Node.js App Customisation - How Your Web Application Can Benefit from Node.js

With Node.js you can not only quickly build stable and scalable web applications using modules and packages, but also customising each element with it is easier than with any other backend technology available.

Modern web application development is all about doing things fast. Software engineers can build fully functional products with ready-to-use packages and modules. The most popular technologies with strong global communities, such as the Node.js JavaScript runtime environment, offer a quick solution to almost any problem.

Even if you don't plan it, your app should be ready for customization

However, if your web app gains traction, you can be almost sure that sooner or later you will need to customise it to meet the particular needs of the stakeholders. The good news is that if you choose Node.js as your backend technology any modifications shouldn’t be a problem.

In the long term, it’s a significant advantage. When you plan to create an app, you have to take many stakeholders into consideration: end users (customers), business partners, investors, your own (or your client's) vision, regulators (there’s always another GDPR surprise waiting around the corner), and finally, what the software developers think.

Each of these groups has its impact on the application you are building. Furthermore, each one of them can most likely be divided into subgroups. What’s more, their impact will change with time and the growth of your project.

The dynamic interactions between the stakeholders over time make the application environment a complex system that will evolve unpredictably over time. That is why it is essential for the software you will create to be able to adapt to changes that are impossible to foresee. While your business plan should be flexible, the technical side of your project should adapt to future pivots even more efficiently.

Taking all of the above into consideration, Node.js seems to be the best backend technology choice. First of all, Node.js is modular. The framework doesn't have strict rules for development or a given architecture you have to stick to when planning your web application’s functionalities.

It's so much easier to customise independent modules

Developers can build each module ("node") with a different set of tools (web services, packages, programmes, frameworks, etc.), which makes Node.js conveniently adaptive to change. When you come up with an idea for a functionality, your software engineers can respond by choosing the best solution to build it.  Moreover, they can adjust the way they code to the situation.Modular structure gives you much room to act. That is why you will have no problem making a unique product.

Secondly, Node.js logic is straightforward, event-based, and easy to test. With Node.js not only can you add modules very quickly, but also customise them effortlessly, which is not always true with other popular backend technologies like Ruby on Rails or Python. Here's an example of how quickly and easily you can create a custom Stripe checkout integration with the Node.js Express application framework.

Node.js allows developers to customise the project’s structure so that your application can meet the needs of stakeholders and the technical requirements. Decentralized architecture solves the most significant challenge that customisation brings: software stability. Since you are modifying just a single module, it is much easier to control its interactions with other elements of your app’s environment and the code behind it.

Just remember that customisation is a bit more challenging

There is also one thing you have to keep in mind when customising your application: you will need skilled developers, who understand the functions and code used in the packages they are using. Node.js event-driven programming is so straightforward that even a junior JavaScript developer could quickly bootstrap a simple web application for you using ready-to-use “bricks,” but sustainably customising these elements requires much more expertise.

Still, Node.js has become the most popular programming technology over the last years, and it has the largest community of developers built around it, which makes it the most comfortable backend technology to learn and use. Especially if you need a flexible environment that is easy to customise.
