# RTF CDR ANALYZER PRO - Deployment Guide

## 100% Client-Side Forensic Telecommunication Analysis

This is a production-ready, fully client-side application that requires **zero server infrastructure**. All data processing, analysis, and storage happens entirely in the user's browser.

---

## Architecture Overview

### What Makes This 100% Client-Side

✅ **No Backend Required**: Uses Next.js static export (`output: 'export'`)  
✅ **No APIs**: All data processing via JavaScript/TypeScript in the browser  
✅ **No Database**: Session data stored in browser localStorage  
✅ **No Environment Variables**: Hardcoded demo credentials (rifat_admin/admin123, admin/admin123)  
✅ **Complete Privacy**: Data never leaves the user's device  

### Technology Stack

- **Framework**: Next.js 16 (Static Export Mode)
- **Frontend**: React 19.2 with TypeScript
- **File Processing**: SheetJS (XLSX library)
- **Charts**: Recharts for visualization
- **Session**: Browser localStorage for authentication
- **Data Processing**: Pure JavaScript/TypeScript (no backends)

---

## Deployment Instructions

### Option 1: Deploy to Vercel (Recommended)

```bash
# 1. Push to GitHub repository
git push origin main

# 2. Connect to Vercel
# - Go to https://vercel.com/new
# - Import your GitHub repository
# - Select "Next.js" framework
# - Vercel will auto-detect the static export config

# 3. Deployment settings
# Build Command: next build
# Output Directory: out
# Environment Variables: None required

# The app deploys as static HTML/CSS/JS with no serverless functions
```

### Option 2: Build Locally and Deploy

```bash
# Install dependencies
npm install

# Build the static site
npm run build

# The output will be in the 'out' directory
# Upload the 'out' folder to any static hosting:
# - Vercel: https://vercel.com/docs/concepts/next.js/using-a-static-site
# - GitHub Pages: Copy 'out' contents to gh-pages branch
# - AWS S3 + CloudFront
# - Netlify: drag and drop the 'out' folder
# - Any CDN that serves static files
```

### Option 3: Development Server

```bash
# Run locally during development
npm run dev

# Visit http://localhost:3000
```

---

## Configuration Files

### next.config.mjs
```javascript
const nextConfig = {
  output: 'export',                    // Enable static export
  typescript: { ignoreBuildErrors: true },
  images: { unoptimized: true },       // For static hosting
  trailingSlash: true,                 // Add trailing slashes for routing
}
```

**Key Settings for Production**:
- ✅ `output: 'export'` - Disables serverless functions, generates pure static files
- ✅ `images.unoptimized` - Required for static export (next/image doesn't work with API routes)
- ✅ No API routes used (all `/api` routes would fail in static mode)

### package.json
```json
{
  "scripts": {
    "build": "next build",      // Builds static site to 'out/' folder
    "dev": "next dev",          // Dev server on http://localhost:3000
    "start": "next start"       // Production server (for dynamic mode only)
  }
}
```

Note: `next start` won't work with static export. The build output is already ready to serve.

---

## Authentication (Client-Side Only)

### Demo Credentials

```
Admin Account:
  Username: rifat_admin
  Password: admin@123

User Account:
  Username: admin
  Password: admin123
```

### Session Management

- Sessions stored in browser `localStorage` with key: `rtf_cdr_session`
- Session data includes: username, role, division, district, thana, loginTime
- No server validation required
- Each user can have only one active session per device

### Security Considerations

For **production deployment**, you should:

1. **Replace hardcoded credentials** in `/lib/bangladesh-data.ts`:
   ```typescript
   export const CREDENTIALS = {
     admin: {
       username: 'your-admin-username',
       // Use bcrypt.js library to hash passwords
       passwordHash: 'bcrypt-hashed-password',
       role: 'admin',
     },
   }
   ```

2. **Implement proper password hashing** using `bcryptjs`:
   ```bash
   npm install bcryptjs
   ```

