coback

Occasionally you find yourself in a position where thunks don't quite work, such as:

var obj = new FakeObject(callback);
obj.doSomething();
obj.execute(); // now... how do I yield on the callback at this step?

Coback solves that by creating a callback which can be passed to traditional-style functions, but still yielded on at a later time.

var coback = require('coback');

// just call coback to create the callback function
var callback = coback();

// pass the callback to your function/constructor
var obj = new FakeObject(callback);
obj.doSomething();
obj.execute();

// when you're ready to wait for the result, yield on the result property
var result = yield callback.result;

Built to work with co but likely works with other frameworks.

Install

npm install coback
