Pool

The Pool class manages a collection of websocket connections to relay servers, providing connection pooling and lifecycle management.

Classes

Pool

A connection pool that creates and manages Socket instances for different relay URLs.

Methods:

• static get() - Returns the singleton pool instance
• has(url) - Checks if a socket exists for the given URL
• get(url) - Gets or creates a socket for the given URL
• subscribe(callback) - Subscribes to new socket creation events
• remove(url) - Removes and cleans up a socket
• clear() - Removes all sockets from the pool

Functions

makeSocket(url, policies)

Creates a new Socket instance with the given URL and applies default policies.

Example

import {Pool} from "@welshman/net"

// Get the singleton - Pool can also be instantiated directly if you want multiple pools
const pool = Pool.get()

// Get a socket for a relay
const socket = pool.get("wss://relay.example.com")

// Subscribe to new socket creation
const unsubscribe = pool.subscribe((socket) => {
  console.log("New socket created:", socket.url)
})

// Clean up
pool.remove("wss://relay.example.com")
