Latest changes and plans to this site

Jul 17, 2019

The website functions but the evolution will never stop.

I ran three tests (of two types) regarding the site:

  1. Official Lighthouse, results: 100 / 97 / 85 / 100
  2. Lighthouse , results: 67 / 97 / 93 / 100
  3. scanner, results: 66 hints

Obviously I’ll aim to achieve all 100 scores for Lighthouse and 0 hints for the scanner in the future. The following roadmap materialized in my mind:

  1. I’ll change the underlying framework. Although I upgraded to Bootstrap 4.3.1 + JQuery 3.3.1, the latter contains a medium security vulnerability. My website is static, so it’s not really an issue, but a newer / better framework could help with better scores, and those achievements should translate to real world enhancements. In the post a week ago I mentioned two material links and the ZURB Foundations. Turns out that some material themes are for React,which I won’t use (just like Vue or similar frameworks), since I try to be minimalistic and this is a static website after all. I’m pretty sure now that I’ll go with the Material Design Lite framework (MDL). The only feature I don’t see a clear equivalent in MDL is the carousel. I’ll either get rid of the carousel, develop my own based on the old 2018 summer version of (see GitHub issue), or somehow pull in the feature from mdl-ext.
  2. When changing frameworks I’ll try to work with the SCSS version, so I can get rid of any unused fluff at an early stage. Possibly same approach with the JavaScript assets, keeping them as minimal as possible.
  3. I’ll definitely need to do some image optimizations. That will possibly involve generating WebP images. Or some heavy optimization. Possibly generate mobile version of the large carousel images?
  4. I’ll remove unused CSS by an end of build by a gulp step or possibly with a Jekyll Ruby gem.
  5. As far as performance goes Bootstrap and MDL both use some fonts from For a quicker first paint event it’s advisable to use font-display CSS descriptor of the @font-face CSS rule. However these Google fonts are pulled in by a CSS @import directive and Google generates the font-face rules. Unfortunately, they don’t place any font-display descriptor there though, see more about this problem from CSS-Tricks. Right now I just scraped the CSS rules from the file served by Google, but that has some hashes so may not work forever (?). For a better solution I’ll try to use one of the service worker solutions, which are kinda hacky, but we’ll see.
  6. Finally I’m considering the use of a 3rd party blog post CMS / API service, like Siteleaf, but only if I find some satisfactory and free service. Note to self: see list at
