# DirectoryLoader

<Tip>
  **Compatibility**: Only available on Node.js.
</Tip>

This notebook provides a quick overview for getting started with `DirectoryLoader` [document loaders](/oss/javascript/integrations/document_loaders). For detailed documentation of all `DirectoryLoader` features and configurations head to the [API reference](https://api.js.langchain.com/classes/langchain.document_loaders_fs_directory.DirectoryLoader.html).

This example goes over how to load data from folders with multiple files. The second argument is a map of file extensions to loader factories. Each file will be passed to the matching loader, and the resulting documents will be concatenated together.

Example folder:

```text theme={null}
src/document_loaders/example_data/example/
├── example.json
├── example.jsonl
├── example.txt
└── example.csv
```

## Setup

To access `DirectoryLoader` document loader you'll need to install the `langchain` package.

### Installation

The LangChain DirectoryLoader integration lives in the `langchain` package:

<CodeGroup>
  ```bash npm theme={null}
  npm install langchain @langchain/core
  ```

  ```bash yarn theme={null}
  yarn add langchain @langchain/core
  ```

  ```bash pnpm theme={null}
  pnpm add langchain @langchain/core
  ```
</CodeGroup>

## Instantiation

Now we can instantiate our model object and load documents:

```typescript theme={null}
import { DirectoryLoader } from "@langchain/classic/document_loaders/fs/directory";
import {
  JSONLoader,
  JSONLinesLoader,
} from "@langchain/classic/document_loaders/fs/json";
import { TextLoader } from "@langchain/classic/document_loaders/fs/text";
import { CSVLoader } from "@langchain/community/document_loaders/fs/csv";

const loader = new DirectoryLoader(
  "../../../../../../examples/src/document_loaders/example_data",
  {
    ".json": (path) => new JSONLoader(path, "/texts"),
    ".jsonl": (path) => new JSONLinesLoader(path, "/html"),
    ".txt": (path) => new TextLoader(path),
    ".csv": (path) => new CSVLoader(path, "text"),
  }
);
```

## Load

```typescript theme={null}
const docs = await loader.load()
// disable console.warn calls
console.warn = () => {}
docs[0]
```

```output theme={null}
Document {
  pageContent: 'Foo\nBar\nBaz\n\n',
  metadata: {
    source: '/Users/bracesproul/code/lang-chain-ai/langchainjs/examples/src/document_loaders/example_data/example.txt'
  },
  id: undefined
}
```

```typescript theme={null}
console.log(docs[0].metadata)
```

```output theme={null}
{
  source: '/Users/bracesproul/code/lang-chain-ai/langchainjs/examples/src/document_loaders/example_data/example.txt'
}
```
