Setup and Installation

Prerequisites

• Python 3.9 or higher
• pip package manager

Installation

1. Clone the repository:

   git clone <repository-url>
   cd userauthenticationservice-mt157i
   

2. Create a virtual environment:

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

3. Install dependencies:

   pip install -r requirements.txt
   

4. Set up environment variables (optional):

   export SECRET_KEY="your-secret-key"  # For production, use a secure random key
   export ENVIRONMENT="development"      # Options: development, production
   

Database Setup

The application uses SQLite by default with a database file stored at /app/storage/db/db.sqlite. The directory will be created automatically if it doesn't exist.

To initialize the database with the required tables:

# Initialize Alembic (if you're starting a new project)
alembic init alembic

# Run migrations
alembic upgrade head

Running the Application

Run the development server:

uvicorn main:app --reload

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

Once the application is running, you can access the auto-generated API documentation:

• Swagger UI: http://localhost:8000/docs
