Node.js is the most widely used runtime environment for web application. Let’s find out why?

Node.js allows developers to utilize JavaScript to create command-line tools and server-side scripting, which involves running scripts on the server to generate dynamic web page content before sending the page to the browser user’s web browser. Node.js runs on V8 engine by chrome which enormously fast compare to any other engine. This makes node.js faster and time efficient.

What is Node.js ?

  1. Node is not a language, it’s a runtime environment.
  2. Node.js can connect with databases.
  3. Code and syntax are similar to JavaScript.
  4. Node is an open source, cross platform runtime environment.

Joyent, a cloud computing and hosting solutions provider, supported Node.js as an open-source initiative. The company also invested in a variety of other technologies, including the Ruby on Rails platform, and hosted Twitter and LinkedIn. The latter was also one of the first organizations to adopt Node.js as the backend for its mobile app. Uber, eBay, Walmart, and Netflix, to name a few, were among the first to implement the technology.

It wasn’t until recently that server-side JavaScript with Node.js became widely adopted. According to Google Trends, interest in this technology peaked in 2017 and is still high.

Downloads of Node.js. Long-Term Support and the most recent versions of Node.js for Windows and MacOS are available here. Also, keep in mind that npm comes pre-installed with Node.js. V8 engine. The engine used in Node.js implementation was originally developed for the Chrome benchmarks in V8’s blog. Written in C++, Chrome’s V8 is used to compile functions written in JavaScript into machine code, and it does the job at an impressive speed. Just check performance 

Why Node.js?

  1. Node is mainly used for API.
  2. We can connect same database with web application and mobile application.
  3. Node is superfast with APIs.
  4. Better efficiency and overall developer productivity
  5. Code sharing and reuse
  6. Speed and performance
  7. Easy knowledge sharing within a team
  8. huge number of free tools

Because of its non-blocking input/output and asynchronous request handling, Node.js can handle requests quickly. Synchronous processing assumes that code is performed in a sequential order on the backend. Asynchronous processing allows requests to be handled without the thread being blocked (non-blocking I/O). As a result, it can send a call back when a request is processed and continue delivering requests. This enables Node.js to use single threading, which results in faster response times and parallel processing.

The event-based model is another consideration. Synchronization is quick when both the client and server use the same language, which is especially useful for event-based, real-time systems. Node.js is a popular choice for online games, chats, video conferences, and any solution that requires continually updated data due to its asynchronous, non-blocking, single-threaded nature.

Why you should use Node.js for web application.

  • Real-time applications:

It swiftly develops multi-user real-time web applications for gaming and conversation applications. Because events drive the architecture, the synchronization process is quick and well-organized on both the client and server sides.

  • Data Streaming:

You can get a lot of advantages out of things like file processing when they’re uploaded. It outperforms Node.js and contributes to a reduction in overall processing time. This capability will be useful to anyone working on real-time audio or video encoding.

  • Strong corporate support

Joyent, as previously stated, aided in the development of Node.js. The Node.js Foundation was founded in 2015 to “allow widespread adoption and help speed Node.js development.” IBM, Microsoft, PayPal, Fidelity, and SAP were among the organization’s original members.

The number of companies utilizing Node.js in production is steadily increasing. PayPal, Medium, Trello, Uber, and Zendesk are among the nearly 300 well-known companies on the list.

Few open source projects have ever had such significant backing from the world’s most powerful corporations. And this indicates that Node.js has a lot of promise.

  • Proxy Server:

Because of its attractive characteristics, Node.js is used to proxy numerous services. It arises as a result of disparities in active time. It can process data from a variety of sources. If an organization does not have its own dedicated proxy infrastructure, Node.js can be used as a proxy server.

  • Community Friendly:

Developers delivered by the large open source community that makes the Node.js application popular. So commands or any hesitation can be sorted easily with the help of internet. In a nutshell, npm is a default Node.js package manager that also serves as a marketplace for open source JavaScript utilities, which is critical to the technology’s advancement. The Node.js ecosystem is quite rich, with over 836,000 libraries now available in the npm registry and over 10,000 new ones being uploaded every week. According to the same statistics, npm modules make up 97 percent of modern web applications. And this is proof of its undeniable appeal among programmers.

With such a large number of free tools available in just a few clicks, Node.js has a lot of promise. Simultaneously, open source software is gaining in popularity since it allows you to create new solutions while reducing total magento integration development costs and time to market.

  • Enhances development speed:

It has a low weight and comes with a variety of tools, which helps to speed up development. The npm repository provides numerous libraries and effective solutions to help you produce more value with less work. Your application’s size can be lowered, and the number of defects can be minimized.

  • Easy learning curve:

Sharing a common language has advantages on both the server and client sides. Both sides can be represented by a single team. It requires fewer developers and eliminates the need to switch between back-end and front-end. The advantages of full stack development can be realized when using Node.js for web applications firms. It will increase productivity and the capacity to share or reprocess code, as well as allow for a smooth interchange of knowledge within the team.

  • Useful Single codebase:

Sending and synchronizing data between server-side and client-side coding is simple. It’s a game-changing piece of technology. The developers’ time is saved to a higher extent. With the help of Node.js, developers may write JavaScript server-side and client-side coding. As on both the sides server side and user side we can use one language for coding or functioning. This makes using node.js very convenient compare to other web application.

  • Rich ecosystem:

Because of the large number of open-source technologies available, Node.js’ potential is extended. It reduces the overall development cost as well as the app’s time-to-market. There are a lot of tools in the npm registry, and many of them are updated frequently.

Does Node js have a future in 2022?

Examining the employment market is an excellent way to see if Node.js has a future. What are the current Node job trends? Is there a demand for Node.js developers? What are the qualifications of the candidates?

To begin with, the Node.js employment market plainly demonstrates that Node.js is in high demand. The demand for Node.js developers is roughly twice as large as the supply, according to Hacker Rank data. To make matters worse, the problem is not just one of quality, but also one of quantity. It takes a long time for a Node.js developer to mature, as it is often a technology that is learned after a deep understanding of JavaScript and knowledge of Other technologies, such as PHP and Python, are used to construct the backend. Finding a skilled and suitably experienced Node.js developer nowadays is a lucky break for any company.

Further developments of the Node platform

Node.js began as a solution designed to make JavaScript accessible from the backend. It has matured into a comprehensive platform that provides businesses with a plethora of options for developing innovative, high-performance online apps. The platform’s developers, as well as the users, are constantly adding new features. The thriving community also ensures that all interested parties have access to a wealth of learning resources.

We’ve seen a trend of Node.js alternatives emerge in recent years to give Node a fight for its money. Deno is one of them, a backend platform that leverages Type Script (a superset of JavaScript) as its primary programming language. Deno was created by one of the early Node.js developers, which is quite fascinating.


Node.js is very commonly used runtime environment for web application yet very efficient with its easy command language, used on both server side as well as user side. As it runs on V8 engine by chrome it is very fast with multiple users also.  The overall structure of this model is very efficient compare to other environments, As we can connect this model to an database also this becomes more easier to work on as developer and user. However, while it has some promising results. There appears to be no technology capable of competing with Node when it comes to powering the web with JavaScript/TypeScript at this time.
