Node.js is a popular platform for building web applications as it helps manage many concurrent connections with high throughput and low latency. Node.js has been used by some of the biggest tech companies like Netflix, Uber, eBay, NASA, etc. Moreover, Node.js uses an event-driven and non-blocking I/O strategy to unlock seamless scalability and excellent speed.
MongoDB and Express.js are often used in conjunction with Node.js for web development. The best part about Node.js is that developers get extensive documentation covering almost everything related to Node.js.
Node.js Delivers Efficiency, Speed, and Security:
The entire development paradigm is changing, and the demand for real-time applications is at an all-time high. E-commerce stores, gaming applications, chatbots, and audio and video streaming apps have made Node.js the most sought-after choice for app development.
In addition, Node.js offers flexibility to make the code easily manageable and reduce the overall development cost and time-to-market for the product.
When we talk about web applications, two things that are of utmost importance are security and speed. Node.js ensures both by providing various inbuilt modules that take care of common attack vectors. In addition, the community is constantly working on adding more security features to make Node.js more secure.
Many large organizations like Netflix, Walmart, and LinkedIn have built their applications using Node.js. The reason behind this is that Node.js can handle a large number of concurrent connections with high throughput and low latency. Moreover, Node.js offers high-level code reusability that helps in reducing the overall development time and cost.
In Node.js, everything is based on events, and this event-driven architecture helps develop highly scalable applications. However, as all the processes are asynchronous, it doesn’t wait for any I/O operation to complete. This helps in leveraging the maximum CPU and memory usage.
Moreover, Node.js uses a single-thread model with an event loop. This makes it easy to develop applications that handle many concurrent connections with high throughput. The best part is that all this happens without using multiple threads, which helps in reducing the overall complexity of the code. Therefore, you must know that all the Node.js explanations should include NPM (Node Package Manager).
NPM is the default package manager for Node.js, and it consists of a command-line interface that helps install, update, and manage node programs. It also provides an extensive online repository of various node programs that developers can easily access. NPM makes it easy to share the code and develop collaboration among multiple developers. It also takes care of various dependencies that are required for the project.
How To Setup Node.Js In Windows
Installing Node.js on Windows is a straightforward task. You need to visit the official Node.js website and download the installer file. The downloaded file is in the .msi format which can be installed by double-clicking on it.
Click on the Next button to see the following screen where you need to accept the license agreement. After receiving the license agreement, click the Next button, and you will see the following screen where you can customize the installation.
You should leave the default settings and click on the Next button. Once the installation is completed, click on the Finish button, and you will see the following screen that confirms successful installation.
Now, open the command prompt and type node -v to check the installed Node.js version. In addition, you should see the following output that confirms the successful installation of Node.js.
Use Cases of Node.js
Node.js is a full-fledged back-end solution that can be used to build scalable network applications. The following are some of the most popular use cases of Node.js:
Real-Time Chat Apps
One of the most popular use cases of Node.js is to build real-time chat applications. The reason behind this is that Node.js offers high scalability and low latency that are required for real-time applications. Moreover, various Node.js modules make it easier to build such applications.
APIs and Microservices
Node.js is also a popular choice for building APIs and microservices because it is easy to build lightweight and fast APIs using Node.js. Moreover, various tools and frameworks in Node.js make it easier to develop and deploy such APIs.
Another widespread use case of Node.js is to build IoT applications because Node.js is lightweight and can run on devices with limited resources. Moreover, various Node.js modules can be used to interact with different types of hardware.
Real-time dashboards are also popularly built using Node.js because Node.js offers the required scalability and low latency for such applications. Moreover, various tools and frameworks available in Node.js make it easier to develop and deploy such dashboards.

Node.js Tools and Frameworks
Node.js is a platform that is constantly evolving, and various tools and frameworks are being developed to make it more accessible and easier to use. The following are some of the most popular Node.js tools and frameworks:
Express.js is the most popular Node.js framework used for building web applications. It is a lightweight framework that provides features to simplify web application development.
Socket.io is a popular Node.js library that is used for building real-time applications. It simplifies the process of adding real-time functionality to web applications. Passport is a popular authentication middleware for Node.js that simplifies the authentication process.
Mongoose is a popular object data modeling (ODM) library for MongoDB and Node.js that simplifies the process of data validation, casting, and query building.
Nodemon is a utility that automatically restarts the Node.js application when any change is made to the code.
Following are Some Key Technical Aspects of Node.js Framework:
Asynchronous and Event-Driven
All APIs of Node.js are asynchronous i.e., non-blocking. It simply means a Node. the js-based server never waits for an API to return data. The server moves to the next API after calling it and a notification mechanism of Events handles the response from the previous API call.
Faster Process Execution
Single-Threaded but Highly Scalable
Node.js uses a single-threaded model with event looping. The event mechanism helps the server to respond in a non-blocking way and makes the server highly scalable as compared to traditional servers like Apache HTTP Server.
Node.js allows the developers to define their own modules. These modules can be further used as libraries in other applications. Moreover, Node Package Manager (NPM) owns the world’s largest software registry that contains more than 600,000 libraries and modules.
