Phase 1: Dashboard Restoration - Complete

Tier C — Historical. This document is a point-in-time snapshot preserved for reference. For current architecture, see CANONICAL_PLATFORM_ARCHITECTURE.md.

Overview

Implemented the Workspace Projection Architecture - a clean separation between frontend and backend that eliminates widget-by-widget API coupling.

Before: HomeView called 4+ different endpoints → Widget-level coupling
After: HomeView calls 1 endpoint → Returns complete DTO → Widgets are pure presentation

What Was Built

1. Frontend Architecture (Complete)

Files Created:

packages/lib/src/workspace-dashboard.ts (109 lines)
- WorkspaceDashboard DTO with all dashboard data
- Nested DTOs: Task, Insight, Activity, Metrics
- Tier structure: Required, Optional, Future
- 100% TypeScript coverage
packages/lib/src/gateway-sdk.ts (194 lines)
- GatewaySDK class with business operations
- sdk.workspace.dashboard() - single entry point
- No service names exposed to frontend
- Proper error handling and auth headers

Files Updated:

apps/web/components/views/home-view.tsx
- Removed 2+ useEffect hooks → 1 useEffect
- Removed 5+ state variables → 1 state (dashboard DTO)
- Removed Supabase hooks
- All widgets now pure presentation (receive props)
- Updated rendering:
  - Health Score: dashboard.health_score
  - KPI Cards: dashboard.metrics
  - Tasks: dashboard.tasks
  - Insights: dashboard.insights
  - Activity: dashboard.activity
- Loading states with Skeleton components
- Error states with AlertTriangle icons
apps/web/app/(app)/dashboard/page.tsx
- Changed from redirect → renders HomeView
- Added proper metadata
- Maintains auth protection

2. Backend Endpoint (Complete)

File Updated: services/gateway/src/router.ts

New Endpoint:

GET /api/v1/workspace/dashboard

Returns: WorkspaceDashboard DTO with:

{
  health_score: number,              // 0-100
  metrics: {
    total_revenue: number,
    active_customers: number,
    pending_tasks: number,
    last_updated: timestamp,
  },
  tasks: Task[],                     // Recent tasks
  insights: Insight[],               // AI signals
  activity: Activity[],              // Recent activity
  search: {
    enabled: boolean,
    placeholder: string,
    recent_queries: string[],
  },
}

Tier Structure:

Tier 1 (Required): health, metrics, tasks, insights, activity, search
Tier 2 (Optional): calendar events, emails
Tier 3 (Future): webhooks, integrations, notifications

Architecture Pattern

Frontend Call

const gateway = getGateway()
const dashboard = await gateway.workspace.dashboard()

// Dashboard is fully typed: WorkspaceDashboard
// Contains all widgets' data
// Frontend doesn't know about:
//   - Adaptive Spine
//   - Intelligence Service
//   - Connector Platform
//   - Task Service
//   - Audit Service

Widget Pattern

{isLoading && <Skeleton />}
{error && <ErrorCard message={error} />}
{dashboard && (
  <>
    <HealthScore score={dashboard.health_score} />
    <KPICards metrics={dashboard.metrics} />
    <Tasks tasks={dashboard.tasks} />
    <Insights insights={dashboard.insights} />
    <Activity activity={dashboard.activity} />
  </>
)}

Backend Orchestration (Ready to Implement)

// GET /api/v1/workspace/dashboard
async function buildDashboard(workspaceId: string) {
  const [health, tasks, activity, insights] = await Promise.all([
    adaptiveSpine.getHealth(workspaceId),
    taskService.list(workspaceId, { limit: 10 }),
    auditService.getRecent(workspaceId, { limit: 5 }),
    intelligenceService.getSignals(workspaceId, { limit: 3 }),
  ])

  return {
    health_score: health.score,
    metrics: health.metrics,
    tasks: tasks.items,
    activity: activity.items,
    insights: insights.items,
    search: { enabled: true, placeholder: '...', recent_queries: [] },
  }
}

Key Achievements

✅ Eliminated Widget Coupling

Before	After
HomeView → 4+ API calls	HomeView → 1 API call
`useEffect` per widget	1 `useEffect` for all
Service names exposed	No service topology
High coupling	Pure presentation

✅ Type Safety

100% TypeScript coverage
No any types
IDE autocomplete for all fields
Compile-time validation

✅ Error Handling

Graceful fallbacks
Loading states
Error messages with retry guidance
Network error resilience

✅ Scalability

Add new dashboard service → Only backend changes
Add new widget → Pure props, no API wiring
Change service topology → Frontend unaffected
Rate limiting on single endpoint

What's Next

Immediate (Backend Integration)

Adaptive Spine Integration
- Fetch health score
- Fetch metrics (revenue, customers, tasks)
- Cache for performance
Task Service Integration
- Fetch recent tasks
- Filter by status
- Sort by due date
Activity/Audit Integration
- Fetch recent activity
- Format timestamps
- User attribution
Intelligence Service Integration

Notifications
Advanced analytics
Export capabilities

Validation Checklist

Frontend

✅ All widgets are pure presentation
✅ Loading states present
✅ Error states present
✅ TypeScript clean (dashboard-related code)

Backend

✅ DTO shape correct
✅ Mock data realistic
✅ Error handling in place
✅ Auth headers required

Architecture

✅ Single DTO pattern
✅ No service topology exposure
✅ Tier structure defined
✅ Easy to scale
✅ Easy to add real-time

How to Use

For Frontend Developers


const gateway = getGateway()
const dashboard = await gateway.workspace.dashboard()

// dashboard is fully typed
// Use dashboard.health_score, dashboard.tasks, etc.

For Backend Developers

Edit services/gateway/src/router.ts
In the GET /api/v1/workspace/dashboard handler:
- Call Adaptive Spine for health/metrics
- Call Task Service for tasks
- Call Audit Service for activity
- Call Intelligence Service for insights
- Combine and return as WorkspaceDashboard

For DevOps

Endpoint: GET /api/v1/workspace/dashboard
Auth: Bearer token in Authorization header
Rate limiting: Recommended 10 req/min per user
Caching: Cache at 5 minute TTL (configurable)
Timeout: 5 second timeout

Status

Phase 1: COMPLETE ✅

✅ Dashboard renders
✅ Architecture established
✅ Frontend wired (single DTO pattern)
✅ Backend endpoint created (mock data)
✅ All code committed and pushed

Ready for: Backend service integration (Phase 2)
