A Flask web application with automatic dependency updates using GitHub Dependabot. This project demonstrates how to set up automated dependency management for Python applications.

• Flask Web Application: RESTful API with user management
• Automatic Dependency Updates: Daily dependency scanning and PR creation via Dependabot
• Database Integration: SQLAlchemy with Flask-Migrate for database management
• Testing: Comprehensive test suite with pytest
• Code Quality: Black formatting, flake8 linting, and safety checks

• Python 3.11+
• pip
• Git

1. Clone the repository

   git clone https://github.com/DevSecCube/dependabot-automatic-pr.git
   cd dependabot-automatic-pr

2. Create and activate virtual environment

   python -m venv .venv
   
   # On Windows
   .venv\Scripts\activate
   
   # On macOS/Linux
   source .venv/bin/activate

3. Install dependencies

   pip install -r requirements.txt

4. Install development dependencies

   pip install -r requirements-dev.txt

1. Set environment variables (optional)

   # Default uses SQLite database
   export DATABASE_URL="sqlite:///app.db"

2. Initialize the database

   flask db init
   flask db migrate -m "Initial migration"
   flask db upgrade

3. Run the application

   flask run

The application will be available at http://localhost:5000

• GET /health - Health check endpoint
• GET /users - Retrieve all users
• POST /users - Create a new user (requires email in JSON body)

# Health check
curl http://localhost:5000/health

# Create a user
curl -X POST http://localhost:5000/users \
  -H "Content-Type: application/json" \
  -d '{"email": "user@example.com"}'

# Get all users
curl http://localhost:5000/users

Run the test suite:

# Run all tests
pytest

# Run with coverage
pytest --cov=app

# Run with verbose output
pytest -v

• Black: Code formatting

  black app/ tests/

• Flake8: Linting

  flake8 app/ tests/

• Safety: Security vulnerability scanning

  safety check

# Create a new migration
flask db migrate -m "Description of changes"

# Apply migrations
flask db upgrade

# Rollback migrations
flask db downgrade

This project includes automatic dependency updates via GitHub Dependabot. The configuration (.github/dependabot.yml) is set to:

• Package Ecosystem: pip (Python)
• Schedule: Daily updates
• Scope: Direct and indirect dependencies
• PR Limit: Maximum 10 open pull requests

Dependabot will automatically:

1. Check for outdated dependencies daily
2. Create pull requests with updates
3. Include changelog information
4. Run tests to ensure compatibility
