Every web application development company has to be aware of all the details that differ an average web application from an outstanding one.
So what is a web application?
To put it simply, a web app is a dynamic site combined with server-side programming. As a result of that, web apps can interact with the users, connect to back-end databases, and generate results to browsers.
Here are few web application examples: Social Networking, Online Banking, eCommerce, Online Reservations, Interactive Games, Blogs and Online Forums, and many more.
Coding: Web Technologies List
Web development services use two types of coding for web application development:
Client Side Scripting
This type of code is executed or interpreted by browsers and, generally, all site’s visitors can see it by clicking on “View Source” in the view menu.
The most popular Client Side Scripting technologies include:
- HTML (HyperText Markup Language)
- CSS (Cascading Style Sheets)
Server Side Scripting
This type of coding is executed or interpreted by the web server and it is not visible to the general public or the site’s visitors.
The most popular Server Side Scripting technologies include:
- PHP (very common Server Side Scripting language – Linux / Unix based Open Source – free redistribution, usually combines with MySQL database)
- Zend Framework (PHP’s Object Oriented Web Application Framework)
- ASP (Microsoft Web Server (IIS) Scripting language)
- ASP.NET (Microsoft’s Web Application Framework – successor of ASP)
- ColdFusion (Adobe’s Web Application Framework)
- Ruby on Rails (Ruby programming’s Web Application Framework – free redistribution)
- Perl (general-purpose high-level programming language and Server Side Scripting Language – free redistribution – lost its popularity to PHP)
- Python (general-purpose high-level programming language and Server Side Scripting language – free redistribution)
Web Application Architecture and how it supports the Future Growth
A website development company needs to keep in mind that a good web application architecture supports the future growth that comes from enhanced requirements, future interoperability, and increased demand.
The web app architecture defines how an app will function through object-oriented programming. The most important features include:
- Delivering persistent data through HTTP, which can be understood by client-side code and vice-versa
- Ensuring requests contain valid data
- Offering authentication for users
- Limiting what users can see based on permissions
- Creating, updating, and deleting records
Trends in Web Application Architecture
Just like all other trends, the trends in web application architecture evolve with the technology. One of the newest trends worth mentioning is service-oriented architecture.
What makes this trend interesting is the fact that most of the application code exists as services while each of them as its own HTTP API. Thanks to that, one facet of the code can make a request to another part of the code–which may be running on a different server.
One thing to keep in mind is that web app development is often focused on objects that are stored in tables through the SQL database. Every row has its specific record. So when we are talking about relational databases, it all comes down to relations. Simply by listing the row and the column, you can call on records.
Thanks to the two trends mentioned, viewing apps on multiple devices and platforms gets much easier. Even in the cases where the app code remains the same, the application can still be viewed on smaller screens as it is supposed to.
What makes a Good Web Application Architecture
Having a working app is not all it takes. Web development companies know that they also need a good web architecture. Here are some of the things that make the web app architecture a good one:
- Problems are solved consistently and uniformly
- The architecture is as simple as possible
- Supports the latest standards including A/B testing and analytics
- Offers fast response times
- Utilizes security standards to reduce the chance of malicious penetrations
- Does not crash
- Heals itself
- Does not have a single point of failure
- Scales out easily
- Allows for easy creation of known data
- Errors logged in a user-friendly way
- Automated deployments

We have mentioned several web application development tools above but how can you be sure you have chosen the right one for you? First of all, you need to understand the new 2018 frameworks and how they work.
Understanding Web Development Frameworks
In recent years, you might have noticed that there are more and more web development frameworks which are supposed to make the web application development easier and more effective.
The basic purpose of a framework is to use tools and libraries that will help you reach your specific technical goal and make developing in a language of your choice easier. How they tackle the goal you have set – that is what sets them apart and helps you pick the right one.
Now let’s talk some more about specific benefits and advantages that come with using the right web application framework.
Benefits and Advantages
- Program actions and logic are separated from the HTML, CSS and design files. This way, the designers with no programming experience can easily edit the interface and make design changes.
- Builds are based on the module, libraries, and tools. Programmers can share libraries easily while also implementing complex features and functionalities easily and efficiently.
