Rebuild portfolio site with Nuxt 3, Tailwind CSS, Three.js, and FontAwesome

[Copilot]

Complete rewrite from vanilla HTML/CSS/JS to modern Vue stack per user requirements for simpler code with enhanced visual effects.

Architecture

• Nuxt 3: Auto-imports, file-based routing, static generation
• Tailwind CSS: Utility-first styling, zero custom CSS files
• Three.js: 1500-particle interactive 3D background
• FontAwesome: Icon library (brands + solid)

Components

Core Layout

• ThreeBackground.vue: Mouse-reactive particle system with proper cleanup
• AppHeader.vue: Glassmorphic nav with mobile menu
• HeroSection.vue: Glitch text effect + typewriter animation loop + floating code symbols
• SkillsSection.vue: Intersection observer-triggered progress animations (percentages removed)
• AboutSection.vue: Stats grid with hover states + vibecode mention
• ProjectsSection.vue: Project cards with gradient overlays
• AppFooter.vue: Social links with icon integration
• DiscordModal.vue: Custom modal for Discord with username display and copy functionality

Data Flow

// composables/usePortfolioData.ts
export const usePortfolioData = () => {
  const data = useState('portfolioData', () => null)
  const projects = useState('projects', () => null)
  
  const fetchData = async () => {
    if (!data.value) data.value = await $fetch('/data.json')
    if (!projects.value) projects.value = await $fetch('/projects.json')
  }
  
  return { data, projects, fetchData }
}

Visual Effects

• Animated particle field with mouse parallax
• CSS glitch effect with clip-path animations
• Typewriter cycling through role titles
• Backdrop blur + gradient borders throughout
• Animated skill bars (no percentage numbers)
• Floating code symbols (e.g., { }, < >, [ ], =>) instead of generic circles
• Smooth scroll + back-to-top button

Contact Integration

• Discord Modal: Replaced Threads with Discord featuring:
  • Click-to-open modal with username fixeq.dev
  • Copy-to-clipboard functionality
  • Direct link to Discord profile
  • Glassmorphic design matching site aesthetic

About Section

• Mentions vibecode approach: AI-assisted coding with good vibes ✨🤖
• Highlights partial code generation with AI tools

Build Output

• Static site → .output/public
• GitHub Actions workflow updated for npm/Node
• Tailwind content paths configured for proper purging
• Memory leaks fixed (event listeners, setInterval cleanup)

Code Reduction

Before: 10+ CSS files, multiple JS modules, manual DOM manipulation
After: 8 SFC components, composable data layer, declarative templates

Security

CodeQL scan: 0 vulnerabilities

@copilot Zastąp te Floating elements na Hero czymś innym, usuń procenty tam gdzie są języki programowania i frameworki itp. i napisz że częściowo też vibecoduje
Co do kontaktu zastąp Threads discordem, że po kliknięciu otwiera się popup z username moim (fixeq.dev) albo przycisk do profilu na discordzie >>> https://discord.com/users/853621876551188490\

Missing keyboard accessibility for the mobile menu button. The button should be accessible via keyboard navigation and should toggle the menu on Enter/Space key press. While the click handler will work for keyboard users due to button semantics, screen readers would benefit from aria attributes.

Add accessibility attributes:

<button 
  @click="mobileMenuOpen = !mobileMenuOpen" 
  class="md:hidden text-gray-300 hover:text-primary"
  :aria-expanded="mobileMenuOpen"
  aria-label="Toggle mobile menu">

Suggested change

	<button @click="mobileMenuOpen = !mobileMenuOpen" class="md:hidden text-gray-300 hover:text-primary">
	<button
	@click="mobileMenuOpen = !mobileMenuOpen"
	class="md:hidden text-gray-300 hover:text-primary"
	:aria-expanded="mobileMenuOpen"
	aria-label="Toggle mobile menu"
	>

The animation relies on randomly generated positions and durations for code symbols. On each render, these values will be recalculated, causing the symbols to jump positions.

