Introduction
Nowadays, building a website or web application has become easier than before. With tools like ChatGPT, GitHub Copilot and other AI tools, someone can create a simple website by just typing what they want. This has made development faster and more interesting, especially for beginners.But there is something we should not forget: building an application is not just about making it look good or making the buttons work. There is more to it.This is where software engineering comes in. Software engineering helps developers plan, build, test and maintain applications properly. Without it, we might end up creating applications that look perfect on the outside but have serious problems inside.What is the relevance of software engineering in WebApps?Software engineering is important because it gives developers a proper way of building applications. Instead of just writing code anyhow, developers follow certain steps to make sure the application works as expected.Here are some reasons why it matters1.It helps to reduce errors
When developing a web application, mistakes can happen. Software engineering encourages testing and proper code review, which helps developers find and correct errors before users start experiencing them.

It makes applications more secure Security is one of the most important things in web development. Most web applications handle information like usernames, passwords, emails and sometimes even payment details. Software engineering helps developers put security measures in place to protect this information.
It makes maintenance easier Imagine building a website today and finding out that you need to add new features next month. If the code was not properly arranged, making changes could become very difficult. Software engineering encourages clean and organized code, making future updates easier. 4.It improves user experience A good web application should not only look attractive but should also be easy to use. Software engineering helps developers think about how users will interact with the application and make sure everything works properly. What is Vibe Coding? Vibe coding is a way of developing software where someone uses AI tools to generate code by giving instructions in normal language. Instead of writing everything manually, the person tells the AI what they want, and the AI produces the code. For example, someone can tell an AI tool to create a login page, add a database and make a dashboard. Within a short time, the AI can generate most of the code. Honestly, this is very helpful, especially for students and beginners who are still learning how to code. It saves time and can help people understand new concepts. However, the problem starts when people depend completely on AI without understanding the code it produces. The Demerits and Dangers of Vibe Coding Even though vibe coding has its advantages, it also comes with some risks.
Security problems AI can sometimes generate code that contains security weaknesses. For example, a login system might look like it is working properly but may not have strong protection against unauthorized access. If developers use such code without checking it, hackers might find ways to access private information.
Lack of understandingSome developers simply copy whatever AI generates without understanding how it works. This becomes a problem when something goes wrong because they might not know where to start fixing it.
Poor code quality AI can generate code that works for a short time but is not properly organized. As the application becomes bigger, the code can become difficult to manage and update.
Data loss and privacy issues A poorly developed web application can expose users’ personal information. Imagine using an application to store your information and later discovering that other people can access it because the developer did not put proper security measures in place.This is a serious problem that can affect both users and the organization behind the application.
Too much dependence on AI Another problem is that people may stop learning the actual skills of software development because they depend on AI for almost everything. AI is supposed to assist developers, not completely replace their knowledge and ability to solve problems.What Happens When WebApps Are Built Without Software Engineering Building a web application without following proper software engineering practices can create many problems.For example, imagine a student develops an online school registration system. The system allows students to register, log in and submit their information. Everything seems fine during the demonstration.But what happens when hundreds of students start using it?The system might crash because it was not properly tested. Some students might see information that does not belong to them because access control was not properly implemented. Others might lose their information because there was no proper backup system. This shows that making an application work is not the same as making it reliable and secure.Software engineering helps prevent these kinds of problems through proper planning, testing, documentation, security checks and maintenance.Can AI and Software Engineering Work Together?Yes, and I believe this is actually the best approach. There is nothing wrong with using AI tools during development. In fact, AI can help developers write code faster, find errors, explain difficult concepts and even suggest improvements.However, developers should still understand what they are building.A good developer can use AI to generate code, but should still review that code, test it, check for security problems and make sure it meets the requirements of the project. AI should be treated as an assistant rather than someone who takes full responsibility for the application. Conclusion In conclusion, software engineering is still very relevant in modern web application development. Technology is changing, and AI is making it easier for people to build applications, but that does not mean we should ignore the proper way of developing software.Vibe coding can save time, but depending on it without understanding the code can lead to security problems, poor performance and applications that are difficult to maintain.As students learning software development, I believe we should focus on understanding the basics and learning how to build applications properly. We can use AI to make our work easier, but we should never allow it to do all the thinking for us.At the end of the day, a good web application is not just one that works. It should also be secure, reliable, easy to maintain and useful to the people using it.
