posted in JavaScript on 2019-11-01   javascript iterator skills console log javascript const lastname object react parts user method

Just recently I became a fan of the iterable protocol. I knew about it for some time now but never actually integrated it on my own. I ended up using it to provide a nice API for one of my libraries and I thought that this approach worth sharing.

Rethinking the Redux API

posted in JavaScript on 2019-09-10   redux const state login username password authenticated action function reducer

I really like Redux. I Love its ideas. The reducers for example - small pure functions that apply changes without side effects are nice way to model the mutations in the state. Redux also teaches us to use the one-direction data flow which makes our apps more predictable and stable. These two things fits well for what we are doing on the front-end - building user interfaces.

Of course there is nothing perfect and Redux as every other library has its own problems. In this article I want to explore some ideas for new APIs that will help solving the problems that I encounter. I’ll be happy to see your comments below.

Why and how I built my own alternative of the GitHub's UI

posted in JavaScript on 2019-04-25   igit code github context time api code review roger app

I'm using Git and GitHub in particular a lot. And when I say a lot I really mean all the time. Recently I tracked a week of work and found that 62% of my working time goes into code reviews. Sometimes I'm checking out a branch locally and trying stuff but really most of my time goes into github.com. I spent some time analyzing why the code review process is so time consuming for me. I identified couple of reasons, made a tool and changed some of my habits. In this article I'll show you how I improved my code review speed and lower the time to 38%.

Jolly Roger - a 2KB micro-framework based on React hooks API

posted in JavaScript on 2019-04-20   time roger const state return function usestate yohoho action

The hooks API is a wonderful idea. There are some slick patterns involved that push the React development to a more functional approach. I'm interested in trying that new API and decided to use it for my latest project. However, after a couple of days, it looked like I can't build my app only with hooks. I needed something else. And that's mainly because each hook works on a local component level. I can't really transfer state or exchange reducers between the components. That's why I created Jolly Roger. It has similar helpers but works on a global app level.
