What this skill does
@azure/storage-blob (TypeScript/JavaScript) SDK for Azure Blob Storage operations — upload, download, list, and manage blobs and containers. Installation Current Version: 12.x Node.js: >= 18.0.0 Environment Variables Authentication DefaultAzureCredential (Recommended) Connection String StorageSharedKeyCredential (Node.js only) SAS Token Client Hierarchy Container Operations Create Container List Containers Delete Container Blob Operations Upload Blob (Simple) Upload from File (Node.js only) Upload from Stream (Node.js only) Upload from Browser Download Blob Download to File (Node.js only) Download to Buffer (Node.js only) List Blobs Delete Blob Copy Blob Blob Properties & Metadata Get Properties Set Metadata Set HTTP Headers SAS Token Generation (Node.js only) Generate Blob SAS Generate Container SAS Generate Account SAS Blob Types Block Blob (Default) Most common type for text and binary files. Append Blob Optimized for append operations (logs, audit trails). Page Blob Fixed-size blobs for random read/write (VHDs). Error Handling TypeScript Types Reference Best Practices 1. Use DefaultAzureCredential — Prefer AAD over connection strings/keys 2. Use streaming for large files — uploadStream/downloadToFile for files > 256MB 3. Set appropriate content types — Use setHTTPHeaders for correct MIME types 4. Use SAS tokens for client access — Generate short-lived tokens for browser uploads 5. Handle errors gracefully — Check RestError.statusCode for specific handling 6. Use IfNotExists methods — For idempotent container/blob creation 7. Close clients — Not required but good practice in long-running apps Platform Differences Feature Node.js Browser --------- --------- --------- StorageSharedKeyCredential ✅ ❌ uploadFile() ✅ ❌ uploadStream() ✅ ❌ downloadToFile() ✅ ❌ downloadToBuffer() ✅ ❌ uploadData() ✅ ✅ SAS generation ✅ ❌ DefaultAzureCredential ✅ ❌ Anonymous/SAS access ✅ ✅ When to Use This skill is applicable to execute the workflow or actions described in the overview. …
