Professional B-esper Frontend Site - Site-wide integration toolkit for full website bot deployment

# B-esper Frontend Site - Complete Architecture Developer Guide

## Overview

The B-esper Frontend Site is the **client-side component** of our enterprise PowerPages architecture. It provides comprehensive bot functionality, debugging tools, and network monitoring through a well-architected system that automatically integrates with PowerPages using URL auto-detection and professional UI rendering.

## Recent Updates

### BSP Logger System

- **Converted from Liquid template to npm site function**: Eliminates Liquid dependencies and provides maintainable JavaScript solution
- **JavaScript-based internationalization**: All translations moved from Liquid variables to JavaScript objects
- **Network tracing capabilities**: Advanced network monitoring interface with XHR/Fetch interception
- **Dual-mode interface**: Toggle between traditional logs and network traces views
- **Skeleton loading system**: Page-specific skeleton loading with centrally styled animations

### Build System Improvements

- **Linting fixes**: Resolved ESLint errors including unused variables and object shorthand requirements
- **API endpoint validation**: Prevents hardcoded endpoints and requires proper environment configuration
- **Enhanced error handling**: Better build validation and environment variable checking

## Architecture Role

This npm package serves as the **JavaScript business logic layer** in our complete architecture:

```
┌─────────────────┐    ┌─────────────────┐    ┌─────────────────┐
│  PowerPages     │    │   NPM Site      │    │ Function App    │
│  (Integration)  │───▶│ (Business Logic)│───▶│ (HTML/CSS)      │
└─────────────────┘    └─────────────────┘    └─────────────────┘
 6-line integration     Auto-detection        Server-side storage
 User data passing      Authentication        Template serving
 Language config        API calls             Style combination
```

**What this package does:**

- ✅ Auto-detects page from PowerPages URL
- ✅ Loads HTML/CSS templates from function app storage
- ✅ Renders professional UI immediately with skeleton loading
- ✅ Handles authentication token acquisition in background
- ✅ Manages all API calls and data loading
- ✅ Provides interactive business logic for all 34 pages

**What this package does NOT do:**

- ❌ Store HTML templates (served by function app)
- ❌ Store CSS styles (served by function app)
- ❌ Handle PowerPages authentication flow (uses existing tokens)
- ❌ Manage Azure infrastructure (handled by APIM + Function App)

## PowerPages Integration (Primary API)

### Automatic URL Detection Integration (RECOMMENDED)

**PowerPages Template Pattern** (copy to all PowerPages):

```html
<div id="besper-site-container"></div>
<script src="https://unpkg.com/besper-frontend-site-{{ settings.enviroment }}-{{ settings.bsp_branch }}@latest/dist/bespersite.js"></script>
<script>
  window.besperAutoPageIntegration({
    user: {% if user %}{ id: "{{ user.id }}", contactid: "{{ user.contactid }}" }{% else %}null{% endif %},
    language: "{{ language.code }}"
  });
</script>
```

**How Auto-Detection Works:**

1. **URL Parsing**: `window.location.pathname` analyzed (e.g., `/manage-workspace`)
2. **Intelligent Mapping**: URL mapped to page ID using smart fallbacks
3. **Environment Detection**: Hostname analyzed for environment (dev/int/prod)
4. **Asset Loading**: HTML/CSS templates loaded from function app storage
5. **Immediate Rendering**: Professional UI shows within ~200ms
6. **Background Processing**: Authentication and data loading happen in parallel

### Manual Override Integration (when needed)

```html
<script>
  window.besperPageIntegration('specific-page-id', {
    user: {% if user %}{ id: "{{ user.id }}", contactid: "{{ user.contactid }}" }{% else %}null{% endif %},
    language: "{{ language.code }}"
  });
</script>
```

## Complete Integration Lifecycle

### Phase 1: PowerPages Call (0-50ms)

```javascript
// PowerPages liquid template calls:
window.besperAutoPageIntegration({
  user: { id: 'user123', contactid: 'contact456' },
  language: 'en',
});
```

