Angular

Angular 18+ (Standalone Component)

import { Component, OnInit, OnDestroy } from '@angular/core';
import '@glossaai/chat-sdk/styles';

declare global {
  interface Window {
    GlossaChat: any;
    GlossaAngularService: any;
  }
}

@Component({
  selector: 'app-root',
  standalone: true,
  template: '<router-outlet />'  // SDK automatically adds the widget
})
export class AppComponent implements OnInit, OnDestroy {
  ngOnInit() {
    // SDK automatically adds the widget to document.body
    import('@glossaai/chat-sdk').then(() => {
      window.GlossaChat?.initAngular({
        botCode: 'your-bot-code',  // Required: 11-character bot code
        chatServiceUrl: 'https://panel.glossaai.ir'  // Optional: defaults to this
      });
    });
  }

  ngOnDestroy() {
    if (window.GlossaChat?.isOpen) {
      window.GlossaChat.closeChat();
    }
  }
}

Angular (Classic Module-based)

import { Component, OnInit, OnDestroy } from '@angular/core';
import '@glossaai/chat-sdk/styles';

declare global {
  interface Window {
    GlossaChat: any;
    GlossaAngularService: any;
  }
}

@Component({
  selector: 'app-root',
  template: '<router-outlet></router-outlet>'
})

</html>

Configuration

Options

{
  // Required
  botCode: string;              // Your bot code (11 characters, obtained from Glossa panel)
  
  // Optional
  chatServiceUrl?: string;      // Chat service URL (default: 'https://panel.glossaai.ir')
  
  // Note: The following settings are loaded from bot API automatically:
  // - primaryColor: Bot's primary color (from bot settings in panel)
  // - position: Widget position (from bot settings)
  // - welcomeMessage: Welcome message (from bot settings)
  // - showAvatar: Show/hide avatar (from bot settings)
  // - avatarUrl: Bot avatar URL (from bot settings)
  // - name: Bot name (from bot settings)
}

Important: Your botCode must be valid and associated with an active subscription. Invalid or expired bot codes will result in initialization errors.

Methods

// Initialize (use framework-specific method)
await window.GlossaChat.initAngular(config);   // Angular
await window.GlossaChat.initReact(config);      // React
await window.GlossaChat.initVue(config);        // Vue
await window.GlossaChat.init(config);           // Vanilla JS

// Control chat
window.GlossaChat.openChat();
window.GlossaChat.closeChat();
window.GlossaChat.toggleChat();

// Send message
window.GlossaChat.sendMessage('Hello!');

// Get info
const sessionId = window.GlossaChat.getSessionId();
const isInit = window.GlossaChat.isInitialized;
const isOpen = window.GlossaChat.isOpen;

Events

Monitor chat state through properties:

if (window.GlossaChat.isInitialized) {
  console.log('SDK is ready');
}
if (window.GlossaChat.isOpen) {
  console.log('Chat is open');
}

Styling

Importing Styles

The SDK includes all styles and fonts bundled. Simply import the styles:

// ✅ Recommended: Import styles (includes fonts automatically)
import '@glossaai/chat-sdk/styles';

// ✅ Alternative: Import CSS file directly
import '@glossaai/chat-sdk/styles.css';

Important:

• ✅ No manual font setup needed - Vazirmatn fonts are automatically included as base64 inline fonts
• ✅ No need to copy font files - Everything is bundled in the CSS
• ✅ Works with all bundlers - Webpack, Vite, Rollup, etc.

Customizing Styles

You can override default styles:

/* Override default styles */
.glossa-chat-container {
  /* Your custom styles */
}

.glossa-chat-button {
  background-color: your-color !important;
}

.glossa-chat-panel {
  /* Custom chat panel styles */
}

Fonts

The SDK uses Vazirmatn font for Persian/Arabic text support. Fonts are:

• ✅ Automatically bundled as base64 inline fonts
• ✅ No external font files needed
• ✅ No @font-face declarations needed
• ✅ Works offline

API Integration

This SDK works with the Glossa Chat Service and integrates with the full Glossa AI Platform.

Chat Service URL

Set the chatServiceUrl to your chat service endpoint:

{
  chatServiceUrl: 'https://panel.glossaai.ir'  // Production (default)
  // or
  chatServiceUrl: 'http://localhost:3001'      // Development
}

Platform Architecture

The Glossa platform consists of:

1. Customer Panel: Bot management, configuration, and analytics
2. Chat Service: Real-time messaging service (port 3001)
3. Chat SDK: This package for embedding chat widgets
4. RAG API: AI-powered response generation service
5. Multi-Platform Connectors: Telegram, WhatsApp, Bale, Eitaa integrations

Backend Services

• WhatsApp: Direct connection via Baileys (no third-party API required)
• Telegram: Webhook-based integration
• Bale & Eitaa: Native bot API integration
• RAG API: Document-based AI responses with context awareness

CORS Configuration

Critical: You must configure allowed domains in your bot settings:

1. Log in to the Glossa Customer Panel
2. Navigate to your bot settings
3. Add your website domain(s) to the "Allowed Origins" list
   • Example: https://example.com (no trailing slash)
   • You can add up to 2 domains per bot
   • Wildcard (*) is not allowed for security
4. Save your settings

Requests from domains not in your allowed list will be blocked by CORS policy.

