Demo on CodeSandbox.

Installation

``bash
npm install @algolia/react-instantsearch-widget-loadmore-with-progressbar


or


yarn add @algolia/react-instantsearch-widget-loadmore-with-progressbar
`

Usage

`tsx
import React from 'react';
import ReactDOM from 'react-dom';
import { InstantSearch, SearchBox, Hits, Panel } from 'react-instantsearch-dom';
import algoliasearch from 'algoliasearch/lite';
import { LoadMoreWithProgressBar } from '@algolia/react-instantsearch-widget-loadmore-with-progressbar';
import type { TextTranslationArgs } from '@algolia/react-instantsearch-widget-loadmore-with-progressbar';

// Import default styles
import '@algolia/react-instantsearch-widget-loadmore-with-progressbar/dist/style.css';

const searchClient = algoliasearch('appId', 'apiKey');

ReactDOM.render(



translations={{
loadMore: 'Load more',
searchStalled: 'Loading...',
text: ({ nbSeenHits, nbTotalHits }: TextTranslationArgs) =>
You've seen ${nbSeenHits} item${
nbSeenHits > 1 ? 's' : ''
} out of ${nbTotalHits},
}}
/>
,
document.getElementById('root')
);
`

Styling

The widget ships with default styles that you can import either from the NPM package or directly from a CDN like JSDelivr.

`js
import '@algolia/react-instantsearch-widget-loadmore-with-progressbar/dist/style.css';
`

`html
rel="stylesheet"
href="https://cdn.jsdelivr.net/npm/@algolia/react-instantsearch-widget-loadmore-with-progressbar/dist/style.css"
/>
`

Note: This widget has its own load more button. If you use the InfiniteHits widget, a second load more button will show. You can hide it using this CSS rule:

`css
/ Hide InfiniteHits widget load more button but not LoadMoreWithProgressBar widget load more button /
.ais-InfiniteHits-loadMore:not(.ais-LoadMoreWithProgressBar-loadMore) {
display: none;
}
`

$3

The widget styles uses CSS variables that you can customize in your own CSS.
You can override CSS variables using the .ais-LoadMoreWithProgressBar class.

| Name | Type | Description |
| --- | --- | --- |
| --bar-color | [color][css-color] | Progress bar background color. |
| --value-color | [color][css-color] | Progress value background color. |

Requirements

You will have to use the InfiniteHits widget to display the hits.
This widget only displays a load more button and a progress bar.
