Effective Promise patterns in node 6 and beyond.
Promises can be an effective way of avoiding a tangled mess of nested callbacks, especially with the introduction of async/await. However, it's not always easy to integrate existing, callback-based modules with newer Promise-based ones and it's an even larger task to migrate existing code to use Promises.

We faced this exact problem at Mixmax ( where we were torn between existing infrastructure using callbacks and the strong appeal of switching to Promises for future development. As a result we developed a few libraries (promise-callbacks (, promise-pool (, promise-iterate ( and techniques (using transpilation ( that allowed us to immediately integrate Promises and async/await into existing code without drastic, bottom-up changes.

I'll be sharing these techniques with examples as well as some tips, so you don't have to write another callback.
