Because I've run out of time I've only got this short and rough post about Structuring Lapis Projects. It's meant to help give perspective on the right way to keep your code organized.
I don't know that anyone else experienced this, but when I first encountered Lapis the setup process definitely took longer that it might have. Thus I've written Preparing for Lapis: OpenResty, LuaRocks, PostgreSQL, Tup, Sass.
