Usage

Import the Service

import marketPriceService from "./services/marketPrice.js";

Get Single Price

// By exact market hash name
const price = await marketPriceService.getPrice(
  "AK-47 | Redline (Field-Tested)",
  "cs2"
);
console.log(price); // 12.50

Get Multiple Prices (Batch)

const names = [
  "AK-47 | Redline (Field-Tested)",
  "AWP | Asiimov (Field-Tested)",
  "M4A4 | Howl (Factory New)"
];

const priceMap = await marketPriceService.getPrices(names, "cs2");
console.log(priceMap);
// {
//   "AK-47 | Redline (Field-Tested)": 12.50,
//   "AWP | Asiimov (Field-Tested)": 95.00,
//   "M4A4 | Howl (Factory New)": 4500.00
// }

Get Full Item Data

const item = await marketPriceService.getItem(
  "AK-47 | Redline (Field-Tested)",
  "cs2"
);
console.log(item);
// {
//   name: "AK-47 | Redline (Field-Tested)",
//   game: "cs2",
//   price: 12.50,
//   image: "https://...",
//   borderColor: "#eb4b4b",

// }

Enrich Inventory with Prices

// When loading Steam inventory
const inventoryItems = [
  { market_hash_name: "AK-47 | Redline (Field-Tested)", ... },
  { market_hash_name: "AWP | Asiimov (Field-Tested)", ... }
];

const enriched = await marketPriceService.enrichInventory(
  inventoryItems,
  "cs2"
);

console.log(enriched[0]);
// {
//   market_hash_name: "AK-47 | Redline (Field-Tested)",
//   marketPrice: 12.50,
//   hasPriceData: true,
//   ...
// }

Search Items

// Search by name (partial match)
const results = await marketPriceService.search("AK-47", "cs2", 10);
console.log(results.length); // Up to 10 results

Get Suggested Price (with Markup)

// Get price with 10% markup
const suggested = await marketPriceService.getSuggestedPrice(
  "AK-47 | Redline (Field-Tested)",
  "cs2",
  1.10 // 10% markup
);
console.log(suggested); // 13.75

Get Top Priced Items

const topItems = await marketPriceService.getTopPriced("cs2", 10);
topItems.forEach((item, i) => {
  console.log(`${i + 1}. ${item.name}: $${item.price}`);
});

Get Items by Price Range

// Get items between $10 and $50
const items = await marketPriceService.getByPriceRange(10, 50, "cs2", 100);
console.log(`Found ${items.length} items`);

Commands

Import/Update All Prices

# Download latest prices from Steam API and import to database
node import-market-prices.js

# This will:
# 1. Fetch 29,602 CS2 items
# 2. Fetch 5,039 Rust items
# 3. Upsert into MongoDB (updates existing, inserts new)
# 4. Takes ~30-60 seconds

Check Status

# Check how many items are in database
node -e "import('./services/marketPrice.js').then(async s => {
  const cs2 = await s.default.getCount('cs2');
  const rust = await s.default.getCount('rust');
  console.log('CS2:', cs2);
  console.log('Rust:', rust);
  process.exit(0);
})"

Test Price Lookup

# Test looking up a specific item
node -e "import('./services/marketPrice.js').then(async s => {
  const price = await s.default.getPrice('AK-47 | Redline (Field-Tested)', 'cs2');
  console.log('Price:', price);
  process.exit(0);
})"

Integration Examples

Example 1: Sell Page Inventory Loading

// routes/inventory.js
import marketPriceService from "../services/marketPrice.js";

fastify.get("/inventory/:game", async (request, reply) => {
  const { game } = request.params;
  
  // Fetch from Steam API
  const steamInventory = await fetchSteamInventory(
    request.user.steamId,
    game
  );
  
  // Enrich with market prices
  const enrichedInventory = await marketPriceService.enrichInventory(
    steamInventory,
    game
  );
  
  return reply.send({
    success: true,
    items: enrichedInventory
  });
});

Example 2: Admin Panel Price Override

// routes/admin.js
fastify.put("/items/:id/price", async (request, reply) => {
  const { id } = request.params;
  const { price, marketHashName } = request.body;
  
  // Get suggested price from market data
  const marketPrice = await marketPriceService.getPrice(
    marketHashName,
    "cs2"
  );
  
  // Update item
  await Item.findByIdAndUpdate(id, {
    price: price,
    marketPrice: marketPrice,
    priceOverride: true
  });
  
  return reply.send({ success: true });
});

