Abstract: Modern web applications demand high performance, scalability, and long-term sustainability to meet the expectations of increasingly global and resource-constrained environments. Next-generation frontend architectures have evolved beyond traditional monolithic designs to incorporate modular, component-driven, and distributed approaches that enhance development efficiency and user experience. This paper explores emerging frontend architectural paradigms—such as micro-frontends, server-side rendering, static site generation, and edge-based delivery—that enable faster load times, improved scalability, and optimized resource utilization. Additionally, it examines the integration of modern frameworks, performance optimization strategies, and sustainable design principles that reduce computational overhead and energy consumption. By analyzing architectural patterns, tooling ecosystems, and deployment strategies, this study highlights how next-generation frontend systems can balance speed, maintainability, and environmental considerations. The findings provide insights for developers and organizations seeking to design resilient, high-performance web interfaces capable of supporting large-scale applications while promoting sustainable computing practices.
