JAMstack often promotes itself as an excellent way to provide performant sites. It's even the first listed benefit on jamstack.wtf, a "guide [which] gathers the concept of JAMstack in a straight-forward guide to encourage other developers to adopt the workflow". But too many JAMstack sites are very slow.
I really like that SpeedCurve tried to innovate with this recent "User Happiness" metric. It aggregates multiple technical metrics to decide if users visiting the page are happy or not with it. But I see several issues in this metric.
People tend to be lazy (I am often) and chose the easiest tool to do the job, even if it's not the best one. Medium is the new Blogger, but with a much nicer content editing UI, and a cleaner presentation of content to readers. People can create and account and start publish in a few minutes, it's really easy. But how can all this be free?
Enough. I'm fed up with Disqus. It's been useful, easy to plug on this blog, but it's a mess for web performance, and I don't own my data, so… bye bye. Webmention is now a great alternative, with more people implementing it, so let's try to keep only that.
I love when Web site/apps work even when I'm offline. I've made my SVG game esviji work offline thanks to appcache just after attending Jake Archibald conference about why Application Cache is a Douchebag during the 2012 edition of the Paris Web conference. Fortunately, we have now Service Workers (in some browsers), which gives us more control over this kind of cache for offline browsing. But as Uncle Ben says, “With Great Power Comes Great Responsibility”.
When trying to use a
100vhCSS value to build a new interface for a game that would use the full viewport, I discovered that this full height value meant the bottom of the game interface was partialy hidden behind the browser buttons bar or below the "fold" of some mobile browsers.
There have already been some explorations on responsive SVG images a while back, but when Joe Harrison posted a responsive icon concept on Dribbble and even a working version on a dedicated website, a few people thought this was so wrong they had to make their own version. I must admit I'm one of them… ;-)
