Weather App

This Weather App is a command-line application written in Go that allows you to fetch real-time weather data for any location based on a zip code. The app leverages the WeatherAPI.com to retrieve and display detailed weather information, including temperature, humidity, wind speed, and more.

Features

• Real-Time Weather Data: Get up-to-date weather information for any location by entering its zip code.
• Detailed Weather Metrics: Displays temperature, weather condition, humidity, wind speed, cloud cover, visibility, and more.
• User Input: Dynamically input the zip code to retrieve specific weather data for any location.
• Environment Variable for API Key: Store your WeatherAPI.com API key securely in an .env file.

Prerequisites

• Go: You must have Go installed on your system.
• WeatherAPI.com API Key: You need to sign up for a free API key from WeatherAPI.com.

Installation

1. Clone the Repository:

   git clone https://github.com/rlanier-webdev/go-weatherapp.git
   cd weather-app

2. Set Up Your API Key:

   • Create a .env file in the root directory of the project.
   • Add your WeatherAPI.com API key to the .env file:

     APIKEY=your_api_key_here

   • Ensure your .env file is included in your .gitignore to keep it out of version control:

     echo ".env" >> .gitignore

3. Install Go Modules:

   • If you are using Go modules, ensure that your dependencies are up-to-date by running:

     go mod tidy

4. Build the Application:

   go build -o go-weatherapp

5. Run the Application:

   ./go-weatherapp

Usage

1. When you run the application, it will prompt you to enter the zip code of the location for which you want to retrieve weather data:

   Enter the zip code of the location:

2. After entering the zip code, the application will fetch and display the weather information, including:

   • Location name
   • Temperature (in Celsius and Fahrenheit)
   • Weather condition (e.g., sunny, cloudy)
   • Humidity
   • Wind speed
   • Feels-like temperature
   • Visibility
   • UV Index
   • Wind gusts

Example output:

Location: Saint Louis, Missouri, USA
Temperature: 22.8°C (73.0°F)
Condition: Partly cloudy
Humidity: 46%
Cloud Cover: 75%
Feels Like: 24.2°C (75.5°F)
Wind Speed: 10.5 mph (16.9 kph)
Wind Chill: 22.4°C (72.3°F)
Heat Index: 23.9°C (75.0°F)
Dew Point: 7.3°C (45.2°F)
Visibility: 16.0 km (9.0 miles)
UV Index: 6.0
Gust: 15.0 mph (24.1 kph)

Environment Variables

To securely manage your WeatherAPI.com API key:

1. Create a .env File:

   • Place your API key in a .env file at the root of the project:

     APIKEY=your_api_key_here

2. Load the API Key in Your Code:

   • Use a package like godotenv to load the environment variables in your Go application:

     import (
         "os"
         "github.com/joho/godotenv"
     )
     
     func init() {
         err := godotenv.Load()
         if err != nil {
             fmt.Println("Error loading .env file")
         }
     }
     
     func main() {
         apiKey := os.Getenv("APIKEY")
         // Use apiKey for your API requests
     }
