# Quick Start Guide

## Prerequisites

- Docker and Docker Compose
- Go 1.21+
- Node.js 20+
- PostgreSQL 16+ (or use Docker)
- Elasticsearch/OpenSearch (or use Docker)

## Setup

1. **Clone and navigate to project**
   ```bash
   cd explorer-monorepo
   ```

2. **Configure environment**
   ```bash
   cp .env.example .env
   # Edit .env with your configuration
   ```

3. **Install dependencies**
   ```bash
   make install
   # Or manually:
   # cd backend && go mod download
   # cd ../frontend && npm install
   ```

4. **Start infrastructure**
   ```bash
   docker-compose -f deployment/docker-compose.yml up -d postgres elasticsearch redis
   ```

5. **Run migrations**
   ```bash
   cd backend
   go run database/migrations/migrate.go
   cd ..
   ```

6. **Check requirements**
   ```bash
   ./scripts/check-requirements.sh
   ```

7. **Start development services**
   ```bash
   ./scripts/run-dev.sh
   ```
   
   Note: Make sure you're in the `explorer-monorepo` directory when running scripts.

   Or manually:
   ```bash
   # Terminal 1: Indexer
   cd backend/indexer && go run main.go

   # Terminal 2: API
   cd backend/api/rest && go run main.go

   # Terminal 3: Frontend
   cd frontend && npm run dev
   ```

## Access

- **Frontend**: http://localhost:3000
- **API**: http://localhost:8080
- **API Gateway**: http://localhost:8081
- **Search Service**: http://localhost:8082

## Configuration

Edit `.env` file with your settings:

```env
# Database
DB_HOST=localhost
DB_PORT=5432
DB_USER=explorer
DB_PASSWORD=changeme
DB_NAME=explorer

# RPC
RPC_URL=http://localhost:8545
WS_URL=ws://localhost:8546
CHAIN_ID=138

# Search
SEARCH_URL=http://localhost:9200
```

## Next Steps

1. **Index blocks**: The indexer will start processing blocks automatically
2. **Browse explorer**: Visit http://localhost:3000 to see blocks and transactions
3. **Check API**: Test endpoints at http://localhost:8080/api/v1/blocks
4. **Review documentation**: See `docs/specs/` for detailed specifications

## Troubleshooting

### Database connection errors
- Ensure PostgreSQL is running: `docker ps`
- Check connection string in `.env`
- Verify migrations ran successfully

### Indexer not processing blocks
- Check RPC URL is correct and accessible
- Verify database connection
- Check logs for errors

### Frontend not loading
- Ensure API server is running
- Check API_URL in frontend `.env`
- Verify CORS settings

## Production Deployment

See `deployment/` directory for:
- Kubernetes manifests
- Docker Compose files
- CI/CD configurations
