AT Protocol enables decentralized social networking, designed by Bluesky Social. This repository provides a TypeScript reference implementation of the protocol, including client libraries, services, and lexicons. It addresses the challenges of building interoperable and scalable social platforms by offering a standardized framework for data transfer and identity resolution, utilizing TypeScript for robust and maintainable code.
Notable for its comprehensive TypeScript implementation covering various aspects of the AT Protocol, including API clients, cryptographic primitives, and data storage. The project's modular design with separate packages for different functionalities promotes code reusability and maintainability. It also features detailed documentation and interoperability test data to support other protocol implementations, fostering a collaborative ecosystem.
- API Clients: Provides TypeScript libraries for interacting with the AT Protocol, including data serialization and deserialization, simplifying client development.
- Services: Includes implementations for core services such as the Personal Data Server (PDS) and AppView, enabling the creation of functional social network backends.
- Lexicons: Defines canonical versions of lexicons for both
com.atproto.*andapp.bsky.*, facilitating standardized data structures across implementations. - Cryptography: Offers cryptographic signing and key serialization functionalities to ensure data integrity and secure communication.
- Test Data: Includes language-neutral test files for interoperability testing, supporting the correct implementation of the protocol specification.
- Developer Tools: Provides a Makefile to simplify development tasks such as dependency management, building, testing, and running local development environments.
- Interoperability Focus: Emphasizes facilitating interoperability between different social networks and applications built on the AT Protocol.
The project is actively maintained with recent commits and ongoing development. Extensive documentation is available, and a supportive community forum fosters discussion and collaboration. The repository also includes interoperability test data highlighting the progress in ensuring correct implementations. While the project is still under active development, it provides a reliable base for building on the AT Protocol.
This project benefits developers aiming to build decentralized social networks, enabling interoperability and fostering a more open social media landscape. It provides a comprehensive and well-documented reference implementation of the AT Protocol, allowing developers to quickly integrate with the protocol and build their own social applications. It offers a valuable alternative to centralized social media platforms by promoting data ownership and user control.
