});

const Listing = mongoose.model('Listing', listingSchema);

// API endpoints
app.get('/listings', async (req, res) => {
  const listings = await Listing.find();
  res.json(listings);
});

// ... other endpoints

app.listen(port, () => {
  console.log(`Listing service listening on port ${port}`);
});
