Overview
A Dart package providing utilities for implementing clients and servers that adhere to the JSON-RPC 2.0 specification. It enables structured, stateless communication over transport layers like WebSocket or HTTP, supporting method calls, notifications, and error handling. The package is designed for developers building RPC-based services or integrating with existing JSON-RPC endpoints. It offers a clean API for encoding and decoding messages, managing requests and responses, and handling asynchronous operations. Ideal for tools, IDEs, or backend services requiring remote procedure calls.
Use cases
- Building RPC clients for external APIs
- Implementing server-side JSON-RPC endpoints
- Integrating with language servers (e.g., LSP)
- Enabling real-time communication in web and mobile apps
- Creating tooling for development environments
Key features
- Supports JSON-RPC 2.0 protocol
- Flexible transport layer integration

- Error and notification support
- Asynchronous message processing
Suitable for
- Developers building language servers
- Tooling and IDE extensions
- Backend services needing remote calls
- Cross-platform applications using RPC
- Real-time data exchange systems
Considerations
- Requires understanding of JSON-RPC 2.0 spec
- Not suitable for simple HTTP APIs
- Needs proper error handling in async flows
