Jekyll blog show posts under a category

Question

Answer 1

I can of course create a directory dedicated to each category and then make index.html inside it, but there must be a better way.

This is a great way to do it, isn't much work at all and works flawlessly on gh-pages. It's exactly what I do on my own sites as I prefer to keep my .md posts filed by category in the directory structure, so I simply have:

/blog/
    /_posts/20015-01-01-my-awesome-post.md
    index.html

/labs/
    /_posts/20015-01-01-my-technical-post.md
    index.html

I find it preferable for maintenance to not have 1001 posts all in _posts/ and I get the pretty permalink structure I want without entering categories in each posts front-matter.