TypeScript Support

The SDK includes built-in TypeScript type definitions. No manual type declarations needed!

Automatic Type Support

When you install the SDK, TypeScript automatically recognizes the types:

// ✅ Just import - types are automatically available
import GlossaChatSDK from '@glossaai/chat-sdk';

const sdk = new GlossaChatSDK();
// ✅ Full autocomplete and type checking
await sdk.init({ botCode: 'your-bot-code' });

Type Definitions Included

The SDK provides complete type definitions for:

• SDKConfig: Configuration interface
• BotConfig: Bot settings interface
• InitResult: Initialization result interface
• BotConfigResult: Bot config API response interface
• GlossaChatSDK: Main SDK class with all methods

Example with TypeScript

import GlossaChatSDK, { SDKConfig, InitResult } from '@glossaai/chat-sdk';

const config: SDKConfig = {
  botCode: 'your-bot-code',
  chatServiceUrl: 'https://panel.glossaai.ir'
};

const sdk = new GlossaChatSDK();
const result: InitResult = await sdk.init(config);

if (result.success) {
  console.log('SDK initialized:', result.message);
} else {
  console.error('Initialization failed:', result.error);
}

Global Window Types (Optional)

If you're using the global window.GlossaChat instance, you can optionally extend the Window interface:

declare global {
  interface Window {
    GlossaChat: InstanceType<typeof import('@glossaai/chat-sdk').default>;
    GlossaAngularService?: any;
    GlossaReactHook?: any;
    GlossaVuePlugin?: any;
  }
}

Note: This is optional. The SDK's built-in types work automatically when importing the module.

Troubleshooting

Chat widget not appearing

1. Check console for errors
2. Verify botCode is correct (11 characters)
3. Ensure your bot subscription is active
4. Verify domain is added to allowed origins in bot settings
5. Check if SDK script is loaded: console.log(window.GlossaChat)

Initialization errors

1. Invalid bot code: Verify your bot code in the customer panel
2. Expired subscription: Check if your subscription is still active
3. Bot not found: Ensure bot exists and is not deleted
4. Inactive bot: Make sure bot is enabled in settings
5. Check browser console for detailed error messages

CORS errors (blocked by CORS policy)

Most common issue! If you see:

Access to fetch has been blocked by CORS policy

Solutions:

1. Add your domain to "Allowed Origins" in bot settings (customer panel)
2. Remove trailing slashes from your domain (use https://example.com not https://example.com/)
3. Use exact domain match (protocol + domain, no wildcards)
4. Wait 5 minutes for cache to clear after updating origins
5. Verify you're testing from the same domain you configured

Connection errors

1. Check network connectivity
2. Verify chat service URL is correct (https://panel.glossaai.ir)
3. Check browser DevTools Network tab for failed requests
4. Ensure you're not behind a firewall blocking the API
5. Verify your subscription payment is up to date
6. Check if RAG API is accessible and configured correctly
7. Verify bot is active and enabled in customer panel

Platform-specific issues

WhatsApp Integration:

• Ensure QR code is scanned successfully
• Check session files are not corrupted
• Verify Baileys connection is stable

Telegram/Bale/Eitaa:

• Verify bot token is correct
• Check webhook URL is configured properly
• Ensure bot is active in platform settings

Auto-Configuration (Recommended)

You can configure the SDK without writing any JavaScript code. The SDK will automatically detect and initialize using one of these methods:

Method 1: Data Attributes (Easiest)

<script 
  src="https://unpkg.com/@glossaai/chat-sdk/dist/glossa-chat-sdk.umd.js"
  data-bot-code="your-bot-code"
  data-chat-service-url="https://panel.glossaai.ir">
</script>
<!-- Note: Bot settings (primaryColor, welcomeMessage, etc.) are loaded from API -->

Method 2: Meta Tags

<head>
  <meta name="glossa-bot-code" content="your-bot-code">
  <meta name="glossa-chat-service-url" content="https://panel.glossaai.ir">
  <!-- Note: primaryColor and other bot settings come from API, not from meta tags -->
</head>

Method 3: Global Config

<script>
  window.GLOSSA_CONFIG = {
    botCode: 'your-bot-code',
    chatServiceUrl: 'https://panel.glossaai.ir'
    // Note: primaryColor is loaded from bot API, not from this config
  };
</script>
<script src="...glossa-chat-sdk.umd.js"></script>

Important Notes:

• If botCode is found using any of these methods, the SDK will automatically initialize. You don't need to call init() manually.
• Bot settings like primaryColor, welcomeMessage, position, avatarUrl, etc. are automatically loaded from the bot API based on the botCode. You don't need to configure them manually.
• Only botCode and chatServiceUrl can be configured. All other settings come from your bot configuration in the Glossa panel.
