# Pool The Pool class manages a collection of relay connections, providing a centralized way to track and reuse connections across your application. ## Overview - Creates and caches connections - Ensures single connection per relay - Handles cleanup of unused connections - Provides connection lookup ## Usage ```typescript import {Pool} from '@welshman/net' // Create pool const pool = new Pool() // Get or create connection const connection = pool.get("wss://relay.example.com") // Check if relay is in pool if (pool.has("wss://relay.example.com")) { // Use existing connection } // Remove connection pool.remove("wss://relay.example.com") // Clear all connections pool.clear() ``` The Pool is typically used internally by the router and executor, but can be used directly for custom connection management. It ensures efficient connection reuse across your application.
