A great primer on using srcset and picture. I think I’ll be referring back to this a lot.
One of the other arguments we hear in support of the SPA is the reduction in cost of cyber infrastructure. As if pushing that hosting burden onto the client (without their consent, for the most part, but that’s another topic) is somehow saving us on our cloud bills. But that’s ridiculous.
Aaron outlines some sensible strategies for serving up images, including using the Cache API from your service worker script.
Aaron gives a timely run-down of all the parts of a web experience that are out of our control. But don’t despair…
Recognizing all of the ways our carefully-crafted experiences can be rendered unusable can be more than a little disheartening. No one likes to spend their time thinking about failure. So don’t. Don’t focus on all of the bad things you can’t control. Focus on what you can control.
Start simply. Code defensively. User-test the heck out of it. Recognize the chaos. Embrace it. And build resilient web experiences that will work no matter what the internet throws at them.
It must be the day for documenting the history of CSS. Here’s an article by Aaron on the extraordinary success story of CSS Grid. A lot of the credit for that quite rightly goes to Rachel and Jen:
Starting with Rachel Andrew coming in and creating a ton of demos and excitement around CSS Grid with Grid by Example and starting to really champion it and show it to web developers and what it was capable of and the problems that it solves.
Then, a little bit later, Jen Simmons created something called Labs where she put a lot of demos that she created for CSS Grid up on the web and, again, continued that momentum and that wave of enthusiasm for CSS Grid with web developers in the community.
A fantastic piece by Aaron who—once again—articulates what I’ve been thinking:
Your site—every site—should be a PWA.
He clearly explains the building blocks of progressive web apps—HTTPS, a manifest file, and a service worker—before describing different scenarios for different kinds of sites:
Progressive Web Apps may seem overly technical or beyond the needs of your project, but they’re really not. They’re just a shorthand for quality web experiences—experiences that can absolutely make a difference in our users’ lives.
Highly recommended!
