I am finally done chasing a nearly perfect Google lighthouse score and have released Galaxie Blog version 1.35. I have a perfect score for 3 out of 4 categories, and the performance score generally falls between 70 and 90. Performance: 90%1 Accessibility: 100% Best Practices: 100%2 and SEO (Search Engine Optimization): 100%

Attaining this score was not easy- especially for a large blog site. This is major accomplishment.

I spent over a month working on all aspects of the site. The google audit checklist is exhaustive. For example, I am deferring all non essential resources until page load, lazy loading the images and media, using next generation image formats (webp)3 and networking protocols (http/2) if possible, have no errors written to the console, etc, etc.

I will write up several blog entries in the next couple of weeks to highlight some of my approaches.

1 Performance results can vary considerably.
2 Attained with the commercial Kendo license. The open source Kendo Best Practices score is at 86 due to the Kendo embedded jQuery library. According to Telerik, this should be fixed in the near future.
3 Webp images are only served when both the client and the server supports them. When webp is not supported, Galaxie Blog will fallback to traditional image protocols. I will write up an article on this in the near future.
