My blog goes stale until the second visit — how I fixed it with the correct cache strategy
An Astro service worker served every navigation from cache first, so new articles appeared one visit late. Listings now go to the network first.
Web Performance
Offline reading for the pages you visit on this Astro blog — a service worker, 50 pages capped, no TTL
How measurements decided a service worker for an Astro blog: 287KB precached instead of 11.7MB of HTML, 50 pages capped, and no expiry date.
A 2 MB PNG became 316 KB WebP — but only before the first commit
Measuring PNG, JPEG and WebP for article figures, why re-compressing the PNG made it larger, and why converting an image git already tracks reclaims nothing.
