Dec 1, 2024December 2024 performance-focused sprint for the vtex/faststore repository. Implemented a major overhaul of the section loading strategy to improve perceived performance while maintaining UX across core pages (home, PDP, PLP, login, checkout, account, search, landing, and error pages). Introduced on-demand rendering via RenderSections and adjusted to a simplified loading strategy to balance performance and user experience. Refactored and modernized the filter components to improve mobile performance by replacing monolithic Filter with FilterDesktop and FilterSlider and enabling dynamic imports so JavaScript is loaded only when needed. Exported the useScreenResize hook through the experimental API to enable external stores to subscribe to screen resize events. These changes collectively reduce JavaScript load, improve TTI, and provide clearer API boundaries for future enhancements.
