Explain Node.js Architecture?


There are four building blocks that constitute Node.js. First, Node.js encapsulates libuv to handle asynchronous events and Google’s V8 to provide a run-time for JavaScript. Libuv is what abstracts away all of the underlying network and file system functionality on both Windows and POSIX-based systems like Linux, Mac OS X and Unix. The core functionality of Node.js, modules like Assert, HTTP, Crypto, etc., reside in a core library written in JavaScript. The Node.js bindings, written in C++, provide the glue connecting these technologies to each other and to the operating system.
