Web application development

by Carter Toni

Web applications have become so popular and widely used that the average user sometimes can’t even notice the difference between a website and a web application. Web apps interact with a mobile browser, gradually replacing desktop solutions for the education, media, and entertainment sectors. Now companies make use of web applications for meeting the requirements of businesses, e-commerce and startups.

What is a web application? 

Web app – is a platform with a client-server architecture of two levels. The client interacts with the user interface (UI/UX) via the web browser pages. All data is stored on the server. The process of information exchange takes place over the network using HTTP/HTTPS protocols.

When building web applications, programmers create a complex architecture. After the authentication, users interact with this architecture. To make it possible such programming technologies as JavaScript, HTML5, CSS are used.

https://devoxsoftware.com/services/web-app-development-services/ is always devoted to solving a specific problem, usually one. Web applications must quickly adjust to changes and new tendencies. The simpler and faster the reaction time of the web application is, the more viable it is believed to be.

How to develop a web application

There are numerous ways to build a web application. In this article we will talk about the most popular one. It lies in creating the front-end as a single-page app. In this model the contact is established through the REST API. If you want to build a web application using this approach you have to go through the following 7 steps.

1. Work out the backend business logic

Basically, you have two options here. You can implement a monolithic logic by grouping the backend business logic into one service or create separate microservices for each component. The chosen strategy should depend on the size of the project. For small projects opt for monolithic backend business logic, for large ones choose the second option.

2. Decide on the programming language

It is essential to take into account all your business purposes while choosing the programming language for building web application. You can hire dedicated Java developer to meet even the most sophisticated requirements. However, if you don’t view the performance of future web applications as the most important aspect, you can opt for Python that offers Flask and Django frameworks. Ruby is another beneficial option since it provides Ruby on Rails and Grape frameworks. Gelang is the best programming language if the speed of the future application is your main priority. It offers such frameworks as Gingonic, Beego, and Revel.

Anyway, you can opt from a variety of programming languages. The main thing you should remember is to choose the one you really know.

3. Work out the business logic

MVC is the main thing you should focus on. Then, when the business logic becomes more sophisticated, make use of the presenter and interactor. The first one acts as callbacks from internal levels. The task of the interactor is to transform data from the web application and move presenters to the screen using a View. Interactors in fact represent the web application business logic.

4. QA testing of the backend

Testing is essential for understanding whether the business logic of your web application is working correctly. You can apply automated checking of libraries, modules, UI/UX and API compliance.It is a great idea to create a roadmap for the platform. In such a way you will be able to manage all types of testing.

5. Swagger support

Swagger is a set of tools that allow to describe API. It gives users and machines a better understanding of REST API capabilities without having direct access to the code. With Swagger, you can quickly create documentation and send it to other developers or clients.

6. The frontend business logic

It is difficult to work with the frontend business logic due to the fact that there are currently numerous frameworks available. Nowadays, the developers frequently opt for React and Angular. Both of them have their pros and cons. Anyway, I recommend you to choose the React frontend because it is simpler and more flexible.

7. The analysis of web app quality

Now your app is ready. However, there are still a few things for you to remember. Firstly, you need to understand how well the application is implemented and how well it will work. You can use Lighthouse to make the analysis easier. It conducts a system audit of the performance and availability of a web application for the understanding of the average user.

All in all, you should take all these stages seriously and pay attention to the details. Otherwise, you won’t develop a powerful and appealing web application.
