# Integration Complete! 🎉

## What We've Done:

### ✅ 1. Fixed Environment Variables
- Updated `.env` files with correct `APP_NAME=resumeformatter`
- Added Cloudflare R2 credentials to root `.env`
- Fixed frontend `.env` to use `VITE_APP_NAME=resumeformatter`

### ✅ 2. Added Backend Dependencies
Added to `requirements.txt`:
- `boto3==1.34.51` - AWS SDK (works with R2)
- `python-multipart==0.0.9` - For file uploads
- `google-generativeai==0.3.2` - Gemini AI SDK

### ✅ 3. Created R2 Service (`backend/app/services/r2_service.py`)
Functions:
- `list_templates()` - Get all templates from R2
- `get_template_content(name)` - Download template HTML
- `upload_converted_file()` - Upload HTML/PDF to R2
- `list_converted_resumes()` - Get conversion history
- `get_file_url()` - Generate presigned download URLs

### ✅ 4. Created AI Service (`backend/app/services/ai_service.py`)
Functions:
- `extract_text_from_resume()` - Extract text from PDF/DOCX using Gemini Vision
- `generate_html_from_template()` - Merge resume data into template using Gemini

### ✅ 5. Created Resume API Endpoints (`backend/app/api/endpoints/resumes.py`)
Endpoints:
- `GET /api/resumes/templates` - List available templates
- `GET /api/resumes/templates/{name}` - Get template content
- `POST /api/resumes/convert` - Convert resume (accepts file + template name)
- `GET /api/resumes/history` - Get conversion history
- `GET /api/resumes/download/{key}` - Get download URL

### ✅ 6. Updated Configuration
- Added R2 and Gemini settings to `backend/app/core/config.py`
- Updated `docker-compose.yml` to pass environment variables
- Registered resume endpoints in API router

## Next Steps:

### 🎯 Option 1: Test Docker Build (Recommended)
Since you don't have Node.js installed locally, use Docker:

```bash
# Build and run with Docker
docker-compose up --build
```

Then test at: http://localhost:8080/resumeformatter

### 🎯 Option 2: Update Frontend to Use Backend API

The frontend currently has mock R2 functions. We need to:
1. Create API service functions in frontend
2. Replace mock functions with real API calls
3. Remove AI logic from frontend (now handled by backend)

### 🎯 Option 3: Install Node.js for Local Development

If you want to develop locally:
```bash
# Install Node.js (macOS)
brew install node

# Then install frontend dependencies
cd frontend
npm install
```

## API Flow Example:

1. **User uploads resume.pdf + selects "Google" template**
2. **Frontend → POST /api/resumes/convert**
   - Sends file + template_name
3. **Backend extracts text** → Gemini Vision API
4. **Backend fetches template** → R2 Storage
5. **Backend generates HTML** → Gemini Text API
6. **Backend uploads HTML** → R2 Storage
7. **Backend returns** → { html_content, html_url }
8. **Frontend displays preview** and allows download
