Day 3 of the 12 Days of Christmas: Real-Time Power with BoxLang + SocketBox 🎄
As BoxLang continues evolving into a modern, high-performance, JVM-based runtime, real-time communication becomes essential for the applications we all want to build: dashboards, collaboration tools, notifications, live feeds, multiplayer features, and more.
That’s where SocketBox steps in — the WebSocket upgrade listener built to work seamlessly with CommandBox and the BoxLang MiniServer. ⚡
Today, for Day 3, we’re highlighting how SocketBox supercharges BoxLang development by giving you fast, flexible, and framework-agnostic WebSocket capabilities.
🔌 What Is SocketBox?
SocketBox is a lightweight WebSocket listener library that runs inside:
- CommandBox Web Server
- BoxLang MiniServer
It isn't a separate server — instead, it upgrades a request on the same port.
This means:
- No extra infrastructure
- Real-time messages delivered through your existing BoxLang or CFML request pipeline
- Full access to cookies, headers, sessions, hostnames — all available through standard CGI variables 🧩
At the core, your app receives WebSocket messages through an internal request to:
/WebSocket.cfc?method=onProcess
You then build your logic inside a custom WebSocket.cfc (or .bx) by extending SocketBox’s classes.
💡 Why SocketBox Matters for BoxLang Developers
SocketBox gives BoxLang apps:
- Real-time capabilities
- Low-level control when needed
- Optional STOMP message routing when you need advanced messaging
- A unified WebSocket experience across Lucee, Adobe CF, and BoxLang
All using the same integration layer — making your WebSocket code portable across engines.
Fewer surprises. More consistency. ✨
🧱 Two Ways to Use SocketBox
SocketBox offers two modes depending on how advanced your real-time logic needs to be.
1️⃣ Core WebSocket Mode — Simple & Direct
This is the lightweight, low-level mode ideal when you want total control.
You get callbacks for:
onConnect( channel )
onClose( channel )
onMessage( message, channel )
And utilities like:
sendMessage( message, channel )
broadcastMessage( message )
getAllConnections()
Example: Ping-Pong Handler
function onMessage( required message, required channel ) {
if ( message == "Ping" ) {
sendMessage( "Pong", channel );
}
}
Perfect for custom logic, games, live alerts, or when you want to define your own protocol.
No magic — just raw power ⚡.
2️⃣ STOMP Broker Mode — Enterprise Messaging
When you need authentication, routing, topics, fanouts, wildcards, heartbeats, and subscriptions —
the STOMP mode is your friend.
Extend:
modules.socketbox.models.WebSocketSTOMP
This unlocks:
- 🔐 Authentication & authorization hooks
- 🧭 Topic routing, exchanges, subscription management
- 🫀 Heartbeats & reconnection logic
- 🧩 Server-side listeners
- 📦 JSON message handling
You can even configure your own message exchanges:
.direct.topic.fanout.distribution- Or custom CFC exchanges
The STOMP broker provides message semantics similar to modern messaging platforms but fully embedded inside CommandBox + BoxLang.
⚙️ Browser Usage Example
Core WS Example
<script>
const socket = new WebSocket('ws://localhost/ws');
socket.onopen = () => socket.send("Hello from the browser!");
socket.onmessage = e => console.log("Server:", e.data);
</script>
STOMP Example
import { Client } from '@stomp/stompjs';
const client = new Client({
brokerURL: 'ws://localhost/ws',
heartbeatIncoming: 10000,
heartbeatOutgoing: 10000
});
client.activate();
</script>
WebSockets are fully accessible for modern frontend stacks — React, Vue, Svelte, and even Alpine.js.
