# 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
|
|
- `makeSocket(url)` - Creates a Socket for the given URL, using `PoolOptions.makeSocket` if provided, otherwise applies `defaultSocketPolicies`
|
|
- `subscribe(callback)` - Subscribes to new socket creation events
|
|
- `remove(url)` - Removes and cleans up a socket
|
|
- `clear()` - Removes all sockets from the pool
|
|
|
|
## Example
|
|
|
|
```typescript
|
|
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")
|
|
```
