The Dark Sky Cold Fusion SDK by Danny Cork allows developers to use CFML in the construction of weather foresting applications. The SDK communicates with the Dark Sky API, formerly Forecast.io API.

Calls to the SDK’s getWeather function initiates optional API key validation and the required latitude and longitude coordinates.
