User Login

  • URL: /login
  • Method: POST
  • Description: Allows users to log in and obtain a JWT token.
  • 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
  • Method: GET
  • Description: A protected route that requires a valid JWT for access.

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.
