# Azure blob storage file integration

> Integrate with the Azure blob storage file document loader using LangChain JavaScript.

<Tip>
  **Compatibility**

  Only available on Node.js.
</Tip>

This covers how to load an Azure File into LangChain documents.

## Setup

To use this loader, you'll need to have Unstructured already set up and ready to use at an available URL endpoint. It can also be configured to run locally.

See the [Unstructured file loaders documentation](/oss/javascript/integrations/document_loaders/file_loaders/unstructured) for information on how to do that.

You'll also need to install the official Azure Storage Blob client library:

```bash npm theme={null}
npm install @langchain/community @langchain/core @azure/storage-blob
```

## Usage

Once Unstructured is configured, you can use the Azure Blob Storage File loader to load files and then convert them into a Document.

```typescript theme={null}
import { AzureBlobStorageFileLoader } from "@langchain/community/document_loaders/web/azure_blob_storage_file";

const loader = new AzureBlobStorageFileLoader({
  azureConfig: {
    connectionString: "",
    container: "container_name",
    blobName: "example.txt",
  },
  unstructuredConfig: {
    apiUrl: "http://localhost:8000/general/v0/general",
    apiKey: "", // this will be soon required
  },
});

const docs = await loader.load();

console.log(docs);
```
