Configuration

The app connects to MongoDB from server.js and order.js. Before running the project, make sure the MongoDB connection string is valid for your environment.

The local login credentials are loaded from user.json.

Run the App

Start the server with:

npm start

The app runs on port 3000.

Project Structure

• server.js main Express application and routes
• order.js order-related routes
• user.json local username and password data
• package.json project metadata and scripts

Notes

• The app expects Handlebars views and public assets to be available in the project structure used by the server.
• If MongoDB is unavailable, the gallery and order pages will not function correctly.
