@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

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

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
