Coroutines and web components (via) I like using generators in Python but I rarely knowingly use them in JavaScript—I’m probably most exposed to them by Observable, which uses then extensively under the hood as a mostly hidden implementation detail.

Laurent Renard here shows some absolutely ingenious tricks with them as a way of building stateful Web Components. # 9th March 2024, 3:38 am

Observable Framework 1.1 (via) Less than three weeks after 1.0, the 1.1 release adds a whole lot of interesting new stuff. The signature feature is self-hosted npm imports: Framework 1.0 linked out to CDN hosted copies of libraries, but 1.1 fetches copies locally and then bundles that code with the deployed static site.

This works by using the acorn JavaScript parsing library to statically analyze the code and find all of the relevant imports. # 5th March 2024, 9:12 pm
