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.
