There are also several packages available for interacting with other languages or runtime environments like Microsoft.NET. Connect, Express.js, Socket.IO, Feathers.js, Koa.js, Hapi.js, Sails.js, Meteor, Derby, and numerous other frameworks fall under this category. Web frameworks have been built by the open-source community to speed up the creation of apps. The majority of them are maintained on the npm website. Numerous open-source libraries are available for Node.js.

Another well-known language, JavaScript, made Node.js available to the web development community.Īmong the businesses that employ Node.js software are GoDaddy, Groupon, IBM, LinkedIn, Microsoft, Netflix, PayPal, SAP, Walmart, Yahoo!, and Amazon Web Services. It is adept at using standard internet protocols, including HTTP, DNS, and TCP. Since Google's V8 JavaScript engine was open-sourced under the BSD license, Node.js was built on top of it. Node.js combine JavaScript's ease of use and the strength of Unix network programming. Without threading, developers can build scalable servers using an abridged version of event-driven programming that uses callbacks to indicate when a task is finished. Node.js builds quick web servers in JavaScript by integrating event-driven programming into web servers. These design decisions attempt to maximize performance and scalability for real-time web applications with numerous input/output activities, for example, real-time communication programs and browser games. The event-driven design of Node.js supports asynchronous I/O.

Thus, Node.js symbolizes a 'JavaScript everywhere' paradigm, bringing web application development under a single programming language rather than segregating it across server-side and client-side scripting languages. Node.js, an open-source, cross-platform back-end JavaScript runtime environment that operates on a JavaScript Engine and executes JavaScript code outside a web browser, develops scalable network applications.ĭevelopers use JavaScript to create command-line tools and for server-side scripting, which produces dynamic web page content on the server before the page is transmitted to the user's web browser through Node.js.
