Blowfish

A reader clicking from my homepage to a post with a diagram got a block of raw mermaid source. The same reader pasting that post's URL directly got a rendered diagram. Same page, same build, same browser. The difference was the click, and the bug had been live on this site for months across every diagram, every math formula, and every chart, because I had only ever tested pages by loading them directly. 🧪 Tested with Blowfish 2.10x · htmx 2.0.10 Two features, both reasonable, one collision # This site has htmx’s hx-boost on the body: internal navigation swaps page content in place instead of doing full page loads, which keeps transitions smooth. Separately, the Blowfish theme is smart about heavy libraries: mermaid, KaTeX, and Chart.js bundles are only included on pages that use them, injected into the <head> of exactly those pages.

For six months I assumed nobody could tell whether anyone read this blog, because I had never added analytics. Wiring up Cloudflare Web Analytics by hand taught me two things: the obvious place to paste the snippet would have shipped my Playwright suite's page views into the dashboard, and the dashboard had been quietly counting my visitors for two months anyway. 🧪 Tested with Hugo 0.163.3 · Blowfish 2.104 Publishing into the void # The site’s hugo.toml had a googleAnalytics line commented out since roughly the first commit. I never uncommented it. GA4 wants a cookie disclosure, ships a chunky client, and ad blockers eat it anyway, which felt like a lot of ceremony for a personal blog whose one open question was “does anybody visit.”

Blowfish

My diagrams rendered on refresh and vanished on click. The head never loaded.

Blowfish supports four analytics providers. Cloudflare Web Analytics isn't one.
