NetConn

NetConn is a cross-platform networking library and abstraction layer designed to simplify the development of networked software by providing a unified interface for establishing, maintaining, and terminating connections across multiple transports.

Its core features include asynchronous input/output via an event-driven scheduler, support for traditional TCP and UDP transports, and encrypted channels through TLS/SSL. It also provides protocol adapters such as WebSocket and HTTP/2, multiplexed streams, and built-in reconnection with exponential backoff. Language bindings exist for several popular languages, enabling integration in C, C++, Python, Java, and JavaScript projects.

Architecture: NetConn uses a modular design with a central event loop, protocol handlers, and transport backends. A standardized connection API covers lifecycle operations (open, upgrade, send, receive, close), while a middleware-style extension model allows authentication, logging, and telemetry components to be layered without altering application code. The core emphasizes thread safety and reference counting to support multi-threaded environments.

Use cases: It is commonly employed in server and client applications that require robust connection management, such as microservices, real-time messaging, IoT gateways, and online games. The library focuses on resilience and observability, offering features like automatic reconnect, backoff strategies, and connection pooling. Performance-sensitive workloads should weigh the overhead of abstraction against latency requirements.
