What

nextback makes sure your callbacks don’t return immediately by wrapping them in a setImmediate or nextTick.

What you shouldn’t do

var doAsync = function(cb) {
  if (somethingIsWrong) {
    return cb(new Error("Crap"));
  }
  doWork(function(data){
    cb(null, data);
  });
};

What you should do

var nextback = require('nextback');

var doAsync = function(cb) {
  cb = nextback(cb);

  if (somethingIsWrong) {
    return cb(new Error("Crap"));
  }
  doWork(function(data){
    cb(null, data);
  });
};
