The backend has been developed in a completely new way thanks to node.js. This is a program that allows a developer to utilize JavaScript even on the server side. Formerly, JavaScript was only used in client-side scripts but with the use of Node.js, server applications can be developed in the very same language that browsers use. This has eased development for a number of coders who already possess JavaScript skills.
Node.js is a free software and a multiplatform enabling runtime that runs JavaScript scripts in the server environment. Its architectural structure is the V8 engine used in the Google chrome browser making it effective and reliable. Unlike conventional server-side programming systems which depend on threads for servicing more than one request, Node.js works on a single threaded and event based mechanism. This characteristic enables it to serve a large number of requests at the same time which is helpful in the development of web applications that have to be scaled.
Node.js relies heavily on a non-blocking event-driven architecture, which is ideal for developing distributed networking applications. It is also good at processing input and output (I/O) requests, which are common while carrying out web-based tasks, including writing and reading files, making HTTP requests, and working with databases.
The fact that it is non-blocking has an important advantage for software like real-time chat systems, live data streaming, and APIs, which need to maintain a high number of concurrent connections, over time. So, with every user request being catered to at the same time, Node.js seems to be doing tasks considerably quicker than what is the case with server-side languages where each task is supposed to finish before the next one can be started.
1. JavaScript Everywhere : One of the primary advantages of using Node.js is that developers can utilize JavaScript in both the frontend and backend. This negates the need to master multiple languages for various sections of an application. Users of JavaScript can utilize it in the entire stack which would lead to reduced complexity in the development processes and easier code maintenance.
2. Performance : Node.js is based on the V8 engine, which compiles JavaScript directly into a machine code, accelerating the execution speed. Also, because it is non-blocking and event-driven, Node.js is able to manage thousands of active connections simultaneously without compromising performance.
3. Scalability : An application built on Node.js is highly scalable in addition to being expandable. It is event-driven and able to manage several database requests at the same time. This is quite useful in the applications, wherein high throughput is required such as APIs or real time services.
4. NPM (Node Package Manager) : A package manager is built into Node.js and which is called NPM, a utility that enables one to access thousands of free libraries and modules which can be used in one's applications. This allows one to quickly and effortlessly add in functionalities such as database capabilities or user authentication without having to create it from square one.
5. Real-time Data : Applications that handle real time data would benefit greatly from the use of Node.js. The architecture of Node.js is event driven, and therefore, it can be used in any time-based application such as online chats, collaboration tools, online games etc. Furthermore, the capability of handling numerous connections at the same time with minimum cost applies to these situations perfectly.
6. Community Support : One of the best features of Node.js is its lively and vigorous community. The community is angry with a huge number of tutorials, documentation, and open source projects which can be used in handy when looking for solutions. The more the users in the Node.js ecosystem, the better the improvement of the platform.
1. Asynchronous and Nonblocking : Working on a nonblocking asynchronous mode, Node.js can concurrently execute several requests. Unlike conventional servers that must make use of several threads to satisfy requests, Node.js server makes use of a single thread and is able to attend to a number of requests simultaneously.
2. Event Loop : The event loop retrieves the task from the application and assigns it the system and the task is started, And the event loop jumps to the next task. After finishing the task, it fires an event to the application.
3. Single-Threaded Model : Even though Node.js is capable of supporting many simultaneous connections, it does so on a single thread which makes the cost of maintaining several threads low. For input/output intense applications, this makes the server light-weighted and fast.
4. Cross-platform : Node.js runs on a number of operating systems including Windows, Linux and Mac OS X. Thanks to this feature, applications are easily developed and maintained in different systems without substantial changes.
5. Streams : Node.js supports streams with the help of which data can be handled in chunks instead of fetching it all at once. This feature is significant for the developers who have to deal with large-scale data such as processing of huge files or real-time transmission of data to clients.
6. HTTP Module : With the backend development incorporating the built in HTTP module provided by Node.js, developing web servers and APIs has never been easy. Rather than complex system architectures, starting with simple web servers that handle the HTTP protocols can be set up with ease.
7. JSON Handling : JSON or JavaScript Object Notation, is a popular data format used in client-server interaction and is supported by Node.js out of the box. This feature in particular allows for easy development of RESTful APIs on Node.js due to its compatibility with JSON.
8. Robust Ecosystem : A lot of packages and libraries are present in the Node.js which can be easily downloaded from NPM, making the development process easy. If you are working with databases, authentication, sending emails, then most probably you will find a relevant package already available.

What is Node.js?
Node.js is a platform that allows Javascript code to be executed on the server side as opposed to only the browser. In other words, it allows Javascript for server-side programming. The V8 JavaScript Engine, usually associated with Google, is used because it compiles Javascript into machine code for fast processing.Node.js relies heavily on a non-blocking event-driven architecture, which is ideal for developing distributed networking applications. It is also good at processing input and output (I/O) requests, which are common while carrying out web-based tasks, including writing and reading files, making HTTP requests, and working with databases.
How Does Node.js Work?
Each Node.js application follows an event-driven style architecture which makes it easier to perform non-blocking actions. It does not wait for an I/O request to complete, like the other applications, rather, it processes multiple tasks at a time. To do so, it utilizes an event loop. The moment an I/O request has been completed, an event is fired to indicate that there is now a completed request that the application can use.The fact that it is non-blocking has an important advantage for software like real-time chat systems, live data streaming, and APIs, which need to maintain a high number of concurrent connections, over time. So, with every user request being catered to at the same time, Node.js seems to be doing tasks considerably quicker than what is the case with server-side languages where each task is supposed to finish before the next one can be started.
