A timely reminder:

The minimum dependency for a web site should be an internet connection and the ability to parse HTML.

Workshop Countdown Clock

Here’s a nifty little progressive web app that Trys whipped up so that Clearlefties running workshops remotely still get to have their beloved countdown clock.

Same HTML, Different CSS

Like a little mini CSS Zen Garden, here’s one compenent styled five very different ways.

Crucially, the order of the markup doesn’t consider the appearance—it’s concerned purely with what makes sense semantically. And now with CSS grid, elements can be rearranged regardless of source order.

CSS is powerful and capable of doing amazingly beautiful things. Let’s embrace that and keep the HTML semantical instead of adapting it to the need of the next design change.

Progressive enhancement doesn’t have to be hard - Levi McGranahan

It’s wild because in engineering terms this question, how does it fail?, should be the first one we ask, but oftentimes it is never even considered in front-end development. A good example is most client-side JS frameworks that render the entire UI in the browser, how would your app or site fail in that situation?

N26 and lack of JavaScript | Hugo Giraudel

JavaScript is fickle. It can fail to load. It can be disabled. It can be blocked. It can fail to run. It probably is fine most of the time, but when it fails, everything tends to go bad. And having such a hard point of failure is not ideal.

This is a very important point:

It’s important not to try making the no-JS experience work like the full one. The interface has to be revisited. Some features might even have to be removed, or dramatically reduced in scope. That’s also okay. As long as the main features are there and things work nicely, it should be fine that the experience is not as polished.

Smaller HTML Payloads with Service Workers — Philip Walton

This is a great progressive enhancement for performance that uses a service worker to combine reusable bits of a page with fresh content. The numbers are very convincing!

Alas, the code is using the Workbox library, but figuring out the vanilla code to write shouldn’t be too tricky seeing as Philip talks through his logic step by step.

Making a ‘post-it game’ PWA with mobile accelerometer API’s | Trys Mudford

I made an offhand remark at the Clearleft Christmas party and Trys ran with it…

How creating a Progressive Web App has made our website better for people and planet

Creating a PWA has saved a lot of kilobytes after the initial load by storing files on the device to reuse on subsequent requests – this in turn lowers the load time and carbon footprint on subsequent page views, making the website better for both people and planet. We’ve also enabled offline access, which significantly improves user experience for people in areas with patchy connections, such as mobile users on their commute.

Move Fast & Don’t Break Things | Filament Group, Inc.

This is the transcript of a brilliant presentation by Scott—read the whole thing! It starts with a much-needed history lesson that gets to where we are now with the dismal state of performance on the web, and then gives a whole truckload of handy tips and tricks for improving performance when it comes to styles, scripts, images, fonts, and just about everything on the front end.

A Non-Business Case for Supporting Old Browsers « Texte | ovl – code & design

Supporting Internet Explorer 11 doesn’t mean you need to give it the same experience as a modern browser:

Making sure (some of) your code works in older browsers, does not mean all functionality has to work everywhere. But, mind you, ninety percent of web development means putting text and images in boxes.

And to be honest, there is no reason to not enable this everywhere. Same for form submissions. Make it boring. Make it solid. And sprinkle delight on it.

The Layers Of The Web - Jeremy Keith on Vimeo

Thanks to the quick work of Marc and his team, the talk I gave at Beyond Tellerrand on Thursday was online within hours!

I’m really pleased with how this turned out. I wasn’t sure if anybody was going to be interested in the deep dive into history that I took for the first 15 or 20 minutes, but lots of people told me that they really enjoyed that part, so that makes me happy.

JavaScript isn’t always available and it’s not the user’s fault by Adam Silver

It’s not a matter of if your users don’t have JavaScript—it’s a matter of when and how often.

The answer to that is around 1% of the time.

If you had an application bug which occurred 1% of the time, you’d fix it. No team I’ve come across would put up with that level of reliability.

The same goes for JavaScript. It’s not about people who turn it off. It’s about the nature of the web itself.

Using ES6 modules for progressive enhancement | Blog | Decade City

It looks like modules could be a great way to serve modern JavaScript to modern browsers, and serve polyfills or older code to older browsers.

That unusual behaviour I wrote about with the Web Share API in Safari on iOS is now officially a bug—thanks, Tess!

The “P” in Progressive Enhancement stands for “Pragmatism” - Andy Bell

With a Progressive Enhancement mindset, support actually means support. We’re not trying to create an identical experience: we’re creating a viable experience instead.

Also with Progressive Enhancement, it’s incredibly likely that your IE11 user, or your user on a low-powered device, or even your user on a poor connection won’t notice that they’re experiencing a “minor” experience because it’ll just work for them. This is the magic, right there. Everyone’s a winner.

Why Progressive Web Apps Are The Future of Mobile Web [2019 Research]

PWAs just work better than your typical mobile site. Period.

But bear in mind:

Maybe simply because the “A” in PWA stands for “app,” too much discussion around PWAs focuses on comparing and contrasting to native mobile applications. We believe this comparison (and the accompanying discussion) is misguided.

Less Data Doesn’t Mean a Lesser Experience| TimKadlec.com

If you treat data as a constraint in your design and development process, you’ll likely be able to brainstorm a large number of different ways to keep data usage to a minimum while still providing an excellent experience. Doing less doesn’t mean it has to feel broken.
