This project is an authentication server built with JavaScript. It authenticates users by checking credentials against a SQLite database and issues JWT tokens to maintain user sessions. New users can also register through the server.

• User registration and authentication
• JWT-based session management
• SQLite database integration

1. Install dependencies:

   npm install

2. Configure environment:
   Create a .env file with your JWT secret and database path.

3. Run the server:

   node app.js

• Passwords are securely hashed in the database.
• JWT tokens should be kept safe on the client side.
