libuv
An underlying support library for cross-platform asynchronous I/O, written in C, which wraps operating system event notification mechanisms (epoll, kqueue, IOCP) and provides a unified asynchronous API; it is the foundation for the implementation of the Node.js event loop.
Timeline (last 90 days)
libuv is a cross-platform asynchronous I/O library written in C that wraps Linux's epoll, macOS's kqueue, and Windows's IOCP, providing a unified asynchronous API upward.
libuv's thread pool has 4 threads by default, used for blocking operations such as file I/O and DNS resolution.
Node.js's event loop is implemented within libuv and includes multiple phases such as timers, pending callbacks, poll, check, and close callbacks.
Compared with similar libraries such as glib and libuv, libevent has a longer history, a smaller size, and better support for old platforms and cross-compilation.
FSEvents and Grand Central Dispatch on macOS, as well as the BSD/macOS platform implementation of libuv, are all built on top of kqueue
Node.js自2009年诞生，基于V8引擎和libuv事件循环架构
