I was once tasked with migrating a landing page with an associated blog from CSR to use SSG. Once I had done so, however, I noticed that my Lighthouse score had gone down despite my page rendering a much more useful initial page significantly faster than it’d taken for my app’s spinner to go away.

The website should score 80+ in performance, SEO, and accessibility in Google Lighthouse tests. Plus, the load time should always be less than 2 seconds and ideally in the order of a few hundreds of milliseconds. The real challenge lies here, since the website consists of more than 2 million pages, and pre-rendering them all will take weeks. Also, the content shown in most of the pages is not static. Thus, we…

Luckily, writing accessible code is often the same thing as writing simple, effective front-end code. Browsers are intended for general use and offer a lot of functionality intended to make sure that it’s possible for developers to write accessible code. For instance, this is what the Lighthouse tab in Chrome does. Translating stored information into a visual medium that a non-technical user can manipulate is kind…

Lighthouse [1][2] Accessibility audit/ scores can be a good tool to check A11Y issues automatically, and it is fairly easy to integrate into your CI/CD Pipelines to get the report automatically to check for issues/ regression. The web accessibility world is complex enough that simulating different methods of access like using screen readers or different font-sizes and doing manual tests for compliance is not…

Performance was compared between the Next.js site and Eleventy site using three free tools: Google Lighthouse, web.dev/measure and Web Page Test. Lighthouse tests were run in Brave Browser dev tools, Web Page Test runs were conducted via the web app using the London, UK – EC2 server, and web.dev tests were conducted in the browser. Given that I advocate for mobile-first development — and that’s where performance…

Hopefully that helps, but let me know if you meant something else!
