Using QPub

Learn how to effectively use QPub in your applications and workflows.

Overview

QPub is a real-time messaging platform that enables instant communication between applications, services, and users through a simple yet powerful publish/subscribe model.

Core Concepts

Channels

Channels are named streams where messages are published and subscribed to. Think of them as topics or rooms where communication happens.

Messages

Messages are the data packets that flow through channels. They can contain any JSON data, text, or binary content.

Publishers and Subscribers

• Publishers: Send messages to channels
• Subscribers: Receive messages from channels

Common Use Cases

Real-time Chat

// Subscribe to chat messages
client.subscribe('chat-room', (message) => {
  displayMessage(message);
});

// Send chat message
client.publish('chat-room', {
  text: 'Hello everyone!',
  author: 'user123'
});

Live Notifications

// Subscribe to user notifications
client.subscribe('user-123-notifications', (notification) => {
  showNotification(notification);
});

Data Streaming

// Stream sensor data
client.subscribe('sensor-data', (data) => {
  updateDashboard(data);
});

Collaborative Features

// Real-time document collaboration
client.subscribe('document-456-changes', (change) => {
  applyDocumentChange(change);
});

Best Practices

1. Use descriptive channel names that clearly indicate their purpose
2. Implement proper error handling for connection issues
3. Consider message size and frequency for optimal performance
4. Use appropriate authentication for sensitive channels
5. Monitor usage to stay within your plan limits
