Key Components

Landing Page (app/page.tsx)

Sophisticated marketing site featuring:

export default function Home() {
  return (
    <>
      <LandingNav />
      <main className="gradient-farm animate-pop">
        <Hero />
        <FeaturesSection />
        <AudienceSection />
        <Footer />
      </main>
    </>
  );
}

Authentication Context (context/AuthContext.tsx)

Comprehensive auth state management:

export function AuthProvider({ children }: { children: ReactNode }) {
  const [user, setUser] = useState<User | null>(null);
  const [session, setSession] = useState<Session | null>(null);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    const { data: authListener } = supabase.auth.onAuthStateChange(
      (event, session) => {
        setSession(session);
        setUser(session?.user ?? null);
        setLoading(false);
      }
    );

    return () => authListener?.subscription?.unsubscribe();
  }, []);
  // ... auth methods
}

UI Components (components/ui/)

Type-safe component variants:

const buttonVariants = cva(
  "inline-flex items-center justify-center gap-2 whitespace-nowrap rounded-md text-sm font-medium transition-all",
  {
    variants: {
      variant: {
        default: "bg-primary text-primary-foreground shadow-xs hover:bg-primary/90",
        destructive: "bg-destructive text-white shadow-xs hover:bg-destructive/90",
        outline: "border bg-background shadow-xs hover:bg-accent",
        // ... more variants
      },
      size: {
        default: "h-9 px-4 py-2",
        sm: "h-8 rounded-md gap-1.5 px-3",
        lg: "h-10 rounded-md px-6",
        icon: "size-9",
      },
    },
  }
);

State Management Strategy

Context Providers

  • AuthContext - User authentication state
  • ThemeContext - Dark/light mode management
  • Global State - Application-wide state management

Data Flow

  1. Supabase Client → Real-time data synchronization
  2. Context Providers → State distribution
  3. Custom Hooks → Reusable state logic
  4. Components → UI state consumption

Routing & Navigation

App Router Structure

  • Route Groups - Organized page structure
  • Dynamic Routes - Parameter-based routing
  • Nested Layouts - Hierarchical page structure
  • Loading States - Optimized user experience
  • LandingNav - Marketing site navigation
  • AuthenticatedNav - Post-login navigation
  • Mobile Navigation - Responsive menu system

Styling System

Tailwind Configuration

module.exports = {
  content: ["./src/**/*.{js,ts,jsx,tsx}"],
  theme: {
    extend: {
      colors: {
        // Custom color palette
      },
      animation: {
        // Custom animations
      },
    },
  },
  plugins: [
    // Additional plugins
  ],
};

Custom CSS Classes

  • gradient-farm - Brand gradient background
  • glass - Glass morphism effects
  • card-shadow - Consistent shadow system
  • animate-pop - Entrance animations

Data Integration

Supabase Connection

import { createClient } from '@supabase/supabase-js';

const supabaseUrl = process.env.NEXT_PUBLIC_SUPABASE_URL;
const supabaseAnonKey = process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY;

export const supabase = createClient(supabaseUrl, supabaseAnonKey);