### Phase 2: Auto-Detection & Environment Analysis (50-100ms)

```javascript
// npm site analyzes current context:
const pageId = detectPageIdFromUrl(); // '/manage-workspace' → 'manage-workspace'
const environment = detectEnvironmentFromUrl(); // 'dev.powerapps.com' → 'dev'
const branch = 'main'; // default or from settings
```

### Phase 3: Template & Style Loading (100-300ms)

```javascript
// Load HTML/CSS from function app storage via APIM:
const templateLoader = new TemplateLoaderService({ environment, branch });
const { template, styles } = await templateLoader.loadPageAssets(pageId);
// → GET /api/besper-site/template?page_id=manage-workspace
// → GET /api/besper-site/styles?page_id=manage-workspace
```

### Phase 4: Immediate UI Rendering (300-500ms)

```javascript
// Professional UI renders immediately:
const container = document.getElementById('besper-site-container');
container.innerHTML = template; // Professional interface with skeleton loading
templateLoader.applyStyles(styles); // Global + page-specific CSS
```

### Phase 5: Background Authentication (500ms-5s, non-blocking)

```javascript
// Token acquisition happens in background:
const token = await getAuthTokenWithRetry(); // Multiple strategies attempted
// User doesn't wait - UI already rendered and interactive
```

### Phase 6: Data Loading & Business Logic (1-8s)

```javascript
// Page-specific JavaScript loads real data:
const pageClass = await import(`./pages/${pageId}/script.js`);
const page = new pageClass.default({ token, user, language });
await page.loadData(); // Replace skeleton loaders with real content
```

## URL Auto-Detection System

### Intelligent URL Mapping

The npm site uses sophisticated URL analysis to automatically detect the correct page:

```javascript
// URL Detection Strategies (in order of preference):

// 1. EXACT MATCHES (primary mappings)
const exactMappings = {
  '/manage-workspace': 'manage-workspace',
  '/contact-us': 'contact-us',
  '/account-management': 'account-management',
  '/user-management': 'user-management-new',
  '/bot-management': 'bot-management-new',
  '/cost-pool': 'cost-pool-management',
  '/pricing': 'pricing',
  '/home': 'home',
  '/profile': 'profile',
  '/notifications': 'notifications',
  '/support-tickets': 'support-tickets',
  '/help': 'help',
  '/about': 'about-us',
  '/partners': 'partners',
  '/case-studies': 'case-studies',
  '/get-started': 'get-started',
  '/subscription': 'subscription',
  '/my-bots': 'my-bots',
  '/workspace': 'workspace',
  '/workbench': 'workbench',
  '/users': 'users',
  '/invite-user': 'invite-user',
  '/manage-user': 'manage-user',
  '/technical-insights': 'technical-insights',
  '/implementation-guide': 'implementation-guide',
  '/product-purchasing': 'product-purchasing',
  '/upcoming': 'upcoming',
  '/demo': 'demo',
  // ... all 34 pages mapped
};

// 2. PARTIAL MATCHES (intelligent fallbacks)
// '/manage-workspace/details' → 'manage-workspace'
// '/user-management/invite' → 'user-management-new'
// '/bot-management/create' → 'bot-management-new'

// 3. KEYWORD DETECTION (smart fallbacks)
if (pathname.includes('workspace')) return 'manage-workspace';
if (pathname.includes('contact')) return 'contact-us';
if (pathname.includes('user')) return 'user-management-new';
if (pathname.includes('bot')) return 'bot-management-new';
if (pathname.includes('cost')) return 'cost-pool-management';
if (pathname.includes('notification')) return 'notifications';
if (pathname.includes('ticket')) return 'support-tickets';

// 4. DEFAULT FALLBACK
return 'home'; // Ultimate fallback
```

### Environment Auto-Detection

```javascript
// Environment Detection from Hostname:
const hostname = window.location.hostname.toLowerCase();

if (
  hostname.includes('localhost') ||
  hostname.includes('127.0.0.1') ||
  hostname.includes('dev.')
) {
  return 'development';
}
if (hostname.includes('-dev') || hostname.includes('dev-')) {
  return 'dev';
}
if (
  hostname.includes('-int') ||
  hostname.includes('int.') ||
  hostname.includes('staging')
) {
  return 'int';
}
return 'prod'; // Default production environment
```

