Events - Sleek

Overview

The AI Chat Extension SDK provides a comprehensive event system that notifies your extension about user interactions, query classifications, and UI state changes. Events enable you to track user behavior, trigger analytics, and respond to chat interactions.

Registering event listeners

Use the registerEventListener method to subscribe to SDK events:

import {
  getAiChatExtensionSdk,
  AiChatExtensionSdkEventType,
} from '@sleek/ai-chat-extension-sdk';

getAiChatExtensionSdk().registerEventListener((event, tabDetails) => {
  console.log('Event type:', event.type);
  console.log('Event data:', event.data);
  console.log('Tab details:', tabDetails);

  switch (event.type) {
    case AiChatExtensionSdkEventType.QUERY_CLASSIFIED:
      // Handle query classification
      break;
    case AiChatExtensionSdkEventType.CHAT_PANEL_OPENED:
      // Handle panel opened
      break;
    // ... handle other events
  }
});

You can register multiple listeners, and all will be called when an event occurs.

Event structure

All events follow this structure:

interface AiChatExtensionSdkEvent {
  type: AiChatExtensionSdkEventType;
  data: EventData;  // Type varies by event
}

interface TabDetails {
  tabId: number;
  tabUrl: string;
}

type: The event type (see available events below)
data: Event-specific payload
tabDetails: Information about the tab where the event occurred

Chat panel events base payload

All chat panel events include a chatSessionId in their data payload:

type ChatPanelEventBasePayload = {
  chatSessionId: string;
};

This allows you to correlate events within the same chat session.

Available events

QUERY_CLASSIFIED

Emitted when a user’s query has been analyzed and classified. Event type: AiChatExtensionSdkEventType.QUERY_CLASSIFIED Data payload:

{
  origin: string;                   // Where the query was detected (e.g., 'google', 'chatgpt')

Analytics integration example

Here’s a complete example of integrating SDK events with an analytics service:

import {
  getAiChatExtensionSdk,
  AiChatExtensionSdkEventType,
  type AiChatExtensionSdkEvent,
} from '@sleek/ai-chat-extension-sdk';

// Track session durations
const sessionTimers = new Map<string, number>();

// Register event listener
getAiChatExtensionSdk().registerEventListener((event, tabDetails) => {
  const baseProperties = {
    tabId: tabDetails.tabId,
    tabUrl: tabDetails.tabUrl,
    timestamp: Date.now(),
  };

  switch (event.type) {
    case AiChatExtensionSdkEventType.QUERY_CLASSIFIED:
      analytics.track('ai_chat_query_classified', {
        ...baseProperties,
        origin: event.data.origin,
        classification: event.data.classification,
        query: event.data.query,
        isShoppingQuery: event.data.classification === 'shopping',
      });
      break;

    case AiChatExtensionSdkEventType.CHAT_BADGE_SHOWN:
      analytics.track('ai_chat_badge_shown', {
        ...baseProperties,
        query: event.data.query,
        promptCount: event.data.suggestedPrompts?.length ?? 0,
      });
      break;

    case AiChatExtensionSdkEventType.CHAT_BADGE_CLICKED:
      analytics.track('ai_chat_badge_clicked', {
        ...baseProperties,
        clickedPrompt: event.data.prompt,
        clickedSuggestedPrompt: !!event.data.prompt,
      });
      break;

    case AiChatExtensionSdkEventType.CHAT_BADGE_CLOSED:
      analytics.track('ai_chat_badge_dismissed', {
        ...baseProperties,
        promptCount: event.data.suggestedPrompts?.length ?? 0,
      });
      break;

    case AiChatExtensionSdkEventType.CHAT_PANEL_OPENED:
      sessionTimers.set(event.data.chatSessionId, Date.now());

      analytics.track('ai_chat_panel_opened', {
        ...baseProperties,
        chatSessionId: event.data.chatSessionId,
        hasInitialMessage: !!event.data.initialMessage,
        initialMessage: event.data.initialMessage,
      });
      break;

    case AiChatExtensionSdkEventType.CHAT_PANEL_MESSAGE_SENT:
      analytics.track('ai_chat_message_sent', {
        ...baseProperties,
        chatSessionId: event.data.chatSessionId,
      });
      break;

