Mo' models mo' problems

One of the best things about Vue templates is the special v-model prop. v-model allows you two quickly map prop getters and setters without breaking unidirectional data flow. Props down, events up.

Distraction-less user interfaces: Delayed transient states

I have a specific pet peeve with user interfaces: things that draw my attention when they don’t need to. In any graphical interface, movement is distraction. Our eyes are naturally drawn to anything in motion.

Motion is a powerful tool. We can abuse this distraction to attract our users to a certain place: a notification, an added list item after a background refresh, etc. Let’s look into the movement behind a form submission. Below are three dummy forms, each with a different server response time.

Vue templates in JSX

In my most recent project at work, I’m experimenting with JSX templates in Vue. Vue offers first-party support for JSX with near-zero configuration, but it doesn’t seem to be commonly used in the ecosystem.

Code splitting with Laravel Mix

Code splitting is bundler feature—if you’re using Laravel Mix, you’re bundling your assets with Webpack—that allows you to split application scripts in multiple files. These can then conditionally be loaded at a later stage.

Design Details: Incremental Correctness with Guillermo Rauch

In a recent Design Details podcast, Guillermo Rauch (@rauchg) shares his thoughts on the web, design, the value of code, type systems, cryptocurrencies and much much more.

I have a lot of respect for Guillermo’s philosophies, and what he’s building with Zeit. An early quote from the interview (paraphrased):

I’ve always had this passion for the hyperlink. My whole thesis is everything that has not yet been hyperlinked, will be hyperlinked. If we step back and take that thesis a little further—you look at GitHub and they but a hyperlink on everything. They put a hyperlink on every per-character diff of your codebase. Every line of code. Every changeset. Everything.

Server side rendering JavaScript from PHP

Server side rendering is a hot topic when it comes to client side applications. Unfortunately, it’s not an easy thing to do, especially if you’re not building things in a Node.js environment.

I published two libraries to enable server side rendering JavaScript from PHP: spatie/server-side-rendering and spatie/laravel-server-side-rendering for Laravel apps.

Let’s review some server side rendering concepts, benefits and tradeoffs, and build a server renderer in PHP from first principles.

Diving into requestAnimationFrame with Benjamin De Cock

I love this post! requestAnimationFrame is a primitive browser API that doesn’t sound too interesting at first, but once you’ve grasped some basic concepts, it becomes an extremely powerful tool for dealing with animations in JavaScript.

At its core, requestAnimationFrame doesn’t do much: it’s basically just a method that executes a callback. In fact, there are very few differences between doing requestAnimationFrame(doSomething) and doSomething(). So, what’s so special about it? I’m glad you asked! In short:

  • requestAnimationFrame schedules the callback call on the next repaint
  • requestAnimationFrame passes the callback the current time

There are a few other distinctions, but these are the main benefits. Now, requestAnimationFrame doesn’t create an animation on its own, it’s the sequence of successive callbacks that will make things move on the screen.

My favorite part: since a large part of animating with requestAnimationFrame consists of composing small mathematical expressions, you can apply all sorts of functional programming tricks to your code.

What's in our .babelrc?

A lot has been going in in JavaScript the past few years. One of my favorite things has been the usage of babel, which allows us to write future JavaScript syntax today. The babel ecosystem has tons of plugins and configuration options, I’d like to elaborate on our usage at Spatie.

Using registered event listeners as conditionals in Vue

Today I was writing a form component that needed an optional back button. Since the form component is generic, the back button could point to anything.
