiRef = computed(() => pagination.connect(state.value, send, normalizeProps), ) return () => { const api = apiRef.value return ( <div> {api.totalPages > 1 && ( <nav {...api.rootProps}> <ul> <li> <a href="#previous" {...api.prevTriggerProps}> Previous <span class="visually-hidden">Page</span> </a> </li> {api.pages.map((page, i) => { if (page.type === "page") return ( <li key={page.value}> <a href={`#${page.value}`} {...api.getItemProps(page)}> {page.value} </a> </li> ) else return ( <li key={`ellipsis-${i}`}> <span {...api.getEllipsisProps({ index: i })}> … </span> </li> ) })} <li> <a href="#next" {...api.nextTriggerProps}> Next <span class="visually-hidden">Page</span> </a> </li> </ul> </nav> )} </div> ) } }, })
<script setup> import * as pagination from "@zag-js/pagination" import { normalizeProps, useMachine } from "@zag-js/vue" import { computed } from "vue" import { data } from "./data" const [state, send] = useMachine(pagination.machine({ id: "1", count: data.length })) const api = computed(() => pagination.connect(state.value, send, normalizeProps)) </script> <template> <nav v-if="api.totalPages > 1" v-bind="api.rootProps"> <ul> <li> <a href="#previous" v-bind="api.prevTriggerProps"> Previous <span class="visually-hidden">Page</span> </a> </li> <li v-for="(page, i) in api.pages" :key="page.type === 'page' ? page.value : `ellipsis-${i}`" > <span v-if="page.type === 'page'"> <a :href="`#${page.value}`" v-bind="api.getItemProps(page)"> {{page.value}} </a></span > <span v-else> <span v-bind="api.getEllipsisProps({ index: i })">…</span> </span> </li> <li> <a href="#next" v-bind="api.nextTriggerProps"> Next <span class="visually-hidden">Page</span> </a> </li> </ul> </nav> </template>
import * as pagination from "@zag-js/pagination" import { normalizeProps, useMachine } from "@zag-js/solid" import { createMemo, createUniqueId, For } from "solid-js" import { data } from "./data" function Pagination() { const [state, send] = useMachine( pagination.machine({ id: createUniqueId(), count: data.length }), ) const api = createMemo(() => pagination.connect(state, send, normalizeProps)) return ( <div> {api().totalPages > 1 && ( <nav {...api().rootProps}> <ul> <li> <a href="#previous" {...api().prevTriggerProps}> Previous <span class="visually-hidden">Page</span> </a> </li> <For each={api().pages}> {(page, i) => { if (page.type === "page") return ( <li> <a href={`#${page.value}`} {...api().getItemProps(page)}> {page.value} </a> </li> ) return ( <li> <span {...api().getEllipsisProps({ index: i() })}> … </span> </li> ) }} </For> <li> <a href="#next" {...api().nextTriggerProps}> Next <span class="visually-hidden">Page</span> </a> </li> </ul> </nav> )} </div> ) }
const api = connect(state, send) // You can slice the data, to get data for current page const currentPageData = data.slice(api.pageRange.start, api.pageRange.end) api.page // => 1 api.isFirstPage() // => true api.setPage(3) // page => 3 api.previousPage // => 2 api.nextPage // => 4 api.pages /* [ { "type": "page", "value": 1, }, { "type": "page", "value": 2, }, { "type": "ellipsis", }, { "type": "page", "value": 3, }, { "type": "page", "value": 4, }, ] */ api.pageRange // => { start: 4, end: 13 }
Styling guide
Earlier, we mentioned that each pagination part has a data-part attribute
added to them to select and style them in the DOM.
[data-part="root"] { /* styles for the pagination's root */ } [data-part="item"] { /* styles for the pagination's items */ } [data-part="ellipsis"] { /* styles for the pagination's ellipsis */ } [data-part="prev-trigger"] { /* styles for the pagination's previous page trigger */ } [data-part="next-trigger"] { /* styles for the pagination's next page trigger */ } /* We add a data-disabled attribute to the prev/next items when on the first/last page */ [data-part="prev-trigger"][data-disabled] { /* styles for the pagination's previous page trigger when on first page */ } [data-part="next-trigger"][data-disabled] { /* styles for the pagination's next page trigger when on first page */ }
Methods and Properties
Machine Context
The pagination machine exposes the following context properties:
idsPartial<{ root: string; ellipsis(index: number): string; prevTrigger: string; nextTrigger: string; item(page: number): string; }>The ids of the elements in the accordion. Useful for composition.translationsIntlTranslationsSpecifies the localized strings that identifies the accessibility elements and their statescountnumberTotal number of data itemspageSizenumberNumber of data items per pagesiblingCountnumberNumber of pages to show beside active pagepagenumberThe active pageonPageChange(details: PageChangeDetails) => voidCalled when the page number is changed, and it takes the resulting page number argumenttype"button" | "link"The type of the trigger elementdir"ltr" | "rtl"The document's text/writing direction.idstringThe unique identifier of the machine.getRootNode() => ShadowRoot | Node | DocumentA root node to correctly resolve document in custom environments. E.x.: Iframes, Electron.
Machine API
