TypeScript over React PropTypes

React v15.5.0 is here and the React.PropTypes module gives a deprecation warning. Moving forward you’ll find it in it’s own package. I’ve always used React PropTypes because it seemed like the ‘right way’ to do things. Runtime validation has obvious value but in my experience there are three big negatives to it: PropTypes are tedious to write PropTypes […]

The Magic of Service Workers

They’re a thing. Google describes them as a “technical foundation”. What I’ve learnt is that a service worker is a JavaScript file. It runs in it’s own little world behind a website. That means it can’t access the DOM. What it can do is proxy network requests and access a storage cache. I’m sure they can do […]

I watched Iron Fist and coded CSS 👈

They have nothing in common. Well, aside from entertaining my weekend. I’m just bad at blog titles and I’m fed up of writing nonsense like “CSS modularity; theory and practice”.

React as a Static Site Generator

Hacks and plumbing to get Metalsmith plugins working my way didn’t helped. Time for a new project! Abstract: rebuild my website using React as the template engine for a bespoke static […]

Working with Promises

JavaScript promises are a handy way to write asynchronous code. It’s common to have multiple promises resolve in parallel or series. Let’s say you have several functions that return a promise: It’s easy to run these functions in parallel: But how to run them sequentially? One way is to nest the promises: Nesting gets uglify real fast and some […]

My thoughts on React

I’ve been playing with React for some time now. React is: “A JavaScript library for building user interfaces”. Unlike other libraries something about React just clicked with me. Back in October a client project came along that presented a golden opportunity to develop a web app. I decided to use React, and I now consider myself comfortable […]