    case AiChatExtensionSdkEventType.CHAT_PANEL_LINK_CLICKED:
      analytics.track('ai_chat_link_clicked', {
        ...baseProperties,
        chatSessionId: event.data.chatSessionId,
        url: event.data.url,
        merchantName: event.data.merchantName,
        merchantUrl: event.data.merchantUrl,
      });
      break;

    case AiChatExtensionSdkEventType.CHAT_PANEL_PRODUCTS_CLICKED:
      analytics.track('ai_chat_product_clicked', {
        ...baseProperties,
        chatSessionId: event.data.chatSessionId,
        url: event.data.url,
        merchantName: event.data.merchantName,
        merchantUrl: event.data.merchantUrl,
      });
      break;

    case AiChatExtensionSdkEventType.CHAT_PANEL_TOP_MERCHANTS_CLICKED:
      analytics.track('ai_chat_merchant_clicked', {
        ...baseProperties,
        chatSessionId: event.data.chatSessionId,
        url: event.data.url,
        merchantName: event.data.merchantName,
        merchantUrl: event.data.merchantUrl,
      });
      break;

    case AiChatExtensionSdkEventType.CHAT_PANEL_CLOSED:
      const startTime = sessionTimers.get(event.data.chatSessionId);
      const duration = startTime ? Date.now() - startTime : 0;

      analytics.track('ai_chat_panel_closed', {
        ...baseProperties,
        chatSessionId: event.data.chatSessionId,
        sessionDurationMs: duration,
        sessionDurationSeconds: Math.floor(duration / 1000),
      });

      sessionTimers.delete(event.data.chatSessionId);
      break;
  }
});

Debugging events

Enable debug mode to see all events logged to the console:

await initializeAiChatExtensionSdk('your-api-key', {
  enableDebug: true,  // Enable debug logging
  // ... other options
});

You can also add a simple debug listener:

getAiChatExtensionSdk().registerEventListener((event, tabDetails) => {
  console.group(`🎯 SDK Event: ${event.type}`);
  console.log('Data:', event.data);
  console.log('Tab:', tabDetails.tabId, tabDetails.tabUrl);
  console.groupEnd();
});

Best practices

1. Track meaningful metrics

Focus on events that provide business value:

Conversion funnel: QUERY_CLASSIFIED → CHAT_BADGE_SHOWN → CHAT_BADGE_CLICKED → CHAT_PANEL_OPENED
Engagement: Session durations, messages sent, products/merchants clicked
Monetization: Track CHAT_PANEL_LINK_CLICKED, CHAT_PANEL_PRODUCTS_CLICKED, and CHAT_PANEL_TOP_MERCHANTS_CLICKED
Friction points: CHAT_BADGE_CLOSED (dismissals)

2. Handle errors gracefully

Wrap event handlers in try-catch to prevent one handler from breaking others:

getAiChatExtensionSdk().registerEventListener((event, tabDetails) => {
  try {
    // Your event handling logic
    handleEvent(event, tabDetails);
  } catch (error) {
    console.error('Error handling SDK event:', error);
  }
});

3. Avoid blocking operations

Event handlers should be fast and non-blocking. Use async operations carefully:

getAiChatExtensionSdk().registerEventListener((event, tabDetails) => {
  // Good: Fire and forget
  analytics.track(event.type, event.data);

  // Avoid: Blocking async operation
  // await someSlowOperation();
});

4. Use chatSessionId for correlation

Use the chatSessionId field to correlate events within the same chat session:

const sessionMetrics = new Map<string, {
  opened: number;
  messageCount: number;
  linksClicked: number;
}>();

getAiChatExtensionSdk().registerEventListener((event, tabDetails) => {
  if ('chatSessionId' in event.data) {
    const sessionId = event.data.chatSessionId;

    switch (event.type) {
      case AiChatExtensionSdkEventType.CHAT_PANEL_OPENED:
        sessionMetrics.set(sessionId, {
          opened: Date.now(),
          messageCount: 0,
          linksClicked: 0,
        });
        break;

      case AiChatExtensionSdkEventType.CHAT_PANEL_MESSAGE_SENT:
        const metrics = sessionMetrics.get(sessionId);
        if (metrics) metrics.messageCount++;
        break;

      case AiChatExtensionSdkEventType.CHAT_PANEL_LINK_CLICKED:
      case AiChatExtensionSdkEventType.CHAT_PANEL_PRODUCTS_CLICKED:
        const m = sessionMetrics.get(sessionId);
        if (m) m.linksClicked++;
        break;
    }
  }
});
