*A weather app that uses Angular JS. Angular JS is in LTS and will be ending all support December 31, 2021. *
This app works regardless.
All you need to do is register a free api key at Open Weather Map and then put it in /controllers/get-weather.js in the getWeather controller.
// ...
var location,
apiKey = 'API_KEY',
unitFormat = 'imperial',
day = 'weather';
// ...That's it, nothing special.
