In writing this, I tried to use The SEO Framework’s sitemap.xml, however, since the goal for this post was to try and do it in a way that was quick and easy to setup, I didn’t want to include a ton of extra dependencies (e.g. xml to json converters, sitemap generators, etc).
An idea I had was to add a pre-build script using wget to spider the entire site, ignoring robots.txt (i.e. -e robots=off), however, it was getting too convoluted for this post.
I like the idea of having a tool check your actual codebase (Purgecss) vs. the generated version of your website (UnCSS), as I do want all of my template code in my theme directory (not in the database). Of course, there are pitfalls, but if you didn’t need to theme any plugins, it’s gold.
