In January 2010, Node.js came up with a package manager which is also known as NPM (it is one of the largest ecosystems of open source libraries), that helped developers by making it easier to publish and share the source code. When Node.js was released, it only supported operating systems like Mac OS X and Linux. The creation of Node.js has offered the developers the power to use JavaScript for unifying web app development and server-side scripting around a single programming language. Besides, it used to happen that codes could block the entire process, and to resolve the issues & improve the ability of businesses, Node.js has been the best option. It was created in 2009 and at that time servers used to struggle to handle high-volume connections. It comes with Web APIs that a software developer can use while creating a JavaScript engine. Node.js is a technology that is used for server-side programming and was primarily deployed for event-driven, non-blocking servers, like back-end API services and traditional websites but it was originally designed with the help of push-based and real-time architectures.īesides this, one thing to understand about Node.js is that it’s neither a library nor a framework but is a runtime environment. It is used by the developers for running web apps outside the client’s browser. Node.js is one of the most popular open-source, cross-platform runtime environments which process incoming requests in a loop which is also known as an event loop. Event loop, callback queue, setTimeout function internal working, event table, and message queue are the part of JavaScript runtime environment. JavaScript runtime environment executes front-end web applications in a browser and access to the window object. The v8 JavaScript engine implementation is independent of the runtime environment. Node js offers utility libraries used during the execution time. Some of the Most Popular Applications Built Using Node.js are.Handling Heavy Computing Tasks Reduces the Performance.Faster Processing and Event-Based Model.
