feat intialize router

[martin-markovic]

Description:

Refactor server.js and router.js routing logic. Initialize userFunctions.js and userRoutes.js to handle user routing for modular separation of concerns structure.

router.js

• Imported Router from express.
• Created an instance of Router.
• Imported userRoutes from ../routes/users/userRoutes.js.
• Configured the main router to use userRoutes for handling requests to /api/users.
• Exported the router.

userRoutes.js

• Imported Router from express.
• Created an instance of Router.
• Imported user-related functions: registerUser, getUsers, updateUser, and deleteUser from ../../middleware/users/userFunctions.js.
• Defined the routes:
  • POST /api/users/ to register a new user.
  • GET /api/users/ to get a list of users.
  • PUT /api/users/:id to update an existing user by ID.
  • DELETE /api/users/:id to delete an existing user by ID.
• Exported the user router.

userFunctions.js

• Defined the following middleware functions:
  • registerUser: Handles the registration of a new user.
  • getUsers: Retrieves a list of users.
  • updateUser: Updates a user by their ID.
  • deleteUser: Deletes a user by their ID.
• Each function sends a JSON response with a relevant message.

server.js

• integrate router from ./routes/router.js into server.js.

Summary

These changes modularize the user management functionalities, making the codebase more organized and easier to maintain. The new routes and middleware functions enable essential CRUD operations for user entities through the /api/users endpoint.
