I'll create a backend implementation for the game management system based on your requirements. I'll use Node.js with Express for the server, MongoDB for the database, and Mongoose for object modeling. I'll create the schema, implement CRUD operations, and set up the necessary routes.

Let's start by setting up the project structure and implementing the required functionality.

Let's begin by creating the necessary files and implementing the functionality:

Now, let me explain the implementation and how it meets your requirements:

1. Schema Model: The game.js file in the models folder defines the schema for the Game model, including all the required fields (gameName, gameType, gameDescription, gamePrice, gameImage, and gameRating).

2. CRUD Functionality: The games.js file in the routes folder implements all the required CRUD operations:

   • CREATE: POST /games
   • READ (all): GET /games
   • READ (one): GET /games/:id
   • UPDATE: PUT /games/:id
   • DELETE: DELETE /games/:id
3. Form Inputs: The schema includes all the necessary fields as per your requirements. The API endpoints expect these fields in the request body.
4. gameName Immutability: In the UPDATE route, there's a check to prevent changing the gameName. If a request tries to update the gameName, it will return a 400 Bad Request error.
5. Folder Structure: The project follows a proper folder structure with separate files for models and routes.
6. RESTful API: The implementation follows RESTful conventions for the API endpoints.

To use this backend:

1. Make sure you have Node.js and MongoDB installed on your system.
2. Create a new directory for your project and copy these files into it.
3. Run npm install to install the dependencies.
4. Start the server with npm start or npm run dev for development with auto-restart.

The server will start on port 3000 (or the port specified in the PORT environment variable).

You can now use these API endpoints to perform CRUD operations on the games. You'll need to implement the frontend separately to interact with these APIs.

Please make sure to add the following environment variable to your project:
