Overview

The DID Spaces SDK for JavaScript (@blocklet/did-space-js) provides a comprehensive set of tools for developers to interact with DID Spaces. This SDK simplifies operations related to decentralized object storage, data backup, and advanced features, enabling you to build powerful decentralized applications on ArcBlock's DID infrastructure. It is available on npm.

Key Features#

• Object Management: Programmatically upload, retrieve, list, and delete files and directories.
• Folder Synchronization: Efficiently sync local folders with a DID Space using push, pull, and incremental sync commands.
• Backup and Restore: Securely back up and restore Blocklet data.
• NFT Management: Handle NFT-related objects, such as display assets.
• Rich Previews: Create and manage preview metadata for your objects.
• Audit Logging: Access and manage activity logs for various operations within your space.

Core Concepts#

To use the SDK effectively, you should understand its foundational components:

• Client: The SpaceClient is the main entry point for all operations. See the Client section for more details.
• Commands: All actions are encapsulated in command objects that inherit from a common BaseCommand. Learn more in the Base Command section.
• Security: Interactions are secured through request signing and delegation. Details are available in the Security section.

Architecture#

The DID Spaces SDK is designed with a modular and extensible architecture to separate concerns and simplify development.

Utilities#

The SDK includes a collection of helper functions for common tasks like DID validation, HTTP requests, error handling, and hashing. These utilities support the core command functionality and are also available for use in your application. For a complete list, see the Utilities section.
