RPC WebSocket

RPC WebSocket is a wrapper for standard WebSocket that adds support for message types, RPC calls, and before/after send/receive event hooks. Version 0.7.6 is the latest release; the package has not seen updates since 2016 and is in maintenance mode with known issues. It provides a lightweight alternative to Socket.io for simple RPC over WebSocket, lacking built-in reconnection or authentication. Works in both Node.js and browser environments. Note: The package is not actively maintained and may have compatibility issues with modern WebSocket APIs and module systems.
