I’m in the process of converting a Wordpress blog to a static site. We did have significant comment traffic back in the day so I did look into how to maintain comment functionality. I found Comentario https://docs.comentario.app/en/ which is a standalone comments engine that can be self-hosted and linked to the blog page. Single stand alone Go executable, SQLite database - seems dead simple and has built-in ways to migrate Wordpress comments.
Still, since we do not get that many comments these days, I’ll probably postpone it and just provide a static render of existing / historical comments which does have value for archival and discussion purposes.
It dumps all pages and articles as markdown with most Wordpress metadata as front matter metadata, and all comments in a separate yaml file which can be processed as needed. It creates a minimal theme with the necessary templates to do a basic static render of the content. It does need some theme and template tweaking to match Wordpress url structure and ensure all pages end up in the same url/permalink.
I also used a Wordpress hugo exporter plug-in about 3 years ago - worked mostly the same.
Using Hugo still allows me to more easily add content to the site while maintaining a consistent templating and design.
I also experimented with doing a simple static dump of html as generated by Wordpress - I tried two ways, using wget —-mirror which kinda worked but generated a lot of redundant pages, and a Wordpress plugin called “simply static” which was supposed to do something similar but in the end didn’t work.
In the end I decided against the static dump because it would have entirely “frozen” the site in time - I did want the ability to add content down the line; or change the design without having to modify the content significantly. Archiving sites verbatim is best left to the experts at archive.org :)
