# Gitbook 集成

> 使用 LangChain JavaScript 集成 Gitbook 文档加载器。

本示例演示如何使用 Cheerio 从任意 GitBook 加载数据。每个页面将创建一个文档。

## 安装

```bash npm theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
npm install @langchain/community @langchain/core cheerio
```

## 从单个 GitBook 页面加载

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import { GitbookLoader } from "@langchain/community/document_loaders/web/gitbook";

const loader = new GitbookLoader(
  "https://docs.gitbook.com/product-tour/navigation"
);

const docs = await loader.load();
```

## 从指定 GitBook 的所有路径加载

要使此功能正常工作，GitbookLoader 需要使用根路径（本例中为 [https://docs.gitbook.com）进行初始化，并将](https://docs.gitbook.com）进行初始化，并将) `shouldLoadAllPaths` 设置为 `true`。

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import { GitbookLoader } from "@langchain/community/document_loaders/web/gitbook";

const loader = new GitbookLoader("https://docs.gitbook.com", {
  shouldLoadAllPaths: true,
});

const docs = await loader.load();
```
