'How to implement pagination in React

I am new to ReactJS and am creating a simple TODO application in it. Actually, it is a very basic app with no DB connection, tasks are stored in an array. I added Edit and Delete functionality to it now I want to add pagination.

How do I implement it? Any help will be appreciated. Thank you...!!



Solution 1:[1]

I've implemented pagination in pure React JS recently. Here is a working demo: http://codepen.io/PiotrBerebecki/pen/pEYPbY

You would of course have to adjust the logic and the way page numbers are displayed so that it meets your requirements.

Full code:

class TodoApp extends React.Component {
  constructor() {
    super();
    this.state = {
      todos: ['a','b','c','d','e','f','g','h','i','j','k'],
      currentPage: 1,
      todosPerPage: 3
    };
    this.handleClick = this.handleClick.bind(this);
  }

  handleClick(event) {
    this.setState({
      currentPage: Number(event.target.id)
    });
  }

  render() {
    const { todos, currentPage, todosPerPage } = this.state;

    // Logic for displaying todos
    const indexOfLastTodo = currentPage * todosPerPage;
    const indexOfFirstTodo = indexOfLastTodo - todosPerPage;
    const currentTodos = todos.slice(indexOfFirstTodo, indexOfLastTodo);

    const renderTodos = currentTodos.map((todo, index) => {
      return <li key={index}>{todo}</li>;
    });

    // Logic for displaying page numbers
    const pageNumbers = [];
    for (let i = 1; i <= Math.ceil(todos.length / todosPerPage); i++) {
      pageNumbers.push(i);
    }

    const renderPageNumbers = pageNumbers.map(number => {
      return (
        <li
          key={number}
          id={number}
          onClick={this.handleClick}
        >
          {number}
        </li>
      );
    });

    return (
      <div>
        <ul>
          {renderTodos}
        </ul>
        <ul id="page-numbers">
          {renderPageNumbers}
        </ul>
      </div>
    );
  }
}


ReactDOM.render(
  <TodoApp />,
  document.getElementById('app')
);

I have tried to recreate the simple pagination example given by piotr-berebecki which was great. But when there will be a lot of pages then the pagination will overflow in the screen. So, I used previous and back button along with forward and backward button to stream back and forth between the pages. And for design part I have used bootstrap 3.

You can customize no of pages to display in pagination using the pagebound values. Make sure to use same value for upperPageBound and pageBound.

    class TodoApp extends React.Component {
          constructor() {
            super();
            this.state = {
              todos: ['a','b','c','d','e','f','g','h','i','j','k','l','m',
'n','o','p','q','r','s','t','u','v','w','x','y','z'],
              currentPage: 1,
              todosPerPage: 3,
              upperPageBound: 3,
              lowerPageBound: 0,
              isPrevBtnActive: 'disabled',
              isNextBtnActive: '',
              pageBound: 3
            };
            this.handleClick = this.handleClick.bind(this);
            this.btnDecrementClick = this.btnDecrementClick.bind(this);
            this.btnIncrementClick = this.btnIncrementClick.bind(this);
            this.btnNextClick = this.btnNextClick.bind(this);
            this.btnPrevClick = this.btnPrevClick.bind(this);
            // this.componentDidMount = this.componentDidMount.bind(this);
            this.setPrevAndNextBtnClass = this.setPrevAndNextBtnClass.bind(this);
          }
          componentDidUpdate() {
                $("ul li.active").removeClass('active');
                $('ul li#'+this.state.currentPage).addClass('active');
          }
          handleClick(event) {
            let listid = Number(event.target.id);
            this.setState({
              currentPage: listid
            });

Solution 3:[3]

Here is a way to create your Custom Pagination Component from react-bootstrap lib and this component you can use Throughout your project enter image description here

