Prerequisites: Before creating the Node.js app It also has best-in-class dependency resolution. The node package manager (NPM) provides access to many of reusable packages.As Javascript is on both sides, client-side and server-side allows less time spent dealing with context shifts between languages.Great performance by optimizing throughput and scalability in the web app and also a good solution for real-time web applications.Asynchronous or non-blocking means, handling events without interrupting the main thread.It can handle many requests concurrently using Event Loop, for each connection, the callback is fired, but if there is no work to be done Node will remain asleep.Node.js is Event-driven, non-blocking (asynchronous) I/O, Non-blocking execution enables it one of the fastest language for building web applications today.ItвЂ™s an environment where the language can get interpreted. running directly on a computer or server OS). The runtime is basically enabled us to use javascript outside of a browser context (i.e.

The creator of Node.js, Ryan Dahl, took ChromeвЂ™s V8 engine and built a runtime for it to work on a server.

The browserвЂ™s engine like ChromeвЂ™s V8, MozillaвЂ™s SpiderMonkey, IEвЂ™s Chakra takes JavaScript code and compiles it into the machine code. We can develop various types of applications like Command line applications, Web applications, REST API and Web server, etc. Node.js allows building scalable server-side applications using JavaScript. Node.jsВ® is a JavaScript runtime built on ChromeвЂ™s V8 JavaScript engine. Node.js is an open-source, cross-platform, runtime environment that enables developers to write server-side applications in javascript. So LetвЂ™s start with some important concepts of Node вЂ“ Express app with an introduction of Node.js. Here we will start our discussion by building an understanding of Nodejs concepts like what is node.js? How does node.js work? its benefits and then create our app. I will provide a step by step detailed guide with examples and a required screenshot of code which will help you to understand the code and concepts.
