# PART 2: CORE FEATURES SETUP

## 6. Database & Tables

### Creating Your First Table

**Method 1: Prompt-Based** (Recommended)

| Step | Prompt Example | Result |
|------|---------------|--------|
| 1 | "Create a posts table with title, content, user_id" | Table created |
| 2 | "Add RLS so users only see their own posts" | RLS policy added |
| 3 | Click "Approve" | Table live in database |

**Method 2: Advanced SQL** (For complex schemas)

| Step | Action | When to Use |
|------|--------|-------------|
| 1 | Go to Cloud → Database | Need custom SQL |
| 2 | Write SQL directly | Complex migrations |
| 3 | Run migration | Apply changes |

### Table Best Practices

| Practice | SQL Pattern | Why |
|----------|-------------|-----|
| **Always use UUID** | `id uuid PRIMARY KEY DEFAULT gen_random_uuid()` | Better than integers |
| **Add timestamps** | `created_at timestamptz DEFAULT now()` | Audit trail |
| **User ownership** | `user_id uuid REFERENCES auth.users(id)` | For RLS |
| **Soft deletes** | `deleted_at timestamptz` | Don't lose data |
| **JSON for flexibility** | `metadata jsonb DEFAULT '{}'::jsonb` | Flexible schema |

### Real Example: Startup Profiles

**From medellin-ai-hub project**:
```sql
CREATE TABLE startup_profiles (
  id uuid PRIMARY KEY DEFAULT gen_random_uuid(),
  profile_id uuid REFERENCES profiles(id) ON DELETE CASCADE,
  startup_name text NOT NULL,
  product_description text,
  tech_stack jsonb DEFAULT '[]'::jsonb,
  readiness_score integer,
  created_at timestamptz DEFAULT now(),
  updated_at timestamptz DEFAULT now()
);

-- Enable RLS
ALTER TABLE startup_profiles ENABLE ROW LEVEL SECURITY;

-- Only owner can access
CREATE POLICY "users_own_profiles"
  ON startup_profiles FOR ALL
  USING (profile_id IN (
    SELECT id FROM profiles WHERE user_id = auth.uid()
  ));
```

---

## 7. User Authentication

### Setup Methods

**Method 1: One Prompt** (Fastest)

| Prompt | What Gets Created | Time |
|--------|-------------------|------|
| "Add user accounts" | Signup, login, profiles | 30 sec |
| "Add password reset" | Reset flow | 30 sec |
| "Add Google login" | OAuth (requires config) | 5 min |

**Method 2: Granular Control**

| Step | Prompt | Component Created |
|------|--------|-------------------|
| 1 | "Create signup page" | Registration form |
| 2 | "Add email verification" | Verification flow |
| 3 | "Create login page" | Login form |
| 4 | "Add password reset" | Reset flow |

### Auto-Created Components

| Component | Location | Purpose |
|-----------|----------|---------|
| `auth.users` table | Database | Core auth data |
| `profiles` table | Database | User profiles |
| Signup page | `/signup` or `/auth` | Registration |
| Login page | `/login` or `/auth` | Authentication |
| RLS policies | Database | User data isolation |

### Protected Routes Pattern

**Lovable auto-generates**:
```typescript
// Only logged-in users can access
<ProtectedRoute>
  <Dashboard />
</ProtectedRoute>
```

**Manual check**:
```typescript
const { isSignedIn } = useAuth();
if (!isSignedIn) return <Navigate to="/auth" />;
```

## 8. File Storage

### Setup Process

| Step | Action | Command/Prompt | Result |
|------|--------|----------------|--------|
| 1 | Request upload | "Let users upload profile photos" | Storage enabled |
| 2 | Specify constraints | "Max 5MB, JPG/PNG only" | Validation added |
| 3 | Organize structure | "Store in user_id/photos/" | Folder structure |
| 4 | Test upload | Use preview | Verify works |

### Storage Configuration

| Setting | Prompt Example | Default |
|---------|---------------|---------|
| **File types** | "Accept PDF and DOCX only" | All types |
| **Size limit** | "Max 10MB per file" | No limit |
| **Access** | "Private, signed URLs" | Public |
| **Organization** | "Organize by user_id" | Flat structure |

### Real Examples from Videos

| Use Case | Storage Setup | Access Pattern | Video |
|----------|---------------|----------------|-------|
| **Profile photos** | Public bucket, 2MB limit | Direct URLs | 004 |
| **Brand assets** | Private, organized by client | Signed URLs | 007 |
| **Generated images** | Public, by user_id | Direct URLs | 001 |
| **Document uploads** | Private, 10MB limit | Signed URLs | 002 |