### Template Loading Service

The `TemplateLoaderService` handles all communication with the function app storage:

```javascript
class TemplateLoaderService {
  constructor({ environment, branch }) {
    this.baseUrl = this.getApiBaseUrl(environment);
    this.branch = branch || 'main';
  }

  async loadPageAssets(pageId) {
    // Parallel loading for optimal performance
    const [templateResponse, stylesResponse] = await Promise.all([
      this.loadTemplate(pageId),
      this.loadStyles(pageId),
    ]);

    return {
      template: templateResponse.content,
      styles: stylesResponse.content, // Already combined: global.css + page.css
    };
  }

  async loadTemplate(pageId) {
    const response = await fetch(
      `${this.baseUrl}/api/besper-site/template?page_id=${pageId}&branch=${this.branch}`
    );
    return await response.json();
  }

  async loadStyles(pageId) {
    const response = await fetch(
      `${this.baseUrl}/api/besper-site/styles?page_id=${pageId}&branch=${this.branch}`
    );
    return await response.json();
  }

  getApiBaseUrl(environment) {
    switch (environment) {
      case 'development':
      case 'dev':
        return 'https://b-esper-apim-dev.azure-api.net';
      case 'int':
        return 'https://b-esper-apim.azure-api.net/int';
      case 'prod':
      default:
        return 'https://b-esper-apim.azure-api.net';
    }
  }
}
```

## Page Architecture (All 34 Pages)

### Page Structure Pattern

Every page follows the same professional architecture pattern:

```
src/pages/{page-id}/
└── script.js          # Business logic, authentication, data management

infra/besper_site_serversite/storage/
├── html/{page-id}/
│   └── template.html   # UI structure with skeleton loading
└── css/{page-id}/
    └── styles.css      # Page-specific styles (global.css always included)
```

### Complete Page Directory Structure

**34 Pages with 1:1 Mapping:**

### Example Page Implementation

**ManageWorkspacePage** - Complete pattern:

```javascript
// src/pages/manage-workspace/script.js
class ManageWorkspacePage {
  constructor(options = {}) {
    this.options = {
      containerId: 'besper-site-container',
      ...options,
    };

    // Template loader handles server-side assets
    this.templateLoader = new window.TemplateLoaderService({
      environment: options.environment,
      branch: options.branch,
    });
  }

  async initialize() {
    try {
      // 1. Load HTML/CSS from function app storage (immediate)
      const { template, styles } =
        await this.templateLoader.loadPageAssets('manage-workspace');

      // 2. Render professional UI immediately
      const container = document.getElementById(this.options.containerId);
      container.innerHTML = template; // Skeleton loading visible to user
      this.templateLoader.applyStyles(styles); // Global + page-specific CSS

      // 3. Setup event listeners for immediate interactivity
      this.setupEventListeners();

      // 4. Load real data in background (token-dependent)
      this.loadWorkspaceData();
    } catch (error) {
      console.error('Failed to initialize Manage Workspace page:', error);
      this.showErrorState();
    }
  }

  setupEventListeners() {
    // Interactive elements work immediately
    const createWorkspaceBtn = document.getElementById('create-workspace-btn');
    if (createWorkspaceBtn) {
      createWorkspaceBtn.addEventListener('click', () =>
        this.createWorkspace()
      );
    }

    // Listen for authentication updates
    window.addEventListener('powerPagesAuthUpdated', event => {
      this.handleAuthenticationUpdate(event.detail);
    });
  }

  async loadWorkspaceData() {
    // This runs in background while user sees professional UI
    // Skeleton loaders get replaced with real data when auth is ready
    const workspaceTable = document.getElementById('workspace-hierarchy-table');

    if (this.options.token) {
      // Token available - load immediately
      const workspaces = await this.fetchWorkspaces();
      this.renderWorkspaces(workspaces, workspaceTable);
    } else {
      // Wait for background authentication
      console.log('[ManageWorkspace] Waiting for authentication token...');
    }
  }

  handleAuthenticationUpdate({ token, userId }) {
    // Authentication completed in background
    this.options.token = token;
    this.options.userId = userId;

    // Now load real data
    this.loadWorkspaceData();
  }

  async fetchWorkspaces() {
    // API calls with authentication token
    const response = await fetch('/api/workspaces', {
      headers: {
        Authorization: `Bearer ${this.options.token}`,
        'Content-Type': 'application/json',
      },
    });
    return await response.json();
  }

  renderWorkspaces(workspaces, container) {
    // Replace skeleton loaders with real workspace data
    container.innerHTML = workspaces
      .map(
        workspace => `
      <div class="workspace-stats-card">
        <h3>${workspace.name}</h3>
        <p>Users: ${workspace.userCount}</p>
        <p>Bots: ${workspace.botCount}</p>
      </div>
    `
      )
      .join('');
  }
}

// Export for global access (required pattern)
window.ManageWorkspacePage = ManageWorkspacePage;
```

