|
||||||
|
- Build with `npm run build`
|
||||||
|
|
||||||
|
### Database
|
||||||
|
- Use managed PostgreSQL (AWS RDS, Railway, Supabase)
|
||||||
|
- Run migrations before deploying
|
||||||
|
|
||||||
|
## 🐛 Troubleshooting
|
||||||
|
|
||||||
|
### Database connection error
|
||||||
|

|
||||||
|
- Verify DATABASE_URL is correct
|
||||||
|
- Run migrations: `npm run migrate`
|
||||||
|
|
||||||
|
### Frontend can't connect to backend
|
||||||
|
- Check API_URL in .env.local
|
||||||
|
- Ensure backend is running
|
||||||
|
- Check CORS settings
|
||||||
|
|
||||||
|
### Email alerts not working
|
||||||
|
- Configure SMTP settings in backend .env
|
||||||
|
- For development, use a service like Mailtrap
|
||||||
|
- For production, use SendGrid or similar

## Analytics & Insights (Future Feature)
|
||||||
|
|
||||||
|
### Personal Analytics Dashboard
|
||||||
|
1. User navigates to "Insights"
|
||||||
|
2. User sees:
|
||||||
|
- Total monitors
|
||||||
|
- Changes detected this month
|
||||||
|
- Most active monitors
|
||||||
|
- Alert response rate
|
||||||
|
3. User can filter by date range
|
||||||
|
4. User exports report
|
||||||
|
|
||||||
|
### Change Trends
|
||||||
|
1. User views monitor details
|
||||||
|
2. User sees "Trends" tab
|
||||||
|
3. Graph shows frequency of changes over time
|
||||||
|
4. User identifies patterns (e.g., "Changes every Monday")
|
||||||
|
5. User adjusts check frequency accordingly

# Website Change Detection Monitor - Claude Context
|
||||||
|
|
||||||
|
## Project Overview
|
||||||
|
|
||||||
|
This is a **Website Change Detection Monitor SaaS** application. The core value proposition is helping users track changes on web pages they care about, with intelligent noise filtering to ensure only meaningful changes trigger alerts.
|
||||||
|
|
||||||
|
**Tagline**: "I watch pages so you don't have to"
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Key Differentiators
|
||||||
|
|
||||||
|
1. **Smart Noise Filtering**: Unlike competitors, we automatically filter out cookie banners, timestamps, rotating ads, and other irrelevant changes
|
||||||
|
2. **Keyword-Based Alerts**: Users can be notified when specific words/phrases appear or disappear (e.g., "sold out", "hiring", "$99")
|
||||||
|
3. **Simple but Powerful**: Easy enough for non-technical users, powerful enough for professionals
|
||||||
|
4. **SEO-Optimized Market**: Tons of long-tail keywords (e.g., "monitor job postings", "track competitor prices")
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## Architecture Overview
|
||||||
|
|
||||||

// Text diff for detailed comparison
|
||||||
|
const diff = diffLines(previousText, currentText)
|
||||||
|
const changePercentage = (changedLines / totalLines) * 100
|
||||||
|
|
||||||
|
// Severity calculation
|
||||||
|
const severity =
|
||||||
|
changePercentage > 50 ? 'major' :
|
||||||
|
changePercentage > 10 ? 'medium' : 'minor'
|
||||||
|
```
|
||||||
|
|
||||||
|
### Noise Filtering
|
||||||
|
```typescript
|
||||||
|
// Remove common noise patterns
|
||||||
|
function filterNoise(html: string): string {
|
||||||
|
// Remove timestamps
|
||||||
|
html = html.replace(/\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}/g, '')
|
||||||
|
|
||||||
|
// Remove cookie banners (common selectors)
|
||||||
|
const noisySelectors = [
|
||||||
|
'.cookie-banner',
|
||||||
|
'#cookie-notice',
|
||||||
|
'[class*="consent"]',
|
||||||
|
// ... more patterns
|
||||||
|
]
|
||||||
|
|
||||||
|
// Parse and remove elements
|
||||||
|
const $ = cheerio.load(html)
|
||||||
|
noisySelectors.forEach(sel => $(sel).remove())
|
||||||
|
|
||||||
|
return $.html()
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Keyword Detection
|
||||||
|
```typescript
|
||||||
|
function checkKeywords(
|
||||||
|
previousText: string,
|
||||||
|
currentText: string,
|
||||||
|
rules: KeywordRule[]
|
||||||
|
): KeywordMatch[] {
|
||||||
|
const matches = []
|
||||||
|
|
||||||
|
for (const rule of rules) {
|
||||||
|
const prevMatch = previousText.includes(rule.keyword)
|
||||||
|
const currMatch = currentText.includes(rule.keyword)
|
||||||
|
|
||||||
|
if (rule.type === 'appears' && !prevMatch && currMatch) {
|
||||||
|
matches.push({ rule, type: 'appeared' })
|
||||||
|
}
|
||||||
|
if (rule.type === 'disappears' && prevMatch && !currMatch) {
|
||||||
|
matches.push({ rule, type: 'disappeared' })
|
||||||
|
}
|
||||||
|
|
||||||
|
// Count logic...
|
||||||
|
}
|
||||||
|
|
||||||
|
return matches
|
||||||
|
}
|
||||||
|
```

