This guide covers the three primary ways to handle downloads: saving to a local file, reading into a memory buffer, and streaming for high performance. Prerequisites Before coding, ensure you have the following: An Azure account with an active Subscription.
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("my-container-name"); const blobClient = containerClient.getBlobClient("sample-file.txt"); Use code with caution. 2. Download to a Local File
Streaming is the most memory-efficient way to handle large files. Instead of loading the entire file into RAM, you "pipe" the data from Azure directly to its destination (like an HTTP response or a write stream). javascript
For client-side downloads, don't expose your connection string. Generate a temporary SAS URL so the browser can download directly from Azure.
async function downloadToFile() { const downloadPath = "./downloaded-file.txt"; await blobClient.downloadToFile(downloadPath); console.log(`Blob downloaded to ${downloadPath}`); } Use code with caution. 3. Download to a Buffer (Memory)
