What is @azure/storage-blob?

The @azure/storage-blob npm package is designed for working with Azure Blob Storage. It provides a comprehensive set of features to interact with Azure Blob Storage, including uploading and downloading blobs, managing containers, and handling blob metadata and properties. This package is part of the Azure SDK for JavaScript.

What are @azure/storage-blob's main functionalities?

Uploading blobs

This code sample demonstrates how to upload data to a blob in Azure Blob Storage. It involves creating a BlobServiceClient, getting a reference to a container, and then uploading data to a blob within that container.

const { BlobServiceClient } = require('@azure/storage-blob');
const blobServiceClient = BlobServiceClient.fromConnectionString(process.env.AZURE_STORAGE_CONNECTION_STRING);
const containerClient = blobServiceClient.getContainerClient('my-container');
const blockBlobClient = containerClient.getBlockBlobClient('my-blob');
await blockBlobClient.upload(data, data.length);

Downloading blobs

This code sample shows how to download the content of a blob. It involves creating a BlobServiceClient, getting a container client, and then downloading the blob's content using the block blob client.

const { BlobServiceClient } = require('@azure/storage-blob');
const blobServiceClient = BlobServiceClient.fromConnectionString(process.env.AZURE_STORAGE_CONNECTION_STRING);
const containerClient = blobServiceClient.getContainerClient('my-container');
const blockBlobClient = containerClient.getBlockBlobClient('my-blob');
const downloadBlockBlobResponse = await blockBlobClient.download(0);
const downloadedContent = await streamToString(downloadBlockBlobResponse.readableStreamBody);

Listing blobs in a container

This example demonstrates how to list all blobs in a specific container. It involves creating a BlobServiceClient, obtaining a container client, and iterating over the blobs in the container, printing out their names.

const { BlobServiceClient } = require('@azure/storage-blob');
const blobServiceClient = BlobServiceClient.fromConnectionString(process.env.AZURE_STORAGE_CONNECTION_STRING);
const containerClient = blobServiceClient.getContainerClient('my-container');
for await (const blob of containerClient.listBlobsFlat()) {
  console.log(`Blob name: ${blob.name}`);
}
