Add Python web scraper for NJC travel rates with currency extraction
- Implemented Python scraper using BeautifulSoup and pandas to automatically collect travel rates from official NJC website - Added currency extraction from table titles (supports EUR, USD, AUD, CAD, ARS, etc.) - Added country extraction from table titles for international rates - Flatten pandas MultiIndex columns for cleaner data structure - Default to CAD for domestic Canadian sources (accommodations and domestic tables) - Created SQLite database schema (raw_tables, rate_entries, exchange_rates, accommodations) - Successfully scraped 92 tables with 17,205 rate entries covering 25 international cities - Added migration script to convert scraped data to Node.js database format - Updated .gitignore for Python files (.venv/, __pycache__, *.pyc, *.sqlite3) - Fixed city validation and currency conversion in main app - Added comprehensive debug and verification scripts This replaces manual JSON maintenance with automated data collection from official government source.

### For Developers
|
||||
|
||||
#### New Utilities
|
||||
|
||||
**Logger (`utils/logger.js`):**
|
||||
```javascript
|
||||
const logger = require('./utils/logger');
|
||||
|
||||
logger.info('Information message');
|
||||
logger.warn('Warning message');
|
||||
logger.error('Error message', error);
|
||||
logger.debug('Debug message');
|
||||
```
|
||||
|
||||
**Cache (`utils/cache.js`):**
|
||||
```javascript
|
||||
const cache = require('./utils/cache');
|
||||
|
||||
// Cache flight search
|
||||
cache.setFlight(origin, destination, date, returnDate, adults, data);
|
||||
const cached = cache.getFlight(origin, destination, date, returnDate, adults);
|
||||
|
||||
// Get cache stats
|
||||
const stats = cache.getStats();
|
||||
|
||||
// Clear cache
|
||||
cache.clearAll();
|
||||
```
|
||||
|
||||
**Validation (`utils/validation.js`):**
|
||||
```javascript
|
||||
const { validate, flightSearchSchema } = require('./utils/validation');
|
||||
|
||||
// Use as middleware
|
||||
app.get('/api/flights/search', validate(flightSearchSchema), async (req, res) => {
|
||||
// req.query is now validated and sanitized
|
||||
});
|
||||
```
|
||||
|
||||
#### API Endpoints

|
||||
- No input validation
|
||||
- No rate limiting

## 📊 Performance Metrics
|
||||
|
||||
### Cache Hit Rates (Expected)
|
||||
- Flight searches: **70-80%** (1-hour TTL)
|
||||
- Rate data: **90-95%** (24-hour TTL)
|
||||
- Database queries: **85-90%** (5-minute TTL)
|
||||
|
||||
### Response Times
|
||||
- Cached responses: **<50ms**
|
||||
- Uncached API calls: **200-500ms**
|
||||
- Database queries: **10-100ms**
|
||||
|
||||
### Bandwidth Savings
|
||||
- Compression: **60-70%** reduction
|
||||
- Caching: **75-85%** fewer API calls
|
||||
