Introduction In this blog, I would like to share my opinion on how we, as front-end developers, often make projects unnecessarily complex. We often think we’re doing the right thing, but are we?

Most Nuxt.js and Vue applications use the official @vue/test-utils which includes clever methods and options to help you write the best unit tests for your application. You probably tried to test your asyncData or fetch hook but couldn't succeed. This article explains why this is, but also…

A nice trick to let editors edit content without wasting any time waiting on the page to reload. The problem Unfortunately this comes with an issue; frontend frameworks.…
Tools zoals Gulp en Grunt helpen front-end developers bij de ontwikkeling van websites of webapplicaties. De termen Concat, Uglify en Minify worden door beide tools gebruikt, maar wat betekenen deze termen en nog belangrijker, wat kunnen we ermee?ConcatConcat komt van het woord concatenation, wat letterlijk vertaald betekent dat tekenreeksen op elkaar worden aangesloten.

Een reguliere expressie biedt een gestructureerde methode om patronen te definiëren waarmee een computer tekst kan identificeren. Deze methodiek volgt een formele syntaxis, die deels gestandaardiseerd is.
