This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.

The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

In this gist I would like to describe an idea for GraphQL subscriptions. It was inspired by conversations about subscriptions in the GraphQL slack channel and different GH issues, like #89 and #411.

Conceptual Model

At the moment GraphQL allows 2 types of queries:

query
mutation

Reference implementation also adds the third type: subscription. It does not have any semantics yet, so here I would like to propose one possible semantics interpretation and the reasoning behind it.

	* This is a pretty good set, especially considering that many emacs bindings
	* such as C-o, C-a, C-e, C-k, C-y, C-v, C-f, C-b, C-p, C-n, C-t, and

	* BEWARE:
	* This file uses the Option key as a meta key. This has the side-effect

	# Hey Chi-Town, I made this rake task, and it has saved some of us a lot of time.
	# Some people asked me to post it, so here it is:

	desc 'You only live once'
	task 'yolo' => ['db:drop', 'db:create', 'db:migrate', 'db:seed'] do
	exec "bundle exec shotgun config.ru"
	end

	# NOTE: If db:create or db:drop use "exec" instead of "system", this will not work.
	# If you decide to fix this, google why this happens first.
