The longer I spend on an SPA, the more it feels like reimplementing the entire browser myself. Example: you set titles per-page. But then those titles persist when navigating to a different page. So you have to always set the page title on navigation, reimplementing the browser.
Likewise for the meta description tag: you have to actually find and modify the <meta name="description"> DOM node every time the user navigates to a new page. (And implementing the entire concept of "page" is your problem!)
As a result, we now have this component. Which I imagine is duplicated in tens or hundreds of thousands of other SPAs in the world, all reimplementing browser functionality.…
I think it's pretty clear where this goes in the long term, but I'm afraid to even write it out because I simultaneously (1) do not want to see it happen and (2) kind of want to be the one that does it.

"You have to do that on the server too!"

Please give me the benefit of the doubt: I have programmed computers.

If one server-side template renders a <title>, it does not affect every other server-side template that renders after it. That's what happens in an SPA.
Also got a bit of <massive tool that duct tapes dozens of projects together, each of which is a leaky abstraction, forming a larger and even more leaky meta-abstraction> solves this problem! I have gone down that road many, many times and it leads to:
These are pretty good summaries of how things go wrong in software!

1. Misunderstand the problem and claim that it doesn't exist or is trivial; or
2. Accept that the problem exists and blindly assume that installing a massive, opaque, frequently changing dependency "solves" it.
Things are *complicated*.
