Source code for the npm module that scrapes snow-forecast.com. This is an unofficial scraper.
Enough chit-chat, just show me how to use it in 5 lines.
var snow = require('snow-forecast-sfr');
snow.parseResort('Tignes', 'mid', function(json){
//json contains the forecast JSON
});Currently snow-forecast decides whether to show units in metric or imperial based on where the request is coming from. If you need to specify whether the response should be in imperial or metric units simply do the following:
snow.parseResort('Tignes', 'mid', function(json){
//json contains the forecast JSON
}, { isMetric: false });By passing in an options hash with the value for the isMetric key set to true for metric, or false for imperial.

parseResort takes three parameters, the name of the resort (as is found on snow-forecast.com), the elevation ('low', 'mid' or 'top'), a callback where you specify what to do with the returned object and an optional options object where you can specify the units.
- Insufficient parameters - You haven't passed the proper number of parameters into the parseResort method.
- Invalid page 404 - snow-forecast.com returned a 404, usually because the resort name you gave differs to how it's used on snow-forecast.com
- Remote server error - Unable to connect to snow-forecast.com. Check whether the network is operating properly. Alternatively, the site may be down.
- Parse error - The parsing has failed. This should never happen.
- JSON Construction error - We were unable to build the forecast. This should never happen.
This is an unofficial module, and thus if snow-forecast decide to change the structure of their DOM then this will most likely break. We'll do our best to get it back up to scratch but caution beware. This issue affects all scrapers though.
In order to run the suite of jasmine tests run the following code:
npm testWe rely on the following npm modules:
We have a few ideas but we would love to hear any you encounter in. Feel free to raise an issue and let us know :)