Your Pagination Component (pagination.jsx or js)

import React, { Component } from "react"; 
import { Pagination } from "react-bootstrap"; 
import PropTypes from "prop-types";

export default class PaginationHandler extends Component {  

   constructor(props) {
    super(props);
    this.state = {
      paging: {
        offset: 0,
        limit: 10
      },
      active: 0
    };  
    }

  pagingHandler = () => {
    let offset = parseInt(event.target.id);
    this.setState({
      active: offset
    });
    this.props.pageHandler(event.target.id - 1);   };

  nextHandler = () => {
    let active = this.state.active;
    this.setState({
      active: active + 1
    });
    this.props.pageHandler(active + 1);   };

  backHandler = () => {
    let active = this.state.active;
    this.setState({
      active: active - 1
    });
    this.props.pageHandler(active - 1);   };

  renderPageNumbers = (pageNumbers, totalPages) => {
    let { active } = this.state;
    return (
      <Pagination>
        <Pagination.Prev disabled={active < 5} onClick={ active >5 && this.backHandler} />

        {
      pageNumbers.map(number => {
              if (
                number >= parseInt(active) - 3 &&
                number <= parseInt(active) + 3 
              ) {
                return (
                  <Pagination.Item
                    id={number}
                    active={number == active}
                    onClick={this.pagingHandler}
                  >
                    {number}
                  </Pagination.Item>
                );
              } else {
                return null;
              }
        })}
        <Pagination.Next onClick={ active <= totalPages -4 && this.nextHandler} />
      </Pagination>
    );   };

  buildComponent = (props, state) => {
    const { totalPages } = props;
    const pageNumbers = [];
    for (let i = 1; i <= totalPages; i++) {
      pageNumbers.push(i);
    }
    return (
      <div className="pull-right">
      {this.renderPageNumbers(pageNumbers ,totalPages)}
      </div>
    );   
};

  render() {
    return this.buildComponent(this.props, this.state);
  } 

} 
   PaginationHandler.propTypes = 
   {
    paging: PropTypes.object,
    pageHandler: PropTypes.func,
    totalPages: PropTypes.object 
   };

Use of Above Child Component in your Parent Component as shown below

import Pagination from "../pagination";

pageHandler = (offset) =>{
      this.setState(({ paging }) => ({
        paging: { ...paging, offset: offset }
      }));
   }
   render() {
    return (
      <div>
         <Pagination
          paging = {paging}
          pageHandler = {this.pageHandler}
          totalPages = {totalPages}>
          </Pagination>
      </div>
    );
  }

I recently created this Pagination component that implements paging logic like Google's search results:

import React, { PropTypes } from 'react';
 
const propTypes = {
    items: PropTypes.array.isRequired,
    onChangePage: PropTypes.func.isRequired,
    initialPage: PropTypes.number   
}
 
const defaultProps = {
    initialPage: 1
}
 
class Pagination extends React.Component {
    constructor(props) {
        super(props);
        this.state = { pager: {} };
    }
 
    componentWillMount() {
        this.setPage(this.props.initialPage);
    }
 
    setPage(page) {
        var items = this.props.items;
        var pager = this.state.pager;
 
        if (page < 1 || page > pager.totalPages) {

Pagination.propTypes = propTypes;
Pagination.defaultProps
export default Pagination;

And here's an example App component that uses the Pagination component to paginate a list of 150 example items:

import React from 'react';
import Pagination from './Pagination';
 
class App extends React.Component {
    constructor() {
        super();
 
        // an example array of items to be paged
        var exampleItems = _.range(1, 151).map(i => { return { id: i, name: 'Item ' + i }; });
 
        this.state = {
            exampleItems: exampleItems,
            pageOfItems: []
        };
 
        // bind function in constructor instead of render (https://github.com/yannickcr/eslint-plugin-react/blob/master/docs/rules/jsx-no-bind.md)
        this.onChangePage = this.onChangePage.bind(this);
    }
 
    onChangePage(pageOfItems) {
        // update state with new page of items
        this.setState({ pageOfItems: pageOfItems });
    }
 
    render() {
        return (
            <div>
                <div className="container">
                    <div className="text-center">
                        <h1>React - Pagination Example with logic like Google</h1>
                        {this.state.pageOfItems.map(item =>
                            <div key={item.id}>{item.name}</div>
                        )}
                        <Pagination items={this.state.exampleItems} onChangePage={this.onChangePage} />
                    </div>
                </div>
                <hr />

Please see this code sample in codesandbox

https://codesandbox.io/s/pagino-13pit

enter image description here

import Pagino from "pagino";
import { useState, useMemo } from "react";

export default function App() {
  const [pages, setPages] = useState([]);

  const pagino = useMemo(() => {
    const _ = new Pagino({
      showFirst: false,
      showLast: false,
      onChange: (page, count) => setPages(_.getPages())
    });

    _.setCount(10);

    return _;
  }, []);

  const hanglePaginoNavigation = (type) => {
    if (typeof type === "string") {
      pagino[type]?.();
      return;
    }

    pagino.setPage(type);
  };

  return (
    <div>

    </div>
  );
}

I've recently created library which helps to cope with pagination cases like:

  • storing normalized data in Redux
  • caching pages based on search filters
  • simplified react-virtualized list usage
  • refreshing results in background
  • storing last visited page and used filters

DEMO page implements all above features.

