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.

function mapValues(obj, fn) {
  return Object.keys(obj).reduce((result, key) => {
    result[key] = fn(obj[key], key);
    return result;
  }, {});
}

function pick(obj, fn) {
  return Object.keys(obj).reduce((result, key) => {
    if (fn(obj[key])) {

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

'use strict';

import {Router5, RouteNode} from 'router5';
import logger from '../logger';

// The set of valid sink functions includes synchronous state-affecting router functions that do not require a callback
// and which do not have a significant return value other than the router object itself.
const validSinkFuncs = ['add','addNode','canActivate','deregisterComponent','navigate','registerComponent','setOption','start','stop'];

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
