INTRODUCTION With the emergence of numerous popular frameworks such as bootstrap, Angular JS, and others, the modern online application has come a long way. These frameworks are all built on top of the well-known JavaScript framework. However, there was a hole in designing server-based apps, which is where learn Node.js came into play. Although Node.js is built on the JavaScript framework, it is a backend development framework used to create server-side applications. Throughout the lesson, we'll look at the Node.js tutorial for beginners in-depth and see how we can use it to build server-based applications.
What is Node JS Node.js is a cross-platform, open-source runtime environment for developing server-side web applications. Applications created with Node.js are written in JavaScript and can operate on various operating systems. Node.js is a real-time online application framework that uses an event-driven architecture and a non-blocking Input/Output API to improve throughput and scalability. The frameworks available for web development for a long time were all based on a stateless approach.
Why Use Node JS In the following chapters, we'll look at the actual value of Node.js, but first, let's look at what makes this framework so popular. Most applications are built using a stateless request-response framework over time. In these kinds of apps, it's up to the developer to make sure to write the correct code to keep the user's web session alive as they work with the system. You may now work in real-time and have two-way communication with Node.js web applications. The state is preserved, and the communication can be initiated by either the client or the server.
Features of Node JS 1. This (req, res) shows the request and response commands. 2. The V8 JavaScript Runtime engine 3. Concurrent request handling 4. Node JS Uses Javascript Library
When you require a lot of parallelisms but not a lot of devoted CPU time, Node.js is an intelligent choice. Because Node.js is based on javascript, it works best when creating client-side applications that use the same framework. In the coming tutorials, we discuss the benefits of Node.js.
