OpenResume API Wrapper

A FastAPI-based backend service that wraps the actual OpenResume codebase to generate professional PDF resumes from JSON data through a REST API.

Attribution

This project is built on top of the excellent OpenResume open-source project by Xitang Zhao. OpenResume is a powerful, open-source resume builder and parser built with Next.js and React. We've created this API wrapper to provide backend access to OpenResume's professional PDF generation capabilities.

All PDF generation, resume templates, and core functionality are powered by the original OpenResume codebase. This wrapper provides a REST API interface to make OpenResume's capabilities accessible as a backend service.

Features

✅ Authentic OpenResume Integration: Uses actual OpenResume React PDF generation logic
✅ REST API Wrapper: Convert OpenResume's frontend into a backend API service
✅ Dual Generation Mode: Primary OpenResume engine + ReportLab fallback
✅ Data Transformation: Seamless conversion from API format to OpenResume format
✅ ATS-Friendly Output: Professional layouts optimized for Applicant Tracking Systems
✅ Comprehensive Validation: Field validation and business logic checks
✅ Health Monitoring: Status endpoints for monitoring OpenResume integration

}

Configuration

The application uses config.json for settings:

• PDF Settings: Font preferences, document size, output directories
• API Settings: Rate limiting, CORS, request size limits
• Validation Rules: Field requirements, content limits
• Logging: Log levels and output format

Testing

Run the test suite from the tests directory:

python tests/perfect_match_tester.py

This verifies:

• API health and responsiveness
• PDF generation functionality
• Template endpoint availability
• Generated file integrity

Test data and sample resumes are available in the tests/ folder.

Architecture

• FastAPI: High-performance web framework with automatic API docs
• OpenResume Integration: Actual OpenResume codebase via Node.js bridge
• ReportLab: Fallback PDF generation when OpenResume unavailable
• Pydantic: Data validation and serialization
• Dual Architecture: Python backend + Node.js OpenResume integration

• Includes comprehensive error handling and logging
• Supports configurable rate limiting and CORS

Docker Troubleshooting

Common Issues

# Port already in use
docker-compose down
sudo lsof -i :5000
kill -9 <PID>

# Permission issues with volumes
sudo chown -R $USER:$USER ./output
chmod 755 ./output

# View container logs
docker logs openresume-api-wrapper
docker-compose logs -f

# Rebuild without cache
docker-compose build --no-cache
docker-compose up --force-recreate
