2 
3SDK packages and quick start examples for Azure Storage services.

5## Storage SDKs by Language
6 
7| Language | Blob | Queue | File Share | Data Lake |
8|----------|------|-------|------------|----------|
9| .NET | `Azure.Storage.Blobs` | `Azure.Storage.Queues` | `Azure.Storage.Files.Shares` | `Azure.Storage.Files.DataLake` |
10| Java | `azure-storage-blob` | `azure-storage-queue` | `azure-storage-file-share` | `azure-storage-file-datalake` |
11| JavaScript | `@azure/storage-blob` | `@azure/storage-queue` | `@azure/storage-file-share` | `@azure/storage-file-datalake` |
12| Python | `azure-storage-blob` | `azure-storage-queue` | `azure-storage-file-share` | `azure-storage-file-datalake` |
13| Go | `azblob` | `azqueue` | `azfile` | `azdatalake` |
14| Rust | `azure_storage_blob` | `azure_storage_queue` | - | - |
15 
16## Installation Commands
17 
18| Language | Install Blob SDK + Identity |
19|----------|-----------------------------|
20| .NET | `dotnet add package Azure.Storage.Blobs` `dotnet add package Azure.Identity` |
21| Java | Maven: `com.azure:azure-storage-blob` `com.azure:azure-identity` |
22| JavaScript | `npm install @azure/storage-blob @azure/identity` |
23| Python | `pip install azure-storage-blob azure-identity` |
24| Go | `go get github.com/Azure/azure-sdk-for-go/sdk/storage/azblob github.com/Azure/azure-sdk-for-go/sdk/azidentity` |
25| Rust | `cargo add azure_storage_blob azure_identity` |
26 
27## Quick Start Examples
28 
29All examples use `DefaultAzureCredential` for authentication, which is recommended for **local development only**. In production, use `ManagedIdentityCredential` — see [auth-best-practices.md](auth-best-practices.md). Rust uses `DeveloperToolsCredential` as it doesn't have a `DefaultAzureCredential` equivalent.

31**Python** - Upload Blob:
32```python
33from azure.identity import DefaultAzureCredential
34from azure.storage.blob import BlobServiceClient
35 
36service = BlobServiceClient(account_url="https://ACCOUNT.blob.core.windows.net/", credential=DefaultAzureCredential())
37container = service.get_container_client("my-container")
38blob = container.get_blob_client("my-blob.txt")
39blob.upload_blob(b"Hello, Azure Storage!", overwrite=True)
40```
41 
42**JavaScript** - Upload Blob:
43```javascript
44import { DefaultAzureCredential } from "@azure/identity";
45import { BlobServiceClient } from "@azure/storage-blob";
46 
47const client = new BlobServiceClient("https://ACCOUNT.blob.core.windows.net/", new DefaultAzureCredential());
48const container = client.getContainerClient("my-container");
49const blob = container.getBlockBlobClient("my-blob.txt");
50await blob.uploadData(Buffer.from("Hello, Azure Storage!"));
51```
52 
53**C#** - Upload Blob:
54```csharp
55using Azure.Identity;
56using Azure.Storage.Blobs;
57 
58var client = new BlobServiceClient(new Uri("https://ACCOUNT.blob.core.windows.net/"), new DefaultAzureCredential());
59var container = client.GetBlobContainerClient("my-container");
60var blob = container.GetBlobClient("my-blob.txt");
61await blob.UploadAsync(BinaryData.FromString("Hello, Azure Storage!"), overwrite: true);
62```
63 
64**Java** - Upload Blob:
65```java
66import com.azure.identity.*;
67import com.azure.storage.blob.*;
68import com.azure.core.util.BinaryData;
69 
70BlobServiceClient client = new BlobServiceClientBuilder()
71    .endpoint("https://ACCOUNT.blob.core.windows.net/")
72    .credential(new DefaultAzureCredentialBuilder().build())
73    .buildClient();
74BlobContainerClient container = client.getBlobContainerClient("my-container");
75BlobClient blob = container.getBlobClient("my-blob.txt");
76blob.upload(BinaryData.fromString("Hello, Azure Storage!"), true);
77```
78 
79**Go** - Upload Blob:
80```go
81package main
82 
83import (
84    "context"
85 
86    "github.com/Azure/azure-sdk-for-go/sdk/azidentity"
87    "github.com/Azure/azure-sdk-for-go/sdk/storage/azblob"
88)
89 
90func main() {
91    cred, _ := azidentity.NewDefaultAzureCredential(nil)
92    client, _ := azblob.NewClient("https://ACCOUNT.blob.core.windows.net/", cred, nil)
93 
94    data := []byte("Hello, Azure Storage!")
95    _, _ = client.UploadBuffer(context.Background(), "my-container", "my-blob.txt", data, nil)
96}
97```
98 
99**Rust** - Upload Blob:
100```rust
101use azure_identity::DeveloperToolsCredential;
102use azure_storage_blob::{BlobClient, BlobClientOptions};
103 
104let credential = DeveloperToolsCredential::new(None)?;
105let blob_client = BlobClient::new(
106    "https://ACCOUNT.blob.core.windows.net/",
107    "my-container",
108    "my-blob.txt",
109    Some(credential),
110    Some(BlobClientOptions::default()),
111)?;
112let data = b"Hello, Azure Storage!";
113blob_client.upload(None, data.to_vec().into()).await?;
114```
