Controller Layer

Task 1: Move the controller to a separate file ( user.controller.js)

    const { UserDAO } = require("./user.dao");

    class UserController
    {        
        const userDAO = new UserDAO();

        async getAllUsers(req, res) {
            const result = await userDAO.findAll();
            res.status(200).json(result);
        
        }
        
        async createUser(req, res) {
            let user = req.body;
            const id = await userDAO.save(user);
            res.status(201).json({ id: id });
        }
    }

    exports.UserController = UserController;

Task 2: Create Separate Router ( router.js)

    const express = require('express');
    const router = express.Router();

    const {UserController} = require("./user.controller");
    const userController = new UserController();

    router.get('/users', userController.getAllUsers);
    router.post('/users', userController.createUser);

    module.exports = router;
