Login and Logout Functionality

We will implement two routes, /login and /logout, which are essential for managing user authentication in a web application:

• User login (/login with the POST method): The /login route is designed to handle user login requests. It allows users to submit their credentials (like username and password) securely. It validates the provided credentials against the stored user data. If the credentials are correct, the user is considered authenticated, and the application can then set up a session or token for the user, allowing them to access protected areas of the application.

• User logout (/logout with the DELETE method): This route manages the termination of a user’s session. When a user accesses this route, the application will invalidate their session or token, effectively logging them out.

Login and logout API implementation

We will create routers for the APIs and implement their handler functions.

Routes

We begin by adding a new route in the routers/router.go file:
