Dennis Claassens

There are a whole lot of best practices out there, but when looking at how to test controlled components I was a bit stumped. There seem to be four major “routes” which I would like to cover in this blog post.

Arnout Boks

If everyone jumps off a bridge, would you jump after them? Well, in that case there certainly must be some advantages to jumping off the bridge. Read more about our strategic choice for adopting existing open source solutions rather than maintaining our own.

Matthijs Bon

So you have probably heard of TypeScript and the awesome features it brings, such as interfaces, variable typing and more. Maybe you have even heard of generics, and more advanced types, such as the Index Types and Mapped Types. In this blog I want to show you how advanced types helped us get better autocompletion in more complex situations.

Arnout Boks

A long-standing objection to making bulk changes to code using automated tools is that it clutters the output of git blame. With git 2.23, this does not have to be the case anymore!

Reducing the size of an iconfile

18-09-2019

Yelitza Jansen

We love our icons, we love their shape, colours, their meaning and purpose, but we kind of hate their weight. For all our icons we had a separate SVG which means that all the icons had to be loaded in those colours. 130 x 7 colours resulted in one big file. That data needed to be loaded in our application every time. This wasn’t maintainable therefore we needed to look for a better solution.
