# 文档加载器集成

> 使用 LangChain JavaScript 与文档加载器集成。

文档加载器提供了一个**标准接口**，用于从不同来源（如 Slack、Notion 或 Google Drive）读取数据，并将其转换为 LangChain 的 [Document](https://reference.langchain.com/javascript/langchain-core/documents/Document) 格式。
这确保了无论数据来源如何，都能以一致的方式进行处理。

所有文档加载器都实现了 [BaseLoader](https://reference.langchain.com/javascript/classes/_langchain_core.document_loaders_base.BaseDocumentLoader.html) 接口。

## 接口

每个文档加载器可以定义自己的参数，但它们共享一个通用的 API：

* `load()`: 一次性加载所有文档。
* `loadAndSplit()`: 一次性加载所有文档，并将其拆分为更小的文档。

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

const loader = new CSVLoader(
  ...  // <-- 此处为集成特定参数
);
const data = await loader.load();
```

## 按类别划分

LangChain.js 以两种不同的方式对文档加载器进行分类：

* [文件加载器](/oss/javascript/integrations/document_loaders/file_loaders/)，用于从本地文件系统将数据加载到 LangChain 格式。
* [网络加载器](/oss/javascript/integrations/document_loaders/web_loaders/)，用于从远程源加载数据。
