## What it is
uvw is a header-only (also available as a static/shared library) wrapper around libuv that exposes its C API through a modern, event-based C++17 interface. It stays faithful to libuv's semantics while providing RAII-style handles and event callbacks for loops, TCP, and other async I/O resources.

## Use cases
- write an async TCP server in modern C++
- wrap libuv event loop with a C++ API
- build cross-platform async I/O without raw libuv callbacks
- handle file system and network events with an event-based C++ library
- replace hand-written libuv C code with RAII C++ handles

## When to choose
- you want libuv functionality with a clean modern C++ API
- you prefer header-only integration or vcpkg availability
- you're building event-driven networked applications in C++17

## When to avoid
- you need a higher-level networking framework with abstractions beyond libuv
- your project doesn't use C++17 or modern C++
- you need coroutine-based async I/O rather than event callbacks