## Testing & Validation

### Local Development Testing

**Test URL Auto-Detection:**

```javascript
// Open browser console on any PowerPages site and run:
window.besperAutoPageIntegration({
  user: { id: 'test-user', contactid: 'test-contact' },
  language: 'en',
});

// Should automatically detect page from URL and load appropriate template
```

**Test Manual Page Override:**

```javascript
// Force specific page (useful for testing):
window.besperPageIntegration('manage-workspace', {
  user: { id: 'test-user', contactid: 'test-contact' },
  language: 'en',
});
```

**Test Template Loading Service:**

```javascript
// Test template loading directly:
const loader = new window.TemplateLoaderService({
  environment: 'dev',
  branch: 'main',
});

const assets = await loader.loadPageAssets('manage-workspace');
console.log('Template:', assets.template);
console.log('Styles:', assets.styles);
```

### Function App Endpoint Testing

**Test Template Endpoint:**

```bash
# Test template serving:
curl "https://b-esper-apim-dev.azure-api.net/api/besper-site/template?page_id=manage-workspace"

# Expected response:
{
  "success": true,
  "page_id": "manage-workspace",
  "template": "<div class=\"workspace-container\">...</div>",
  "source": "infra/besper_site_serversite/storage/html/manage-workspace/template.html"
}
```

**Test Styles Endpoint:**

```bash
# Test combined CSS serving:
curl "https://b-esper-apim-dev.azure-api.net/api/besper-site/styles?page_id=manage-workspace"

# Expected response:
{
  "success": true,
  "page_id": "manage-workspace",
  "styles": "/* === GLOBAL STYLES === */\n:root { ... }\n\n/* === PAGE-SPECIFIC STYLES: MANAGE-WORKSPACE === */\n.workspace-hierarchy-table { ... }",
  "sources": ["global.css", "manage-workspace/styles.css"],
  "note": "Combined global + page-specific styles"
}
```

### PowerPages Integration Testing

**Copy Template for Testing:**

```html
<!-- Test template - copy to any PowerPages page -->
<div id="besper-site-container"></div>
<script src="https://unpkg.com/besper-frontend-site-dev-main@latest/dist/bespersite.js"></script>
<script>
  window.besperAutoPageIntegration({
    user: {% if user %}{ id: "{{ user.id }}", contactid: "{{ user.contactid }}" }{% else %}null{% endif %},
    language: "{{ language.code }}"
  });
</script>
```

**Expected Behavior:**

1. **0-200ms**: Container appears, loading starts
2. **200-500ms**: Professional UI renders with skeleton loading
3. **500ms-2s**: Background authentication token acquisition
4. **2-8s**: Real data loads and replaces skeleton loaders
5. **Result**: Fully interactive page with professional interface

## Deployment Architecture

### Function App Deployment

**Static Assets Included** (configured in `.funcignore`):

```
# Function app deployment automatically includes:
infra/besper_site_serversite/storage/
├── css/
│   ├── global.css                    ← Base styles for ALL pages
│   └── [34 page directories]/styles.css
└── html/
    └── [34 page directories]/template.html

# Served via endpoints:
GET /api/besper-site/template?page_id={id}
GET /api/besper-site/styles?page_id={id}
```

**APIM Integration** (automatic routing):

```
PowerPages → APIM → Function App → Local Storage
           ↓
      /api/besper-site/template → decorated_function_logic/get_page_template.py
      /api/besper-site/styles  → decorated_function_logic/get_page_styles.py
```

