Alex Russell on browsers, standards, and the process of progress. Update: After further investigation, an even better solution has presented itself, which is documented in the next post. The new content-visibility CSS property finally allows browsers to intelligently decide to defer layout and rendering work for content that isn't on-screen. For pages with large DOMs, this can be transformative. I

Alex Russell on browsers, standards, and the process of progress. TL;DR* we cannot continue to use as much JavaScript as is now normal and expect the web to flourish. At the same time, most developers experience no constraint on their use of JS...until it's too late. Lightweight, effective tools are here, but we're stuck in a rhetorical rut. We need to reset our conversation about "developer exper

Alex Russell on browsers, standards, and the process of progress. TL;DR: performance budgets are an essential but under-appreciated part of product success and team health. Most partners we work with are not aware of the real-world operating environment and make inappropriate technology choices as a result. We set a budget in time of <= 5 seconds first-load Time-to-Interactive and <= 2s for subseq

Alex Russell on browsers, standards, and the process of progress. Mikeal Rogers reached out last week to talk about Web Components, which surprised me, but his follow-up blog post is essential, timely reading. Dimitri Glazkov, Alex Komoroske, and I started the project that designed and (for many years) iterated on Web Components with a few primary goals in mind: Enhance component portability Shrin

Alex Russell on browsers, standards, and the process of progress. Since Frances and I published a blog post last year introducing Progressive Web Apps, a healthy conversation has started about what is and isn't a PWA. There are a lot of opinions and many shades of gray. What are the hard requirements? Which requirements are marginal? What's aspirational? This article outlines these requirements, a

Alex Russell on browsers, standards, and the process of progress. A lot of smart folks keep asking me why AppCache isn't a good enough solution for "offline" and why it was necessary to invent Service Workers. It's a great question! Motivated by the regrettably uneven browser support landscape for Service Workers, there's a real incentive to "just make something work offline" on iOS or old-IE. Thi

Alex Russell on browsers, standards, and the process of progress. It happens on the web from time to time that powerful technologies come to exist without the benefit of marketing departments or slick packaging. They linger and grow at the peripheries, becoming old-hat to a tiny group while remaining nearly invisible to everyone else. Until someone names them. This may be the inevitable consequenc

Alex Russell on browsers, standards, and the process of progress. One strain of objection I often hear about the project of making the web more extensible is that it implies travelling further down the JavaScript rabbit hole. The arguments often include: No other successful platform is so limited to a single language (in semantics if not syntax). Better languages exist and, surely, could be hooked

Alex Russell on browsers, standards, and the process of progress. One of the things I've poured myself into this year -- with a merry band of contributors including Domenic Denicola, Anne van Kesteren, Jake Archibald, Mark Miller, Erik Arvidsson, and many others -- has been a design for Promises that DOM and JS can both adopt. There's a (very) long history of Promises, Deferreds, and various other

Alex Russell on browsers, standards, and the process of progress. By now you've seen the news about Blink on HN or Techmeme or wherever. At this moment, every pundit and sage is attempting to write their angle into the annoucement and tell you "what it means". The worst of these will try to link-bait some "hot" business or tech phrase into the title. True hacks will weave a Google X and Glass refe

Alex Russell on browsers, standards, and the process of progress. Jetlag has me in its throes which is as good an excuse as any to share what has been keeping me up many nights over the past couple of years; a theory of the web as a platform. I had a chance last week to share some of my thinking here to an unlikely audience at EclipseCon, a wonderful experience for which my thanks go to Mike Milin
