When a company is offering its services to the users which are sometimes counted to millions of them, they have to make sure that their system is perfectly good for all the operations it needs to handle for the users. To fulfill this desire, companies are very careful in picking up the programming language for the backend development. Choosing the right framework is crucial when it comes to developing the software that drives all the user-related services but making that decision is not so easy. Though as per the popular opinion, Node.JS is the perfect choice for the backend, I’m afraid it’s not the only choice for it.
To build fascinating server-side architecture in the business, tons of tools are available and each one has something unique to offer. But if we talk about Node for backend development then it might pique your interest to know that as of today, this programming language empowers more than 100 thousand websites and some of the top online service providers on the internet. So, we decided to find out how this language works well for all the backend developers across the entire globe. And without any further ado, allow me to share why the developers prefer to use Node.JS for backend development services.
What is Node.js?
The advantages of Node.js
Robust technology stack
- better efficiency and overall developer productivity
- code sharing and reuse
- speed and performance
- easy knowledge sharing within a team
- a huge number of free tools
Fast-processing and event-based model
Tests have shown that Node.JS is very fast in terms of performance. The results prove that Node.JS can handle concurrent requests more effectively in comparison to other programming technologies like PHP, JAVA, GO, and more. The reasons behind such amazing results are discussed below:
Node.JS is also capable of processing requests without any kind of delays because it is equipped with non-blocking input/output and asynchronous request handling mode. Pretty cool right? If we are talking in the terms of backend then it is assumed by asynchronous processing that the code is implied in a sequence.
Normally every request holds a thread that makes other requests wait until the previous ones are finished processing. But in the Node.JS backend, every request is processed without blocking any thread using non-blocking I/O asynchronous processing. A callback is pushed when the request is processed while other requests are served continuously. Concurrent processing and short response time have helped Node.JS make the most out of single threading.
Another most important advantage of using Node.JS is its event-based model. When you are using the same language on both the client-side and server-side, the synchronization will take place real fast which is proved to be very helpful for event-based real-time apps. If you are working on any kind of solution that demands constant data up-gradation like chats, video conferences, gaming, and more then the single-threaded, asynchronous and non-blocking nature of Node.JS makes it the ideal choice for you.
Even if you have opted for something else, you can divert back to Node.JS without facing any serious consequences. Many top companies in the world have done it to develop Node.JS applications and have achieved great results. For example, Paypal migrated from Java and noticed a significant decrease of 35% in their app’s response time.
Scalable technology for microservices
You need a lightweight technology tool for microservices architecture and nothing could be a better option than using Node.JS. Martin Fowler and James Lewis describe its architectural style as “an approach to developing a single application as a suite of small services, each running in its process and communicating with lightweight mechanisms, often an HTTP resource API.”
Instead of building a single alleged monolithic core, you can break your app logic into smaller modules and microservices. This will not only lay the groundwork for the future growth of your application but will also provide better flexibility to it. So instead of integrating all the additional features into the basic functionality of web applications, it is much easier to just add more microservices on top of existing ones.
Almost half of the microservice developers build web apps using the Node.JS backend. As the microservices type of architectural style is getting more attention, the companies that use it are experiencing significant growth. Here, each microservice in the application communicates directly with the database using streams that enhance the speed and performance of the app. For instance, let us take an example of Walmart’s shift to Node.JS with microservices architecture, they availed the following benefits –
- Overnight 20 percent conversion growth in general and 98 percent mobile conversion growth
- One hundred percent uptime on Black Friday (handling over 500 million page views)
- Saving up to 40 percent on hardware and 20-50 percent on overall operations
Another interesting success story about how Node.JS outperformed its competition in the terms of performance shines brightly in the case of GoDaddy. While running the SuperBowl ad campaign, the company was able to manage approximately 10000 requests per second without any downtime, and that too using only 10% of their hardware. This all became possible just because of Node.JS.
When you have access to such a huge amount of free tools and resources, the potential to use Node.JS becomes relatively high. Open-source backend technology allows you to create new solutions that can speed up your time-to-market and reduce development costs.
Strong corporate support
Initially, the Node.JS was supported by Joyent but in 2015, a Node.JS foundation was created with the sole aim to “enable widespread adoption and help accelerate the development of Node.js.” It might pique your interest to know that IBM, Microsoft, PayPal, Fidelity, and SAP were among the founding members of this organization.
On the other hand, the companies using Node.Js for web app development are on the rise. Including PayPal, Medium, Trello, Uber, and Zendesk, the number has reached more than three hundred top companies. There are just a few open-source technologies that have got to enjoy such strong support from the world’s leading tech companies.
Seamless JSON support
Why is Node.js good for the backend?
Backend is the most important aspect of any application whether it is a single-page app or a multi-functionality ERP software. Therefore, the developers must pay attention to every little detail and employ the best solutions as well as technology to the ongoing project. Node.JS can work very well with huge chunks of data in real-time. It also allows gathering and displays the data on the dashboards. But you should also note that HTTP requests and responses are large streams of data.
- Node.js backend development is concise because it offers a variety of features that can be impossible to have with an event-based environment.
- Node.js is fast as it stores its data in native JSON.
- It is supported by a large community of developers that are trying hard to improve the technology. Node back end can even perform high-level data streaming. And it doesn’t matter which operating system you are working on because it is suitable for all kinds of platforms.
- NodeJS is non-blocking and supports async functions so it can manage simultaneous tasks. So when the requests are handled in a single thread instead of queuing, this would help you accelerate the server activities.
- You can enhance the performance of the apps built using NodeJS technology. And they are scalable too.
- It is simple to learn and easy to use.
When Node.js Backend is Not the Best Choice
Node.js is not a one-size-fits-all solution. When the load on the CPU tends to grow beyond its capacity, the efficiency will start going downwards. So, if you are required to process a large amount of data on the server-side then you must choose a little more stable and resilient programming language. Sometimes it is noticed that NodeJS apps have failed to manage heavy computing operations, blocking incoming requests and reducing server response speed.
If you are developing a simple CRUD or HTML app that can directly transfer the data from the server then the APIs rendered by the NodeJS technology is unnecessary. Because if you use them, things will only get complicated.
The biggest benefit of an open-source library is that anyone can upload custom features on the internet. The same thing is its downside too as many such donors have limited expertise and are prone to make some serious coding errors that can not only reduce your app’s efficiency but can also doom your time to wearisome bug fixing. So it would be wise to borrow your extensions from some authentic and authoritative sources.
Being one of the open-source frameworks, NodeJS follows an event-based model for app development and full-stack development. Though there are other technologies out there, none has that much speed, scalability, and active community support. So, if you are considering or rethinking your idea about having Node for the back end then I hope that this article on the advantages of using NodeJS might have helped you along the way.
