Key Trends in Web App Development for 2024

There is no doubt that each year in web development is different, bringing new trends and solutions, depending on the security needs, the expectations of the users, and the overall advancement in technology. In 2024, web applications will continue to improve in terms of functionality and performance, as accessibility and sustainability of development become more critical. In addition to modifying how web applications are designed, secured, and developed, artificial intelligence also plays a part in this process. For 2024, what are the key trends in web application development?

Use of Progressive Web Apps

Web app developers have been working hard to create a solution that combines the features of websites and mobile applications, resulting in the emergence of Progressive Web Apps (PWAs). PWAs offer the benefit of swift and reliable operation, even in areas with poor network conditions or no Internet Access. Moreover, users do not need to download PWAs from app stores as they can be added to the home screen. These features contribute significantly to the increase in user engagement and satisfaction.

PWAs are designed to load quickly and operate smoothly, which can enhance conversion rates. With background updates, users can rest assured that they are always using the latest version. Communication with PWAs is safe, as they are connected via HTTPS, ensuring the protection of the user’s data.

PWAs are mostly popular in e-commerce, media and publications, and in travel and tourism, where the fastest possible page loading speed is valued for higher conversion rates or sales growth.

High cybersecurity level

With the increasing complexity of web applications, it is essential to ensure a high level of cybersecurity. To achieve this, advanced security strategies such as security audits, end-to-end encryption, or multi-factor authentication are required. However, advancements in technology have also contributed to the growing number of cyber threats.

One of the most common measures used for protecting web applications is data encryption, using protocols such as HTTPS. Filters, input data validation, and secure coding practices can provide additional protection against attacks such as Cross-Site Scripting (XSS), SQL Injection, and Cross-Site Request Forgery (CSRF).

Two-factor authentication has become more prevalent, which limits unauthorised access to data. Additionally, regular maintenance of software, including servers, databases, and other components, helps keep them safe from malicious behaviour. Applications must also be secured against Distributed Denial of Service (DDoS) attacks, which occur when the server is blocked by excessive traffic.

Modern WebAssembly code

In response to the current demand, a modern binary code standard for executable web programs has been created, called WebAssembly (Wasm). It allows code written in programming languages like C, C++, Rust, and even Go to be executed directly in web browsers. This code has revolutionized performance, making it comparable to native code, and has opened the door to the creation of more complex applications.

Wasm applications offer extra protection thanks to their sandbox operation and can be easily used on any platform or browser without the need for code changes. Additionally, they can be used together with existing web technologies.

Serverless Computing

The greatest revolution in web application design, development, and management is possible due to serverless computing, or architecture.

Never before have developers received the possibility of infrastructure handling by cloud service providers, letting them focus on code and business logic. It can greatly save costs, and increase efficiency and flexibility of application development.

Developers can adjust the architecture to the current needs, and scale it. The improved efficiency reduces the costs but also by the payment only for the resources used. The product development time is shortened with the highest security level provided by the cloud service providers.
