The easiest way to set up the development environment is to use the provided setup script:

# Clone the repository
git clone https://github.com/quantsingularity/BlockGuardian.git
cd BlockGuardian

# Run the setup script
./setup_blockguardian_env.sh

# Start the application
./run_blockguardian.sh

1. Backend (backend/):

   • Navigate to the backend directory: cd backend
   • Create a virtual environment: python -m venv venv
   • Activate the virtual environment: source venv/bin/activate (Linux/Mac) or venv\Scripts\activate (Windows)
   • Install dependencies: pip install -r requirements.txt
   • Set up environment variables: cp .env.example .env and edit as needed
   • Run the development server: uvicorn main:app --reload

2. Mobile Frontend (mobile-frontend/):

   • Navigate to the mobile-frontend directory: cd mobile-frontend
   • Install dependencies: npm install or yarn install
   • Start the development server: npm start or yarn start
   • Run on Android or iOS:

     yarn android # or npx react-native run-android
     yarn ios   # or npx react-native run-ios

3. Web Frontend (web-frontend/):

   • Navigate to the web-frontend directory: cd web-frontend
   • Install dependencies: npm install
   • Run in development mode: npm run dev (usually accessible at http://localhost:3000)
   • Build for production: npm run build
   • Start production server: npm run start

A docker-compose.yml file is provided at the root to simplify running the core services (backend, web-frontend). Other services like blockchain nodes or data analysis environments might need separate management or integration into the Docker Compose setup if desired.

# From the project root directory
docker-compose up --build

The repository includes several utility scripts to simplify common tasks:

• setup_blockguardian_env.sh: Sets up the development environment
• run_blockguardian.sh: Starts the application
• lint-all.sh: Runs linting on all code
• validate_code_quality.py: Validates code quality and security

The project maintains comprehensive test coverage across all components to ensure reliability and security.

• Backend API endpoint tests
• Smart contract function tests
• Frontend component tests
• Blockchain connector tests

• End-to-end workflow tests
• Cross-service integration tests
• API contract tests
• Blockchain interaction tests

• Smart contract vulnerability scans
• Penetration testing
• Dependency vulnerability scanning
• Access control testing

To run tests:

# Backend tests
cd backend
pytest

# Smart contract tests
cd blockchain-contracts
npx hardhat test

# Frontend tests
cd web-frontend
npm test

BlockGuardian uses GitHub Actions for continuous integration and deployment:
