This is a simple Flask API for managing product data. The API allows you to perform basic CRUD (Create, Read, Update, Delete) operations on products.

To use this API, you need to have the following software installed on your system:

• Python 3.10 or later
• Flask
• Flask-RESTful
• Flask-Cors
• Peewee

You can install the required packages by running the following command:

pip install -r requirements.txt

1. Open a terminal and navigate to the directory where db.py is located.
2. Run the script for create/update products.db using the following command:

python db.py

• Use the following arguments to customize the script behavior:

-d, --delete_all_data: Deletes all existing product data.
-a, --add_default_data: Adds default product data to the database.
-p, --print_all_data: Prints all product data to the console.

To run the API, execute the following command:

python app.py --host [HOST] --port [PORT]

Replace [HOST] with the IP address or hostname of the server and [PORT] with the port number you want to run the application on.

By default, the application will run on localhost and port 5000.

The API will then be accessible at http://localhost:5000.
