This weather app makes calls to OpenWeatherMap website's API to get current weather and forecasts for the city provided by a user.
If you want to test it, you must create an account on the OpenWeathermap and obtain the personal API key.
And put it right into the API url, instead of ${config.apiKey} https://api.openweathermap.org/data/2.5/${endPoint}?q=${city}&appid=${config.apiKey}&units=metric;
