Change the marker of a list to any character with list-style-type: <string>

Since CSS Level 2, CSS list-style-type has supported keywords like disc or decimal to define the appearance of the list item marker. Landing in Chrome 79, and also available in Firefox ever since version 39, is the ability to set it to an arbitrary string. Here’s a pen that demonstrates its behavior / usage: Let’s […]

Programmatically add scripts to `package.json` with `npm-add-script`

Recently I needed to automate the addition of the addition of a script defined in a package.json‘s scripts section. To do this I used npm-add-script (an older, but still functioning project), along with the aforementioned npx. For example, to add a script labelled start with the contents webpack-dev-server –config ./config/webpack.config.babel.js –env.MODE=development –open –hot, I use: […]

ESNext: Proposals to look forward to (Full Stack Europe)

I’m currently in Antwerp for the first edition of Full Stack Europe, “The conference for the whole team”. Earlier this week I guided a workshop “React from Scratch”. After a small Lightning Talk yesterday on “JavaScript Yellow”, I today did a full talk named “ESNext: Proposals to look forward to” With the yearly ECMAScript releases […]

Pure CSS Scroll Shadows (Vertical + Horizontal)

A long time ago (2012!), Lea Verou shared a way on how to add scrolling shadows to containers that needs scrolling. Using those shadows in a scroll container is a great UX thing, as they visually tell the user that the content is scrollable. Her code however, only worked with containers that scroll vertically. Based […]

Ship legacy JavaScript and CSS files in a Webpack Project with webpack-merge-and-include-globally

One of the projects that I’m working on is quite reliant on jQuery and Bootstrap. As we’re introducing new features (such as a few React-based components, and Stylus for CSS) in said project, we’ve also introduced Webpack into it. Now, we don’t want to run jQuery nor Bootstrap through Babel (using Webpack), but we want […]

Simple Scroll Snapping Carousel (Flexbox Layout / Grid Layout)

Here are two small scroll-snapping carousels that I made. In the top one the items are laid out using CSS Flexbox, whereas the second one uses CSS Grid. The code also works fine with arbitrarily sized .scroll-items elements, they don’t need to have the same width. ℹ️ Want to now more about scroll snapping? Check […]

Working with symlinked packages in PHP

When developing a PHP library/package, you most likely also have a project on disk that consumes said library. Take a WordPress plugin for example: to test it, you need a WordPress installation — both are linked but separate projects. To speed up development you can tell Composer to use the local version of the package, […]

Overriding the PHP version to use when installing Composer dependencies

If you have a (legacy) PHP project running on a legacy server (running PHP 5.4.27 for example), but are locally developing with a more modern PHP version (PHP 7.4 for example), you might end up installing dependencies that are not compatible with the PHP version on the server. To bypass this, you can tell Composer, […]

ESNext: Immutable Datastructures in JavaScript with Records & Tuples

A new ECMAScript Proposal that I’m looking forward to is this one which introduces the Record and Tuple value types. In short: Records are immutable Objects that are compared by value. Tuples are immutable Arrays that are compared by value. The proposal is currently Stage-1. Stage-1? Stage-4? 💁‍♂️ The TC39 Committee, which is concerned with […]
