lighthouse VS Turbolinks

As you said, there are a few huge images that aren't optimized. You can use tools like Google Lightouse or Koalati to detect potential issues and find things that can be improved.

Lighthouse tests are a helpful method to measure your web vitals — you can run Lighthouse tests from Chrome DevTools, via the Lighthouse Chrome Extension, or in the command line:

Now let's check if we properly set up our PWA using a Google Lighthouse check. Right-click on your browser and select "inspect." On the inspect tabs, select lighthouse and click on generate report. If everything went well with your application, you should see an output like the one in the screenshot below:

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 particularly feasible if you want to make your content accessible to all.

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 is most likely to be impacted given the unpredictable speed of mobile data — all tests were conducted in an emulated mobile environment using a medium 3G network speed, on iPhone 6/7/8.

The next step would be to fine-tune our SEO scores for those pages, which can be done via Lighthouse.

It's on github

When the Turbolinks technology first came out in Rails 4, some people did not understand what it was really about. I happened to get it right away only because I personally implemented my own version of Turbo Drive for one of my client projects before Turbolinks was released (around 2012), so I really appreciated Turbolinks when it was released. With the latest updates in Rails 7, the Turbolinks technology has been renamed to Turbo Drive (now part of Hotwire) since it not only accelerates hyperlinks anymore, but also form submissions too.

Turbolinks, a great tool to make navigating your web application faster, is no longer under active development. It has been superseded by a new framework called Turbo, which is part of the Hotwire umbrella.

We’ll use Ruby on Rails and Turbo to accomplish this, but we could use Turbo’s predecessor, Turbolinks to achieve the same result, and Rails is only incidental to the finished project. We could just as easily use Turbo with any other "multi-page" framework and deliver the same experience.

Check out StimulusJs and Turbolinks their whole purpose is to add only a tiny bit of js to a server side rendered website, to give a feel similar to that of client-side rendered web pages.

Nice job solving this problem! This sounds similar to how Inertia works (https://inertiajs.com/how-it-works), or Turbolinks (https://github.com/turbolinks/turbolinks). You could dig through those libraries to see if / how they solved issues with global scope.
