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 […]
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 […]
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”.

Let’s say you have several functions that return a promise: function act1() { return new Promise((resolve, reject) => { // do something that might reject... resolve(); }); } It’s easy […]
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 […]
