Install: brew install uvw

About:
Uvw is a header-only C++ wrapper for libuv that abstracts the low-level C API into a modern, object-oriented interface. It simplifies asynchronous I/O operations by using an event-driven model similar to Node.js, making it easier to build high-performance network applications. The library requires no external dependencies beyond libuv and integrates seamlessly into existing C++ projects via single-header inclusion.

Key Features:

Header-only design with zero dependencies beyond libuv
Modern C++11/14/17 API with RAII and event emitter patterns
Lightweight abstraction over libuv's core (handles, requests, loops)
Cross-platform support (Linux, macOS, Windows, BSD)

Use Cases:

Building high-performance TCP/UDP servers and clients
Creating asynchronous file system operations
Implementing real-time applications like chat servers or game backends
Wrapping existing C++ applications with non-blocking I/O

Alternatives:

Boost.Asio – More comprehensive but heavier; requires Boost ecosystem; Uvw is lighter and libuv-focused
libuv (C API) – Lower-level C interface; Uvw provides safer, more idiomatic C++ bindings
Seastar – Framework for high-throughput apps; Uvw is simpler and suitable for single-node async I/O
