# @stock-bot/config
A configuration management library for the Stock Bot trading platform.
## Overview
This library provides a centralized way to manage configurations across all Stock Bot microservices and components. It includes:
- Environment-based configuration loading
- Strong TypeScript typing and validation using Zod
- Default configurations for services
- Environment variable parsing helpers
- Service-specific configuration modules
## Usage
### Basic Usage
```typescript
import { databaseConfig, dataProviderConfigs, riskConfig } from '@stock-bot/config';
// Access database configuration
const dragonflyHost = databaseConfig.dragonfly.host;
// Access data provider configuration
const alpacaApiKey = dataProviderConfigs.providers.find(p => p.name === 'alpaca')?.apiKey;
// Access risk configuration
const maxPositionSize = riskConfig.maxPositionSize;
```
### Service-Specific Configuration
```typescript
import { marketDataGatewayConfig, riskGuardianConfig } from '@stock-bot/config';
// Access Market Data Gateway configuration
const websocketPath = marketDataGatewayConfig.websocket.path;
// Access Risk Guardian configuration
const preTradeValidation = riskGuardianConfig.riskChecks.preTradeValidation;
```
### Environment Variables
The library automatically loads environment variables from `.env` files. You can create environment-specific files:
- `.env` - Base environment variables
- `.env.development` - Development-specific variables
- `.env.production` - Production-specific variables
- `.env.local` - Local overrides (not to be committed to git)
## Configuration Modules
### Core Configuration
- `Environment` - Enum for different environments
- `loadEnvVariables()` - Load environment variables from .env files
- `getEnvironment()` - Get the current environment
- `validateConfig()` - Validate configuration with Zod schema
### Database Configuration
- `databaseConfig` - Database connection settings (Dragonfly, QuestDB, MongoDB, PostgreSQL)
### Data Provider Configuration
- `dataProviderConfigs` - Settings for market data providers
### Risk Configuration
- `riskConfig` - Risk management parameters (max drawdown, position size, etc.)
### Service-Specific Configuration
- `marketDataGatewayConfig` - Configs for the Market Data Gateway service
- `riskGuardianConfig` - Configs for the Risk Guardian service
## Extending
To add a new service configuration:
1. Create a new file in `src/services/`
2. Define a Zod schema for validation
3. Create loading and default configuration functions
4. Export from `src/services/index.ts`
5. The new configuration will be automatically available from the main package
## Development
```bash
# Install dependencies
bun install
# Run tests
bun test
# Type check
