+# Library Standards and Patterns
+
+This document defines the standardized patterns for all libraries in the @stock-bot ecosystem.
+
+## Export Patterns
+
+### Standard: Named Exports Only
+
+All libraries should use **named exports only**. Default exports have been removed for consistency and better tree-shaking.
+
+**Example:**
+```typescript
+// ✅ Good - Named exports
+export { createCache } from './cache';
+export type { CacheOptions } from './types';
+
+// ❌ Bad - Default export
+export default createCache;
+```
+
+## Initialization Patterns
+
+Libraries follow different initialization patterns based on their purpose:
+
+### 1. Singleton with Global State
+**Use for:** Global services that should have only one instance (config, logger)
+
+**Example:** Config library
+```typescript
+let configInstance: ConfigManager | null = null;
+
+export function initializeConfig(): AppConfig {
+  if (!configInstance) {
+    configInstance = new ConfigManager();
+  }
+  return configInstance.initialize();
+}
+
+export function getConfig(): AppConfig {
+  if (!configInstance) {
+    throw new Error('Config not initialized');
+  }
+  return configInstance.get();
+}
+```
+
+### 2. Factory with Registry
+**Use for:** Services that need instance reuse based on configuration (cache, logger instances)
+
+**Example:** Cache library
+```typescript
+const cacheInstances = new Map<string, CacheProvider>();
+
+export function createCache(options: CacheOptions): CacheProvider {
+  if (options.shared) {
+    const key = generateKey(options);
+    if (cacheInstances.has(key)) {
+      return cacheInstances.get(key)!;
+    }
+    const cache = new RedisCache(options);
+    cacheInstances.set(key, cache);
+    return cache;
+  }
+  return new RedisCache(options);
+}
+```
+
+### 3. Pure Factory Functions
+**Use for:** Services that need creation logic beyond simple instantiation
+
+**Example:** Event bus with configuration processing
+```typescript
+export function createEventBus(config: EventBusConfig): EventBus {
+  // Process config, set defaults, etc.
+  const processedConfig = { ...defaultConfig, ...config };
+  return new EventBus(processedConfig);
+}
+```
+
+**Note:** Simple instantiation doesn't need factories - use direct class instantiation or DI container.
+
+### 4. Direct Class Exports
+**Use for:** Simple utilities or services managed by DI container
+
+**Example:** MongoDB library
+```typescript
+export { MongoDBClient } from './client';
+// No factory function - let DI container handle instantiation
+```
+
+### 5. Singleton Classes
+**Use for:** Manager classes that coordinate multiple instances
+
+**Example:** QueueManager
+```typescript
+export class QueueManager {
+  private static instance: QueueManager | null = null;
+  
+  static initialize(config: QueueConfig): QueueManager {
+    if (!QueueManager.instance) {
+      QueueManager.instance = new QueueManager(config);
+    }
+    return QueueManager.instance;
+  }
+  
+  static getInstance(): QueueManager {
+    if (!QueueManager.instance) {
+      throw new Error('QueueManager not initialized');
+    }
+    return QueueManager.instance;
+  }
+}
+```
+
+## Pattern Selection Guide
+
+Choose the initialization pattern based on these criteria:
+
+| Pattern | When to Use | Examples |
+|---------|-------------|----------|
+| **Singleton with Global State** | - One instance per process<br>- Stateful configuration<br>- Process-wide settings | config, logger setup |
+| **Factory with Registry** | - Multiple instances with same config should share<br>- Connection pooling<br>- Resource optimization | cache, logger instances |
+| **Pure Factory** | - Complex initialization logic<br>- Configuration processing needed<br>- Defaults to apply | event bus (if needed) |
+| **Direct Class Export** | - DI container manages lifecycle<br>- Simple initialization<br>- No special setup needed | database clients (MongoDB, PostgreSQL, QuestDB), utilities |
+| **Singleton Class** | - Coordinates multiple resources<br>- Central management point<br>- Graceful shutdown needed | QueueManager, ConnectionManager |
+
+## Additional Standards
+
+### Error Handling
+- All libraries should throw descriptive errors
+- Consider creating custom error classes for domain-specific errors
+- Always include context in error messages
+
+### Configuration
+- Accept configuration through constructor/factory parameters
+- Validate configuration using Zod schemas
+- Provide sensible defaults where appropriate
+
+### Testing
+- All libraries must have unit tests
+- Use consistent test file naming: `*.test.ts`
+- Mock external dependencies
+
+### Documentation
+- Every library must have a README.md
+- Include usage examples
+- Document all public APIs with JSDoc
+
+### TypeScript
+- Export all public types
+- Use strict TypeScript settings
+- Avoid `any` types
+
+### Dependencies
+- Minimize external dependencies
+- Use exact versions for critical dependencies
+- Document peer dependencies clearly
