Weather information for node.js

Forecast - Weather information for Node.js =================================================

The aim of this module is to provide a common API for multiple weather providers and to return the results as a normalized Object.

Currently the only provider available is Forecast.io

$ npm install --save forecast

To use the forecast.io API you will need an API key which is available from https://developer.forecast.io/

// Require the module 
var Forecast = require('forecast');
 
// Initialize 
var forecast = new Forecast({
  service: 'forecast.io',
  key: 'your-api-key',
  units: 'celcius', // Only the first letter is parsed 
  cache: true,      // Cache API requests? 
  ttl: {            // How long to cache requests. Uses syntax from moment.js: http://momentjs.com/docs/#/durations/creating/ 
    minutes: 27,
    seconds: 45
    }
});
 
// Retrieve weather information from coordinates (Sydney, Australia) 
forecast.get([-33.8683, 151.2086], function(errweather) {
  if(err) return console.dir(err);
  console.dir(weather);
});
 
// Retrieve weather information, ignoring the cache 
forecast.get([-33.8683, 151.2086], true, function(errweather) {
  if(err) return console.dir(err);
  console.dir(weather);
});
