JavaScript is the global programming language for creating online apps. It is also utilised in both frontend (client-side) and backend (server-side) development. However, the fact that the beauty of the front-end is dependent on the back-end cannot be denied. This is where NodeJS comes into play. Because of its extensive and diverse capabilities, NodeJS is the best choice for server-side application development. NodeJS is used for server-side programming by firms such as Uber, PayPal, Netflix, Walmart, Twitter, LinkedIn, and even NASA.

What is NodeJS?
NodeJS is an event-driven JavaScript runtime that is built on Chrome's V8 engine and is used to create traditional and scalable server-side web apps and back-end APIs.
It is open-source and runs in a "Single-Threaded" environment. Handling several clients at the same time is referred to as single-threaded. NodeJS also provides lightning-fast client-server communication and data processing. Developers may also exchange code and reuse it for both the frontend and backend components of the programme, making it valuable to utilise.
Why NodeJS?
Real-Time Apps
Real-time apps allow clients and servers to communicate in real time. Using NodeJS with Web-Sockets makes it simple for developers to create one. NodeJS makes it easier to handle many client requests and allows for code exchange and re-use of library scripts.
Data Streaming
Because of its lightweight and quick processing capabilities, companies such as Netflix employ NodeJS for data streaming. The streams allow users to pipe requests to one another, resulting in data streaming to the endpoint. With I/O bound apps, NodeJS manages data streams. The procedure involves file uploading and data streaming, which we then process online. This might be applied to real-time audio or video streaming as well. Streams are classified into four types: written, readable, duplex, and transform.
Microservice Architecture
An architecture that considers and serves every application purpose. NodeJS is extremely adaptable, allowing it to create both microservice-based and server-less applications. You can easily break your programme into portions, assign each microservice to a team, and develop one section independently of the others. As a result, the apps become lightweight and stateless, making server-less architecture integration simple.

NodeJS Packages
NPM is theNode package manager, and it provides packages or modules that may be used to implement tiny tasks like adding real-time features, dealing with databases, and so on. It's used to find, install, publish, and create node programmes. The command "npm install package_name" installs a specific package that will be needed during application development. Although there are over 1300 packages and the number is growing by the day, here are a few that developers can use to execute tasks quickly and efficiently.
Express
Express is a web application framework written on NodeJS. It is commonly used to develop and publish applications. It is fast, unbiased, and comes with a large set of HTTP helpers. It is also well-known for its API development.
MongoDB
It's a NodeJS MongoDB driver that gives API access to MongoDB databases. MongoDB, like MySQL, is a relational database that uses structured query language to access data. It protects data integrity and meets security and regulatory requirements.
Webpack
Webpack is a module bundler that bundles HTML, CSS, and JS files for use in browsers. It aids in producing clean, organised, and split code based on the developer's choices.
Socket.io
Socket.io supports real-time, bi-directional, and event-driven communication, as well as two-way real-time connections. Socket is typically made up of a Nodejs server and a JS client library.
