Installation

Prerequisites

• Python 3.10 or higher
• pip (Python package manager)

Setup

1. Clone the repository:

   git clone https://github.com/yourusername/comprehensiveecommerceplatform.git
   cd comprehensiveecommerceplatform
   

2. Create a virtual environment:

   python -m venv venv
   source venv/bin/activate  # On Windows, use: venv\Scripts\activate
   

3. Install dependencies:

   pip install -r requirements.txt
   

4. Initialize the database:

   python -m app.utils.db_init
   

Running the Application

Start the application with:

uvicorn main:app --reload

The API will be available at http://localhost:8000.

• Interactive API documentation: http://localhost:8000/docs
• Alternative API documentation: http://localhost:8000/redoc
• Health check endpoint: http://localhost:8000/health

API Documentation

The API is fully documented with OpenAPI. You can explore the documentation using the interactive Swagger UI at /docs or ReDoc at /redoc.

Authentication

Most endpoints require authentication using JSON Web Tokens (JWT).

To authenticate:

1. Register a user using the /api/auth/register endpoint
2. Login using the /api/auth/login endpoint
3. Use the returned access token in the Authorization header: Authorization: Bearer {your_access_token}

Default Admin Account

A default admin account is created when you initialize the database:

• Email: admin@example.com
• Password: admin

Database Migrations

The project uses Alembic for database migrations. The initial migration is already set up.

To create a new migration after making changes to the models:

alembic revision --autogenerate -m "Description of changes"

To apply migrations:

alembic upgrade head

Adding New Features

When adding new features:

1. Define models in app/models/
2. Create Pydantic schemas in app/schemas/
3. Implement business logic in app/services/
4. Create API endpoints in app/routers/
5. Register new routers in main.py
6. Generate and apply database migrations

Code Quality

Run linting and formatting with:

./scripts/lint.sh

Deployment

Production Configuration

For production deployment:

1. Set up a proper database (e.g., PostgreSQL) by updating the connection settings in app/core/config.py
2. Configure proper authentication for production in app/core/config.py
3. Update CORS settings in main.py to restrict allowed origins
4. Set up a reverse proxy (e.g., Nginx) in front of the application
5. Configure HTTPS

Docker Deployment

A Dockerfile is included for containerized deployment:

docker build -t ecommerce-api .
docker run -p 8000:8000 ecommerce-api
