Homepage.dev Real-time Implementation Plan

Standalone platform implementation with dedicated Convex architecture and sub-100ms global sync

🎯 Executive Summary

This implementation plan details the transformation of homepage.dev from a simple landing page to a production-ready standalone real-time collaborative platform. Using a purpose-built three-project Convex architecture, we will deliver sub-100ms sync latency globally while supporting unlimited extensibility through the module marketplace.

Key Strategic Changes from Original Plan:

✅ Standalone Clerk Authentication (not multi-tenant do.dev integration)
✅ Three-Project Convex Architecture for maximum scalability and isolation
✅ 20-Week Production Timeline (not 8 weeks) with realistic milestones
✅ Enterprise-First Features built from day one
✅ Independent Platform Strategy for unlimited growth potential

1.2 Real-time Data Flow Architecture

// Real-time subscription patterns
interface RealtimeArchitecture {
  // Live data streams
  liveMetrics: {
    activeUsers: number
    modulesInstalled: number
    apiCallsPerSecond: number
    systemHealth: HealthStatus
  }
  
  // Collaborative features
  collaboration: {
    activeEditors: User[]
    cursorPositions: CursorPosition[]
    liveChanges: ChangeEvent[]
  }
  
  // Module communications
  moduleEvents: {
    interModuleMessages: Message[]
    sharedState: SharedState
    notifications: Notification[]
  }
}

2.2 Data Flow Patterns

// Unidirectional data flow with Convex subscriptions
const dataFlow = {
  // User actions → Convex mutations → Real-time updates to all clients
  userAction: "drag module",
  convexMutation: "updateModulePosition",
  subscription: "subscribeToLayout",
  broadcast: "all connected clients receive update < 100ms"
}

6. Performance Considerations for Realtime Updates

6.1 Optimization Strategies

interface PerformanceOptimizations {
  // Subscription management
  subscriptions: {
    debouncing: 16, // ms (60fps)
    throttling: 100, // ms for non-critical updates
    batchSize: 50, // max updates per batch
  }
  
  // Caching layers
  caching: {
    moduleStateCache: "5 minutes",
    userPresenceCache: "30 seconds",
    staticAssetCache: "1 hour",
  }
  
  // Network optimization
  network: {
    compression: "gzip",
    deltaSync: true, // Only send changes
    reconnectionStrategy: "exponential-backoff",
  }
}

6.2 Scalability Targets

  // Integration tests
  integration: {
    multiUserSync: "Playwright with multiple browsers",
    moduleComms: "Test message passing",
    performanceTests: "Load testing with K6",
  },
  
  // E2E tests
  e2e: {
    userJourneys: "Complete workflows",
