Node package for random.org API

This package presumes your API key is stored in an environment variable called RANDOM_API_KEY. It will use dotenv to load the api key from a file.

The available functions are:

• generateIntegers(n, min, max, [replacement, base,] callback)
• generateDecimalFractions(n, decimalPlaces, [replacement,] callback)
• generateGaussians(n, mean, standardDeviation, significantDigits, callback)
• generateStrings(n, length, characters, [replacement,] callback)
• generateUUIDs(n, callback)
• generateBlobs(n, size, [format,] callback)
• getUsage(callback)

Respecting the advisoryDelay in the response needs to be handled by the callback.

Note that I've really only used generateIntegers so far. Tests and such are in progress.

Example

function(n, callback){
  function callRandomOrgApi(){
    randomorg.generateIntegers(n, 1, 10, RandomOrgCallback);
  };

  function RandomOrgCallback(err, body){
    if(!_.isNull(err)){
      // something went wrong, call the fallback
      fallback();
    } else {
      setTimeout(semaphore.leave, body.advisoryDelay);
      callback(body.random.data);
    }
  };

  function fallback(){
    roll = _.map(random.dice(10, n), function(k){return k-1;});
    callback(roll);
  }

  semaphore.take(callRandomOrgApi, fallback);
}