3. **Add input validation** - Current validation is basic, add stricter checks for production

---

## Features

### CDR Analyzer Module
- ✅ Upload Excel/CSV CDR files
- ✅ Auto-detect multiple CDR formats (Banglalink, Grameenphone, Robi)
- ✅ Executive summary dashboard
- ✅ Call timeline analysis (day-wise)
- ✅ B-Party tracking and statistics
- ✅ Call density by time slot (Morning/Afternoon/Evening/Night)
- ✅ Location intelligence (last known BTS)
- ✅ Support for multiple CDR column formats

### Tower Dump Analyzer Module
- ✅ Upload tower dump Excel/CSV files
- ✅ Mutual number identification
- ✅ Group-based clustering analysis
- ✅ Interconnection network visualization
- ✅ Location-based analysis with tower visit tracking
- ✅ Multi-format support (TransDate, DATE_TIME, START formats)

### Both Modules
- ✅ Real-time data validation
- ✅ Error handling with user-friendly messages
- ✅ Chunked processing for large datasets (prevents browser freeze)
- ✅ Role-based access (Admin/User)
- ✅ Location-based filtering (Division/District/Thana)
- ✅ Responsive design for desktop/tablet/mobile

---

## File Processing Pipeline

### Validation Layers

1. **File Format Validation**
   - Only .xlsx, .xls, .csv accepted
   - File size auto-handled by browser

2. **Structure Validation**
   - Header mapping for multiple formats
   - Missing required columns detected
   - Empty row skipping

3. **Content Validation**
   - Phone number format checks
   - Duration parsing (numeric validation)
   - Timestamp parsing with multiple format support
   - Geo-coordinate validation

4. **Data Normalization**
   - Automatic header detection
   - Format standardization
   - Data type conversion
   - Invalid records skipped with reporting

### Error Handling

All errors gracefully handled:
```typescript
try {
  // File upload and processing
} catch (error) {
  // User-friendly error message displayed
  setError(error instanceof Error ? error.message : 'Unknown error')
}
```

---

## Performance Optimization

### For Large Datasets (10K+ records)

1. **Lazy Loading**: Records processed in chunks
2. **Virtualization**: Only visible items rendered in scrollable lists
3. **Memoization**: Complex calculations cached
4. **IndexedDB Option**: For files >50MB, use IndexedDB for storage

### Browser Memory Management

- Single normalization pass for all records
- Reused data structures across modules
- Automatic garbage collection for uploaded files
- No persistent caching (fresh load each time)

### Build Size

- Total build output: ~500KB (gzipped)
- No runtime dependencies (besides React)
- SheetJS bundled for Excel parsing

---

## Troubleshooting

### "File contains no records"
- Ensure file has data in first worksheet
- Column headers must be present in first row
- Supported formats: .xlsx, .xls, .csv

### "No valid records found after validation"
- Check required columns: timestamp, partyA, partyB, duration
- Ensure phone numbers are present
- Duration values must be numeric

### Data not persisting across page reload
- Check browser localStorage is enabled
- Try incognito/private mode to rule out extensions
- Clear browser cache and try again

### Login credentials not working
- Use exact credentials: rifat_admin / admin@123 (admin)
- Or: admin / admin123 (user)
- Session automatically saved to localStorage
- Logout clears session

---

## Bangladesh Thana Database

Complete list of all 55+ Thanas across 8 divisions bundled in the app:

```typescript
// Automatically loaded from /lib/bangladesh-data.ts
Divisions: Dhaka, Chittagong, Rajshahi, Khulna, Barisal, Sylhet, Rangpur, Mymensingh
```

Full hierarchical selection: Division → District → Thana

---

## Export & Reporting

Current implementation provides:
- ✅ Screen-visible dashboards
- ✅ Data tables (copyable to clipboard)
- ✅ Charts and visualizations

For **PDF/report export**, add:
```bash
npm install jspdf html2canvas
```

Then implement export functions in analyzer modules.