# PART 4: PRODUCTION DEPLOYMENT

## 16. Security Hardening

### Essential Security Checklist

| Security Item | How to Implement | Priority | Video Evidence |
|---------------|------------------|----------|----------------|
| **JWT Verification** | `verify_jwt = true` in config.toml | 🔴 Critical | All videos |
| **RLS Policies** | Auto-created, verify in Cloud → Database | 🔴 Critical | All videos |
| **Ownership Checks** | Verify user owns resource | 🔴 Critical | medellin-ai-hub |
| **Input Validation** | Use Zod schemas | 🟡 High | Best practice |
| **Rate Limiting** | Implement per-user limits | 🟡 High | Best practice |
| **Secrets in Env** | Never in code | 🔴 Critical | All videos |
| **CORS Headers** | Auto-added by Lovable | ✅ Done | All videos |
| **HTTPS Only** | Auto in production | ✅ Done | Default |

### JWT Verification Setup

**File**: `supabase/config.toml`

| Function Type | Setting | Example |
|---------------|---------|---------|
| User-facing (chat, profile) | `verify_jwt = true` | ✅ Protected |
| Public webhooks | `verify_jwt = false` | ⚠️ Verify signature instead |
| Admin functions | `verify_jwt = true` | ✅ Protected |

**Real Config** (from medellin-ai-hub):
```toml
[functions.chat]
verify_jwt = true  # ✅ User must be logged in

[functions.analyze-startup]
verify_jwt = true  # ✅ Protected

[functions.webhook]
verify_jwt = false  # Public, but validates signature
```

### Ownership Verification Pattern

```typescript
// In every edge function accessing user data:

// 1. Get authenticated user
const { data: { user }, error } = await supabase.auth.getUser();
if (error || !user) {
  return new Response("Unauthorized", { status: 401 });
}

// 2. Verify user owns the resource
const { data: resource } = await supabase
  .from('resources')
  .select('*')
  .eq('id', resourceId)
  .eq('user_id', user.id)  // ✅ Ownership check
  .single();

if (!resource) {
  return new Response("Forbidden", { status: 403 });
}

// 3. Proceed with operation
```

## 17. Performance Optimization

### Model Selection for Speed

| Scenario | Use This | Not This | Speed Gain |
|----------|----------|----------|------------|
| Classification | Gemini Flash Lite | GPT-5 | 10x faster |
| Chat messages | Gemini Flash | GPT-5 Mini | 3x faster |
| Simple extraction | Gemini Flash Lite | Gemini Flash | 2x faster |
| Complex reasoning | Gemini Flash | Gemini Pro | 2x faster (acceptable quality) |

### Caching Strategy

**From Video 002 (Business Chatbot)**:

| Cache What | How | Benefit |
|------------|-----|---------|
| Common questions | Store in database | 100x faster |
| Vector search results | TTL cache 1 hour | 10x faster |
| Brand voice analysis | Store in MemZero | One-time cost |

**Implementation**:
```typescript
// Check cache first
const cached = await getCachedResponse(question);
if (cached) return cached;

// If not cached, call AI
const response = await callAI(question);
await cacheResponse(question, response, 3600); // 1 hour TTL
return response;
```

### Database Query Optimization

| Optimization | Example | Benefit |
|--------------|---------|---------|
| **Select only needed columns** | `.select('id, name')` | Faster queries |
| **Add indexes** | On user_id, created_at | 100x faster |
| **Use pagination** | `.range(0, 9)` | Less data transferred |
| **Prefetch relations** | `.select('*, author:profiles(*)')` | Fewer queries |

## 18. Monitoring & Analytics

### Built-in Monitoring

**Location**: Cloud → Usage, Cloud → Logs

| Metric | Where to Find | What to Watch |
|--------|---------------|---------------|
| **AI usage** | Cloud → AI Usage | Model choice, request count |
| **Cloud usage** | Cloud → Overview | Database size, function calls |
| **Edge function logs** | Cloud → Edge Functions → Logs | Errors, performance |
| **User growth** | Cloud → Users | Signups, active users |
| **Storage** | Cloud → Storage | File count, size |

### Custom Tracking Table

**Pattern from Videos**:

```sql
CREATE TABLE ai_operations (
  id uuid PRIMARY KEY DEFAULT gen_random_uuid(),
  user_id uuid REFERENCES auth.users(id),
  operation_type text,  -- 'chat', 'generation', 'analysis'
  model text,
  tokens_estimated integer,
  latency_ms integer,
  status text,  -- 'success', 'error', 'rate_limited'
  created_at timestamptz DEFAULT now()
);

-- Query for cost analysis
SELECT 
  DATE(created_at) as date,
  operation_type,
  COUNT(*) as operations,
  SUM(tokens_estimated) * 0.0015 as estimated_cost
FROM ai_operations
WHERE created_at > NOW() - INTERVAL '30 days'
GROUP BY DATE(created_at), operation_type;
```

### Alerts to Set Up

| Alert | Threshold | Action |
|-------|-----------|--------|
| Daily AI cost | > $10 | Email notification |
| Error rate | > 5% | Investigate immediately |
| Response time | > 5 sec | Optimize queries |
| User signups spike | 10x normal | Check for abuse |
