Add ETag header for static responses. I’ve been procrastinating on adding better caching headers for static assets (JavaScript and CSS) served by Datasette for several years, because I’ve been wanting to implement the perfect solution that sets far-future cache headers on every asset and ensures the URLs change when they are updated.
Agustin Bacigalup just submitted the best kind of pull request: he observed that adding ETag support for static assets would side-step the complexity while adding much of the benefit, and implemented it along with tests.
It’s a substantial performance improvement for any Datasette instance with a number of JavaScript plugins... like the ones we are building on Datasette Cloud. I’m just annoyed we didn’t ship something like this sooner! # 17th March 2024, 7:25 pm
Speedometer 3.0: The Best Way Yet to Measure Browser Performance. The new browser performance testing suite, released as a collaboration between Blink, Gecko, and WebKit. It’s fun to run this in your browser and watch it rattle through 580 tests written using a wide variety of modern JavaScript frameworks and visualization libraries. # 12th March 2024, 4:26 am
JavaScript Bloat in 2024 (via) Depressing review of the state of page bloat in 2024 by Nikita Prokopov. Some of these are pretty shocking: 12MB for a Booking.com search, 9MB for a Google search, 20MB for Gmail(!), 31MB for LinkedIn. No wonder the modern web can feel sludgy even on my M2 MacBook Pro. # 22nd February 2024, 11:31 pm
