Live API Event Map (WebSocket Demo)

This project demonstrates how to connect to the The Dog API / The Cat API WebSocket Realtime Gateway to visualize API events (votes, favourites, uploads) as they happen across the world.

Live links to test

• Map: https://live.thedogapi.com/
• Favourite or Vote Up/Don images to see them live on the above Map: https://thedogapi.com/en/students

📂 Project Structure

• map.html
  A simplified, full-screen map experience. It automatically connects to the WebSocket gateway on load and displays events on a global map.

• index.html
  An interactive version with a settings panel. You can manually configure the WebSocket URL, API Key, and toggle image attachments. It also includes a scrolling event log alongside the map.

• events.html
  A "WebSocket Tester" dashboard focused on logging raw events. Useful for debugging connection issues or inspecting the raw JSON payload of events.

🚀 How to Implement (WebSocket API)

The API provides a real-time stream of user interactions. You can use this to build live dashboards, activity feeds, or analytical tools.

Connection Details

• WebSocket URL: https://api.thedogapi.com (Production)
• Transport: websocket (Mandatory: Long-polling is disabled on serverless infrastructure)
• Auth: Pass your API Key via the x-api-key header (handshake or extraHeaders).

Implementation Example (Socket.IO v4)

<script src="https://cdn.socket.io/4.7.2/socket.io.min.js"></script>
<script>
    const socket = io('https://api.thedogapi.com', {
        transports: ['websocket'], // ⚠️ IMPORTANT: Force websocket transport
        auth: {
            'x-api-key': 'YOUR_API_KEY', // Get one for free at thedogapi.com
            'attach_image': 'true'       // Optional: Ask server to lookup image details
        },
        extraHeaders: {
            // Some clients/proxies require headers here too
            'x-api-key': 'YOUR_API_KEY',
            'attach_image': 'true'
        }
    });

    socket.on('connect', () => {
        console.log('Connected to Realtime Gateway!');
    });

    socket.on('disconnect', () => {
        console.log('Disconnected');
    });

    // Listen for all events
    socket.onAny((eventName, data) => {
        console.log(`Received ${eventName}:`, data);
        
        // Example Data Structure:
        // {
        //   "id": 12345,
        //   "image_id": "b1",
        //   "value": 1,
        //   "_metadata": {
        //     "event_type": "vote",
        //     "country_code": "US"
        //   },
        //   "image": { "url": "..." } // Only if attach_image=true
        // }
    });
</script>

Key Parameters

Header / Auth	Value	Description
x-api-key	string	Required. Your API Key.
attach_image	'true' | 'false'	Optional. If true, the server performs a DB lookup to include image URL/metadata in the event payload. Default is false (faster).
