json-rpc-ws

A WebSocket transport library for JSON-RPC that enables asynchronous bidirectional requests and responses over WebSocket connections. Version 7.0.1 supports Node.js and browser environments via separate entry points. It provides a simple API with server and client creation, method exposure, and callback-based request/response handling. Key differentiators: uses the popular 'ws' library for Node, supports both server and client in one package, and offers a lightweight abstraction over raw WebSocket messaging.
