@rpodwika/use-paginator v1.0.2

use-paginator

A simple hook to paginate any dataset in JavaScript (TypeScript)

Why

I missed a very simple hook that would make pagination from any collection in JavaScript. This library is not about styling but more about the controls that can be used with any library and adjusted to your needs. Personally, I used styled-components which I highly recommend, but you can use whatever you want

Usage

npm i @rpodwika/use-paginator or yarn add @rpodwika/use-paginator

Sample code:

import React from "react";
import { usePaginator } from '@rpodwika/use-paginator'

const data = [
  { id: 1, anything: 'a'},
  { id: 2, anything: 'b'},
  { id: 3, anything: 'c'},
  { id: 4, anything: 'd'},
  { id: 5, anything: 'e'}
]

const pageSize = 2

const Component = () => {
  const {
      currentPage, // contains current page number
      setCurrentPage, // sets a page (for example when someone clicks on a button with page number)
      pageItems, // page items to display
      totalPages, // total number of pages
      nextPage, // function to move to the next page
      prevPage  // function to move to the previous page
    } = usePaginator(data, pageSize)
  
  return (
     <>
        {pageItems.map(pi => <div id={`paged-element-${pi.id}`}>{pi.anything}</div>)}
        <div onClick={nextPage}>go to the next page</div>
        <div onClick={prevPage}>go to the previous page</div>
        <div>{currentPage}/{totalPages}</div>
        {Array.from({ length: totalPages }, (_, i) => i + 1).map((p) => (
            <div
              onClick={() => setCurrentPage(p)}
              data-is-active={p === currentPage}
              key={`page-${p}`}
            >
              {p}
            </div>
          ))}
     </>
  ) 
}

Async calls, in case "data" prop changes you'll need to use useEffect function

useEffect(() => {
    setItemList(data)
    // eslint-disable-next-line react-hooks/exhaustive-deps
  }, [data])

Eslint exhaustive deps is needed because function reference is passed. Probably, in the next major version I'll make it work with references to make it more friendly
