# Azure blob storage file 集成

> 使用 LangChain JavaScript 集成 Azure blob storage file document loader。

<Tip>
  **兼容性**

  Only available on Node.js.
</Tip>

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

## 设置

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

## 用法

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={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
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);
```
