@thinkbucket/docusaurus-search-local

An offline/local search plugin for Docusaurus v2, which supports multiple languages, especially optimized for language of zh.

Originally forked from cmfcmf/docusaurus-search-local.

Then later fully rewritten with TypeScript 💪, styles polished 💅, language of Chinese supported 🇨🇳, and tests covered ✅.

Installation

npm install --save @thinkbucket/docusaurus-search-local
# or
yarn add @thinkbucket/docusaurus-search-local

Usage

Add @thinkbucket/docusaurus-search-local into your docusaurus plugins.

// In your `docusaurus.config.js`:
module.exports = {
  // ... Your other configurations.
  plugins: [
    // ... Your other plugins.
    [
      require.resolve("@thinkbucket/docusaurus-search-local"),
      {
        // ... Your options.
        // `hashed` is recommended as long-term-cache of index file is possible.
        hashed: true,
        // For Docs using Chinese, The `language` is recommended to set to:
        // ```
        // language: ["en", "zh"],
        // ```
        // When applying `zh` in language, please install `nodejieba` in your project.
      },
    ],
  ],
};

Notice!

When applying "zh" in language, please also install nodejieba in your project, which is required for tokenizing Chinese words. It is removed from peerDependencies since v0.20.0, so you have to install it manually even if you're using npm v7+.

npm install nodejieba
# or
yarn add nodejieba

Trouble Shooting

When building your docs project, Set the env DEBUG=search-local:* to enable debug logs.

# In your docs project:
DEBUG=search-local:* yarn build

In case some specific errors occurred:

Error: Cannot mix different versions of joi schemas:
- Try using @thinkbucket/docusaurus-search-local >= v0.16.0 with Docusaurus >= v2.0.0-alpha.73
- Try using @thinkbucket/docusaurus-search-local between v0.14.0 and v0.15.1 with Docusaurus between v2.0.0-alpha.68 and v2.0.0-alpha.72
- Or try using @thinkbucket/docusaurus-search-local <= v0.13.1 with Docusaurus <= v2.0.0-alpha.66
Error: Command failed with signal "SIGSEGV":
- This is probably caused by a known issue introduced by nodejieba@2.5.2, if you enabled language of zh.
- Try downgrading nodejieba to 2.4.2 and it will work again, see discussions in #47.
