Relay

The relayTransport() helper forwards native Transport<RPCMessage> traffic between two endpoints. The relay does not need to know the exposed API shape.

relay.ts

import { relayTransport } from "kkrpc/relay"
import { nodeStdioTransport } from "kkrpc/stdio"
import { webSocketTransport } from "kkrpc/ws"

const relay = relayTransport(
  webSocketTransport(socket),
  nodeStdioTransport({ readable: child.stdout, writable: child.stdin })
)

// Later, when shutting down:
relay.dispose()

Use a relay when one process should act as a transparent bridge between two already-created transports.
