Pagination

Pagination is an interface that allows navigating between pages that contain split information, instead of being shown on a single page.

Installation

To use the pagination machine in your project, run the following command in your command line:

npm install @zag-js/pagination @zag-js/vue
# or
yarn add @zag-js/pagination @zag-js/vue

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-part attribute 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 id to the useMachine hook. This is used to ensure that every part has a unique identifier.

<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 service = useMachine(pagination.machine, {
    id: "1",
    count: data.length,
  })

  const api = computed(() => pagination.connect(service, normalizeProps))
</script>

<template>
  <nav v-if="api.totalPages > 1" v-bind="api.getRootProps()">
    <ul>
      <li>
        <a href="#previous" v-bind="api.getPrevTriggerProps()">
          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 })">&#8230;</span>
        </span>
      </li>
      <li>
        <a href="#next" v-bind="api.getNextTriggerProps()">
          Next <span class="visually-hidden">Page</span>
        </a>
      </li>
    </ul>
  </nav>
</template>

const api = connect(service)

// 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.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 states
  • countnumberTotal number of data items
  • pageSizenumberThe controlled number of data items per page
  • defaultPageSizenumberThe initial number of data items per page when rendered. Use when you don't need to control the page size of the pagination.
  • siblingCountnumberNumber of pages to show beside active page
  • pagenumberThe controlled active page
  • defaultPagenumberThe initial active page when rendered. Use when you don't need to control the active page of the pagination.
  • onPageChange(details: PageChangeDetails) => voidCalled when the page number is changed
  • onPageSizeChange(details: PageSizeChangeDetails) => voidCalled when the page size is changed
  • type"button" | "link"The type of the trigger element
  • dir"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

The pagination api exposes the following methods:

  • pagenumberThe current page.
  • countnumberThe total number of data items.
  • pageSizenumberThe number of data items per page.
  • totalPagesnumberThe total number of pages.
  • pagesPagesThe page range. Represented as an array of page numbers (including ellipsis)
  • previousPagenumberThe previous page.
  • nextPagenumberThe next page.
  • pageRangePageRangeThe page range. Represented as an object with `start` and `end` properties.
  • slice<V>(data: V[]) => V[]Function to slice an array of data based on the current page.
  • setPageSize(size: number) => voidFunction to set the page size.
  • setPage(page: number) => voidFunction to set the current page.
  • goToNextPageVoidFunctionFunction to go to the next page.
  • goToPrevPageVoidFunctionFunction to go to the previous page.
  • goToFirstPageVoidFunctionFunction to go to the first page.
  • goToLastPageVoidFunctionFunction to go to the last page.
