Flask Weather App 🌦️

This is a simple weather application built with Flask. It allows users to fetch and display the current weather for any city using the Weatherstack API. The app also logs weather data into a MySQL database for record-keeping.

Features

• Fetch current weather data using the Weatherstack API.
• Store weather data (city, temperature, and description) in a MySQL database.
• Form-based input for city names.
• Flask testing with pytest and API mocking using pytest-mock.

   source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install Dependencies

   pip install -r requirements.txt

4. Set Up Environment Variables Create a .env file in the root directory and add the following:

API_KEY=your_weatherstack_api_key TEST_USER=username TEST_PASSWORD=password 5. Set Up the Database

Install MySQL and create the required databases:

CREATE DATABASE flask_weather_app;
CREATE DATABASE test_flask_weather_app;

Set up the weather_logs table:

USE flask_weather_app;
CREATE TABLE weather_logs (
    id INT AUTO_INCREMENT PRIMARY KEY,
    city VARCHAR(255),
    temperature VARCHAR(255),
    description VARCHAR(255),
    timestamp TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

6. Run the Application

python app.py 7. Access the App Open your browser and visit: http://localhost:5000

Testing Run Tests

bash Copy Edit pytest test_app.py What’s Tested

Home page loads successfully. Weather API mocking to test POST requests without hitting the actual API.

Make sure the .env file is included in .gitignore to prevent exposing secrets. Future Enhancements Add user authentication to log personalized weather searches. Implement pagination for weather logs. Dockerize the application for easier deployment. Contributing Feel free to fork the repository and submit pull requests. Contributions are welcome!
