Uses of Nodejs

Node.js is an open-source and cross-platform runtime environment for executing JavaScript code outside a browser. Node.js is used to build back-end services like APIs like Web App or Mobile App. It’s used in production by large companies such as Paypal, Uber, Netflix, Walmart, and so on.

Uses of NodeJs:

In Browser Games:

NodeJS helps in creating a real-time application where we can create games for browsers. Nodejs in conjunction having g Socket.io and HTML leads to creating a great game and good design.

Collecting data inputs:

It is highly used in collecting data provided by any resource. It is mainly used in collecting the form data from the browser, and then it sends the data to the backend of the database where all data gets stored and can be again fetched by NodeJs anytime.

In streaming media:

Whenever a user wants to upload any type of media e.g.: Audio or Video it can be done by the use of NodeJs. NodeJs help these media in processing and it makes the fastest uploading and processing journey. This saves a lot of time and makes media available and accessible at fast speed from anywhere and anytime.

In online chat rooms:

In today’s world, people do like to connect with each other in online mode, and they need a platform through which they can connect with each other. That platform must have some basic features like a chat section, voice sharing, media sharing, etc. To achieve these all features with high speed of transformation and accessible NodeJs come into play. It is mainly used in gaming as there is always a room or section where a specific amount of people get to join and they do play games.

In MERN stack:

In this N stands for NodeJs, It is a combination of stacks that is used by developers to develop any type of web application. Where NodeJs get combined with M(Mongodb) for efficient work output.

In Real-Time Applications:

NodeJs is highly used in creating a real-time application. Whenever there is a need for highly scalable and low latency applications then NodeJs is used. e.g.: Linkedln, PayPal.

In the creation of API:

Whenever an application is created then there must be a backend where the logic and the processing of data occurs. In this NodeJs helps in the creation of that data processing system mean API. which basically integrates the frontend and backend of an application.

Features of Node.Js:

NodeJs has some extra featues which makes it more important and useful.

• Asynchronous : NodeJs is asynchronous in nature means only a single thread handles the request at one time, means if a request is made by the user then it goes to the server and it sends response to the client. and after completion of this process now thread is available to take another new request.
• Single threaded: NodeJs is single threaded and it follow “Single Threaded Event Loop Model” architechture, which helps for multi request handeling.
• Event based: It has many events which handles many process. In this callback function is used.
• NPM(Node Package Manager): It is highly used with NodeJs as many od modules who does specific task only present in npm.
• Highly scalable: As it works asynchronously. only single thread is used for every request and response.

Conclusion:

JavaScript is used everywhere as it provides many features mentioned above. Also is provided so much aspects for the web devlopemrnt field. Because of this use of server is possible. It provide high scalability and low latency to the application.
