Depending on your use case, there are three primary ways to download files:
async function downloadBlobToBuffer(blobName) { const blobClient = containerClient.getBlobClient(blobName); // Directly download the blob into a memory buffer return await blobClient.downloadToBuffer(); } Use code with caution. For more, see the Microsoft Azure documentation .
const { BlobServiceClient } = require("@azure/storage-blob"); const AZURE_STORAGE_CONNECTION_STRING = "your_connection_string_here"; const blobServiceClient = BlobServiceClient.fromConnectionString(AZURE_STORAGE_CONNECTION_STRING); const containerClient = blobServiceClient.getContainerClient("your-container-name"); Use code with caution. download file from azure blob storage nodejs
: You will need your Connection String , which can be found in the Azure Portal under your storage account's Access keys section. Connecting to Azure Blob Storage
// Function to download blob to local file async function downloadBlobToLocal(blobName, localFilePath) { const blobClient = containerClient.getBlobClient(blobName); // Use downloadToFile to save the blob content await blobClient.downloadToFile(localFilePath); console.log(`Downloaded ${blobName} to ${localFilePath}`); } Use code with caution. Depending on your use case, there are three
Downloading files from Azure Blob Storage in a Node.js environment is a common task for developers building cloud-native applications. Whether you need to save a file to a local disk, process it in memory, or stream it directly to a client, the official @azure/storage-blob SDK provides powerful, promise-based methods to handle these operations efficiently.

To interact with your blobs, you must initialize a BlobServiceClient and then get a ContainerClient and BlobClient . javascript