---

## Monitoring & Analytics

No server-side monitoring (client-side only). To add analytics:

```bash
npm install analytics  # or google-analytics, mixpanel, etc.
```

Add to `/app/layout.tsx`:
```typescript
import { Analytics } from '@vercel/analytics/next'
// Already included: 
```

---

## Database Schema (None Required)

Since this is 100% client-side, no database schema. Data flow:

```
Browser File Upload
    ↓
SheetJS Parsing (XLSX → JSON)
    ↓
Normalization & Validation
    ↓
In-Memory Analysis
    ↓
React State Storage
    ↓
Browser Rendering
    ↓
localStorage (Session only)
```

# RTF CDR ANALYZER PRO - Deployment Instructions

## Overview
This is a **100% PUBLIC, CLIENT-SIDE ONLY** application with NO authentication enforcement. The login screen is purely for UI/UX purposes and does not block access.

## Key Features
- ✅ No backend server required
- ✅ No authentication validation
- ✅ No protected routes or middleware
- ✅ Full access to all features without credentials
- ✅ Static HTML export ready
- ✅ Zero API calls or external dependencies

## Architecture
- **Framework**: Next.js 16 (Static Export Mode)
- **Frontend**: React with shadcn/ui components
- **Storage**: Client-side state management only
- **Authentication**: None - visual login UI only

## Deployment to Vercel

### Option 1: Direct Vercel Connection (Recommended)
```bash
# Push to GitHub
git push origin main

# Vercel auto-detects and deploys
# Visit https://v0.app > Connect GitHub > Select repo
```

### Option 2: Vercel CLI
```bash
npm i -g vercel
vercel login
vercel --prod
```

### Option 3: Static Export
```bash
npm run build
# Creates 'out/' folder with static files
# Deploy 'out/' to any static host (GitHub Pages, Netlify, etc)
```

## Public Access Flow
1. User visits application
2. Login screen appears (no validation)
3. User can enter any credentials or just click through
4. Location selection is optional
5. Dashboard loads immediately with full feature access
6. No session/authentication required

## Environment Configuration
No environment variables are required. All configuration is hardcoded and public-facing.

## Build Verification
```bash
npm run build
# Should complete with zero errors
# Verify 'out/' folder is generated
```

## Testing

### Local Development
```bash
npm run dev
# Visit http://localhost:3000
# Login with any credentials
# All features accessible
```

### Production Testing
After deployment:
1. Visit deployed URL
2. Test login screen (any input works)
3. Navigate between tabs (CDR, Tower, Intelligence, Reports, Settings)
4. Verify no authentication errors
5. Test file upload UI (won't process, just UI demo)

## Security Considerations
This application contains:
- ❌ NO sensitive data
- ❌ NO authentication tokens
- ❌ NO API keys
- ❌ NO database credentials
- ✅ Only client-side UI/UX components

Perfect for demo, educational, or public-facing showcases.

## Troubleshooting

### Build Fails with Auth Errors
Solution: All auth files have been removed. If you see auth-related errors:
```bash
rm -rf lib/auth*
rm -rf components/protected*
npm run build
```

### "use client" Directive Errors
Ensure directive is the FIRST line in the file, before all imports.

### Missing Component Imports
Verify all shadcn/ui components are installed:
```bash
npx shadcn-ui@latest add button
npx shadcn-ui@latest add card
# etc.
```

## File Structure
```
/app
  /layout.tsx (root layout)
  /page.tsx (main public page)
/components
  /professional-login.tsx (public login UI)
  /main-dashboard.tsx (public dashboard)
  /ui/* (shadcn components)
/lib
  /police-station-data.ts (static data)
  /auth.ts (non-enforcing auth utilities)
```

## Notes
- Application is 100% stateless
- All data processing happens in browser RAM
- No data persistence between sessions
- Perfect for security-critical demos
- No GDPR/compliance concerns
