A Topology-Oriented Web Application for Regex-Based Text Validation: Design, Implementation, and Comparative Study

The rapid development of web technologies has changed the way interactive applications are created, developed and distributed. This paper presents a new methodology for creating an interactive web application that combines valid regular expressions (regex) in a modern front-end framework with modern design principles. The project uses HTML5, CSS3, JavaScript, as well as libraries such as Bootstrap, Tailwind and GSAP to create an interface that is responsive, animated and user-friendly. The system also presents network topology considerations to help simulate and characterize interactive communication structures from both educational and practical application perspectives. This work is innovative in the way it combines regex-enabled data validation with interactive data visualization in network topology. It combines computer science theory with practice in modern web development. Experimental evidence shows that a dynamic website is more attractive, responsive and interoperable across different browsers than a traditional static website. Overall, the work spans modern web engineering/applications, interactive learning, visualization, and will enable future integration of backend systems and artificial intelligence (AI) enhancements, or further produce progressive web apps (PWA).
