# Database Integration Complete ✅
|
|
|
|
The VIBN frontend is now connected to your PostgreSQL database and displaying **real data**!
|
|
|
|
## 🔗 What's Connected
|
|
|
|
### Database Connection
|
|
- **Location**: `lib/db.ts`
|
|
- **Connection**: Railway PostgreSQL (same as your Extension proxy)
|
|
- **SSL**: Enabled with `rejectUnauthorized: false`
|
|
|
|
### Type Definitions
|
|
- **Location**: `lib/types.ts`
|
|
- **Types**: Session, WorkCompleted, Project, ArchitecturalDecision, ApiEndpoint, DashboardStats
|
|
|
|
### API Routes Created
|
|
|
|
#### 1. `/api/stats` - Dashboard Statistics
|
|
Fetches aggregated metrics:
|
|
- Total sessions count
|
|
- Total AI cost
|
|
- Total tokens used
|
|
- Total duration
|
|
- Work items completed
|
|
|
|
**Usage**: `GET /api/stats?projectId=1`
|
|
|
|
#### 2. `/api/sessions` - Sessions List
|
|
Fetches session data with:
|
|
- Conversation history (messages)
|
|
- File changes
|
|
- Token counts
|
|
- Cost estimates
|
|
- AI model used
|
|
- IDE information
|
|
- Git branch/commit info
|
|
|
|
**Usage**: `GET /api/sessions?projectId=1&limit=20`
|
|
|
|
#### 3. `/api/work-completed` - Work Items
|
|
Fetches completed work items:
|
|
- Title and description
|
|
- Category (frontend/backend/database/etc.)
|
|
- Files modified
|
|
- Session linkage
|
|
- GitHub commit info
|
|
|
|
**Usage**: `GET /api/work-completed?projectId=1&limit=20`
|
|
|
|
## 📊 Pages Updated with Real Data
|
|
|
|
### ✅ Overview Page (`/[projectId]/overview`)
|
|
- **Real Stats**: Sessions, Cost, Tokens, Work Items
|
|
- **Calculation**: Duration shown in hours
|
|
- **Formatting**: Cost shows 2 decimals, tokens show M notation
|
|
|
|
### ✅ Sessions Page (`/[projectId]/sessions`)
|
|
- **Real Sessions**: Pulled from `sessions` table
|
|
- **Details Shown**:
|
|
- Duration in minutes
|
|
- Message count
|
|
- Cost per session
|
|
- AI model (Claude/GPT/Gemini)
|
|
- IDE (Cursor/VS Code)
|
|
- Git branch
|
|
- **Empty State**: Shows when no sessions exist
|
|
|
|
## 🗄️ Database Tables Used
|
|
|
|
```sql
|
|
-- Sessions table
|
|
SELECT * FROM sessions WHERE project_id = 1;
|
|
|
|
-- Work completed table
|
|
SELECT * FROM work_completed WHERE project_id = 1;
|
|
|
|
-- Projects table (for metadata)
|
|
SELECT * FROM projects;
|
|
```
|
|
|
|
## 🔄 Data Flow
|
|
|
|
```
|
|
PostgreSQL (Railway)
|
|
↓
|
|
Next.js API Routes (/api/*)
|
|
↓
|
|
Server Components (pages)
|
|
↓
|
|
UI Components (cards, badges, etc.)
|
|
```
|
|
|
|
## 📝 Environment Variables
|
|
|
|
The database URL is hardcoded in `lib/db.ts` (same as Extension proxy):
|
|
|
|
```typescript
|
|
const DATABASE_URL = 'postgresql://postgres:jhsRNOIyjjVfrdvDXnUVcXXXsuzjvcFc@metro.proxy.rlwy.net:30866/railway';
|
|
```
|
|
|
|
For production, move to environment variable:
|
|
```bash
|
|
DATABASE_URL=postgresql://...
|
|
```
|
|
|
|
## 🎯 What's Now Live
|
|
|
|
1. **Overview Dashboard**
|
|
- Real session count
|
|
- Real total cost
|
|
- Real token usage
|
|
- Real work items completed
|
|
|
|
2. **Sessions List**
|
|
- Shows actual AI coding sessions
|
|
- Displays conversation history metadata
|
|
- Shows cost per session
|
|
- Links to file changes
|
|
|
|
3. **Empty States**
|
|
- Graceful handling when no data exists
|
|
- Helpful CTAs to get started
|
|
|
|
## 🔜 Next Steps
|
|
|
|
### Data Not Yet Connected:
|
|
- **Features** page (need to populate `features` table)
|
|
- **API Map** page (need to populate `api_endpoints` table)
|
|
- **Architecture** page (need to populate `architectural_decisions` table)
|
|
- **Analytics** charts (need chart library like Recharts)
|
|
|
|
### To Connect These:
|
|
1. Run Gemini analyzer on existing sessions → populates tables
|
|
2. Create API routes for features/api-endpoints/decisions
|
|
3. Update pages to fetch from new routes
|
|
