I started running goaccess on the reverse proxy in front of computer.rip and some other sites just a few weeks ago... it has answered basically every question I've wanted from simple website analytics and it was very fast to set up and very response. Just a great tool all around.

Thank you for sharing this.

Well that's your own fault for using inferior technologies.

Don't use SPAs, switch back to traditional server side rendering.

I wonder if you could use CSS media queries to collect additional data about device characteristics, by linking to different URLs at different breakpoints?

Like a breakpoint for portrait mode would set the background of something to an image that's just a 1x1 pixel. So when that resource is accessed, you know the request came from a device in portrait.

I guess it depends on how different browsers decide to access resource urls in CSS files. If a browser just downloads everything first, and then processes the media queries, then it wouldn't work.

You get most of the value from the UA from just seeing if someone is on a mobile phone or desktop device. That is easy to parse.

Most of the other metrics are noise and don't impact business decisions.
