1. Install MongoDB
Download and install MongoDB from the official MongoDB download page.
2. Install MongoDB Compass
Download MongoDB Compass (a GUI for MongoDB) from the MongoDB Compass download page and install it.
Create the Database and Collections
Open MongoDB Compass and connect to your MongoDB server.
Create a new database named restaurant_app_1.
Inside the restaurant_app_1 database, create two collections: users and menu_items.
Format for Collections
1)For 'users' collection there is no need to add any format as in this collection youll see who has logged in
2)For 'menu_items' collection you will have to specify menu items which will be in the format of
{
"name": "Chicken Curry",

}
note: Add this type of 4 to 5 menu items as per your restaurant's menu(basically tis will display menu items which you want to display in your menu)

Application Flow
Home Page: The user is greeted with a home page where they can choose to log in or register.
User Registration: Users can register by providing a username and password. The password is securely hashed before being stored in the database.
User Login: Users can log in with their registered credentials. If successful, they are redirected to the menu page.
Menu Page: The menu page displays all the available dishes fetched from the menu_items collection in MongoDB.
Order Placement: Users can select menu items and place an order.
Order Summary: After placing the order, users are shown a summary of their order along with the total price. They have the option to download this summary as a PDF.
PDF Generation: When the user opts to download the order summary, wkhtmltopdf is used to convert the summary into a PDF document, which is then available for download.
Logout: Users can log out, which clears their session.
