What is Node.js? The main stages of creating applications using this framework. Which company will help to realize your project in a short time?

How to create an application with Node.js?

Developing applications for mobile gadgets with Node.js is the best choice for growing your business. Applications, unlike websites, are much more convenient because, through them, access to the necessary server is faster. Most large companies, in addition to websites, launch applications to sell their products or services. And applications built with Node.js perform all the tasks. Today we want to tell you more about this framework and discuss the main steps in creating applications.

Purpose of Node.js

This system is used in many areas of business: construction, logistics, services, finance, publishing, and many others. Therefore, the most prominent companies (such as IBM, Microsoft, Netflix, Twitter, YouTube, etc.) could not do without this program. Due to the growth in the volume of information and the size of the user audience, many popular platforms have had to be restructured.

This framework works synchronously with the input/output device while using external data libraries created by other programming languages.

Node.js has an event-driven model, and with a high speed of functionality, it handles enormous volumes of simultaneously active connections, which allows applications to be scalable in real time.

What tasks does Node.js solve?

Before deciding on the use of this system, consider the list of tasks that it can easily cope with:

  • provides rapid development of the platform;
  • solves all the requirements set by the company before development;
  • promotes fast access to the server;
  • provides the ability to process and store a considerable amount of information;
  • the clear structure of the application;
  • there is support for such servers as Google, Apple, and Microsoft;
  • online scaling occurs from within due to changes in the amount of data and users;
  • provides high reliability of the server from external “attacks.”

Given such a set of features of this program, it is so attractive for most companies with a considerable number of tasks necessary for developing and selling their products.

Application creation steps

When developing an application, you must go through several successive stages, which we will discuss in more detail below.

Choose platform type

It is only possible to develop one application that would work on all devices. There are various operating systems for which you need to build a specific application. It is recommended to focus on the Android operating system because it is used in over 70% of all mobile devices.


The application’s relevance is affected by its ” picture ” and the images of its internal menu. The design should be such that most users want to install it on their gadgets. If you are a large company, use your brand in the design elements (emblems, logos, and symbols by the color combination of your company). The more recognizable the “shortcut” of the application, the better.

User comfort

Before starting development, you need to consider the list of the main menu and its subsections. All titles should be clear and concise. Most of the main sections should be accessible in 1-2 clicks. If the user needs to go a long way, this inconvenience will repel the audience and, therefore, will not be in demand.


The most crucial stage of development is the creation of code in Node.js. This code will affect the performance of the application:

  • Loading time;
  • Searching for the required partition;
  • The performance of essential functions;
  • Technical support.

To minimize the load on the platform, the code should be small. And with the help of Node JS Express, you can create its architecture much faster.

Populating the application with data

Although the app is much smaller than the website, it should still contain sufficient information. Content filling (text information, video files, images, etc.) affects the application’s popularity. The better the data, the more it will be used.

The lion’s share of content is contributed at the end of the release, but the main sections should be included initially.


No qualified specialist will launch a website or application without passing a multi-level test. The task of the test is to find (if any) all the shortcomings and errors in the program, which should work smoothly even with a sharp increase in load, before launching it on the network: an increase in processed data, an increase in the number of users, more requests for downloads, and so on.

If the application does not work correctly, the audience refuses to use it. To completely eradicate inaccuracies, the following testing steps are carried out:

  • checking the performance of all components: separately and then together – this is how the code is checked;
  • check by increasing the load – even if the load increases, the platform should work without failures;
  • reliability – to ensure safety from external influences.

When all stages of the test are completed, a list of errors is compiled that are subject to correction. And only after the final adjustment can the application be launched for use.

Product release

The release is in the final stage of development. Depending on the choice of the operating system, the application platform is launched on the App Store or Google Play. Then there is a comprehensive check of the requirements – in social networks, websites, and forums. Having thus passed the real “test,” the application is considered complete.

If you want not to lose your audience of users, then, as necessary, update your application data, this will attract new users and “keep” existing ones. To develop a platform, it is recommended to contact specialists with sufficient experience in this area – creating sites and apps.

SECLgroup, as the best helper in building applications based on Node.js

This team will be able to solve the problems posed to them by the company based on their needs to promote the product. The following indicators will tell a lot about this company:

  • work experience – more than 15 years;
  • cooperation with companies from 24 countries;
  • more than 200 clients;
  • development of platforms for various business areas: medicine, publishing, finance, tourism, trade, media, auto manufacturing, logistics, service sector, construction, education, household appliances, sports, advertising, and many others;
  • over 600 completed projects.

The application developed by SECLgroup will be functional regardless of load surges, easy to use, and high-quality. And the complex tests they conduct are a guarantee of reliability.
