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. 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.

defaultAdditional

Not required. Default additional for empty search if options or defaultOptions defined.

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.

reloadOnErrorTimeout

Not required. Number. Time in milliseconds to retry a request after an error

cacheUniqs

Not required. Array. Works as 2nd argument of useEffect hook. When one of items changed, AsyncPaginate cleans all cached options.

loadOptionsOnMenuOpen

Not required. Boolean. If false options will not load on menu opening.

selectRef

Ref for take react-select instance.

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 react-select component

You can use withAsyncPaginate HOC.

import { withAsyncPaginate } from 'react-select-async-paginate';

...

const CustomAsyncPaginate = withAsyncPaginate(CustomSelect);

typescript

Describing type of component with extra props (example with Creatable):

import type { ReactElement } from 'react';
import type { GroupBase } from 'react-select';
import Creatable from 'react-select/creatable';
import type { CreatableProps } from 'react-select/creatable';

import { withAsyncPaginate } from 'react-select-async-paginate';
import type {
  UseAsyncPaginateParams,
  ComponentProps,
} from 'react-select-async-paginate';

type AsyncPaginateCreatableProps<
OptionType,
Group extends GroupBase<OptionType>,
Additional,
IsMulti extends boolean,
> =
  & CreatableProps<OptionType, IsMulti, Group>
  & UseAsyncPaginateParams<OptionType, Group, Additional>
  & ComponentProps<OptionType, Group, IsMulti>;

type AsyncPaginateCreatableType = <
OptionType,
Group extends GroupBase<OptionType>,
Additional,
IsMulti extends boolean = false,
>(props: AsyncPaginateCreatableProps<OptionType, Group, Additional, IsMulti>) => ReactElement;

const AsyncPaginateCreatable = withAsyncPaginate(Creatable) as AsyncPaginateCreatableType;

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,
  }}
/>

Extended usage

If you want construct own component that uses logic of react-select-async-paginate inside, you can use next hooks:

• useAsyncPaginate
• useAsyncPaginateBase
• useComponents

import {
  useAsyncPaginate,
  useComponents,
} from 'react-select-async-paginate';

...

const CustomAsyncPaginateComponent = ({
  options,
  defaultOptions,
  additional,
  loadOptionsOnMenuOpen,
  debounceTimeout,
  filterOption,
  reduceOptions,
  shouldLoadMore,

  components: defaultComponents,

  value,
  onChange,
}) => {
  const asyncPaginateProps = useAsyncPaginate({
    options,
    defaultOptions,
    additional,
    loadOptionsOnMenuOpen,
    debounceTimeout,
    filterOption,
    reduceOptions,
    shouldLoadMore,
  });

  const components = useComponents(defaultComponents);

  return (
    <CustomSelect
      {...asyncPaginateProps}
      components={components}
      value={value}
      onChange={onChange}
    />
  );
}

useComponents provides redefined MenuList component by default. If you want redefine it, you should also wrap in with wrapMenuList.
