In my day job, I work on a JavaScript framework (LWC). And although I’ve been working on it for almost three years, I still feel like a dilettante. When I read about what’s going on in the larger framework world, I often feel overwhelmed by all the things I don’t know. One of the best ways to learn how something works, though, is to build it yourself. And plus, we gotta keep those “days since last

Dave Rupert recently made a bit of a stir with his post “If Web Components are so great, why am I not using them?”. I’ve been working with web components for a few years now, so I thought I’d weigh in on this. At the risk of giving the most senior-engineer-y “It depends” answer ever: I think web components have strengths and weaknesses, and you have to understand the tradeoffs before deciding when

28 Nov Shadow DOM and accessibility: the trouble with ARIA Posted November 28, 2022 by Nolan Lawson in accessibility, web components. Tagged: shadow dom. 3 Comments Shadow DOM is a kind of retcon for the web. As I’ve written in the past, shadow DOM upends a lot of developer expectations and invalidates many tried-and-true techniques that worked fine in the pre-shadow DOM world. One potentially sur

A few months ago, I gave a talk on CSS performance at performance.now in Amsterdam. The recording is available online: (You can also read the slides.) This is one of my favorite talks I’ve ever given. It was the product of months (honestly, years) of research, prompted by a couple questions: What is the fastest way to implement scoped styles? (Surprisingly few people seem to ask this question.) Do

Five years ago, I started a journey to build a better Mastodon client – one focused on performance and simplicity. And I did! Pinafore is the main Mastodon client I’ve used myself since I first released it. After five years, though, my relationship with social media has changed, and it’s time for me to put Pinafore out to pasture. The pinafore.social website will still work, but I’ve marked the re

27 Jun SPAs: theory versus practice Posted June 27, 2022 by Nolan Lawson in performance, Web. Tagged: spas. 17 Comments I’ve been thinking a lot recently about Single-Page Apps (SPAs) and Multi-Page Apps (MPAs). I’ve been thinking about how MPAs have improved over the years, and where SPAs still have an edge. I’ve been thinking about how complexity creeps into software, and why a developer may cho

21 May The balance has shifted away from SPAs Posted May 21, 2022 by Nolan Lawson in Web. Tagged: spas. 24 Comments There’s a feeling in the air. A zeitgeist. SPAs are no longer the cool kids they once were 10 years ago. Hip new frameworks like Astro, Qwik, and Elder.js are touting their MPA capabilities with “0kB JavaScript by default.” Blog posts are making the rounds listing all the challenges

The tooling exists, but it’s complicated, cumbersome, and often doesn’t answer the simple question: Why is my app leaking memory? Because of this, I’d wager that most web developers a
