Market & Sell Page Fixes
Summary
Fixed critical issues preventing the Market page from loading items and completely rebuilt the Sell page to properly fetch Steam inventories via SteamAPIs.com.
Issues Fixed
1. Market Page - Not Loading Items
Problem:
- Market page showed infinite loading
- Items weren't being fetched from the database
- Loading state was using wrong property name
Root Causes:
- Incorrect loading property: MarketPage was checking
marketStore.loadinginstead ofmarketStore.isLoading - Vite proxy misconfiguration: The proxy was stripping
/apiprefix, causing routes to fail- Frontend sent:
/api/market/items - Proxy rewrote to:
/market/items - Backend expected:
/api/market/items
- Frontend sent:
Fixes:
- ✅ Changed
marketStore.loadingtomarketStore.isLoadingin MarketPage.vue - ✅ Removed the
rewritefunction from Vite proxy configuration - ✅ Backend routes now properly receive
/apiprefix
2. Sell Page - Loading Database Items Instead of Steam Inventory
Problem:
- Sell page was calling
/api/market/items(marketplace database) - Should be calling
/api/inventory/steam(user's Steam inventory) - No Steam trade URL validation
- No proper pricing integration

-
Pricing Endpoint:

Configuration Changes
Vite Proxy (frontend/vite.config.js)
Before:
proxy: {
"/api": {
target: "http://localhost:3000",
changeOrigin: true,
rewrite: (path) => {
const newPath = path.replace(/^\/api/, "");
console.log(`[Vite Proxy] ${path} -> ${newPath}`);
return newPath;
},
},
}
After:
proxy: {
"/api": {
target: "http://localhost:3000",
changeOrigin: true,
// Don't rewrite - backend expects /api prefix
},
}
Setup Requirements
1. Environment Variables
Add to .env file:
# Steam API Key (from steamapis.com)
STEAM_API_KEY=your_steamapis_key_here
2. Get Steam API Key
Option A: SteamAPIs.com (Recommended)
- Go to https://steamapis.com/
- Sign up for free account
- Get API key from dashboard
- Free tier: 100,000 requests/month
Option B: Steam Web API (Alternative)
- Go to https://steamcommunity.com/dev/apikey
- Register for API key
- Note: Lower rate limits, less reliable
3. User Setup
Users must:
- Login via Steam - Required for inventory access
- Make inventory public - Steam Privacy Settings → Game details & Inventory → Public
- Set Trade URL - Profile page → Steam Trade URL field
Trade URL Mechanic
Why It's Required
- TurboTrades needs to send Steam trade offers to users
- Trade URL is unique identifier for sending offers
- Without it, items cannot be transferred
- Required by Steam for bot trading
How It Works
-
User sets Trade URL in profile:
- Found at: https://steamcommunity.com/id/YOUR_ID/tradeoffers/privacy
- Format:
https://steamcommunity.com/tradeoffer/new/?partner=XXXXX&token=XXXXXXXX
-
Sell page validates Trade URL:
- Shows warning banner if not set
- Disables "Sell Selected Items" button
- Redirects to profile if user tries to sell
-
After item sale:
- Backend creates marketplace listing
- Credits user balance immediately
- User receives Steam trade offer (future: bot integration)
- Trade must be accepted to complete transfer
Future Implementation (Steam Bots)
To fully automate:
- Set up Steam bot account(s)
- Integrate steam-tradeoffer-manager package
- Send automatic trade offers when items sold
- Verify trade completion before final credit
- Handle trade errors and cancellations

Known Limitations
Current Pricing System
- Status: Placeholder algorithm
- Issue: Not using real market prices
- Impact: Prices are estimated, not accurate
- Solution: Integrate real pricing API (CSGOBackpack, Steam Market, etc.)
Trade Offers
- Status: Not implemented
- Issue: No Steam bot integration yet
- Impact: Users don't receive actual trade offers
- Solution: Implement steam-tradeoffer-manager and bot accounts
Inventory Caching
- Status: No caching
- Issue: Fetches inventory on every page load
- Impact: Slower load times, higher API usage
- Solution: Cache inventory for 5-10 minutes in Redis
Next Steps
Short Term
- Add STEAM_API_KEY to environment
- Test with real Steam account
- Verify inventory loading
- Test item selection and selling
Medium Term
- Integrate real pricing API
- Implement inventory caching
- Add rate limiting
- Improve error messages
Long Term
- Set up Steam bot accounts
- Implement trade offer automation
- Add trade status tracking
- Handle trade cancellations/errors
- Support multiple bots for scaling
