Why Node.js is the best choice for back-end development?

Node JS

A brief intro to Node.js

JavaScript is the most widely used programming language for creating online apps. It can be used for both front-end (client-side) and back-end (server-side) development. The truth, however, is that the front-end’s beauty is dependent on the back-end. Node.js comes into play at this point. Due to its extensive capabilities, hiring experienced Node.js developers is the best choice for server-side application development. For server-side programming, Node.js is used by well-known companies such as Uber, PayPal, Netflix, Walmart, Twitter, LinkedIn, and even NASA.

What is Node.js?

Node.js is an open-source application runtime environment that enables the creation of JavaScript-based server-side applications. It’s a lightweight technology that offers rapid development and opens up new possibilities for web development.

Is it a good idea to hire Node.js developers?

Certainly, amongst the popular web application frameworks and programming languages, Node.js is captivating the hearts of not just the developers but also the business owners. Especially when it comes to building enterprise-level, robust data-intensive web applications. By hiring highly talented freelance Node.js developers who take meticulous care of each project, you can guarantee a quality web application development to scale your business.

Additionally, a leading Node.js development company can provide you with the greatest services. The Node.js package management system called npm also has many utilities and is constantly increasing.

We’ve compiled a list of the benefits of Node.js that may assist you in deciding whether to use the technology or not.

  • Real-time applications: Apps that allow two-way communication between clients and servers are known as real-time apps. Using Node.js development services with Web-Sockets makes it simple for developers to create one. Remote Node.js developers make it easier to handle many client requests and allow library code to be shared and reused. The apps receive immediate answers and perform tasks within time constraints. It is ideally suited for real-time communication due to its single-threaded capabilities. It’s the ideal platform for building low-latency apps, thus making it suitable for processing large volumes of brief messages and simplifying app development using
  • Data streaming: Because of its lightweight and rapid processing capabilities, companies like Netflix are looking for full-stack developers who specialize in Node.js to stream data. Users can pipe requests to each other through the streams, which results in data streaming to the endpoint. With I/O bound apps, Node.js manages data streams. The procedure involves uploading files and receiving data in a stream, which are now processed online. This might potentially be used to stream audio or video in real-time. Writable (write data), readable (read data), duplex (write and read data), and transform streams are the four types of streams (convert read to write data, and vice versa).
  • Microservice architecture: An architecture that takes into account each application function and places it in its proper place. If you hire Node.js developers, it will be extremely versatile, and it can be used to create both microservice-based and server-less applications. You may quickly separate your app into its components, group each microservice into a team, and develop one area independently of the others. As a result, the apps become lightweight and stateless, making serverless architecture integration simple.
  • REST APIs: REST is an acronym for Representational State Transfer, which was first used in 2000. It is a web-based architecture that makes use of HTTP protocols. These are required for microservices to function. The best option is to use Node.js development services and Express to create responsive, efficient, and lightweight APIs. When JavaScript is utilized on both the front-end and back-end, the REST API connection is made simple.
  • Single-page applications: Single Page Applications (SPAs) load a single HTML page and dynamically update it when the user interacts with the app. This minimizes response time and makes SPA content appear simple for visitors to engage with. If you hire a Node.js developer, they support server-side rendering, a page can be rendered before it is sent to the browser. SEO optimization, speed, flexibility, decreased loading time, and ease of navigation are just a few of the advantages of SPAs.
  • Hosting deal: The application’s functionality is impacted by the hosting you choose, but there are fewer problems in working with a Node.js back-end developer. The app can practically be hosted anywhere, including web servers and cloud hosting companies. Even corporate behemoths like Google and Amazon have mastered it.
  • Easy installation: Any framework that requires time and effort to install, no matter how feature-rich, defeats the objective of streamlining back-end processes. Developers benefit greatly from the built-in support of the NPM tool, which comes standard with Node.js installation.
  • Highly extensible: Node.js is extremely extensible, which means you may adapt and enhance it to meet your specific needs. Developers can use JSON to allow data to be sent between the server and the client. It also includes features like built-in APIs for creating TCP, HTTP, and DNS servers.
  • Rich ecosystem: NPM, open-source package management for Node.js, contains a number of tools and packages that aid developers in developing online applications. It functions as a Node.js marketplace where app developers may find answers to their problems. The NPM main registry has over 1.3 million packages, which is growing every day, making Node.js development services one of the most diverse ecosystems. Developers can use any of the NPM registry’s available packages or tools to meet their app’s needs. For example, you can utilize the passport package if you wish to add authentication. You can use the Express, Koa, and Hapi packages if you need to create an API.


As we highlighted in the blog, there are numerous reasons to support the efficiency of Node.js for back-end development. It may be used to build single-page apps, APIs, dashboards, and proxy deployments. After all, with its great community, single-thread event-driven paradigm, and easy development process, this JavaScript runtime provides an amazing user experience. Furthermore, the technology is rapidly evolving, with no signs of slowing down any time soon. As a result, we can conclude that Node.js full-stack developers are the ideal choice for developing the back-end of various products. However, be certain that your tool or language of choice suits your business needs.
