Abstract

The aim of the article is to investigate the factors affecting the performance of Progressive Web Applications (PWAs) on mobile devices. For research purposes, a custom PWA website was created, which served as the primary object of analysis. Various optimization techniques were then applied to the site, including resource minimization, lazy loading, and a distributed content delivery network. The performance analysis of the PWA site was conducted using assessment tools such as PageSpeed Insights, DebugBear, Uptrends, and WebPageTest. The research results were grouped according to several criteria, such as page load time, interactivity, and overall application performance. The obtained results were analyzed after each optimization was implemented. Based on the conducted analysis, conclusions were drawn regarding the impact of the applied optimization techniques on the performance of the PWA. The article emphasizes the importance of continuous optimization and monitoring of applications to ensure high-quality user experiences, as well as presenting an effective alternative method for developing applications for mobile devices.