- Producing the best practice coding with consistent logic and coding standards is much easier with this structure. The developers can become familiar with the code in a short time.
Coding guidelines are sets of rules and standards used in web application development. They apply to coding logic, naming conventions, classes and functions, statements, formatting and indentation, file organization, file name, and folder structure and names.
They come with a whole set of benefits including:
- The best environment for multiple programmers to work on a project together
- Great maintainability and version management
- Fantastic readability and understanding of the source code
- Other developers can understand and become familiar with the code easily
Lifecycle Model for Web Application Development
Web development lifecycle is a new methodology for developing web apps. It involves multiple teams engaged in the process with each of them having the possibility to set forth their own style of operating.
There are 2 basic models an application development company could use:
- SDLC (System Development Life Cycle) – web application development process that includes research to identify and define things such as the architectural design and specifications blueprint, programming, testing and bug fixing, information analysis, implementation, and maintenance etc.
- Agile Software / Web Application Development – focuses on the collaboration of people or teams of people involved in the project to provide a better and easier working experience. This method includes research, analysis, programming, design, testing, project management, adaptation, and maintenance.
Web Application Development Process
The following list of procedures and suggested documents provide a good outline for a Web Application Lifecycle and Process:
- Roadmap Document: Defining Web Application, Purpose, Goals, and Direction
- Researching and Defining Audience Scope and Security Documents
- Creating Functional Specifications or Feature Summary Document
- Team Collaboration and Project Management Document
- Technology Selection, Technical Specifications, Illustrative Diagram of Web Application Architecture and Structure, Development Methodology, Versions Control, Backups, Upgrades, Expansion and Growth Planning Document, Server Hardware / Software Selection

6. Location-based services (LBS) will capitalize on GPS.
7. Augmented reality (AR) and utility apps will integrate.
8. Internet-of-Things apps will connect the world.
How to Create Web Application: Tips to Get It Right
If you want to create a successful app on your first try, you need to know exactly what you are doing. Let’s go through the web application development process step by step.
Step 1: Planning
Before you start with all that coding, you need to take a look at the bigger picture and plan everything ahead. You don’t want to write the code over and over again, do you? Ask yourself the most basic questions such as: What is your goal? What is the overall intention? Who will use the app? How to make it as simple as possible?
Once you know the answers to those questions, you can start building your new web app. However, be sure you have really thought it through.
Step 2: Think about the user experience
Don’t get all caught up with the programming right away. Don’t forget that you should spend a lot more time on the research and preparing the design than the programming itself. One of the first things to think about is the user experience. Try to understand the potential user and create a user-friendly design.
Step 3: Write smarter, not more
Every single piece of code you write has to have a purpose. If you write more instead of writing less smartly, you are practically asking for bugs to appear. Every line of code has to either provide a necessary feature or solve a problem.
Step 4: Choose the right framework
There is no need for you to do everything from the scratch by yourself. In fact, whenever possible, you should make things easier for yourself because not only will the app development process be easier and faster, but you will also avoid a lot of bugs on the way.
Choose the right framework for your web application development and built better quality apps in the shorter time period.
Step 5: Don’t over-engineer things
It is great to think about the future, but don’t over-engineer things just because you have an unclear vision of something that might or might not a future user need. Of course, today’s interfaces will eventually become outdated and there will be a moment when you will have to change it, but don’t get all caught up in that just yet.
Expect to make some updated down the road, but for starters, keep things as simple as possible. It will save you a lot of time and trouble and the app will probably turn out better like this either way.
Step 6: Write testable code
Frequent testing is what makes all the difference. If you want to be a serious developer, you have to take testing seriously. However, some code is almost impossible to test due to the way it was written. Think about that when writing your own code.
Step 7: Know what you’re optimizing for
If you are making just a quick prototype of a code, there is no need to spend a lot of time optimizing it for the perfect reliability etc. However, if you are creating a code that is meant to last a while, you should optimize for readability and extensibility. There will be somebody working on the code after you and they need to understand it. Don’t overcomplicate things just for the sake of complicating things. After all, we already talked about the importance to keep things simple and effective.
FAQs about web application development
