@rspress/plugin-algolia
Source Code

Based on docsearch, this plugin replaces Rspress's built-in search with algolia.

Installation

npm

yarn

pnpm

bun

deno

npm add @rspress/plugin-algolia -D

Usage

First, add the following configuration to rspress.config.ts:

// rspress.config.ts
import path from 'path';
import { defineConfig } from '@rspress/core';
import { pluginAlgolia } from '@rspress/plugin-algolia';

export default defineConfig({
  plugins: [pluginAlgolia()],
});

Then override the Search component with an algolia-supported search box via Custom Theme.

// theme/index.tsx
import { Search as PluginAlgoliaSearch } from '@rspress/plugin-algolia/runtime';

const Search = () => {
  return (
    <PluginAlgoliaSearch
      docSearchProps={{
        appId: 'R2IYF7ETH7', // Replace with your own Algolia appId
        apiKey: '599cec31baffa4868cae4e79f180729b', // Replace with your own Algolia apiKey
        indexName: 'docsearch', // Replace with your own Algolia indexName
      }}
    />
  );
};
export { Search };
export * from '@rspress/core/theme';

Configuration

The plugin accepts an options object with the following type:

interface Options {
  verificationContent?: string;
}

verificationContent

Type: string | undefined
Default: undefined

Used for meta tag verification when creating algolia crawler. Format: <meta name="algolia-site-verification" content="YOUR_VERIFICATION_CONTENT" />. Refer to Create a new crawler - algolia

SearchProps

The SearchProps type from @rspress/plugin-algolia/runtime is as follows:

import type { DocSearchProps } from '@docsearch/react';

type Locales = Record<
  string,
  { translations: DocSearchProps['translations']; placeholder: string }
>;
type SearchProps = {
  /**
   * @link https://docsearch.algolia.com/docs/api
   */
  docSearchProps?: DocSearchProps;
  locales?: Locales;
};

docSearchProps

Type: import('@docsearch/react').DocSearchProps
Default: undefined

docSearchProps will be directly passed to the <DocSearch /> component in @docsearch/react. For specific types, please refer to docsearch documentation.

locales

Type:

type Locales = Record<
  string,
  { translations: DocSearchProps['translations']; placeholder: string }
>;

Default: {}

For customizing translated text in different languages, Rspress provides the following translated text, which can be imported through import.

import type { DocSearchProps } from '@docsearch/react';

export type Locales = Record<
  string,
  { translations: DocSearchProps['translations']; placeholder: string }
>;

// cspell:disable
export const ZH_LOCALES: Locales = {
  zh: {
    placeholder: '搜索文档',
    translations: {
      button: {
        buttonText: '搜索',
        buttonAriaLabel: '搜索',
      },
      modal: {

          suggestedQueryText: '你可以尝试查询',
          reportMissingResultsText: '你认为该查询应该有结果？',
          reportMissingResultsLinkText: '点击反馈',
        },
      },
    },
  },
} as const;

export const RU_LOCALES: Locales = {

    translations: {
      button: {
        buttonText: 'Поиск',

          reportMissingResultsLinkText: 'Сообщите об этом',
        },
      },
    },
  },
} as const;
// cspell:enable

Rspress provides Chinese translation by default, and you can customize translated text in different languages through locales.

Example:

import { Search as PluginAlgoliaSearch, ZH_LOCALES } from '@rspress/plugin-algolia/runtime';

<PluginAlgoliaSearch locales={ZH_LOCALES} />
// or
<PluginAlgoliaSearch
  locales={{
    en: {
      placeholder: 'Search Documentation',
      translations: {
        button: {
          buttonText: 'Search',
          buttonAriaLabel: 'Search',
        }
      }
    },
    ...ZH_LOCALES,
  }}
/>

Algolia crawler config

Here is an example config based on what this site uses:

new Crawler({
  appId: 'YOUR_APP_ID',
  apiKey: 'YOUR_API_KEY',
  rateLimit: 8,
  maxDepth: 10,
  startUrls: ['https://rspress.rs'],
  sitemaps: ['https://rspress.rs/sitemap.xml'],
  discoveryPatterns: ['https://rspress.rs/**'],
  actions: [
    {
      indexName: 'doc_search_rspress_pages',
      pathsToMatch: ['https://rspress.rs/**'],
      recordExtractor: ({ $, helpers }) => {
        const lvl0 =
          $('.rspress-nav-menu-item.rspress-nav-menu-item-active')
            .first()
            .text() || 'Documentation';

        return helpers.docsearch({
          recordProps: {
            lvl0: {
              selectors: '',
              defaultValue: lvl0,
            },

        'unordered(hierarchy.lvl4)',
        'unordered(hierarchy.lvl5)',
        'unordered(hierarchy.lvl6)',

      removeWordsIfNoResults: 'allOptional',
    },
  },
});

Distinguish search results based on i18n

You can achieve internationalized search results by combining Runtime API with docSearchProps.

Here's an example using docSearchProps.searchParameters:

// theme/index.tsx
import { useLang } from '@rspress/core/runtime';
import { Search as PluginAlgoliaSearch } from '@rspress/plugin-algolia/runtime';

const Search = () => {
  const lang = useLang();
  return (
    <PluginAlgoliaSearch
      docSearchProps={{
        appId: 'R2IYF7ETH7',
        apiKey: '599cec31baffa4868cae4e79f180729b',
        indexName: 'docsearch',
        searchParameters: {
          facetFilters: [`lang:${lang}`],
        },
      }}
    />
  );
};
export { Search };
export * from '@rspress/core/theme';