Example 3: Auto-Price New Listings

// When user lists item for sale
fastify.post("/sell", async (request, reply) => {
  const { assetId, game } = request.body;
  
  // Get item from inventory
  const inventoryItem = await getInventoryItem(assetId);
  
  // Get suggested price (with 5% markup)
  const suggestedPrice = await marketPriceService.getSuggestedPrice(
    inventoryItem.market_hash_name,
    game,
    1.05 // 5% markup
  );
  
  // Create listing
  const item = await Item.create({
    name: inventoryItem.market_hash_name,
    price: suggestedPrice,
    game: game,
    seller: request.user._id
  });
  
  return reply.send({
    success: true,
    item,
    suggestedPrice
  });
});

Price Types

The system uses the best available price from Steam API:

1. safe (preferred) - Most reliable price
2. median - Middle value price
3. mean - Average price
4. avg - Alternative average
5. latest - Most recent transaction price

---

Maintenance

Update Schedule

Recommended: Run weekly or bi-weekly

# Add to cron or Task Scheduler
# Every Sunday at 2 AM
0 2 * * 0 cd /path/to/TurboTrades && node import-market-prices.js

Check if Data is Outdated

const isOutdated = await marketPriceService.isOutdated("cs2", 168); // 7 days
if (isOutdated) {
  console.log("⚠️  Price data is older than 7 days - consider updating");
}

Get Last Update Time

const lastUpdate = await marketPriceService.getLastUpdate("cs2");
console.log(`Last updated: ${lastUpdate.toLocaleString()}`);

---

Performance

Query Performance

• ✅ Single lookup: < 1ms (indexed)
• ✅ Batch lookup (100 items): < 10ms (indexed)
• ✅ Search (regex): < 50ms
• ✅ Stats aggregation: < 100ms

Storage

• CS2: ~15MB (29,602 items)
• Rust: ~2.5MB (5,039 items)
• Total: ~17.5MB

---

Error Handling

All service methods return null or empty arrays on error:

const price = await marketPriceService.getPrice("Invalid Item", "cs2");
console.log(price); // null

const items = await marketPriceService.search("xyz", "cs2");
console.log(items); // []

Always check for null/empty:

const price = await marketPriceService.getPrice(itemName, game);
if (price === null) {
  console.log("Price not found - using fallback");
  price = 0.00;
}

---

API Comparison

Old Method (Live API Call)

// Slow: 500-2000ms per request
// Rate limited: 200 calls/minute
// Requires API key on every request
const price = await steamAPIsClient.getPrice(itemName);

New Method (Database Lookup)

// Fast: < 1ms per request
// No rate limits
// No API key needed
const price = await marketPriceService.getPrice(itemName, game);

Benefits:

• ✅ 500x faster
• ✅ No rate limits
• ✅ Works offline
• ✅ Batch lookups
• ✅ Full-text search
• ✅ Price statistics

---

Troubleshooting

No prices found

# Check if data exists
node -e "import('./services/marketPrice.js').then(async s => {
  const count = await s.default.getCount();
  console.log('Total items:', count);
  if (count === 0) {
    console.log('Run: node import-market-prices.js');
  }
  process.exit(0);
})"

Prices outdated

# Re-import latest prices
node import-market-prices.js

Item not found

The item name must match exactly as it appears in Steam market:

// ❌ Wrong
"AK-47 Redline FT"

// ✅ Correct
"AK-47 | Redline (Field-Tested)"

Use the search() function to find correct names:

const results = await marketPriceService.search("AK-47 Redline", "cs2");
console.log(results.map(r => r.name));

---

Best Practices

1. Always Specify Game

// ✅ Good - faster query
const price = await marketPriceService.getPrice(name, "cs2");

// ❌ Slower - searches all games
const price = await marketPriceService.getPrice(name);

2. Use Batch Lookups for Multiple Items

// ✅ Good - single query
const prices = await marketPriceService.getPrices(names, game);

// ❌ Bad - multiple queries
for (const name of names) {
  const price = await marketPriceService.getPrice(name, game);
}

3. Cache Frequently Accessed Prices

// In-memory cache for hot items
const priceCache = new Map();

async function getCachedPrice(name, game) {
  const key = `${game}:${name}`;
  if (priceCache.has(key)) {
    return priceCache.get(key);
  }
  
  const price = await marketPriceService.getPrice(name, game);
  priceCache.set(key, price);
  return price;
}

4. Handle Missing Prices Gracefully

const price = await marketPriceService.getPrice(name, game) || 0.00;
