# 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 `RTCPeerConnection`s via WebSocket signaling to receive unreliable, unordered data channels for low-latency state updates.

## Example

It works the same with UDP:

```javascript theme={null}
// 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](network-server-api) for the full list of available functions.
* For packet framing and terminator semantics, see [Packet Framing](packet-framing).
