Web Components Club – A journal about learning web components

Andy Bell is documenting is journey of getting to grips with web components. I think it’s so valuable to share like this as you’re learning, instead of waiting until you’ve learned it all—the fresh perspective is so useful!

The React is “just” JavaScript Myth - daverupert.com

In my experience, there’s no casual mode within React. You need to be all-in, keeping up with the ecosystem, or else your knowledge evaporates.

I think Dave is right. At this point, it’s possible to be a React developer exclusively.

React is an ecosystem. I feel like it’s a disservice to anyone trying to learn to diminish all that React entails. React shows up on the scene with Babel, Webpack, and JSX (which each have their own learning curve) then quickly branches out into technologies like Redux, React-Router, Immutable.js, Axios, Jest, Next.js, Create-React-App, GraphQL, and whatever weird plugin you need for your app.

And, as Jake points out, you either need to go all in or not at all—you can’t really incrementally add Reactness to an existing project.

UTC is Enough for Everyone, Right?

A wonderful—and humorous—deep dive into all things time-related.

Building a calendar sucks. Like there’s really cool shit you can do, since every calendar out there today is basically straight outta 2005, but at the end of the day you’re stuck dealing with all of the edge cases that all your dork friends have warned you about since the dawn of time. (Like literally, the dawn of time is a separate edge case you have to account for as well.)

This also contains a well-deserved shout-out to ISO 8601:

ISO 8601 is one of my favorite standards and/or RFC out there. And yes, you should definitely have a favorite.

I do have a favourite RFC—ask me about it sometime over a beer.

Solving Life’s Problems with CSS | CSS-Tricks

It turns out that Diana Smith isn’t just a genius with CSS—she’s a fantastic writer too. This post is somehow heartfelt and lighthearted at the same time. It’s also very humorous, but beneath the humour there’s an excellent point here about the rule of least power …and doing things the long, hard, stupid way.

Because something about those limitations just calls to me. I know I’m not alone when I say that a rigid set of restrictions is the best catalyst for creativity. Total artistic freedom can be a paralyzing concept.

That can sometimes be the case with programming. If you have the most powerful programming languages in the world at your disposal, it starts to seem natural that you should then have no difficulty solving any programming problem. With all these amazing tools offering countless solutions to solve the same problem, it’s no wonder that we sometimes freeze up with information overload.

Push notifications explained using astrology. But don’t worry, there’s also some code, just in case you prefer your explanations to also include models that actually work.

CSS and Markup in Javascript is an Evolutionary Dead End

The bet to make is that we’re going to see more use of specialized languages. And HTML and CSS are the grandaddy specialized languages that have enough social consensus and capital investment to be the seeds of the next generation.

Easy Toggle State

I think about 90% of the JavaScript I’ve ever written was some DOM scripting to handle the situation of “when the user triggers an event on this element, do something to this other element.” Toggles, lightboxes, accordions, tabs, tooltips …they’re all basically following the same underlying pattern. So it makes sense to me to see this pattern abstracted into a little library.

Meet swup

This looks like a handy library for managing page transitions on sites that are not single page apps.

Here’s the code.

I’ve said it before and I’ll say it again, but I really think that this handles 80% of the justification for using a single page app architecture.

The Slow Death of Internet Explorer and the Future of Progressive Enhancement · An A List Apart Article

Oliver Williams makes the case—and shows the code—for delivering only HTML to old versions of Internet Explorer, sparing them from the kind of CSS and JavaScript that they can’t deal with it. Seems like a sensible approach to me (assuming you’re correctly building in a layered way so that your core content is delivered in markup).

Rather than transpiling and polyfilling and hoping for the best, we can deliver what the person came for, in the most resilient, performant, and robust form possible: unadulterated HTML. No company has the resources to actively test their site on every old version of every browser. Malfunctioning JavaScript can ruin a web experience and make a simple page unusable. Rather than leaving users to a mass of polyfills and potential JavaScript errors, we give them a basic but functional experience.

Super-powered layouts with CSS Variables + CSS Grid by Michelle Barker on CodePen

This article is about using custom properties and CSS grid together, but I think my favourite part is this description of how custom properties differ from the kind of variables you get from a preprocessor:

If you’re familiar with Javascript, I like to think of the difference between preprocessor variables and CSS Variables as similar to the difference between const and let - they both serve different purposes.

How to display a “new version available” of your Progressive Web App

This is a good walkthrough of the flow you’d need to implement if you want to notify users of an updated service worker.

I Used The Web For A Day With JavaScript Turned Off — Smashing Magazine

Following on from Charlie’s experiment last year, Chris Ashton has been assessing which sites rely on JavaScript, and which sites use it in a more defensive, resilient way. Some interesting results in here.

A good core experience is indicative of a well-structured web page, which, in turn, is usually a good sign for SEO and for accessibility. It’s usually a well designed web page, as the designer and developer have spent time and effort thinking about what’s truly core to the experience. Progressive enhancement means more robust experiences, with fewer bugs in production and fewer individual browser quirks, because we’re letting the platform do the job rather than trying to write it all from scratch.

HTML5 Constraint Validation

The slides from a presentation by Drew on all the functionality that browsers give us for free when it comes to validating form inputs.

Half the battle of the web platform is knowing what technology is out there, ready to use. We’re all familiar with the ability to declare validation constraints in our HTML5 forms, but were you aware there’s a JavaScript API that goes along with it?

Building Progressive Web Apps | nearForm

It is very disheartening to read misinformation like this:

A progressive web app is an enhanced version of a Single Page App (SPA) with a native app feel.

To quote from The Last Jedi, “Impressive. Everything you just said in that sentence is wrong.”

But once you get over that bit of misinformation at the start, the rest of this article is a good run-down of planning and building a progressive web app using one possible architectural choice—the app shell model. Other choices are available.

Here’s an article from last year that gives a really good introduction to service workers and provides a plug-in for the Craft CMS.

Going Offline: Designing An Ideal Offline Experience With Service Workers By Jeremy Keith

Here’s a great even-handed in-depth review of Going Offline:

If you’re interested in the “offline first” movement or want to learn more about Service Workers, Going Offline by Jeremy Keith is a really gentle and highly accessible introduction to the topic. At times, it even felt “too gentle”, with Keith taking a moment here and there to explain what a “variable” is and what “JSON” (JavaScript Object Notation) is. But, this just goes to show you the unassuming and welcoming mindset behind writing a book like this one.
