Dashboard Counters Implementation

Overview

Created a comprehensive dashboard with real-time statistics counters from the backend API, split into reusable Vue components.

Backend Changes

1. New Dashboard Handler (internal/handlers/dashboard.go)

Created a new handler that provides comprehensive statistics:

Endpoint: GET /api/dashboard

Response Structure:

{
  "projects": {
    "total": 10,
    "active": 8,
    "archived": 2
  },
  "agents": {
    "total": 15,
    "active": 12,
    "idle": 2,
    "offline": 1
  },
  "tasks": {
    "total": 45,
    "pending": 10,
    "in_progress": 15,
    "done": 18,
    "blocked": 2
  },
  "contexts": {
    "total": 30
  }
}

Features:

• Uses PostgreSQL COUNT(*) FILTER (WHERE ...) for efficient aggregation
• Error handling with fallback to zero values
• Separate statistics for each entity type

2. Updated Server Configuration (cmd/server/main.go)

• Added dashboardHandler initialization
• Registered /api/dashboard route
• Handler connected to database for real-time data

Frontend Changes

1. New StatCard Component (web/src/components/StatCard.vue)

Purpose: Reusable statistics card with breakdown details

Props:

• title (String, required) - Card title
• value (Number/String, required) - Main statistic value
• icon (String) - Emoji icon
• iconBgColor (String) - Background color for icon
• breakdown (Array) - Detailed breakdown with labels, values, and colors

Features:

• Hover animations and transitions
• Flexible breakdown section
• Color-coded values
• Responsive design

Example Usage:

<StatCard
  title="Projects"
  :value="stats.projects.total"
  icon="📁"
  iconBgColor="#3b82f6"
  :breakdown="[
    { label: 'Active', value: stats.projects.active, color: '#10b981' },
    { label: 'Archived', value: stats.projects.archived, color: '#6b7280' }
  ]"
/>

2. Updated Dashboard View (web/src/views/Dashboard.vue)

New Features:

• Fetches dashboard stats from /api/dashboard endpoint
• Uses StatCard component for all statistics
• Loading and error states
• Four main stat cards:
  1. Projects - Total, Active, Archived
  2. Agents - Total, Active, Idle, Offline
  3. Tasks - Total, Pending, In Progress, Blocked
  4. Completed - Done tasks + Contexts count

Components Structure:

• StatCard components for metrics
• Recent Projects section (unchanged)
• Active Agents section (unchanged)
• Recent Tasks section (unchanged)

Statistics Breakdown

Projects Counter

• Total: All projects in the system
• Active: Projects with status = 'active'
• Archived: Projects with status = 'archived'

Agents Counter

• Total: All registered agents
• Active: Agents currently working (status = 'active')
• Idle: Agents available but not working (status = 'idle')
• Offline: Agents not connected (status = 'offline')

Tasks Counter

• Total: All tasks created
• Pending: Tasks waiting to start (status = 'pending')
• In Progress: Tasks currently being worked on (status = 'in_progress')
• Blocked: Tasks that are blocked (status = 'blocked')

Completed Counter

• Done: Successfully completed tasks (status = 'done')
• Contexts: Total documentation/context entries

Benefits

1. Real-time Data: Statistics fetched directly from database
2. Reusable Component: StatCard can be used elsewhere in the application
3. Visual Hierarchy: Color-coded breakdown for quick insights
4. Scalable: Easy to add more statistics
5. Performance: Single API call for all dashboard data
6. Maintainable: Separated concerns between backend and frontend

API Usage Example

# Fetch dashboard statistics
curl http://localhost:8080/api/dashboard

# Response
{
  "projects": {"total": 5, "active": 4, "archived": 1},
  "agents": {"total": 8, "active": 6, "idle": 1, "offline": 1},
  "tasks": {"total": 20, "pending": 5, "in_progress": 8, "done": 6, "blocked": 1},
  "contexts": {"total": 12}
}

Future Enhancements

1. Add time-based filtering (today, this week, this month)
2. Add trend indicators (↑ ↓) comparing to previous period
3. Add charts/graphs for visual representation
4. Add real-time updates via WebSocket
5. Add export functionality for reports
6. Add user-specific statistics
7. Add performance metrics (avg completion time, etc.)

Testing

1. Backend: Build verified with go build ./cmd/server
2. Frontend: No compilation errors in Vue components
3. API: Endpoint registered and handler connected to database

Files Modified

Backend:

• internal/handlers/dashboard.go (NEW)
• cmd/server/main.go (Modified - added dashboard handler and route)

Frontend:

• web/src/components/StatCard.vue (NEW)
• web/src/views/Dashboard.vue (Modified - integrated StatCard and API call)
