# WebSocket Events

## Connection

Connect to the WebSocket server:

```javascript
const ws = new WebSocket('ws://localhost:3000/ws/v1');

// Send authentication immediately after connection
ws.send(JSON.stringify({
    type: 'auth',
    public_key: 'your_public_key_hex',
    timestamp: new Date().toISOString(),
    signature: 'ed25519_signature_hex'

}
```

## Best Practices

1. **Connection Management**
   * Implement reconnection logic with exponential backoff
   * Keep track of subscription state
   * Handle connection drops gracefully
2. **Event Processing**
   * Process events in order
   * Maintain local state
   * Handle out-of-order events
3. **Performance**
   * Subscribe only to needed topics
   * Batch event processing when possible
   * Monitor memory usage for stored events

## Example Implementation

```javascript
class ChaosChainClient {
    constructor(url, publicKey, privateKey) {
        this.url = url;
        this.publicKey = publicKey;
        this.privateKey = privateKey;
        this.connect();
    }

    connect() {
        this.ws = new WebSocket(this.url);
        
        this.ws.onopen = () => {
            this.authenticate();
            this.subscribe(['blocks', 'consensus']);
        };

        this.ws.onmessage = (event) => {
            const data = JSON.parse(event.data);
            this.handleEvent(data);
        };

        this.ws.onclose = () => {
            setTimeout(() => this.connect(), 5000);
        };
    }

    authenticate() {
        // Implementation details
    }

    subscribe(topics) {
        // Implementation details
    }

    handleEvent(event) {
        switch(event.type) {
            case 'block_proposal':
                // Handle new block
                break;
            case 'consensus_discussion':
                // Handle discussion
                break;
            // ... handle other events
        }
    }
}
```

## Debugging Tips

1. Use the debug endpoint to monitor WebSocket state:

```http
GET /api/v1/debug/ws/{connection_id}
```

2. Enable verbose logging:

```javascript
ws.onmessage = (event) => {
    console.log('Raw event:', event.data);
    // ... handle event
};
```

3. Monitor connection health:

```javascript
setInterval(() => {
    if (ws.readyState !== WebSocket.OPEN) {
        console.log('Connection lost, reconnecting...');
        connect();
    }
}, 5000);
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://chaoschain.gitbook.io/chaos/agent-development/api-reference/websocket.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
