## Description

go-socket.io is a Go implementation of the Socket.IO protocol used to build real-time, bidirectional, and event-driven communication between servers and clients. It functions as a communication framework that manages persistent connections and maps incoming network packets to specific handler functions to execute application logic.

The library enables horizontal scaling of real-time connections through a distributed pub/sub adapter, which synchronizes events across multiple server instances using an external data store. It ensures reliability across different network environments by automatically negotiating transport layers between websockets and long-polling.

The framework provides tools for organizing communication through namespaces and rooms, allowing for logical partitioning and targeted broadcasting to specific subsets of users. It also includes capabilities for connection lifecycle management, session-based context storage, and an asynchronous acknowledgment pattern to track the successful receipt of data packets.
