I thought it would be pertinent to respond to some points presented by Andrey "Rarst" Savchenko in recent post Progressive Enhancement.

Progressive Enhancement

Unlike Rarst, I don't value progressive enhancement very highly and don't agree it's a fundamental principle of the web that should be universally employed. Quite frankly, I don't care about not supporting JavaScript, and neither does virtually anyone else. It's not that it doesn't have any value, or utility - but in a world where we don't have unlimited resources and time, one has to prioritise what we'll support and not support.

I'm a proponent of putting my ideas and creations into the world for people to make use of; and if I had to cover 100% of use cases for doing that, I wouldn't put much out there. I'm fine with losing the 1.1% of

Huh?

So basically FlowType doesn't know about CSS Modules, a really handy way of dealing with the plagues of CSS in codebases (global variables and dependency wackiness mainly).

What WebPack allows us to do is "require" CSS files and use their class names:

import styles from "my_styles.css";
import React from "react";

let Rx = require(`rx`)

function makeRequestProxies(drivers) {
  let requestProxies = {}
  for (let name in drivers) {
    if (drivers.hasOwnProperty(name)) {
      requestProxies[name] = new Rx.ReplaySubject(1)
    }
  }
  return requestProxies

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

Observable React elements with RxJS

Note: if you want to skip history behind this, and just looking for final result see: rx-react-container

When I just started using RxJS with React, I was subscribing to observables in componentDidMount and disposing subscriptions at componentWillUnmount.

But, soon I realised that it is not fun to do all that subscriptions(that are just updating property in component state) manually, and written mixin for this...

Later I have rewritten it as "high order component" and added possibility to pass also obsarvers that will receive events from component.

Usage

1. npm install babel-loader imports-loader webpack --save
2. Create webpack.config.js
3. Move index.ios.js to src/index.ios.jsx
4. webpack --watch

Example

src/index.ios.jsx
