Astro Font Fallbacks with Capsize: reduce CLS
An alternative to Capsize for reducing font swap layout shift is Fontaine. It has a Vite plugin, and is able automatically to update font face CSS (like we will do, using Capsize metrics). We do something a little more manual here with Capsize, just to help get a grounding in the issue and solution approach.

You don't need zero JS website for a perfect Lighthouse score
Fonts are one of the biggest pain points in the context of performance optimization. I have decided to not use any CDN like Google Fonts but instead, I'm serving them myself. Also, I have used a cool package called Fontaine which reduces CLS by using local font fallbacks with crafted font metrics.

How I ruined my SEO
I started using fontaine on my blog. If you haven't tried it out, you can find it here. It helps reduce Cumulative Layout Shift. The flash of unstyled content jank that you can see when you first land on a site, before fonts have loaded. I can't see why that would be an issue. It should improve my blogs Core Web Vitals and help stuff rank better, not worse. I think this is a red herring.

Day.js is a lightweight alternative to the now deprecated date and time handling library, Moment.js. It is written in JavaScript and uses a similar API to Moment.js. Day.js is sufficient for date operations such as parsing, manipulation, and display. It is designed for use on both the browser and the Node.js runtime.

The Day.js Dilemma: How Should We Handle OSS Maintainers Going MIA?
As web developers, we heavily rely OSS packages. One popular example is Day.js, a JS lib for parsing, validating, manipulating, and formatting dates. It's a widely-used alternative to Moment, with over 17mil weekly downloads on npm.
A critical bug was discovered in Day.js (see: https://github.com/iamkun/dayjs/pull/2118) causing incorrect date manipulation (add, subtract) when in UTC TZ. This could have severe implications for any project relying on Day.js for date-related functionality. However, the maintainer of the project appears to be unresponsive, leaving the bug unresolved and the future of the library uncertain.
This raises some important questions for our community:
- At what point should we consider a widely-used OSS project "abandoned" if the maintainer is unresponsive?
- Is forking the project the best solution, or should we first try to reach out to the maintainer through other channels?
- Are there established community guidelines around responsiveness expectations for widely-used OSS projects?
- What are successful examples of community-driven forks or maintenance after a maintainer stepped away?
I am very aware that many of these developers give their spare time for free for these projects, with little or no payment, and I am very thankful for all their work. This developer does get some money (a small amount?) through OpenCollective, and possibly also works for a company (in China?) that makes a UI library, which I think uses Day.js internally.
