  somethingAsync("some input data", function(err, data) {
    if (err) return neder.reject("some reason");
    neder.resolve(data);
  });
  return neder;
};

Neder#then#

accepts a callback with the format of function(data, next). next evaluates your next block. pass it your errors and data: next(err, data)

myAsyncMethod().then(function(data, next) {
  // Do whatever and call "next" to pass your data to the next block
  next(null, "some data");
});

Shorthand Neder.amen function#

Neder.amen(function(next) {
  doSomethingAsync("next", "is a callback", "with next(err, data) format", next);
}).then(function(data, next) {
  doSomethingElse("now you can use", data, "when you pipe it", next);
}).then(function(data, next) {
  // You can call "next" explicitly:
  doSomething(function(response) {
    if (response.isError) return next(response.error);
    next(null, response.data);
  });
}).then(function(data, next) {
  console.log("results: ", data);
});
