Server Networking (network-server)

This document explains the network-server package implementation and the APIs used from server-side code.

Overview

The server listens on configured ports and accepts client connections. A single server process can accept many clients, and typical responsibilities in a game are:

Accept reliable control messages from clients over the TCP/WebSocket channel.
Optionally establish RTCPeerConnections via WebSocket signaling to receive unreliable, unordered data channels for low-latency state updates.

Example

It works the same with UDP:

// Send everybody a JSON-encoded packet
network.tcp.sendToEverybody(new TextEncoder().encode(JSON.stringify({ type: "are you here" })));

// Check connected clients
const connectedClients = getConnectedClients();

// Receive all packets
const allPackets = network.tcp.getReceivedPackets();

// Get first client packets
const firstClientPackets = map.get(connectedClients[0]);

// Decode packets if encoded as JSON
const decodedPackets = firstClientPackets.map((packet) => {
  return JSON.parse(new TextDecoder().decode(packet));
});

Notes

See Network Server API for the full list of available functions.
