# Campaigns Module

## Overview

The Campaigns module manages advocacy email campaigns targeting elected representatives. It provides comprehensive CRUD operations with rich feature flags, automatic slug generation, and role-based visibility controls. Campaigns integrate with the representative lookup system, email sending queue, and public response wall.

**Key Features:**

- Full CRUD with pagination, search, and status filtering
- Auto-generated slugs from campaign titles (collision-safe)
- Feature flags (SMTP email, mailto links, response wall, highlighting, etc.)
- Government level targeting (Federal, Provincial, Municipal, School Board)
- Email count and call count tracking
- Public vs admin visibility (non-admins see only their own campaigns)
- Integration with email queue, representatives, and responses modules
- Cover photo support (URL-based)

    .replace(/^-+|-+$/g, '')      // Remove leading/trailing -
    .slice(0, 80);                // Max 80 chars
}

// Collision detection
async function resolveSlugCollision(slug: string, excludeId?: string): Promise<string> {
  let candidate = slug;
  let suffix = 2;

  while (true) {
    const existing = await prisma.campaign.findUnique({ where: { slug: candidate } });

## Service Functions

### campaignsService.findAll(filters, user)

List campaigns with role-based visibility.

**Visibility Logic:**

```typescript
// Admin users see all campaigns
// Non-admin users see only their own campaigns
const adminRoles: UserRole[] = [UserRole.SUPER_ADMIN, UserRole.INFLUENCE_ADMIN, UserRole.MAP_ADMIN];
if (user && !adminRoles.includes(user.role)) {
  where.createdByUserId = user.id;
}
```

---

### campaignsService.create(data, user)

Create campaign with auto-generated slug and creator tracking.

**Creator Tracking:**

```typescript
const campaign = await prisma.campaign.create({
  data: {
    ...data,
    slug: await resolveSlugCollision(generateSlug(data.title)),
    createdByUserId: user.id,
    createdByUserEmail: user.email,
    createdByUserName: user.name || null,
  },
  select: campaignSelect,
});
```

---

### campaignsService.update(id, data)

Update campaign. Regenerates slug if title changes.

**Slug Regeneration:**

```typescript
if (data.title) {
  const newSlug = generateSlug(data.title);
  updateData.slug = await resolveSlugCollision(newSlug, id);
}
```

---

## Validation Schemas

### Create Campaign Schema

```typescript
export const createCampaignSchema = z.object({
  title: z.string().min(1, 'Title is required'),
  description: z.string().optional(),
  emailSubject: z.string().min(1, 'Email subject is required'),
  emailBody: z.string().min(1, 'Email body is required'),
  callToAction: z.string().optional(),
  status: z.nativeEnum(CampaignStatus).optional().default(CampaignStatus.DRAFT),
  targetGovernmentLevels: z.array(z.nativeEnum(GovernmentLevel)).optional().default([]),
  allowSmtpEmail: z.boolean().optional().default(true),
  allowMailtoLink: z.boolean().optional().default(true),
  collectUserInfo: z.boolean().optional().default(true),
  showEmailCount: z.boolean().optional().default(true),
  showCallCount: z.boolean().optional().default(true),
  allowEmailEditing: z.boolean().optional().default(false),
  allowCustomRecipients: z.boolean().optional().default(false),

## Code Examples

### Admin: Create Campaign

```typescript
import { api } from '@/lib/api';

const createCampaign = async () => {
  const { data } = await api.post('/api/campaigns', {
    title: 'Climate Action Now',
    emailSubject: 'Pass the Climate Emergency Bill',
    emailBody: 'Dear [Representative Name],\n\nI urge you to support immediate climate action...',
    targetGovernmentLevels: ['FEDERAL', 'PROVINCIAL'],
    status: 'DRAFT',
    showResponseWall: true,
    highlightCampaign: true,
  });

  console.log(`Campaign created: ${data.slug}`);
  return data;
};
```

### Public: List Active Campaigns

```typescript
import axios from 'axios';

const fetchActiveCampaigns = async () => {
  const { data } = await axios.get('/api/public/campaigns?highlighted=true');
  return data.campaigns;
};
```

### Admin: Update Campaign Status

```typescript
import { api } from '@/lib/api';

const publishCampaign = async (id: string) => {
  const { data } = await api.put(`/api/campaigns/${id}`, {
    status: 'ACTIVE',
  });

  message.success('Campaign published!');
  return data;
};
```

## Frontend Integration

The CampaignsPage component (`admin/src/pages/CampaignsPage.tsx`) provides:

- Paginated table with search and status filter
- Feature flag badges (SMTP, Response Wall, Highlighted, etc.)
- Create campaign modal with rich text editor (TinyMCE/Quill)
- Edit campaign modal (pre-populated form)
- Delete confirmation modal
- Email count drawer (shows campaign email stats)
- Publish/archive actions (status toggle)

**State Management:**

```typescript
const [campaigns, setCampaigns] = useState<Campaign[]>([]);
const [pagination, setPagination] = useState({ page: 1, limit: 20, total: 0 });
const [filters, setFilters] = useState({ search: '', status: null });
```
