Libuv is a multi-platform C library that provides support for asynchronous I/O based on event loops. It is designed to enable non-blocking, event-driven operations through its full-featured event loop and various asynchronous primitives. These include asynchronous TCP and UDP sockets, DNS resolution, file and file system operations, child processes, and threading and synchronization primitives[1][3][6][7].
Originally developed for use in Node.js, libuv is crucial for handling the I/O operations that allow Node.js to perform efficiently in networked applications. It abstracts away the underlying platform-specific I/O details, providing a uniform API across different operating systems. This makes Node.js suitable for developing scalable network applications that are capable of handling many concurrent connections simultaneously[1][5][6].
In Node.js, libuv integrates directly with the V8 JavaScript engine, enabling it to manage the event loop and all related asynchronous operations. This integration is essential for Node.js's non-blocking, event-driven architecture, allowing it to handle multiple I/O operations in the background without interrupting the main JavaScript thread[2][5][12].
Furthermore, libuv includes a thread pool that can handle operations that are too CPU-intensive to run on Node.js's main thread, thus preventing ...
