265b lib for building pure functional state machine components.
View *


A tiny (265 byte) utility to create state machine components using two pure functions.

🔥 JSFiddle Demo


The API is a single function that accepts 2 pure functions as arguments:


Sony Bravia HTTP API

The sony bravia has a HTTP API interacted with using a Pre-Shared key. There's a more complex auth flow but I've not described it here.

There wasn't any documentation, so I've written some. If you're a TV integrator don't read this, you'll laugh. I'm probably just getting confused by UPnP.

Disclaimer: I've only tested this on my TV, which is a KDL-50W829B. Your TV might not have all of the services; see Available services section for how to discover what your TV supports.

Proposal for lightning talk at ReactiveConf 2017: What is RNRF (react-native-router-flux)?

What is RNRF (react-native-router-flux)?

React Native is great product but lacks for stable, intuitive and easy navigation API during many years. Every year we see new, better API: Native Navigator, ex-Navigator, NavigationExperimental, ex-Navigation, wix native navigation, airbnb native navigation, ReactNavigation...

Once I've started React Native development, in 2015, I created RNRF - simple API for easy navigation. It was clear that better navigation instruments will come later but I didn't want to change my code again and again to switch for better API. Every new major version of RNRF is based on different navigation framework and mostly preserves own API.

Another goal was to represent all navigation flow within one place in clear, human-readable way - similar to iOS Storyboards concept. This way other engineers could understand your app flow faster.

#ReactiveConf 2017 Lightning Talk Submission: JavaScript Slam Poetry

TL;DR: If you want to see me perform a spoken word poem about JavaScript in front of 1000 people (and on video), please ⭐️ star this gist. If you're on mobile, you'll need to request desktop site.

JavaScript Slam Poetry

Javascript! Slam! Poetry!


FWIW: I didn't produce the content presented here (the outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.

Effective Engineer - Notes

What's an Effective Engineer?


A top-level App component returns <Button /> from its render() method.

  1. What is the relationship between <Button /> and this in that Button’s render()?

  2. Does rendering <Button><Icon /></Button> guarantee that an Icon mounts?

  3. Can the App change anything in the Button output? What and how?

SUIT CSS naming convention for React.js application

Recently CSS has got a lot of negativity. But I would like to defend it and show, that with good naming convention CSS works pretty well.

My 3 developers team has just developed React.js application with 7668 lines of CSS (and just 2 !important). During one year of development we had 0 issues with CSS. No refactoring typos, no style leaks, no performance problems, possibly, it is the most stable part of our application.

Here are main principles we use to write CSS for modern (IE11+) browsers:


Type Safe JSON Decoding in Elm

The power of a Static Typed language can seem magical at first. But the goal here is to take a tiny peak behind that curtain.

Elm's implementation of JSON parsing is type safe and how it achieves that can seem like a mystery. Even though I got the code to work, it took me a while to fully understand how it works.

I'm writing it down here for 2 reasons. To help others gain a greater understanding of Types and so I don't forget what I learned.

Word of Caution

HTML5 <details> in GitHub

Using <details> in GitHub

Suppose you're opening an issue and there's a lot noisey logs that may be useful.

Rather than wrecking readability, wrap it in a <details> tag!

 <summary>Summary Goes Here</summary>
You can’t perform that action at this time.
