Mobile Responsiveness - Quick Integration

Files Created ✓

1. src/components/layout/mobile-bottom-nav.tsx - Mobile bottom navigation bar
2. src/components/layout/full-screen-overlay.tsx - Full-screen mobile overlay with cancel button
3. src/components/layout/topbar.tsx - Updated with enhanced dropdown (mobile menu items)

Quick Integration Steps

Step 1: Import Mobile Components

Add to src/components/layout/main-layout.tsx:

import { MobileBottomNav } from './mobile-bottom-nav';
import { FullScreenOverlay } from './full-screen-overlay';

Step 2: Add Mobile State

After existing state declarations:

const [mobileTab, setMobileTab] = useState<'chats' | 'contacts' | 'wallet' | 'settings' | 'more'>('chats');

Step 3: Update Sidebar Classes

Change the left sidebar div from:

<div className={`${currentUser && selectedConversation ? 'hidden md:flex' : 'flex'} w-full md:w-80 ...`}>

To:

<div className="hidden md:flex w-80 bg-gradient-to-b from-black via-gray-900 to-black border-r border-violet-900/20 flex-col">

Step 4: Update Main Chat Area

Change from:

<div className={`${currentUser && !selectedConversation ? 'hidden md:flex' : 'flex'} flex-1 flex-col ...`}>

To:

<div className="flex-1 flex flex-col bg-gradient-to-br from-gray-950 via-black to-gray-950 pb-16 md:pb-0">

Step 5: Add Mobile Bottom Nav

Before closing the main div, add:

{currentUser && (
  <MobileBottomNav
    activeTab={mobileTab}
    onTabChange={setMobileTab}
    unreadCount={0}
    onOpenProfile={() => {}}
    onOpenSecurity={() => {}}
    onOpenStats={() => {}}
    onOpenNewChat={() => setShowNewChat(true)}
    onOpenNewContact={() => {}}
  />
)}

Step 6: Handle Mobile Tab Switching

Add logic to show/hide content based on mobileTab:

{/* Mobile: Conditional rendering */}
<div className="md:hidden h-full">
  {mobileTab === 'chats' && (
    // Show chat interface or conversation list
  )}
  {mobileTab === 'wallet' && (
    <FullScreenOverlay isOpen={true} onClose={() => setMobileTab('chats')} title="Wallet">
      {/* Wallet content */}
    </FullScreenOverlay>
  )}
  {mobileTab === 'settings' && (
    <FullScreenOverlay isOpen={true} onClose={() => setMobileTab('chats')} title="Settings">
      <SettingsOverlay onClose={() => setMobileTab('chats')} />
    </FullScreenOverlay>
  )}
</div>

{/* Desktop: Existing layout */}
<div className="hidden md:block">
  {/* Current chat interface code */}
</div>

  // ... existing state ...

      <Topbar {...props} />
      
      <div className="flex-1 flex overflow-hidden">

        <div className="hidden md:flex w-80">
          {/* Existing sidebar content */}
        </div>

        {/* Main Area - responsive */}
        <div className="flex-1 pb-16 md:pb-0">
          {/* Your chat interface */}
        </div>
      </div>

      {/* Mobile Bottom Nav - only on mobile */}
      {currentUser && (
        <MobileBottomNav
          activeTab={mobileTab}
          onTabChange={setMobileTab}
          onOpenNewChat={() => setShowNewChat(true)}
          {...otherProps}
        />
      )}
    </div>
  );
}
