Note

If building the site with this branch after using npm run dev-site-with-docker, generated files in docs/_site/ may belong to root. To fix this:

sudo rm -rf ./docs/_site/

Benefits

• drop ruby dependency

Changes

Eleventy is mostly compatible with Jekyll, so there are minimal changes to the site.

The main changes are:

• collections need to be defined explicitly, and (may) need to change dir
• collections are referenced via collections.x instead of site.x
• collection props are referenced via item.data.x instead of item.x
• page props are renamed from e.g. page.title to global title
• include vs page usage of the posts collection means that post now becomes post.data vs global, depending on how the template is used

Hello @alxndrsn, I gave this a spin and this looks like a great start! Thanks very much.

I have some capacity to continue the work, would you mind if I move this branch into the PouchDB repo and finish it?
