🛠️ Technical Implementation

Project Architecture

The site is built on React 18 with React Router v6 for routing. A component-based approach is used with separation into shared UI components and page modules. Theme state is managed through Context API with preference saved to localStorage.

Theme System

A toggle with three modes is implemented: light, dark, and automatic (based on system settings). The theme is applied instantly without flickering thanks to synchronous reading from localStorage before the first render. All colors are defined through CSS variables for centralized management.

Animations

Framer Motion is used to create smooth animations: fade-in when sections appear, stagger effect for cards, parallax for floating elements in the hero section. Animations are triggered when elements enter the viewport through Intersection Observer.

SEO Optimization

Each page has unique meta tags configured through React Helmet Async. Open Graph and Twitter Card tags are implemented for correct display when sharing. JSON-LD structured markup is added for the browser extension. Sitemap.xml and robots.txt are created.

Performance

Code splitting is applied for lazy loading of pages. Images are optimized and converted to WebP with lazy loading. Fonts are connected with preload for faster rendering. Result — Lighthouse score above 90 across all metrics.

Responsiveness

A mobile-first approach is used with breakpoints: mobile (<640px), tablet (640-1024px), desktop (>1024px). On mobile devices, navigation transforms into a hamburger menu. All interactive elements have touch-friendly sizes (minimum 44px).

Feedback Form

The uninstall page features a form with a survey on uninstall reasons. Data is sent to the server for analysis and product improvement. The form includes validation and loading/success/error states.

Extension Integration

Welcome and uninstall pages are automatically opened by the extension during corresponding events through the chrome.tabs API. URL parameters allow passing the extension version and other data for content personalization.

🛠️ Tech Stack

📊 Key Metrics

• 6 unique pages

🔧 Implementation Features

Animated Counters

Numbers in the statistics section animate from zero to the target value when appearing in the viewport. A library was used for smooth interpolation with an easing function.

Screenshot Carousel

Slider with auto-scroll and manual controls. On mobile — swipe gestures. Lightbox for full-size viewing with keyboard navigation.

Changelog with Filtering

The version list is loaded from a JSON file. Filters by change type are implemented with card appear/disappear animations. The URL updates during filtering to enable sharing.

Smooth Theme Transition

When changing themes, CSS transition is applied to background-color and color with a 300ms duration. The toggle icon smoothly rotates between sun/moon states.
