Node.js API Server for Product Management

Project Description

This project is a simple and basic CRUD (Create, Read, Update, Delete) API server built using Node.js and Express.js, with MongoDB as the database. The API server allows users to manage a collection of products, including creating new products, retrieving product information, updating existing products, and deleting products.

Technologies Used

1. Node.js: A JavaScript runtime environment that allows developers to run JavaScript on the server-side.
2. Express.js: A popular web application framework for Node.js, which provides a robust set of features for web and mobile applications.
3. MongoDB: A NoSQL database used to store and manage the product data.
4. Mongoose: An Object Data Modeling (ODM) library for MongoDB and Node.js, which provides a straightforward, schema-based solution to model your application data.

1. index.js: The main entry point of the app that sets up the Express server, connects to the MongoDB database, and starts the server.

2. product.model.js: Defines the schema for the Product model using Mongoose, including the structure of the product data and the necessary validation rules.

3. product.route.js: Defines the routes for the product API endpoints, linking each route to the corresponding controller function.

4. product.controller.js: Contains the controller functions that handle the CRUD operations for the product collection.

API Endpoints

1. GET /api/products: Retrieves all products.
2. GET /api/products/:id: Retrieves a single product by its ID.
3. POST /api/products: Creates a new product.
4. PUT /api/products/:id: Updates an existing product by its ID.
5. DELETE /api/products/:id: Deletes a product by its ID.

Conclusion

This Node.js API project provides a basic foundation for managing product data using a RESTful API and a MongoDB database. It demonstrates the use of Express.js, Mongoose, and asynchronous programming techniques to build a simple yet functional backend application.
