Backend Creation for Burger App

Overview The backend for the burger app is built using Node.js and Express. It provides RESTful APIs to manage categories and restaurants, supporting the frontend functionalities. Here, I outline the key components and structure of the backend.

API Endpoints Categories API:

GET: https://burgerapp-backend.onrender.com/categories POST: https://burgerapp-backend.onrender.com/categories Restaurants API:

GET: https://burgerapp-backend.onrender.com/restaurants POST: https://burgerapp-backend.onrender.com/restaurants

Key Components Express Router

The Express router is used to define API endpoints for categories and restaurants. It ensures a modular and organized structure.

Category Management

Category Model The Category model defines the schema for categories in the database.

Category Controller Handles the logic for fetching and creating categories. getCategories: Fetches all categories. createCategory: Creates a new category.

javascript const getCategories = async (req, res) => { try { const categories = await Category.find(); res.status(200).json(categories); } catch (error) { res.status(500).json({ message: 'Error fetching categories', error }); } }

const createCategory = async (req, res) => { try { const category = new Category(req.body); await category.save(); res.status(201).json(category); } catch (error) { res.status(500).json({ message: 'Error creating category', error }); } }

module.exports = { getCategories, createCategory };

Category Routes Defines the routes for category-related API requests.

javascript const express = require('express'); const { getCategories, createCategory } = require('../controllers/categoryControllers'); const router = express.Router();

router.get('/', getCategories); router.post('/', createCategory);

module.exports = router;

Restaurant Management Restaurant Model The Restaurant model defines the schema for restaurants in the database.

Restaurant Controller Handles the logic for fetching and creating restaurants.

getAllRestaurants: Fetches all restaurants. createNewRestaurant: Creates a new restaurant.

javascript const getAllRestaurants = async (req, res) => { try { const restaurants = await Restaurant.find(); res.status(200).json(restaurants); } catch (error) { res.status(500).json({ message: 'Error fetching restaurants', error }); } }

const createNewRestaurant = async (req, res) => { try { const restaurant = new Restaurant(req.body); await restaurant.save(); res.status(201).json(restaurant); } catch (error) { if (error.name === 'ValidationError') { res.status(400).json({ message: 'Validation error', errors: error.errors }); } else { res.status(500).json({ message: 'Error creating restaurant', error }); } } }

module.exports = { getAllRestaurants, createNewRestaurant };

Restaurant Routes Defines the routes for restaurant-related API requests.

javascript const express = require('express'); const { getAllRestaurants, createNewRestaurant } = require('../controllers/restaurantControllers'); const router = express.Router();

router.get('/', getAllRestaurants); router.post('/', createNewRestaurant);

module.exports = router;

Conclusion The backend for the burger app is designed to be modular and scalable, providing a robust foundation for the frontend application. By using Express and a schema-based approach for data handling, we ensure consistent and reliable API responses. The complete backend code can be found on my GitHub repository.
