A robust authentication API built with FastAPI, featuring user registration, login, logout, and token refresh functionality.

• Registration with username, email, and password
• Secure login with JWT authentication
• Logout with token blacklisting
• Token refresh for extended sessions

• Password hashing
• JWT token-based authentication
• Token blacklisting for security
• Rate limiting to prevent abuse

• Prisma ORM integration
• SQLite database (easily configurable to other databases)
• User and BlacklistedToken models

• Backend: FastAPI
• Database: SQLite (via Prisma ORM)
• Authentication: JWT (JSON Web Tokens)
• ORM: Prisma Client Python

1. Clone the repository

git clone https://github.com/yourusername/fastapi-auth-system.git
cd fastapi-auth-system

2. Set up a virtual environment

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

3. Install dependencies

pip install fastapi uvicorn prisma pydantic python-jose passlib bcrypt python-multipart

4. Configure the database

   • Create a .env file with your database URL:

   DATABASE_URL="file:./BOT.sqlite"
   

   • Or update the schema.prisma file directly with your database path

5. Generate Prisma client

prisma generate

6. Run database migrations

prisma migrate dev --name init

7. Start the server

uvicorn main:app --reload

• POST /register - Register a new user
• POST /login - Authenticate and receive tokens
• POST /logout - Blacklist the current token
• POST /refresh - Get a new access token using refresh token
• GET /me - Get current user information (protected)

The application uses two main models:

• id: Unique identifier (auto-incremented)
• username: Unique username
• email: Unique email address
• password: Hashed password

• id: Unique identifier (auto-incremented)
• token: Blacklisted JWT token
• expiresAt: Token expiration timestamp

• Passwords are hashed before storage
• JWT tokens have configurable expiration
• Refresh tokens provide extended sessions
• Token blacklisting prevents token reuse after logout
