Session Initialization

The RKT Chat Client provides a robust session initialization system that automatically manages chat sessions with background processing, telemetry integration, and error handling.

Overview

Session initialization in RKT Chat Client includes:

Automatic Session ID Generation: Unique session identifiers generated when the page is ready
Background Processing: Non-blocking initialization using browser idle time
Telemetry Integration: Comprehensive device and user preference tracking
Error Handling: Graceful error management with tracking integration
State Management: Real-time session state tracking

Key Features

🚀 Non-blocking Initialization

The session initialization process runs in the background to ensure your application remains responsive:

// Uses requestIdleCallback when available
if (typeof window !== "undefined" && "requestIdleCallback" in window) {
  window.requestIdleCallback(initSession, { timeout: 5000 });
} else {
  // Fallback for older browsers
  setTimeout(initSession, 0);
}

📊 Comprehensive Telemetry

Automatically collects device and user information:

Device Information: User agent, language, platform, screen dimensions
User Preferences: Theme (dark/light), timezone, language settings
Session Context: Chatbot ID, session ID, timestamps

🎯 State Management

Track session initialization progress with real-time state updates:

sessionId: Unique identifier for the chat session
isSessionReady: Boolean indicating full initialization completion
telemetryInitialized: Boolean indicating telemetry setup completion

Basic Usage

Simple Implementation

import { useChat } from "@rkt/rkt-chat-client";

const MyChatComponent = () => {
  const {
    sessionId,
    isSessionReady,
    telemetryInitialized,
    messages,
    sendMessage,
  } = useChat({
    chatbot: {
      id: "your-chatbot-id",
      prompt: "You are a helpful assistant.",
    },
    baseUrl: "https://your-api.com/api/chat",
  });

  if (!isSessionReady) {
    return <div>Initializing session...</div>;
  }

  return (
    <div>
      <div>Session ID: {sessionId}</div>
      <div>Telemetry: {telemetryInitialized ? "✅" : "⏳"}</div>
      {/* Your chat interface */}
    </div>
  );
};

With Telemetry and Error Tracking

import { useChat } from "@rkt/rkt-chat-client";

const AdvancedChatComponent = () => {
  const {
    sessionId,
    isSessionReady,
    telemetryInitialized,
    messages,
    sendMessage,
  } = useChat({
    chatbot: {
      id: "your-chatbot-id",
      prompt: "You are a helpful assistant.",
    },
    baseUrl: "https://your-api.com/api/chat",
    telemetry: {
      initializeSession: (data) => {
        console.log("Session initialized:", data);
        // Send to your analytics service
      },
      trackEvent: (event, properties) => {
        console.log("Event tracked:", event, properties);
        // Track user interactions
      },
      trackError: (error, context) => {
        console.error("Error tracked:", error, context);
        // Send to error tracking service
      },
    },
    errorTracker: {
      captureException: (error, context) => {
        console.error("Exception captured:", error, context);
        // Send to error monitoring service
      },
      captureMessage: (message, level, context) => {
        console.log("Message captured:", message, level, context);
        // Log important messages
      },
    },
    onReady: (sessionId) => {
      console.log(`Session ready: ${sessionId}`);
      // Perform any initialization that depends on the session
    },
  });

  return (
    <div>
      {isSessionReady ? (
        <ChatInterface messages={messages} onSend={sendMessage} />
      ) : (
        <LoadingSpinner />
      )}
    </div>
  );
};

Session Lifecycle

Page Load

Component mounts and useChat hook initializes
Session ID generation begins when window is available

Background Initialization

Session initialization runs in browser idle time
Telemetry data collection begins
Device and user preference information gathered

Session Ready

isSessionReady becomes true
onReady callback triggered (if provided)
Chat functionality becomes fully available

Active Session

User can send messages and interact with chat
All telemetry events are tracked
Error handling is active

Browser Compatibility

Feature	Modern Browsers	Legacy Browsers
Background Processing	`requestIdleCallback`	`setTimeout` fallback
Session Management	Full support	Full support
Telemetry	Full support	Full support
Error Handling	Full support	Full support

Performance Considerations

Idle Time Usage: Initialization only runs during browser idle periods
Minimal State: Session state is optimized for React re-renders
Efficient Data Collection: Telemetry data is batched and lightweight
Error Recovery: Graceful degradation on initialization failures
