# Quick Start Guide

## Prerequisites

1. Node.js 20+
2. PostgreSQL 14+ with TimescaleDB extension
3. Access to RPC endpoints for ChainID 138 and 651940

## Quick Setup (5 minutes)

### 1. Install Dependencies
```bash
cd smom-dbis-138/services/token-aggregation
npm install
```

### 2. Configure Environment
```bash
cp .env.example .env
# Edit .env with your values
```

Minimum required in `.env`:
```bash
DATABASE_URL=postgresql://user:password@localhost:5432/explorer_db
CHAIN_138_RPC_URL=https://rpc-http-pub.d-bis.org
CHAIN_651940_RPC_URL=https://mainnet-rpc.alltra.global
```

### 3. Run Database Migration
```bash
# Navigate to explorer backend and run migration
cd ../../explorer-monorepo/backend
# Run migration 0011_token_aggregation_schema.up.sql
```

### 4. Build and Start
```bash
cd ../../smom-dbis-138/services/token-aggregation
npm run build
npm start
```

### 5. Verify
```bash
# Health check
curl http://localhost:3000/health

# Test API
curl http://localhost:3000/api/v1/chains
```

## Docker Quick Start

```bash
# Build and run
docker-compose up -d

# View logs
docker-compose logs -f

# Stop
docker-compose down
```

## Development Mode

```bash
npm run dev
```

## API Examples

### Get token details
```bash
curl "http://localhost:3000/api/v1/tokens/0x93E66202A11B1772E55407B32B44e5Cd8eda7f22?chainId=138"
```

### Get token pools
```bash
curl "http://localhost:3000/api/v1/tokens/0x93E66202A11B1772E55407B32B44e5Cd8eda7f22/pools?chainId=138"
```

### Get OHLCV data
```bash
curl "http://localhost:3000/api/v1/tokens/0x93E66202A11B1772E55407B32B44e5Cd8eda7f22/ohlcv?chainId=138&interval=1h"
```

### Search tokens
```bash
curl "http://localhost:3000/api/v1/search?q=USDT&chainId=138"
```

## Troubleshooting

### Database Connection Issues
- Verify `DATABASE_URL` is correct
- Ensure PostgreSQL is running
- Check TimescaleDB extension is enabled

### RPC Connection Issues
- Test RPC endpoints manually
- Verify RPC URLs in `.env`

### Indexing Not Working
- Check logs for errors
- Verify DEX factory addresses are configured
- Ensure RPC endpoints have required APIs enabled

## Next Steps

1. Configure DEX factory addresses for your chains
2. (Optional) Add external API keys for enrichment
3. Monitor indexing progress in logs
4. Integrate with your frontend/explorer
