martinsahlen/yr.no-forecast

Node.js module to get weather forecast data in JSON format from yr.no service.

yr.no-forecast

Wrapper to easily get weather data for a specified location in JSON format. Uses yr.no-interface under the hood. See the API docs at yr.no.

###Usage Use the getWeather(queryStringParams, callback|stream, [VERSION]) function to get a LocationForecast object, where version represents the version of the "locationforecast" service to use. This object has functions that take a callback as parameter and are detailed in the example below.

var yrno = require('yr.no-forecast');
yrno.getWeather({
  lat: 53.3478,
  lon: 6.2597
}, function(err, location) {
  // Weather for next five days (Array with five object)
  location.getFiveDaySummary(cb);
  // Current conditions
  location.getCurrentSummary(cb);
  // Weather anytime from now till future
  location.getForecastForTime(time, cb);
}, [VERSION]);

Weather JSON Format

Format is somewhat inspired by that of forecast.io service. Not all fields will always be available. Fields that no data was retrieved for contain the null value;
