Today’s Focus: Performance Improvements Based on Lighthouse Audit
Following feedback from Lighthouse, I tackled several areas to improve performance, accessibility, and overall user experience.
Button Component Unification
To reduce redundancy and ensure consistent behavior and styling, I consolidated button components into a single shared version.
This simplifies the codebase and helps enforce a consistent UI across the app.
Replacing Hero Video with Preloaded Image
The hero section previously used a video background, which delayed the First Contentful Paint (FCP).
To improve load times, I replaced the video with a preloaded static image as a placeholder.
This allows users to see something immediately while heavier content loads in the background.
JS-to-CSS Gallery Refactor
I replaced the JavaScript-based gallery implementation with a pure CSS version.
This not only reduces bundle size but also improves performance and maintainability.
Tomorrow’s Plan: Continue Optimization
I’ll continue addressing Lighthouse’s suggestions and explore additional enhancements to reduce layout shifts, improve asset delivery, and optimize image handling.
Performance tuning is an ongoing process — every millisecond counts when it comes to user experience.
