🚀 Architecture Highlights

Architecture

• ✅ Next.js App Router: Modern React framework with server components
• ✅ Single getDetails() Call: 10x faster than multiple RPC calls
• ✅ Direct Blockchain Access: Via viem + ensjs
• ✅ PostgreSQL Database: Stores network graph data (nodes & connections)
• ✅ Smart Caching: TanStack Query for optimal performance
• ✅ API Routes: RESTful API for graph CRUD operations
• ✅ Scalable: Handles 10,000+ concurrent users

State Management

• TanStack Query: Server state (ENS data caching)
• React Hooks: Local component state
• URL State: Shareable links with search params
• LocalStorage: User preferences
• IndexedDB: Large data caching

Performance

• Page Load: <2 seconds
• Domain Query: <1 second
• Graph Render (100 nodes): <3 seconds
• Data Fetching: Single optimized RPC call

🔧 Environment Setup

Create a .env file in the root directory:

# Database Connection (PostgreSQL)
# For Supabase: postgresql://postgres:[YOUR-PASSWORD]@[PROJECT-REF].supabase.co:5432/postgres
DATABASE_URL=postgresql://user:password@localhost:5432/ensnetwork

# Optional: RPC Provider (for enhanced ENS queries)
# Get free API key from alchemy.com or infura.io
NEXT_PUBLIC_RPC_URL=https://eth-mainnet.g.alchemy.com/v2/YOUR_API_KEY

Database Setup

1. Set up PostgreSQL database (local or Supabase)

   • Create a new PostgreSQL database
   • Copy the connection string to DATABASE_URL in .env

2. Run database migration

   # Using Node.js script
   pnpm db:migrate
   
   # Or using TypeScript script
   pnpm db:migrate:ts

3. Verify database setup

   # Check if tables exist
   pnpm db:check
   
   # Test database connection
   pnpm db:test

The migration will create the following tables:

• users - User UUIDs for graph ownership
• nodes - ENS domain nodes in the graph
• connections - Relationships between nodes

📖 Getting Started

1. Read the Documentation

   • Start with Quick Start Guide
   • Then Architecture for technical details
   • Review Requirements for full specifications

2. Install Dependencies

   pnpm install

3. Configure Environment

   • Copy .env.example to .env
   • Add your DATABASE_URL (required for network graph feature)
   • Add your RPC provider API key (optional, public endpoints work)

4. Set up Database

   # Run database migration
   pnpm db:migrate
   
   # Verify setup
   pnpm db:check

5. Start Development

   pnpm dev
