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

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 (
      
        5 && this.backHandler} />

        {
      pageNumbers.map(number => {
              if (
                number >= parseInt(active) - 3 &&
                number <= parseInt(active) + 3 
              ) {
                return (
                  
                    {number}
                  
                );
              } else {
                return null;
              }
        })}
        
      
    );   };

  buildComponent = (props, state) => {
    const { totalPages } = props;
    const pageNumbers = [];
    for (let i = 1; i <= totalPages; i++) {
      pageNumbers.push(i);
    }
    return (
      

      {this.renderPageNumbers(pageNumbers ,totalPages)}
      
    );   
};

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

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

Use of Above Component in your Component

import Pagination from "../pagination";

pageHandler = (offset) =>{
      this.setState(({ paging }) => ({
        paging: { ...paging, offset: offset }
      }));
   }
   render() {
    return (
      

         
          
      
    );
  }
