Tailwind CSS v4 Configuration

This project uses Tailwind CSS v4 with the new CSS-first configuration approach:

• No tailwind.config.js - Configuration is done via CSS @import and @plugin directives
• Entry points:
  • src/app.css - Main Tailwind import with custom design system
  • src/routes/layout.css - Tailwind plugins (@tailwindcss/forms, @tailwindcss/typography)
• Vite plugin: Uses @tailwindcss/vite for seamless integration
• Custom theme: See src/lib/styles/tokens.css for CSS variables

🎨 Customization

Colors

Edit component classes or app.css. Current theme (GitHub Dark):

--bg-primary: #0d1117;
--bg-secondary: #161b22;
--border: #30363d;
--text-main: #c9d1d9;
--accent: #58a6ff;

Add Commands

In src/lib/components/Omnibar.svelte:

if (command.startsWith('npm ')) {}
  const pkg = command.slice(4);
  window.location.href = `https://npmjs.com/package/${pkg}`;
  return;
}

Clock Format

In src/routes/+page.svelte:

<Clock use24Hour={true} showGreeting={false} />

🧩 Architecture

🔧 Services Layer

• topSites.ts - Chrome topSites API wrapper with mock data fallback for development
• storage.ts - Unified storage using chrome.storage.local with localStorage fallback

🎨 Component Design (Svelte 5 Runes)

All components built with Svelte 5's new runes syntax:

• Clock.svelte - Uses $state for reactive time and $effect for interval management
• TopSites.svelte - Pure presentation component with typed $props
• Omnibar.svelte - Command parser with $state for history and input
• Settings.svelte - Modal with two-way binding to settings store
• ViewportLayout.svelte - Responsive grid system using CSS Grid

🔒 Type Safety

// Strict TypeScript configuration
- strictNullChecks: true
- noImplicitAny: true
- No any types allowed
- Interface definitions for all data structures

Example type definitions:

interface Site {
	title: string;
	url: string;
}

interface StorageData {
	settings: {
		use24Hour: boolean;
		showGreeting: boolean;
		githubUsername: string;
		customLinks: string[];
	};
}

🔍 How It Works

Build Pipeline

1. SvelteKit compiles components to vanilla JS
2. Vite bundles assets with code splitting
3. Post-build script fixes inline CSP issues
4. Manifest + icons copied to build/ directory
5. Output is a standard Manifest V3 extension

Performance Optimizations

• ⚡ No Runtime Framework - Svelte compiles to vanilla JS
• 📦 Tree-Shaking - Only imports used icons/components
• 🎯 Code Splitting - Lazy-load optional widgets
• 💾 Local-First - No network calls on initial load
• 🖼️ No Layout Shift - Fixed background color in HTML

🐛 Troubleshooting

Extension doesn't load

# Rebuild and reload
pnpm build
# Then reload extension in chrome://extensions

Top Sites not showing

• Check Chrome permissions in chrome://extensions
• Ensure topSites permission is granted

Build errors

# Clear cache and reinstall
rm -rf node_modules .svelte-kit build
pnpm install
pnpm build

🗺️ Roadmap

• Chrome Web Store release
• Firefox/Edge support
• Custom widget API
• Cloud sync (optional)
• Theme customization UI
