State Management

Zustand Store (usePersonalListStore)

interface PersonalListState {
  items: PersonalListItem[]           // Array of added items
  markdown: string                     // Generated markdown
  isEditorOpen: boolean               // Sliding panel state
  activeView: 'editor' | 'preview' | 'split'

  addItem: (item) => void
  removeItem: (id) => void
  updateItem: (id, updates) => void
  setMarkdown: (markdown) => void
  toggleEditor: () => void
  openEditor: () => void
  closeEditor: () => void
  setActiveView: (view) => void
  clearList: () => void
  importList: (items) => void
  exportList: () => PersonalListItem[]
  generateMarkdown: () => string
}

Item Structure:

interface PersonalListItem {
  id: string                    // Auto-generated unique ID

🎨 UX Design

Sliding Panel Behavior

Opening:

• Click "My List" button in header
• Click "Push to my list" and then "View List" in toast
• Slides in from right with smooth animation
• Takes 30-70% of screen width (resizable)

Resizing:

• Drag the vertical handle to adjust width
• Min width: 30% of screen
• Max width: 70% of screen
• Smooth spring animation

Closing:

• Click X button in panel header
• Click "My List" button again in header
• Slides out to right with animation

Visual Hierarchy

Main Content Area:

• Takes remaining space (100% width when closed, 30-70% when open)
• Maintains all functionality
• Keeps scroll position

Panel:

• Fixed position on right
• Full height
• Shadow and border for depth
• Blur backdrop on header

Empty States

No Items Yet:

• Centered icon (folder)
• Friendly message
• Clear call-to-action
• Gradient text highlight

Zero State in Editor:

• Placeholder text in editor
• Helpful hints about slash commands
• Preview shows empty state

🚀 Usage Examples

Adding an Item

// From repository card
<PushToListButton
  title="React"
  description="A JavaScript library for building user interfaces"
  url="https://react.dev"
  repository="facebook/react"
  variant="outline"
  size="sm"
/>

Accessing Store

import { usePersonalListStore } from '@/lib/personal-list-store'

function MyComponent() {
  const { items, addItem, openEditor } = usePersonalListStore()

  return (
    <div>
      <p>{items.length} items in list</p>
      <button onClick={openEditor}>Open Editor</button>
    </div>
  )
}

Exporting Data

const { exportList, generateMarkdown } = usePersonalListStore()

// Export as JSON
const jsonData = exportList()
console.log(JSON.stringify(jsonData, null, 2))

// Export as Markdown
const markdown = generateMarkdown()
console.log(markdown)

📱 Responsive Design

Desktop (≥768px):

• Full sliding panel with resizable width
• Split view available
• All toolbar buttons visible

Tablet (768px-1024px):

• Sliding panel with smaller default width
• Split view with narrower editor
• Some labels hidden

Mobile (<768px):

• Full-screen modal instead of sliding panel
• Stack views (no split view)
• Compact toolbar with icons only
• Sheet component for mobile menu

🎯 Integration Points

Header Navigation

// components/layout/app-header.tsx
<Button asChild>
  <Link href="/my-list">
    <ListIcon className="h-4 w-4" />
    My List
    {items.length > 0 && (
      <Badge>{items.length}</Badge>
    )}
  </Link>
</Button>

List Detail Pages

// app/list/[id]/page.tsx
<SlidingPanel isOpen={isEditorOpen} onClose={closeEditor}>
  <SlidingPanelMain>
    {/* Main content with repositories */}
  </SlidingPanelMain>

  <SlidingPanelSide title="My Awesome List">
    <PersonalListEditor />
  </SlidingPanelSide>
</SlidingPanel>

Standalone Page

// app/my-list/page.tsx
<PersonalListEditor />
