10 Benefits of Node.js for Backend Development Services

Node.js is one of the most popular programming languages today—and it’s not just because of JavaScript. Node.js has changed the game in backend development, providing developers with a powerful tool that can be used to build everything from data-heavy enterprise applications to user-friendly web apps and more. Here are 10 reasons why Node.js has become the best backend development framework on the market today.

10 Reasons Node.js is the best Backend Development Framework

1. First reason to choose Node

The first reason to use Node.js for backend development services is that it allows you to develop fast, efficient and highly scalable applications. Since it uses JavaScript as its base language, most of your developers will already be familiar with writing code in it which makes things much easier for them. It also lets you benefit from using NPM modules that can streamline development work immensely and help increase productivity for both new and experienced developers.

2. Performance and Scalability

Although most developers would balk at creating something that runs slow or not scaling to meet demand, sometimes applications run into trouble early on because of poor planning. A great deal of software optimization can be done at build time, so it’s essential to have someone with a strong understanding of how a server works and what can be improved upon while your app is still under development and easily altered before going live.

Once you go live, it’s much harder to make sweeping changes or add in new features. That’s why finding an experienced development company is key—you need someone who understands that scalability doesn’t happen overnight; it takes months of work to create a stable architecture that won’t buckle when everything gets turned up to eleven.

3. Open Source Community

Although most businesses are used to open source software, thanks to Linux and Apache, it can be hard for them to understand why we use open source on our servers. Because of that, one of my favorite reasons I’ve found (and one which I think resonates with business owners) is you don’t have to reinvent everything yourself.

The reality is, you’re in a constantly changing industry and even if you wanted to create your own framework from scratch – it would be tough given how rapidly-moving software development has become. Instead of spending time and effort re-creating something you have already created in Node.js, just modify the old module to fit your needs.

4. Single Threaded, no blocking I/O

Unlike other servers, Node doesn’t have to spin up a new thread or process for each request, which means that it doesn’t get blocked while waiting for disk or network I/O requests to finish before being able to service another request. Instead, code execution flow continues and responses are streamed as fast as possible.

In fact, web browsers are single-threaded too: JavaScript event handlers run on different threads than the ones they were triggered from! This design pattern makes efficient use of limited resources and frees you from worrying about deadlocking your server if several requests depend on each other (and don’t use proper concurrency mechanisms).

5. JavaScript — it’s everywhere!

JavaScript is one of those languages that, over time, everyone is going to need to learn or use in their day-to-day job. JavaScript developers are valued across a wide range of industries and it’s not just limited to front-end development anymore either; there are multiple companies (both large and small) who will now hire exclusively JavaScript developers on their backend team as well.

6. Well documented libraries and frameworks

There are quite a few JavaScript frameworks for building applications, and it can be tough to decide which one to use. Most don’t have clearly documented APIs, making it difficult to build something from scratch without consulting external sources or getting in touch with developers who’ve already worked on a similar project.

With Node.js, you don’t have to worry about spending hours—or days—on research: It has well-documented libraries and frameworks like Express, Koa and LoopBack that are ready for your business needs.

7. Expressive code with dynamic typing

When you develop your application, you have to constantly write code and rewrite it over and over again. JavaScript is one of those languages that can be both dynamic and expressive depending on what kind of code you are using in it. The important thing about having an expressive language is that it makes writing code easier for developers because they don’t need to spend a lot of time learning new syntaxes and semantics, so they can focus more on getting their work done faster.

8. Large number of tutorials, modules and books available

JavaScript, in general, enjoys a very large community of developers who are eager to share their experience and help others with problems they face along the way. With such a large pool of talent, it’s easy to find resources on how to do almost anything you want in JavaScript.

It can be difficult, at times, to make sense of it all; but there’s no shortage of information available when you need it. A quick Google search will usually get you what you need and if not then usually a simple forum search will produce results that point you in your desired direction.

9. Memory Efficiency — there is no Garbage Collector

Your server can handle more requests if you don’t have to worry about freeing up memory in between requests. Using less memory means using fewer resources, which in turn leads to a lower operational cost and longer-lasting hardware components.

It also makes your app more scalable because it can support more simultaneous users and doesn’t need as many resources to do so. This is great for applications that process high volumes of data or traffic, such as chats, web applications, push notifications etc…

10. Seamless deployment with Docker

Developing on a local machine and deploying your code to production instantly in just one command makes it easier to understand what works locally and what doesn’t work in production, while making deployments much less risky.

The idea of developing locally and deploying on a scalable cluster that provides high availability can be very attractive for developers who want to focus on coding rather than operations. Having said that, if your deployment strategy relies solely on Docker, you will miss out on many of its benefits since running containers will still require additional operational attention (like pulling images from a registry).

Running containers securely takes time and resources; as a result, using Docker alone might not be enough unless you have an internal team dedicated to container management or take advantage of specialized solutions such as Kubernetes.

Conclusion

No programming language is perfect and although a lot of people don’t like Javascript, it can still be used to develop a scalable, fast, efficient and feature-rich backend system that can do exactly what you want it to. Whether you’re building a website or developing an API, there are thousands of modules and frameworks available for any kind of functionality you might need, which makes it really easy to get started quickly with your own project even if you’re new to Javascript development. You should hire Node.js developers having rich expertise on all these modules and functionalities.
