    What is Nodejs Used for? Nodejs Use Cases

    Undoubtedly, a decade has passed since the initial release of the nodejs, it has gained immense popularity among developers for the fantastic development of web applications. Node.js development is special for backend developers. The reason why most of the tech giants use the node.js for development is that it is an open-source, and community-loved engine. As we all know, Node.js is a runtime built on the popular Chrome V8 JavaScript engine. Node.js comes from the JavaScript family that allows the developers to use the same programming on both the front-end and back-end.

    Node.js development is not only limited to web applications but also includes the development in the microcontrollers, REST APIs, static file servers, chatbots, queued I/O inputs, etc. Today, we will discuss the use cases of node.js development. But, before diving deeper into the world of the nodejs use cases, let’s first briefly understand the node.js development.

    What is Nodejs?

    Node.js is a run-time environment based on JavaScript, that can be used as frontend and backend. Talking about the origin of the Node.js platform, then it was created by the developer Ryan Dahl in the year 2009. Considering the popularity of the Node.js development on SimilarTech website, around 175k websites are developed using the node.js. The highest number of Node.js websites are developed in the United States (37,079) followed by Russia(12,079) and China(10,240).

    Examples of Nodejs Applications

    • Streaming applications
    • Chat applications
    • Command-line applications
    • Browser games
    • Embedded systems

    How Nodejs Works?

    Node.js is a highly customizable technology consisting of a server engine that uses the non-blocking event-based input/output model. Nodejs provides enhanced performance and agility, as it allows the translation of JavaScript code into the machine language. So, Node.js provides a run-time environment, in which JavaScript code moves fast in the server-to-client direction. As we all know, traditional web-serving techniques, it requires a separate thread for each request. But, in the case of Node.js, the scenario is completely changed. With the help of the non-blocking I/O model, it needs only a single thread to handle concurrent requests. To ensure the development speed and high-level of responsiveness, all the asynchronous tasks are taken by the event-loop.


    Benefits of Nodejs Development

    Node.js is one of the unique and fantastic frameworks from other JavaScript frameworks. 

    • Node.js offers amazing performance and it can be used for complex projects.
    • Node.js is the right platform for full-stack JavaScript development.
    • Node.js development is used for the asynchronous non-blocking input/output.
    • Node.js is built on Chrome V8 that converts the JavaScript code into machine code.
    • Node.js provides the architecture containing microservices.
    • Node.js offers ready-to-use tools for building applications with superior development performance.

    Nodejs Use Cases: What is Nodejs used for?

    The usage of the Node.js platform is not only limited to web applications development but also used for enterprise applications including:

    • Microservices
    • Scripting
    • Animations
    • APIs Development
    • Backends and Frontends
    • Servers

    Node.js development is preferred by almost every tech giants from Microsoft, PayPal to Netflix. And the list of these enterprises is growing with time. Let’s explore the types of applications that can be developed using node.js development.

    Real-time Chatbots, Chat-Rooms

    There is no doubt, a huge amount of money is spent by the entrepreneurs on customer care services. To resolve this problem, chatbots are used for better customer experience. Here, the good news is that node.js has all the basic functionalities which are necessary for the development of chatbots. Node.js offers features like server-side events, push notifications, and WebSockets, etc. All these features are required for real-time chatbots. 

    Examples of chatbots in Node.js are drift and sample chatbot developed using Node.js by Facebook.

    Complex SPAs

    The complex SPAs development consists of the allocation of a complete application to a single page application. Here are some examples of complex SPAs are online drawing tools, social networking tools, etc. Node.js app development is considered the best for the asynchronous data flow on the backend. Node.js development eliminates the need for page refreshing as it uses the event loop for simultaneous client requests. Several complex SPAs can be developed using Node.js with other JavaScript frameworks like React, Meteor, Angular, Vue.js, etc.

    Server-side Proxy

    This is a very common problem of third-party proxy services such as Nginx and HAProxy while building complex SPAs. Node.js eradicates this problem also as it can be easily employed as a server-side proxy for collecting data from various third-party resources. Node.js provides the option of proxying the different services with different response times. It is capable of handling a large number of simultaneous requests in a non-blocking manner. Node.js is beneficial for developing applications like Forbes, and BBC, where it requires to load content from third-party domains.

    Data Streaming Apps

    Node.js development has become the number one choice for the development of data streaming applications. The concurrent multi-threading feature allows for bidirectional audio and video transmission. Data streaming is considered a complex process as it requires a continuous data stream. Unlike the traditional development platforms, Node.js doesn’t require HTTP requests and responses for isolated events. It provides an open connection to the stream app’s data from the server to the local system. The Built-in stream modules allow you to transmit a huge amount of data in chunks.

    Rest APIs

    No doubt, the availability of the SOAP(Simple Object Access Protocol) makes the data transferability easy, but it has made the API integration a complex part. The REST APIs are commonly used in the project like enterprise software development. In Node.js development, the REST APIs are developed using Express.js. Moreover, Node.js doesn’t require additional procedures like JASON-to-object and vice-versa. 

    Queued I/O Inputs

    Generally, the application got crashed due to the huge amount of concurrent data which makes the database congested. Moreover, it is expensive to maintain concurrency and queue data because of the data load. But, thanks to the asynchronous nature of the Nodejs development and event-driven Node.js architecture. The most alluring feature of the node.js development is the queuing of data through caching and messaging queuing infrastructure like RabbitMQ, ZeroMQ, etc.


    Microservices is one of the latest and popular development approach followed by Node.js developers. Node.js helps to make the application scalable due to the lightweight nature. Node.js is the best and favorite technology of the developers for building microservices. An example of the microservices is the Netflix application which is splitting their application into smaller services. 

    Command-Line Applications

    Last, but not least application of Node.js is developing the command-line applications. The reason for using the Nodejs development for the command-line applications is that it has an immense number of packages available for all purposes. With the help of Node.js development, it has made the command-line app development is simple, fast, and extremely cost-effective. 

    We have listed some of the outstanding applications that can be built using Node.js development. These applications are useful for the various industries involving media and entertainment, social network, healthcare, travel, banking, education and eLearning, Fintech, eCommerce, etc.

    Final Thoughts

    After reading the whole blog on Nodejs, I think it is no wonder for you to learn why tech giants like Netflix, Uber, LinkedIn, PayPal, etc. trusted the Nodejs development. Node.js is the right platform for developers who wants to have the perfect performance and accuracy of their applications.