Source code you can find on Github

A ReactJS dumb component to render pagination. You can also use this Library:

https://www.npmjs.com/package/react-js-pagination

Some Examples are Here:

OR

You can also Use this https://codepen.io/PiotrBerebecki/pen/pEYPbY

Make sure you make it as a separate component I have used tabler-react

import * as React from "react";
import { Page,  Button } from "tabler-react";
class PaginateComponent extends React.Component {
    constructor(props) {
        super(props);
        this.state = {
            array: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
            limit: 5, // optional
            page: 1
        };
    }

paginateValue = (page) => {
    this.setState({ page: page });
    console.log(page) // access this value from parent component 
}

paginatePrevValue = (page) => {
    this.setState({ page: page });
    console.log(page)  // access this value from parent component
}
paginateNxtValue = (page) => {
       this.setState({ page: page });
       console.log(page)  // access this value from parent component
    }

    render() {
        return (
            <div>    
                <div>
                    <Button.List>
                        <Button
                      disabled={this.state.page === 0}
                      onClick={() => this.paginatePrevValue(this.state.page - 1)}
                            outline
                            color="primary"

                            Previous
                      </Button>

                        {this.state.array.map((value, index) => {
                            return (
                                <Button
                                    onClick={() => this.paginateValue(value)}
                                    color={
                                        this.state.page === value
                                            ? "primary"
                                            : "secondary"

                            );
                        })}

                            color="secondary"
                        >
                            Next
                      </Button>
                    </Button.List>

I have implemented pagination + search in ReactJs, see the output: Pagination in React

View complete code on GitHub: https://github.com/navanathjadhav/generic-pagination

Also visit this article for step by step implementation of pagination: https://everblogs.com/react/3-simple-steps-to-add-pagination-in-react/

Solution 11:[11]

1- Use react-bootstrap

import React from "react";
import { Pagination } from "react-bootstrap";
import Link from "next/link";

interface PaginateProps {
  pages: number;
  page: number;
  keyword?: string;
  isAdmin?: boolean;
}

const Paginate = ({
  pages,
  page,
  // keyword is for searching
  keyword = "",
  isAdmin = false,
}: PaginateProps) => {
  return pages > 1 ? (
    <Pagination>
      {/* keys returns a new Array iterator contians the keys for each index */} 
      // pages is total number of pages
      {[...Array(pages).keys()].map((x) => (
        // this is next.js component. you could use react Link
        <Link
          passHref
          key={x + 1}
          href={
            !isAdmin
              // since array indexing starts at 0, use x+1
              ? `/?keyword=${keyword}&page=${x + 1}`
              : `/admin/productlist/?keyword=${keyword}&page=${x + 1}`
          }
        >
          <Pagination.Item active={x + 1 === page}>{x + 1}</Pagination.Item>
        </Link>
      ))}
    </Pagination>
  ) : null;
};

export default Paginate;

then use it in a page.

    <Paginate page={page} pages={pages} keyword={keyword} />

2- use react-js pagination

  import Pagination from "react-js-pagination";

  // bootstrap class to center 
  <div className="d-flex justify-content-center mt-5">
      <Pagination
        activePage={page}
        itemsCountPerPage={resPerPageValue}
        totalItemsCount={Count}
        onChange={handlePagination}
        nextPageText={"Next"}
        prevPageText={"Prev"}
        firstPageText={"First"}
        lastPageText={"Last"}
        // overwriting the style
        itemClass="page-item"
        linkClass="page-link"
      />
    </div>

onChange handler

 const handlePagination = (pageNumber) => {
    // window.location.href will reload entire page
    router.push(`/?page=${pageNumber}`);
  };
