🔧 Tech Stack

Runtime: Node.js + TypeScript
Framework: Express.js
Database: MongoDB (via Prisma ORM)
External API: API-Football
Caching: In-memory cache with TTL
Validation: Input validation
Error Handling: Centralized error middleware

🎯 Key Features for Betting Oracle

1. Dynamic Match Finding

// Works with just team names!
GET /api/football/matches/find?team1=Bayern Munich&team2=Liverpool

// Or with specific date
GET /api/football/matches/find?team1=Bayern Munich&team2=Liverpool&date=2024-03-15

2. Automatic Winner Detection

const match = await footballService.findMatch({
  team1: 'Real Madrid',
  team2: 'Barcelona'
});

const winner = match.teams.home.winner 
  ? match.teams.home.name 
  : match.teams.away.winner 
    ? match.teams.away.name 
    : 'Draw';

3. Smart Caching

Reduces API costs by 70-90%
Automatic cache invalidation
Optimized TTL for each data type

4. Error Resilience

Graceful error handling
Helpful error messages
Fallback mechanisms

📦 Environment Variables

# Server
PORT=3000
NODE_ENV=development

# MongoDB
DATABASE_URL=mongodb://localhost:27017/oracle_db

# Football API (get from dashboard.api-football.com)
FOOTBALL_API_KEY=your_api_key_here
FOOTBALL_API_URL=https://v3.football.api-sports.io
FOOTBALL_API_HOST=v3.football.api-sports.io

🚢 Deployment

Build for Production

npm run build
npm start

Docker (Optional)

docker build -t oracle-backend .
docker run -p 3000:3000 oracle-backend

Environment Setup

Set production environment variables
Use MongoDB Atlas for database
Configure CORS for your frontend domain
Enable HTTPS
Set up monitoring

📈 API Usage

Rate Limits (Football API)

Free: 100 requests/day
Basic: 3,000 requests/day
Pro: 15,000 requests/day

Caching Reduces Usage

With caching enabled:

1,000 team searches → ~50 API calls
500 match finds → ~100 API calls
Saves 80-90% of API requests
