STOMP-WebSocket is a JavaScript library that implements the STOMP (Simple Text Oriented Messaging Protocol) over WebSocket. It allows web applications to communicate with message brokers using the STOMP protocol, enabling real-time messaging and pub/sub functionality in web browsers.

Pros

• Easy integration with existing STOMP message brokers
• Supports both browser and Node.js environments
• Lightweight and has minimal dependencies
• Provides a simple API for STOMP operations

Cons

• Limited active development (last update was in 2019)
• Lacks some advanced features found in newer messaging libraries
• Documentation could be more comprehensive
• May require additional setup for secure WebSocket connections (WSS)

Code Examples

1. Connecting to a STOMP broker:

const client = Stomp.client('ws://localhost:15674/ws');
client.connect({}, function(frame) {
    console.log('Connected: ' + frame);
});

2. Subscribing to a topic:

client.subscribe('/topic/messages', function(message) {
    console.log('Received message: ' + message.body);
});

3. Sending a message:

client.send('/queue/test', {priority: 9}, 'Hello, STOMP');

4. Disconnecting from the broker:

client.disconnect(function() {
    console.log('Disconnected');
});

Getting Started

1. Include the STOMP-WebSocket library in your project:

<script src="https://cdn.jsdelivr.net/npm/@stomp/stompjs@5.0.0/bundles/stomp.umd.min.js"></script>

2. Create a STOMP client and connect to a WebSocket endpoint:

const client = Stomp.client('ws://localhost:15674/ws');

client.connect({}, function(frame) {
    console.log('Connected: ' + frame);
    
    // Subscribe to a topic
    client.subscribe('/topic/messages', function(message) {
        console.log('Received: ' + message.body);
    });
    
    // Send a message
    client.send('/queue/test', {}, 'Hello, World!');
});

3. Remember to handle disconnections and errors:

client.onStompError = function(frame) {
    console.log('Broker reported error: ' + frame.headers['message']);
    console.log('Additional details: ' + frame.body);
};
