User Login

• URL: /login
• Method: POST

• Request Body: Should include a JSON object with username and password.
• Response: Returns a JWT token if the login is successful.

Protected Route

• URL: /protected

JWT Authentication

The application uses a simple in-memory user database and a secret key for JWT signature. In a real-world scenario, replace the in-memory database with a proper database, and keep the secret key secure.
