PROGRESSIVE WEB APPLICATION DEVELOPMENT TECHNOLOGIES: ANALYZING AND EVALUATING EFFECTIVENESS

The article examines the key components of Progressive Web Apps (PWA), including Service Workers, Web App Manifest, and HTTPS, which ensure performance, security, and usability. Particular attention is given to their role in optimizing the user experience and reducing the costs of application development and maintenance. The research methodology includes an analytical review of modern technologies, a comparative analysis of architectural solutions, and experimental testing that compared PWA and native applications. The experiment evaluated parameters such as loading speed, device resource consumption, ease of installation and updating, and offline functionality. Both objective metrics and subjective data reflecting user satisfaction were used in the analysis. The results demonstrated that PWA enables quick installation, efficient resource usage, and a high level of convenience comparable to native solutions. At the same time, the offline functionality of PWA slightly lags behind traditional applications. Modern development tools such as Google Lighthouse and Workbox, which contribute to optimizing PWA performance, are also discussed separately. These tools allow for the automation of testing processes, caching strategies configuration, and overall application performance improvement, significantly simplifying the creation and maintenance of web solutions. The findings indicate that the adoption of these technologies can profoundly influence the future of digital development due to their accessibility, cost efficiency, and high-quality user interaction.
