Simple webtask I created to retrieve the current weather from Slack with command: `/wt wttr-in <city-name>`.

wt-wttr-in.js

const got = require('got');

module.exports = (ctx, cb) => {
  var weatherForCity = 'http://api.openweathermap.org/data/2.5/weather?&units=metric&APPID=8b49f82415341963f8768cce938de042&q=' + ctx.body.text;
  got(weatherForCity)
  .then(response => {
    var json = JSON.parse(response.body);
    var weather = json.weather[0].description + ', ' + json.main.temp + ' celcius';
     cb(null, { text: weather});
  })
  .catch(error => {
     cb(null, { text: 'Unable to find the weather for this place: ' + error });
  });
}
