A complete guide to Web Application Development

Unlimited businesses are taking advantage of businesses for their growth and development. The Internet’s boundless potential has opened the door to reaching a large number of targeted audiences by investing minimal price. The Internet is best for businesses to reach the target market and increase engagement efficiently. However, the effect of all the activities businesses perform to increase traffic can become effective only if the user activities are captured, and all the important information gets stored so that users can see the visible results on their next visit.

Web applications are developed by integrating both server-side and client-side scripts. To store the user information and manage it, a server-side script is used, written in programming languages such as PHP, ASP, etc. On the other hand, a client-side script such as JavaScript or HTML is used to show the user’s analyzed information. In other words, web applications create a communication channel between the company and its users. The interaction is established through online forms, shopping carts, feedback forms, content management systems, etc.


Web applications have changed the way we looked at word applications. Earlier applications are only relatable to mobile. But there is still a lot of confusion among users about what exactly web applications are. To put it in simpler terms, a web application is a client-server application accessible through a web browser interface. Unlike mobile applications, a web application doesn’t require it to be downloaded to the device you are using.  

The Web application can be accessed through any kind of device which has a web browser. It is said to be a client-server application as both play a major role. The client requests a service, and the server initiates the request. Basically, a web application is a computer program that processes client requests through a web server.

Some of the best examples of web applications are WhatsApp web, online retail sales, shopping carts, online forms, online games, online photo editing tools, etc. Web applications can be categorized into five categories, which are static, dynamic, online shopping stores, web portals, and animated apps. We are going to study them in detail further.

The development of a web application is not a road of roses. However, if you follow the right path, then you might end up making the best web application that you had wished for. So here are the 10 points which will help you out throughout your web application development process.

  1.  Mining the Ideas: The first milestone of starting any kind of project is the idea. You know the problem, and all you need to do is sit with your team and brainstorm ideas for the best-fit solutions. Don’t forget to do thorough market research to be aware of already existing web applications in the market, similar to yours.
  2. Understanding the functionalities: Now when you are aware of the application you want to build, the next thing is defining the functionality. Don’t overfill your application with unwanted features but focus on the part that solves the problem for developing the web application.
  3. Designing the application: The next step is to picture the application. Yes, your application must look beautiful. It should have a great UI and UX to find it interesting to use the application. Also, the application’s navigation should be clear so that users can easily explore the application without unwanted delay. In short, your application should be easy to navigate, interactive, and interesting for the user.
  4. Wireframing the application: The next step is to create application wireframes. Wireframes bear the kind of blueprints which behave like the prototype of the final product. Make wireframes for every step, starting from the application launch to the last page. Here think like a user to understand the application step by step and make no mistakes in the navigation.
  5. Testing Wireframes: Test your wireframes to get a validation that you are on the right track to developing a fully functional web application.
  6. Creating application database: Every application has a database that stores user information at the back-end. Therefore you should start making your application database. Your database should be clear regarding segregating the data, primary key, secondary key, connections, etc. Ensuring the security of the database is also vital for a successful web application.
  7. Front-end and Back-end: Build the front-end and back-end of your application. The front end is visible to the user, so it should be interactive and user-friendly. Whereas the back-end is not visible to the user but plays an important role in the application’s smooth functioning.
  8. Testing the application: Test your web application for several inputs. 
  9. Get application hosting: Now it’s time to launch your web application, so you need a hosting provider. Look for a trusted server and make sure that your application doesn’t get crashed while running.
  10. Launch the application: All set to go! Yes, now, all you need to do is wait for your users to use the application in a real-world scenario.


Web applications are often confused with websites. Here are a few points to understand the difference between a web application and a website.

how does a web application work?

The web application code is written in the programming languages supported by the browser, namely JavaScript, Hypertext markup language, etc. The reason behind this is that the browser-supported languages are dependent on the web browser to execute the web application. Web applications can be dynamic and static. Dynamic web applications are executed on the server-side while static web applications can run without a server.

