# EPUB 文件 - 集成

> 使用 LangChain JavaScript 与 EPUB 文件文档加载器进行集成。

本示例介绍了如何从 EPUB 文件中加载数据。默认情况下，EPUB 文件中的每个章节将创建一个文档，您可以通过将 `splitChapters` 选项设置为 `false` 来更改此行为。

# 安装

```bash npm theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
npm install @langchain/community @langchain/core epub2 html-to-text
```

# 使用方式，每个章节一个文档

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import { EPubLoader } from "@langchain/community/document_loaders/fs/epub";

const loader = new EPubLoader("src/document_loaders/example_data/example.epub");

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

# 使用方式，每个文件一个文档

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import { EPubLoader } from "@langchain/community/document_loaders/fs/epub";

const loader = new EPubLoader(
  "src/document_loaders/example_data/example.epub",
  {
    splitChapters: false,
  }
);

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