Nodejs is use as middle layer(server) in project communicate front end and database. Node.js is an open source server environment Node.js is free Node.js runs on various platforms (Windows, Linux, Unix, Mac OS X, etc.) Node.js uses JavaScript on the server Node.js uses asynchronous programming! A common task for a web server can be to open a file on the server and return the content to the client. Here is how PHP or ASP handles a file request: Sends the task to the computer's file system. Waits while the file system opens and reads the file. Returns the content to the client. Ready to handle the next request. Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.
