It's only actually used in two JS files, so rather than doing a weird
global `$.ajaxSetup` call, let's just inline it into the small handful
of AJAX calls that actually care.
I haven't been running Prettier consistently on things in this project.
Now, it's quick-runnable, and I've got it on everything!
Also, I just think tabs are the right default for this kind of thing,
and I'm glad to get to switch over to it! (In `package.json`.)
First one, Turbo reasonably yelled at us in the JS console that we
should put its script tag in the `head` rather than the `body`, because
it re-executes scripts in the `body` and we don't want to spin up Turbo
multiple times!
I also removed some scripts that aren't relevant anymore, fixed a bug
in `outfits/new.js` where failing to load a donation pet would cause
the preview thing to not work when you type (I think this might've
already been an issue?), reworked `item_header.js` to just run once in
the `head`, and split scripts into `:javascripts` (run once in `head`)
vs `:javascripts_body` (run every page load in `body`).
I changed the type of this tag without realizing the JS references it
by both class and `div`!
I think at the time this was a perf suggestion for jQuery, because the
best way to query by class name was to query by tag first then filter?
It's possible our jQuery still does this, but I don't imagine it's very
relevant today, so I'll just remove that for better guarding against
similar bugs in the future instead.
Okay, so I still don't know why rendering is just so slow (though
migrating away from item translations did help!), but I can at least
cache entire closet lists as a basic measure.
That way, the first user to see the latest version of a closet list
will still need just as much time to load it… but *only* the ones that
have changed since last time (rather than always the full page), and
then subsequent users get to reuse it too!
Should help a lot for high-traffic lists, which incidentally are likely
to be the big ones belonging to highly active traders!
One big change we needed to make was to extract the `user-owns` and
`user-wants` classes (which we use for trade matches for *the user
viewing the list right now*) out of the cached HTML, and apply them
after with Javascript instead. I always dislike moving stuff to JS, but
the wins here seem. truly very very good, all things considered!
From an era when we didn't have that! Now we do!
(My motivation is that I'm trying to add new JS to this page and errors
in stickUp are crashing the page early, womp womp!)
We lose no-JS support, which I kinda miss, but caching is gonna be more
important down the line. Delete form moves next, then we cache.
CSRF token changes: it looks like, by setting a data attribute in AJAX, I
was overwriting the CSRF token. I don't remember it working that way, but
now we use beforeSend to add the X-CSRF-Token header instead, which is nicer,
anyway. The issue might've been something else, but this worked :/
The CSS was also not showing the loading ellipsis properly. I think that's a
dev-only issue in how live assets are being served versus static assets, but
may as well add UTF-8 charset directives everywhere, anyway.
