Question 1

Should I use uvw or directly use libuv in my C++ project?

Accepted Answer

uvw is better if you prefer modern C++ idioms and type safety, while direct libuv usage suits those needing minimal overhead or already familiar with its C API. uvw adds a wrapper layer but maintains full compatibility.

Question 2

How do I set up uvw with CMake in my project?

Accepted Answer

Enable the UVW_BUILD_LIBS option in CMake to compile it as a static library, linking against uvw::uvw-static. For header-only usage, include uvw.hpp and set include paths manually, as per the build instructions.

Question 3

What C++ standard is required for uvw?

Accepted Answer

uvw requires at least C++17, as stated in the build requirements, to leverage features like smart pointers and type-safe interfaces. Ensure your compiler supports this standard.

Question 4

Is uvw thread-safe for concurrent applications?

Accepted Answer

uvw follows libuv's threading model; event loops are not thread-safe by default, but handles can be used across threads with proper synchronization, similar to native libuv usage.

Question 5

How does uvw handle memory leaks compared to raw libuv?

Accepted Answer

uvw uses shared pointers for automatic memory management of handles and requests, reducing manual cleanup errors, but still requires explicit closing of handles as per libuv rules to avoid leaks.

Question 6

Can I use uvw to build an HTTP server from scratch?

Accepted Answer

Yes, but uvw only provides TCP handles; you'll need to implement HTTP protocol logic yourself or use additional libraries, as it doesn't include high-level protocol support out-of-the-box.
