Versions

Installation

npm install react-select react-select-async-paginate

or

yarn add react-select react-select-async-paginate

Usage

AsyncPaginate is an alternative of Async but supports loading page by page. It is wrapper above default react-select thus it accepts all props of default Select except isLoading. And there are some new props:

loadOptions

Required. Async function that take next arguments:

1. Current value of search input.
2. Loaded options for current search.
3. Collected additional data e.g. current page number etc. For first load it is additional from props, for next is additional from previous response for current search. null by default.

It should return next object:

{
  options: Array,
  hasMore: boolean,
  additional?: any,
}

It similar to loadOptions from Select.Async but there is some differences:

1. Loaded options as 2nd argument.
2. Additional data as 3nd argument.
3. Not supports callback.
4. Should return hasMore for detect end of options list for current search.

debounceTimeout

Not required. Number. Debounce timeout for loadOptions calls. 0 by default.

additional

Not required. Default additional for first request for every search.

shouldLoadMore

Not required. Function. By default new options will load only after scroll menu to bottom. Arguments:

• scrollHeight
• clientHeight
• scrollTop

Should return boolean.

reduceOptions

Not required. Function. By default new loaded options are concat with previous. Arguments:

• previous options
• loaded options
• next additional

Should return new options.

cacheUniq

Not required. Can take any value. When this prop changed, AsyncPaginate cleans all cached options.

selectRef

Ref for take react-select instance.

SelectComponent

Not required. React component that will be used instead of SelectBase from react-select.

Example

offset way

import AsyncPaginate from 'react-select-async-paginate';

...

/*
 * assuming the API returns something like this:
 *   const json = {
 *     results: [
 *       {
 *         value: 1,
 *         label: 'Audi',
 *       },
 *       {
 *         value: 2,
 *         label: 'Mercedes',
 *       },
 *       {
 *         value: 3,
 *         label: 'BMW',
 *       },
 *     ],
 *     has_more: true,
 *   };
 */

async function loadOptions(search, loadedOptions) {
  const response = await fetch(`/awesome-api-url/?search=${search}&offset=${loadedOptions.length}`);
  const responseJSON = await response.json();

  return {
    options: responseJSON.results,
    hasMore: responseJSON.has_more,
  };
}

<AsyncPaginate
  value={value}
  loadOptions={loadOptions}
  onChange={setValue}
/>

page way

import AsyncPaginate from 'react-select-async-paginate';

...

async function loadOptions(search, loadedOptions, { page }) {
  const response = await fetch(`/awesome-api-url/?search=${search}&page=${page}`);
  const responseJSON = await response.json();

  return {
    options: responseJSON.results,
    hasMore: responseJSON.has_more,
    additional: {
      page: page + 1,
    },
  };
}

<AsyncPaginate
  value={value}
  loadOptions={loadOptions}
  onChange={setValue}
  additional={{
    page: 1,
  }}
/>

Grouped options

You can use reduceGroupedOptions util to group options by label key.

import AsyncPaginate, { reduceGroupedOptions } from 'react-select-async-paginate';

/*
 * assuming the API returns something like this:
 *   const json = {
 *     options: [
 *       label: 'Cars',
 *       options: [
 *         {
 *           value: 1,
 *           label: 'Audi',
 *         },
 *         {
 *           value: 2,
 *           label: 'Mercedes',
 *         },
 *         {
 *           value: 3,
 *           label: 'BMW',
 *         },
 *       ]
 *     ],
 *     hasMore: true,
 *   };
 */

...

<AsyncPaginate
  {...otherProps}
  reduceOptions={reduceGroupedOptions}
/>

Replacing Components

Usage of replacing components is similar with react-select, but there is one difference. If you redefine MenuList you should wrap it with wrapMenuList for workaround of some internal bugs of react-select.

import AsyncPaginate, { wrapMenuList } from 'react-select-async-paginate';

...

const MenuList = wrapMenuList(CustomMenuList);

<AsyncPaginate
  {...otherProps}
  components={{
    ...otherComponents,
    MenuList,
  }}
/>
