My solution with OpenWeathermap to get LIVE, CURRENT Weather data. 🌩😎☃❅

// Problem: get the weather data with numbers or city names by typing in the console and print out the results

// Solution: use the OpenWeather API key to get the data and display it

// Function to get the HTTPS module

const https = require('https');

// Function tp print message to the console

function printMessage(city, temp){
  const message = `In ${city} the current temperature is ${temp} Celsius`;
  console.log(message);
}

// Function to convert Farenheit to celsius
// Celsius = Kelvin - 273.15

function getCelsius (kelvin){
  const celsius = kelvin - 273.15;
  return Math.round(celsius);
}

// Connect to the OpenWeather API and get the raw data
// Example of calls: api.openweathermap.org/data/2.5/weather?q=London,uk

function getTemp (city) {
    const request = https.get(`https://api.openweathermap.org/data/2.5/weather?q=${city}&APPID=8af2aa7fa978da0c3dc608a85406875c`, response => {
      let body = '';
      // Read the data
      response.on('data', data => {
        body += data.toString();

      }); //data reads ends
      // Parse it 

      response.on('end', data => {
      const weather = JSON.parse(body);
      printMessage(city, getCelsius(weather.main.temp));

      }); // parse ends

    }); //request ends  


} // getTemp funciton ends

// Print out data to the console

// Make it flexible with ARGV key

const getCityTemp = process.argv.slice(2);
getCityTemp.forEach(getTemp);
