Whenever we find a severe bug that is caused by an error in a complicated piece of code, in my experience, the first instinct is that better documentation is needed. So that the next time we need to debug the code, at least we know what it is supposed to do. I argue that this is a waste of time...

Out of the box, Cypress offers an amazing live-reloading feature. But there is one caveat: live-reloading only works when changing test code, not when updating the application code. Nowadays, we are used to live-reloading in the browser thanks to webpack hot module replacement (HMR) and other fantastic development tools like Vite or Snowpack. If we had something similar in Cypress, practicing TDD would be a lot easier...

When testing components (e.g., Vue or React) or regular JavaScript modules, we typically want to decouple our test code from the implementation as much as possible.

Tailwind CSS is a divisive issue in the web development world: some love it, others love to hate it. This article is about one specific feature of Tailwind CSS: its antifragility...

Whenever you feel the need to access global state or globally injected plugin methods or global anything for that matter, often it is a sign that the component you're working on is doing too much...

Props Down / Events Up is the standard paradigm for communication between parent and child components in Vue.js. React, on the other hand, uses callback functions instead of events. But why is using callbacks considered an anti-pattern in the Vue.js world? And what are the conceptual differences...
