uWebSockets/uWebSockets
UWebSockets
uWebSockets is a C++ networking framework that serves as a high-performance WebSocket server library, HTTP web server, and pub-sub messaging system. It provides the infrastructure necessary to handle standard web requests and maintain low-latency, bidirectional connections between clients and servers.
The framework is distinguished by its use of template meta-programming for compile-time optimization and zero-copy buffer management to minimize memory latency. It utilizes a backend-agnostic event loop and static route resolution to process network traffic with minimal runtime overhead.
The project covers a broad range of capabilities including parameterized URL routing, topic-based message broadcasting via a publish-subscribe model, and real-time data streaming. It also implements secure network communication through the Transport Layer Security 1.3 protocol.
The build process allows for the custom selection of event loop and cryptography libraries to meet specific target platform requirements.