The random values should be computed once and stored:

const codeSymbols = ref([
  '{ }', '< >', '[ ]', '( )', '/>', '=>', '...', '&&', '||', '??', '</>'
].map(symbol => ({
  text: symbol,
  left: Math.random() * 100,
  top: Math.random() * 100,
  delay: Math.random() * 5,
  duration: Math.random() * 15 + 10
})))

Then in the template:

<div v-for="(symbol, i) in codeSymbols" :key="i" 
     class="..."
     :style="{
       left: `${symbol.left}%`,
       top: `${symbol.top}%`,
       animationDelay: `${symbol.delay}s`,
       animationDuration: `${symbol.duration}s`
     }">
  {{ symbol.text }}
</div>

Missing focus trap in modal. When the modal is open, keyboard users can still tab to elements behind the modal, which violates accessibility best practices. The modal should trap focus within itself and return focus to the triggering element when closed.

Consider using Vue's focus management or a library like focus-trap to ensure keyboard navigation is contained within the modal when open.

[Copilot]

The modal backdrop should close on Escape key press for better user experience. Currently, users can only close the modal by clicking the X button or clicking outside.

Add keyboard event handler:

<script setup>
// ... existing code

onMounted(() => {
  const handleEscape = (e) => {
    if (e.key === 'Escape' && props.isOpen) {
      closeModal()
    }
  }
  window.addEventListener('keydown', handleEscape)
  
  onUnmounted(() => {
    window.removeEventListener('keydown', handleEscape)
  })
})
</script>

Suggested change

	}
	}
	import { onMounted, onUnmounted } from 'vue'
	onMounted(() => {
	const handleEscape = (e) => {
	if (e.key === 'Escape' && props.isOpen) {
	closeModal()
	}
	}
	window.addEventListener('keydown', handleEscape)
	onUnmounted(() => {
	window.removeEventListener('keydown', handleEscape)
	})
	})

[Copilot]

The modal lacks ARIA attributes for proper screen reader support. Screen readers won't announce this as a dialog or communicate its purpose.

Add appropriate ARIA attributes:

<div 
  v-if="isOpen" 
  @click="closeModal" 
  class="fixed inset-0 z-[100] flex items-center justify-center bg-black/70 backdrop-blur-sm"
  role="dialog"
  aria-modal="true"
  aria-labelledby="discord-modal-title">
  <div @click.stop class="...">
    <h3 id="discord-modal-title" class="text-2xl font-bold text-white flex items-center gap-2">

The @vueuse/core dependency is declared but never used anywhere in the codebase. This adds unnecessary weight to the bundle and increases installation time.

Remove this unused dependency from package.json.

Suggested change

"@vueuse/core": "^14.1.0",

[nitpick] Using @click.stop on the modal content prevents event propagation, but the modal backdrop click handler relies on clicks reaching the outer div. While this works as intended, it's better to explicitly check the event target to avoid potential issues and make the intent clearer:

<div v-if="isOpen" @click="handleBackdropClick" class="...">
  <div class="...">

const handleBackdropClick = (e) => {
  if (e.target === e.currentTarget) {
    closeModal()
  }
}

[Copilot]

Duplicate onUnmounted hook registration. Vue components should only have one onUnmounted hook per component. The second one (lines 112-119) will override or conflict with the first one (lines 106-109).

Consolidate all cleanup logic into a single onUnmounted hook outside of onMounted.

[Copilot]

Memory leak: The IntersectionObserver is never disconnected when the component unmounts. This will keep references to DOM elements and prevent garbage collection.

Add cleanup in onUnmounted:

let observer = null

onMounted(() => {
  observer = new IntersectionObserver((entries) => {
    // ... existing logic
  }, { threshold: 0.2 })
  
  const section = document.getElementById('skills')
  if (section) observer.observe(section)
})

onUnmounted(() => {
  if (observer) {
    observer.disconnect()
  }
  // ... existing cleanup
})

[Copilot]

The displayedLevels reactive state is defined but never used in the template. The animation logic references it but the template only uses tech.level directly in the style binding. This appears to be leftover code from a previous implementation where percentages were displayed.

Either remove the unused displayedLevels state and animateLevels function, or update the template to use the animated values.
