Demo

Installation

Usage

import React from 'react';
import ReactScrollablePagination from 'react-scrollable-pagination';
import {withrouter} from 'react-router-dom';

// inject history and location props
const Scroller = withRouter(ReactScrollablePagination);

const Component = () => (
  <div>
    <h3>Example</h3>
    <Scroller
      className="scroller"
      style={{height: '70vh', border: '1px solid black'}}
      pageParam="page"
      fixed
      fetchData={page => {
        return fetch(`${URL}?page=${page}`);
      }}
      dataSelector={res => res}
      metaSelector={res => res.meta || {totalPages: 10}}
      loader={<div className="loader" />}
      beforeInitialLoad={() => console.log('Init')}
      afterInitialLoad={() => console.log('Done')}
    >
      /* IF USING FIXED: you will probably need to give minHeight of the div to
      be at least the same as the height of the component itself, to maintain
      scrollability even when there is not enough items to overflow. But if you
      have only one page, setting won't be neccessary, and will only add
      unneccessary scrollbar, so make sure you have more than one page before
      giving it the minHeight property */
      {(data, meta) => (
        <div style={meta.totalPages > 1 ? {minHeight: '70vh'} : {}}>
          data.map(item => (
          <div key={item}>
            <Link to={`/item/${item}`}>{item}</Link>
          </div>
          ))
        </div>
      )}
    </Scroller>
  </div>
);

fetchData	function	true		Function that will fetch the data. It accepts 'page' parameter and It's return value must be a promise.

style	object	false	{}	Custom inline styles for the component.
pageParam	string	false	"page"	The query parameter that will control pagination.
fixed	boolean	false	false	Should be set if the component should become scrollable. In that case it must have fixed height. If false, window scroll will control pagination.
loader	JSX element	false	</div>Loading...</div>	Custom loader to display on top or bottom of the component while loading more data.
beforeInitialLoad	function	false	noop func	Function that is triggered when the component is mounted and before fetching the data. Convenient to display loading spinner until the initial data is loaded.
afterInitialLoad	function	false	noop func	Function that is triggered when the result of fetchData is resolved. Convenient to hide loading spinner once the data has been loaded.

Todo

• Make it independent of react-router (At the moment, the user must wrap it inside withRouter to be able to use it properly )
• Add option to add top and bottom offset. (At the moment, it scrolls up and down when scroller reaches top and bottom.)
