Flask Weather API

This README provides instructions for setting up and running the Flask API application on macOS using Homebrew and virtual environments.

Prerequisites

• macOS operating system
• Homebrew installed (Installation guide)

Prepare to Run API

1. Download Python with Homebrew

Open Terminal and run the following command to install Python 3 using Homebrew:

brew install python

2. Set up Python Virtual Environment

Navigate to the Flask project base directory in Terminal and create a virtual environment using the following command:

python3 -m venv venv

3. Activate Python Virtual Environment

Activate the virtual environment by running:

``source venv/bin/activate```

4. Install Requirements Recursively

While in the activated virtual environment, install the project dependencies recursively using the following command:

pip install -r requirements.txt

Run the API

1. Activate Python Virtual Environment if not Activated

Activate the virtual environment by running: python3 -m venv venv

2. Set API Key Variable

Set your Personal Weather API Key variable from OpenWeatherMap In your terminal use the command

WEATHER_API_KEY=<actual_api_key>

3. Run the API application

Start the API using python main.py

4. Test Python Main Application in Browser

Open your web browser and navigate to the following URL: http://127.0.0.1:5000/weather?lat=40.468530&long=-111.923490

You will receive a response like:

{
"Conditions": "Few Clouds",
"Temp": "Cold"
}

Unit Tests

To run unit tests, execute the following command in Terminal:

`python test_main.py``

This will run all the unit tests and provide the test results.

Additional Notes

Customize the port number in your main.py file if it's different from the default Flask port (5000).
