Prerequisites

Python

Please use Python version 3.9. Download and install Python3.9 from the official website: https://www.python.org/downloads/

Ensure you are able to access python from the command-line, verify by executing:

python3.9 --version

Should return the correct Python version number.

Packages

The following Python packages are used for this project:

Flask==2.0.2
Jinja2==3.0.3
mypy==0.931
mypy-extensions==0.4.3
types-Flask==1.1.6
types-Jinja2==2.11.9
types-Werkzeug==1.0.9
typing_extensions==4.0.1
Werkzeug==2.0.2

They are also found in requirements.txt.

Setup Instructions

1. Create a Python virtual environment

python3.9 -m venv shopify_env_2022

Enter the newly created Python virtual environment folder:

cd shopify_env_2022

2. Setup the project environment

Clone the project repository from GitHub:

git clone https://github.com/sammdu/Shopify-Challenge-2022.git

Enter the project repository folder:

cd Shopify-Challenge-2022

Activate the Python virtual environment in your terminal:

source ../bin/activate

After the previous step, you should see the following prompt prepended to your command prompt: (shopify_env_2022), which should be consistent with the Python virtual environment folder name.

Install required Python packages with pip:

pip install -r requirements.txt

Seeing the project in action!

Within an activated virtual environment in the project repository, simply execute the following command to start a Flask development server:

python3.9 ./main.py

This will start a server at http://127.0.0.1:5000/. Visit this address in your browser to see the project in action!

Testing

1. Type verification with mypy

In the project repository root, where the mypy.ini file is located, simply execute the following command to test for type violations:
