Cloudinary Fetch with Eleventy (Respecting Local Development)

4.12.2020
This is about a wildly specific combination of technologies — Eleventy, the static site generator, with pages with images on them that you ultimately want hosted by Cloudinary — but I just wanna document it as it sounds like a decent amount of people run into this situation.

AVIF has landed

8.9.2020
Everybody is talking about AVIF today because of Jake’s blog post. As the say, I was today years old when I learned AVIF was a thing. But thanks to web technology being ahead of the game for once, we can already take advantage of it. This will be easier if you’ve abstracted your...