### NPM Package Deployment

**Build & Publish Process:**

```bash
# Build for specific environment and branch:
cd infra/npm_site
npm run build:dev     # Development build
npm run build:int     # Integration build

```

### Network Trace Features

#### Request Monitoring

- **HTTP Methods**: GET, POST, PUT, DELETE, PATCH tracking
- **Response Analysis**: Status codes, response times, transfer sizes
- **Error Detection**: Failed requests and CORS errors
- **Request Types**: Distinguishes between XHR and Fetch requests

#### Visual Interface

- **Toggle Button**: Switch between logs and network traces views
- **Grid Layout**: DevTools-style request listing
- **Timing Charts**: Visual waterfall representation
- **Status Indicators**: Color-coded status and error highlighting

#### Data Export

- **Copy Functionality**: Export network traces to clipboard
- **CSV Format**: Structured data for analysis tools
- **JSON Export**: Complete request/response data
- **Performance Reports**: Timing analysis summaries

### Internationalization

The logger supports multiple languages with complete UI translations:

```javascript
// English translations
const translations = {
  en: {
    title: 'BSP Logger',
    clear: 'Clear',
    copy: 'Copy All',
    logs: 'Logs',
    networkTraces: 'Network Traces',
    method: 'Method',
    url: 'URL',
    status: 'Status',
    duration: 'Duration',
    size: 'Size',
  },
  de: {
    title: 'BSP Logger',
    clear: 'Löschen',
    copy: 'Alle kopieren',
    logs: 'Protokolle',
    networkTraces: 'Netzwerk-Traces',
    method: 'Methode',
    url: 'URL',
    status: 'Status',
    duration: 'Dauer',
    size: 'Größe',
  },
};
```

### Development Integration

#### Debugging Workflow

1. **Initialize Logger**: Add to your PowerPages template
2. **Monitor Requests**: Use network traces to identify CORS/API issues
3. **Performance Analysis**: Check request timing and bottlenecks
4. **Error Tracking**: Monitor JavaScript errors and stack traces
5. **Export Data**: Copy logs/traces for external analysis

#### CORS Troubleshooting

The logger is particularly useful for debugging CORS issues:

```javascript
// Network trace will show:
// - Preflight requests (OPTIONS)
// - CORS error responses
// - Failed requests with detailed status
// - Response headers analysis
```

### Skeleton Loading System

The logger integrates with the site's skeleton loading system:

#### Layout Management

- **Template Structure**: Skeleton layout defined in page templates
- **CSS Styling**: Centralized skeleton animations in global CSS
- **Smooth Transitions**: Elements transition from skeleton to loaded state
- **Staggered Animation**: 50ms stagger effect for polished experience

#### Implementation

```css
/* Global skeleton styling */
.skeleton-loading {
  background: linear-gradient(90deg, #f0f0f0 25%, #e0e0e0 50%, #f0f0f0 75%);
  background-size: 200% 100%;
  animation: loading 1.5s infinite;
}

@keyframes loading {
  0% {
    background-position: 200% 0;
  }
  100% {
    background-position: -200% 0;
  }
}
```

### Build Requirements

#### Environment Variables

```bash
# Required for npm package build
API_ENDPOINT=https://apimdev0926public.azure-api.net

# Build process
npm run build:env    # Build with API endpoint
npm run validate     # Complete validation (lint + format + test)
npm run test         # Run Jest tests
```

#### Code Quality Standards

- **ESLint**: No unused variables (prefix with `_` for intentionally unused)
- **Prettier**: Consistent code formatting
- **Object Shorthand**: Use ES6 shorthand properties
- **TypeScript**: Type definitions for all APIs

### API Integration

The logger integrates with APIM services for enhanced functionality:

#### APIM Configuration

```javascript
// Automatic endpoint detection
const apiEndpoint =
  process.env.API_ENDPOINT || 'https://apimdev0926public.azure-api.net';

// CORS configuration matches working bot operations
const corsConfig = {
  origin: origin => (string.IsNullOrEmpty(origin) ? '*' : origin),
  credentials: true,
  optionsSuccessStatus: 200,
};
```