## Development Guidelines
|
||||||
|
|
||||||
|
### When Working on This Project
|
||||||
|
|
||||||
|
1. **Prioritize MVP**: Focus on core features before adding complexity
|
||||||
|
2. **Performance matters**: Diffing and fetching should be fast (<2s)
|
||||||
|
3. **Noise reduction is key**: This is our competitive advantage
|
||||||
|
4. **User feedback loop**: Build in ways to learn from false positives
|
||||||
|
5. **Security first**: Never store credentials in plain text, sanitize all URLs
|
||||||
|
|
||||||
|
### Code Style
|
||||||
|
|
||||||
|
- Use TypeScript strict mode
|
||||||
|
- Write unit tests for core algorithms (differ, filter, keyword)
|
||||||
|
- Use async/await, avoid callbacks
|
||||||
|
- Prefer functional programming patterns
|
||||||
|
- Comment complex logic, especially regex patterns
|
||||||
|
|
||||||
|
### API Design Principles
|
||||||
|
|
||||||
|
- RESTful endpoints
|
||||||
|
- Use proper HTTP status codes
|
||||||
|
- Return consistent error format:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"error": "monitor_not_found",
|
||||||
|
"message": "Monitor with id 123 not found",
|
||||||
|
"details": {}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
- Paginate list endpoints (monitors, snapshots, alerts)
|
||||||
|
- Version API if breaking changes needed (/v1/monitors)
|
||||||
|
|

|
## Key User Flows to Support
|
||||||
|
|
||||||
|
When building features, always consider these primary use cases:
|
||||||
|
|
||||||
|
1. **Job seeker monitoring career pages** (most common)
|
||||||
|
- Needs: Fast frequency (5 min), keyword alerts, instant notifications
|
||||||
|
|
||||||
|
2. **Price tracking for e-commerce** (high value)
|
||||||
|
- Needs: Element selection, numeric comparison, reliable alerts
|
||||||
|
|
||||||
|
3. **Competitor monitoring** (B2B focus)
|
||||||
|
- Needs: Multiple monitors, digest mode, AI summaries
|
||||||
|
|
||||||
|
4. **Stock/availability tracking** (urgent)
|
||||||
|
- Needs: Fastest frequency (1 min), SMS alerts, auto-pause
|
||||||
|
|
||||||
|
5. **Policy/regulation monitoring** (professional)
|
||||||
|
- Needs: Long-term history, team sharing, AI summaries
|
||||||
|
|

## Integration Points
|
||||||
|
|
||||||
|
### Email Service (SendGrid/Postmark)
|
||||||
|
```typescript
|
||||||
|
async function sendChangeAlert(monitor: Monitor, snapshot: Snapshot) {
|
||||||
|
const diffUrl = `https://app.example.com/monitors/${monitor.id}/diff/${snapshot.id}`
|
||||||
|
|
||||||
|
await emailService.send({
|
||||||
|
to: monitor.user.email,
|
||||||
|
subject: `Change detected: ${monitor.name}`,
|
||||||
|
template: 'change-alert',
|
||||||
|
data: {
|
||||||
|
monitorName: monitor.name,
|
||||||
|
url: monitor.url,
|
||||||
|
timestamp: snapshot.createdAt,
|
||||||
|
diffUrl,
|
||||||
|
changePercentage: snapshot.changePercentage
|
||||||
|
}
|
||||||
|
})
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Stripe Billing
|
||||||
|
```typescript
|
||||||
|
async function handleSubscription(userId: string, plan: string) {
|
||||||
|
const user = await db.users.findById(userId)
|
||||||
|
|
||||||
|
// Create or update subscription
|
||||||
|
const subscription = await stripe.subscriptions.create({
|
||||||
|
customer: user.stripeCustomerId,
|
||||||
|
items: [{ price: PRICE_IDS[plan] }]
|
||||||
|
})
|
||||||
|
|
||||||
|
// Update user plan
|
||||||
|
await db.users.update(userId, {
|
||||||
|
plan,
|
||||||
|
subscriptionId: subscription.id
|
||||||
|
})
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Job Queue (Bull)
|
||||||
|
```typescript
|
||||||
|
// Schedule monitor checks
|
||||||
|
async function scheduleMonitor(monitor: Monitor) {
|
||||||
|
await monitorQueue.add(
|
||||||
|
'check-monitor',
|
||||||
|
{ monitorId: monitor.id },
|
||||||
|
{
|
||||||
|
repeat: {
|
||||||
|
every: monitor.frequency * 60 * 1000 // convert to ms
|
||||||
|
},
|
||||||
|
jobId: `monitor-${monitor.id}`
|
||||||
|
}
|
||||||
|
)
|
||||||
|
}
|
||||||
|
|
||||||
|
// Process checks
|
||||||
|
monitorQueue.process('check-monitor', async (job) => {
|
||||||
|
const { monitorId } = job.data
|
||||||
|
await checkMonitor(monitorId)
|
||||||
|
})
|
||||||
|
```

