## Using the React Components

### Price Comparison Component

```tsx
import { HandbagCompareOffers } from "@/components/HandbagCompareOffers";

const offers = [
  {
    id: "1",
    merchantName: "Fashionphile",
    condition: "used",
    price: 12500,
    currency: "USD",
    url: "https://fashionphile.com/item/123",
    label: "Certified Authentic",
  },
  // ... more real offers from RSS data
];

<HandbagCompareOffers
  brand="Hermès"
  modelName="Birkin 30"
  offers={offers}
  onOfferClick={(offer) => {
    // Track click, add affiliate code, etc.
    console.log("User clicked:", offer);
  }}
/>
```

### Historical Price Chart

```tsx
import { HandbagPriceChart } from "@/components/HandbagPriceChart";
import type { MerchantPriceSeries } from "@/types/priceHistory";

const series: MerchantPriceSeries[] = [
  {
    merchantName: "Fashionphile",
    merchantId: "fashionphile",
    condition: "used",
    dataPoints: [
      { date: "2025-11-01", price: 12800, inStock: true },
      { date: "2025-11-02", price: 12750, inStock: true },
      // ... real historical data from snapshots
    ],
  },
  // ... more merchants
];

<HandbagPriceChart
  brand="Hermès"
  model="Birkin 30"
  series={series}
  currency="USD"
/>
```

---

## Affiliate Signup Automation

### Pre-configured Merchants

```bash
# Fashionphile
npm run affiliates:signup fashionphile

# Rebag
npm run affiliates:signup rebag

# The RealReal
npm run affiliates:signup therealreal
```

This will:
1. Launch Chrome browser (non-headless)
2. Navigate to signup page
3. Pre-fill your business information
4. Highlight submit button
5. Wait for you to review and submit manually

### Adding New Merchant Configs

Edit `scripts/handbagAffiliateSignup.ts`:

```typescript
const merchantConfigs = {
  yourmerchant: {
    signupUrl: "https://yourmerchant.com/affiliates",
    selectors: {
      name: 'input[name="contact_name"]',
      email: 'input[id="email"]',
      company: 'input[name="company"]',
      website: 'input[name="site_url"]',
      description: 'textarea#description',
      submitButton: 'button[type="submit"]',
    },
  },
};
```

## Finding RSS Feeds

Most luxury retailers don't prominently advertise RSS feeds. Here's how to find them:

### 1. Check Page Source

```bash
curl -s https://fashionphile.com | grep -i 'rss\|atom\|feed'
```

Look for:
```html
<link rel="alternate" type="application/rss+xml" href="/feed.xml" />
```

### 2. Try Common URLs

- `/feed`
- `/rss`
- `/atom.xml`
- `/blog/feed`
- `/news/rss`

### 3. Use Browser Tools

Chrome extensions:
- RSS Feed Finder
- RSS Subscription Extension

### 4. Update Config

Edit `data/handbag_rss_sources.json`:

```json
{
  "id": "new-merchant-feed",
  "name": "New Merchant – Handbags",
  "siteDomain": "newmerchant.com",
  "feedUrl": "https://newmerchant.com/handbags/feed",
  "category": "resale",
  "active": true,
  "notes": "Found via page source inspection"
}
```

## Arbitrage Detection (Coming Soon)

The system is designed to detect arbitrage opportunities:

1. **RSS polling** finds new listings
2. **Price snapshots** track historical data
3. **Analysis script** compares against median prices
4. **Alerts** flag listings significantly under market

Example implementation in `scripts/snapshotPrices.ts`:

```typescript
if (item.price && item.price < medianPrice * 0.85) {
  console.log(`🚨 ARBITRAGE: ${item.title}`);
  console.log(`   Listed: $${item.price}, Median: $${medianPrice}`);
  // Send email, Slack notification, etc.
}
```

---

## Monitoring & Logs

### View Logs

```bash
# RSS polling log
tail -f /var/log/handbag-auth/rss-poll.log

# Price snapshot log
tail -f /var/log/handbag-auth/price-snapshot.log
```

### Check Cron Jobs

```bash
# View schedule
crontab -l

# Edit cron jobs
crontab -e
```

### Remove Cron Jobs

```bash
crontab -e
# Delete lines containing 'handbag-rss-poll' and 'handbag-price-snapshot'
```

## Integration with Shopify/Database

To connect this system with your handbag database:

### 1. Match RSS Items to Products

```typescript
// In scripts/pollHandbagRss.ts
import { PrismaClient } from "@prisma/client";
const prisma = new PrismaClient();

async function matchRssItemToProduct(item: HandbagFeedItem) {
  // Search database by brand + model
  const product = await prisma.handbag.findFirst({
    where: {
      brand: { contains: item.brand, mode: "insensitive" },
      model: { contains: extractModel(item.title), mode: "insensitive" },
    },
  });

  if (product) {
    // Link RSS item to product
    await prisma.externalListing.create({
      data: {
        handbagId: product.id,
        source: item.sourceId,
        price: item.price,
        url: item.link,
        condition: item.condition,
      },
    });
  }
}
```

### 2. Generate Affiliate Links

```typescript
function addAffiliateCode(url: string, merchantId: string): string {
  const affiliateCodes = {
    "fashionphile": "?aff=YOURCODE",
    "rebag": "?ref=YOURCODE",
    "therealreal": "?sid=YOURCODE",
  };

  const code = affiliateCodes[merchantId] || "";
  return url + code;
}
```

### 3. Display on Product Pages

Use the React components to show:
- Current offers from multiple merchants
- Historical price chart
- Best price badge
- Affiliate-tracked links

## TypeScript Types

All types are strongly typed for safety:

```typescript
// RSS item from feed
interface HandbagFeedItem {
  id: string;
  sourceId: string;
  title: string;
  link: string;
  brand?: string;
  model?: string;
  price?: number;
  condition?: "new" | "used" | "unknown";
}

// Price snapshot (daily record)
interface PriceSnapshot {
  id: string;
  handbagId: string;
  merchantName: string;
  price: number;
  snapshotDate: string;  // "2025-11-15"
  inStock: boolean;
}

// Affiliate program
interface HandbagAffiliateProgram {
  id: string;
  name: string;
  domain: string;
  merchantType: "brand" | "retailer" | "reseller" | "auction";
  commissionStructure?: string;
}
```

---

## Next Steps

1. **Verify RSS Feed URLs**
   - The current configs have placeholder URLs
   - Use the techniques above to find real feeds
   - Update `data/handbag_rss_sources.json`

2. **Run Initial Collection**
   ```bash
   npm run poll-rss
   npm run price-snapshot
   ```

3. **Set Up Cron Jobs**
   ```bash
   ./scripts/setup-cron.sh
   ```

4. **Apply for Affiliate Programs**
   ```bash
   npm run affiliates:signup fashionphile
   # Repeat for other merchants
   ```

5. **Integrate with Product Database**
   - Match RSS items to your handbag records
   - Store external listings
   - Generate affiliate links

6. **Build Product Pages**
   - Use `HandbagCompareOffers` to show current prices
   - Use `HandbagPriceChart` to show historical trends
   - Add "Buy Now" buttons with affiliate links
