![]() The server is set to listen on the specified port and host name. The createServer() method of http creates a new HTTP server and returns it. Node.js has a fantastic standard library, including first-class support for networking. This code first includes the Node.js http module. To run this snippet, save it as a server.js file and run node server.js in your terminal. The most common example Hello World of Node.js is a web server: const http = require ( ' node:http ' ) const hostname = ' 127.0.0.1 ' const port = 3000 const server = http. In Node.js the new ECMAScript standards can be used without problems, as you don't have to wait for all your users to update their browsers - you are in charge of deciding which ECMAScript version to use by changing the Node.js version, and you can also enable specific experimental features by running Node.js with flags. Node.js has a unique advantage because millions of frontend developers that write JavaScript for the browser are now able to write the server-side code in addition to the client-side code without the need to learn a completely different language. This allows Node.js to handle thousands of concurrent connections with a single server without introducing the burden of managing thread concurrency, which could be a significant source of bugs. When Node.js performs an I/O operation, like reading from the network, accessing a database or the filesystem, instead of blocking the thread and wasting CPU cycles waiting, Node.js will resume the operations when the response comes back. Node.js provides a set of asynchronous I/O primitives in its standard library that prevent JavaScript code from blocking and generally, libraries in Node.js are written using non-blocking paradigms, making blocking behavior the exception rather than the norm. This allows Node.js to be very performant.Ī Node.js app runs in a single process, without creating a new thread for every request. Node.js runs the V8 JavaScript engine, the core of Google Chrome, outside of the browser. It is a popular tool for almost any kind of project!