|
||||||
|
|
||||||
|
## Troubleshooting Common Issues
|
||||||
|
|
||||||
|
### "Monitor keeps triggering false alerts"
|
||||||
|
- Check if noise filtering is working
|
||||||
|
- Review ignore rules for the monitor
|
||||||
|
- Look at diff to identify changing element
|
||||||
|
- Add custom ignore rule for that element
|
||||||
|
|
||||||
|
### "Some pages aren't being monitored correctly"
|
||||||
|
- Check if page requires JavaScript rendering
|
||||||
|
- Try enabling headless browser mode
|
||||||
|
- Check if page requires authentication
|
||||||
|
- Look for CAPTCHA or bot detection
|
||||||
|
|
||||||
|
### "Alerts aren't being delivered"
|
||||||
|
- Check email service status
|
||||||
|
- Verify email isn't going to spam
|
||||||
|
- Check alert queue for errors
|
||||||
|
- Verify user's alert settings
|
||||||
|
|
||||||
|
### "System is slow/overloaded"
|
||||||
|
- Check Redis queue health
|
||||||
|
- Look for monitors with very high frequency
|
||||||
|
- Check database query performance
|
||||||
|
- Consider scaling workers horizontally
|
||||||
|
|

## Notes for Claude
|
||||||
|
|
||||||
|
When working on this project:
|
||||||
|
|
||||||
|
1. **Always reference these docs**: spec.md, task.md, actions.md, and this file
|
||||||
|
2. **MVP mindset**: Implement the simplest solution that works first
|
||||||
|
3. **User-centric**: Consider the user workflows in actions.md when building features
|
||||||
|
4. **Security-conscious**: Validate URLs, sanitize inputs, encrypt sensitive data
|
||||||
|
5. **Performance-aware**: Optimize for speed, especially diff calculation
|
||||||
|
6. **Ask clarifying questions**: If requirements are ambiguous, ask before implementing
|
||||||
|
7. **Test as you go**: Write tests for core functionality
|
||||||
|
8. **Document decisions**: Update these docs when making architectural decisions
|
||||||
|
|
||||||
|
### Common Questions & Answers
|
||||||
|
|
||||||
|
**Q: Should we support authenticated pages in MVP?**
|
||||||
|
A: No, save for V2. Focus on public pages first.
|
||||||
|
|
||||||
|
**Q: What diff library should we use?**
|
||||||
|
A: `diff` (npm) or `jsdiff` for JavaScript, `difflib` for Python.
|
||||||
|
|
||||||
|
**Q: How do we handle CAPTCHA?**
|
||||||
|
A: For MVP, just alert the user. For V2, consider residential proxies or browser fingerprinting.
|
||||||
|
|
||||||
|
**Q: Should we store full HTML or just text?**
|
||||||
|
A: Store both: full HTML for accuracy, extracted text for diffing performance.
|
||||||
|
|
||||||
|
**Q: What's the minimum viable frequency?**
|
||||||
|
A: 5 minutes for paid users, 1 hour for free tier.

# Website Change Detection Monitor - Technical Specification
|
||||||
|
|
||||||
|
## Product Overview
|
||||||
|
|
||||||
|
A SaaS platform that monitors web pages for changes and alerts users when meaningful updates occur. The core value proposition is "signal over noise" - detecting real changes while filtering out irrelevant updates.
|
||||||
|
|
||||||
|
## Core Value Propositions
|
||||||
|
|
||||||
|
- **Easy to understand**: "I watch pages so you don't have to"
|
||||||
|
- **Smart filtering**: Automatically ignores timestamps, cookie banners, and noise
|
||||||
|
- **Keyword intelligence**: Alert on specific content appearing/disappearing
|
||||||
|
- **SEO-friendly**: Captures long-tail keywords (e.g., "monitor job posting changes")
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|

|
||||||
|
- Text diff (character/line level differences)
|
||||||
|
- **Storage**: Last 5-10 snapshots per URL
|
||||||
|
|
||||||
|
#### 2. Alert System
