Azure Blob Storage File
=======================

Compatibility

Only available on Node.js.

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

Setup[​](#setup "Direct link to 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 docs [here](/v0.2/docs/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:

*   npm
*   Yarn
*   pnpm

    npm install @azure/storage-blob

    yarn add @azure/storage-blob

    pnpm add @azure/storage-blob

Usage[​](#usage "Direct link to Usage")
---------------------------------------

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

    import { AzureBlobStorageFileLoader } from "langchain/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);
