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.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Notice

This script is no longer required with Docker for Mac which includes an option to run Docker at startup and doesn't use docker-machine to administer the local Docker engine.

Requirements

Docker Machine + Docker
curl
A Virtualbox-driven Docker Machine called "default" docker-machine create --driver virtualbox default (this is the default with Docker toolkit).

This is an auth example (WIP)

react + redux + RR

It uses https://gist.github.com/iNikNik/3c1b870f63dc0de67c38 for stores and actions.

1) create redux

const redux = createRedux(state);

2) get requireAccess func => bindCheckAuth to redux

	"Accepts a collection of channels, an optional selector function f and an option output
	channel. Returns a channel with the latest values of the input values combined by the
	selector function. If no selector function is specified, a vector will be returned.
	The output channel closes when any of the input channels closes.
	Inspired by http://rxmarbles.com/#combineLatest"
