A wrapper that detects if node-style callbacks are used. After the wrapper is applied, if a callback is supplied then it is used, but if a callback is missing (i.e. the last parameter is not a function), then a BlueBird promise is used.

Use with regular objects:

var promiqueen = require('promiqueen');
 
var context = {
    method: promiqueen(function(arg,callback) {
        callback(err,data);
    })
};
 
// ...
 
context.method('crown',function(err,data) {
    if ( err ) console.warn(err);
    console.log('data',data);
});
 
context.method('crown').then(function(data) {
    console.log('data',data);
}).catch(function(err) {
    console.warn(err);
});

Use with classes:

var promiqueen = require('promiqueen');
 
var SomeClass = function() {};
 
SomeClass.prototype.method = promiqueen(function(arg,callback) {
    callback(err,data);
});
 
// ...
 
var instance = new SomeClass();
 
instance.method('crown',function(err,data) {
    if ( err ) console.warn(err);
    console.log('data',data);
});
 
instance.method('crown').then(function(data) {
    console.log('data',data);
}).catch(function(err) {
    console.warn(err);
});