The working of a web application is simple as it is developed to interact with the client. To handle requests from the client, a web server is required, and to process the result of the client request, an application server is needed. The technologies which can be listed under the application server are ASP.elnet, cold fusion, PHP, JavaScript, etc. To understand the working of a web application, we need to go through the points below.

  1. Consider yourself a user who is using a web application. When you click a button on the web application such as login, a request is triggered to the web server. The request is sent through the Internet or the user interface of the web app.
  2. The user request will be transferred to the web application server. For example, the login requests will be sent to the back-end database, which will be processed further.
  3. The web application server will process the request by looking at the database and matching the user login requirements. After verifying the user data, the application server will process the data to the web server.
  4. When the webserver gets the required information, it will display the result of the user request on the application screen. For example, the login requests will be verified, and the result will be login successful.


There are ample programming languages available, namely C, C++, JAVA, PHP, ASP, PYTHON, etc. However, it might be difficult to determine which language can be the best fit for your web application. Some of the best programming languages for web application development are:

  2. PHP
  3. Python
  4. ASP
  5. C
  6. Cascading style sheets (CSS)
  7. HTML

 These are the few programming languages that are preferred by the developers for the development of web applications. However, you can still use the language which you are more comfortable with as, in the end, it all depends on how efficient your web application turns out to be as an end product.

A web application is a client-server application program, as mentioned earlier. The architecture of a web application consists of a framework that shows interconnected relationships between the application’s components, namely the user interface, Web server, and database. In simple terms of application, architecture is a system that is developed to establish the connection between client, server, and database.

The web app’s working begins when we click on the URL, and the web browser looks for the URL on the internet network. The server associated with the URL will communicate with the browser to display the web application page. After this, the interaction begins between the client and the server. It takes very less processing time so that the web application can connect with the user without losing the user’s interest.

The quick response time of a web application depends on several factors, including web application content, internet speed, and the Web application code. Therefore we can see that the architecture of a web application consists of everything from the web server to the device speed on which the application is operated.

The web application components can be categorized as UI components and structural components.

  • The web application’s UI components are referred to as the elements that are visible to the user on their screen. These components can be a dashboard, user history, configuration settings, notifications, navigational panels, etc. The user interface components are not directly related to the application functionality but help users interact with the web app.
  • The web application’s structural components are those components that are responsible for the functioning of the application. These are a client-server, web server, and database. All these structural components are coded through programming languages.


A web application framework is a complete structure on which the web application is dependent. It consists of a set of libraries, tools, and technologies that help develop a web application. Building a framework for a web application requires strong programming expertise as a single wrong line of code can completely change the functionality or bring run-time errors. A framework is designed from scratch, which means there are no boundaries in the development process.

As discussed before, applications can be of five types. Let’s discuss the categories of web applications in depth.

  • Static Web Application

Any web application that the end-user can use directly using a browser without the need for server-side alterations is known as a static web application. In simple terms, non-movable web applications are known as static. For example, online portfolios or digitally related resumes are examples of static web apps.

  • Dynamic Web Application

Dynamic web applications are those applications that do have room for databases, online forms, etc. Content editing is easier with dynamic web applications; however, back-end programming can be difficult while developing a dynamic web application.

  • Online Shopping Web Applications

Online shopping web applications are basically infamous web apps where payment gateways are integrated, and users can interact with the application by adding or removing card items. Examples of online shopping web applications can be Myntra web apps.

  • Web Portal-Based App

A web portal-based application is an application where all the pages are interlinked with the application’s homepage. In this type of application, chat, emails, forums, browsers, and everything is a web page. For example, WhatsApp web.

  • Animated Web Applications

Animated web applications use animation with the help of flash technology. For example, web applications with animated map views can be categorized as animated web applications.

Web application development is one of the emerging fields nowadays as it interacts with users better. A web application development may not require a web application framework; however, the development process can be more effective with a web application framework.
