Just stripping out the big React component, and having Rails output it!
There's a lot of work rn in extracting the Impress 2020 dependency from
the `wardrobe-2020` React app, and I'm just curious to see if we can
simplify it at all by pulling this stuff *way* back to basics, and
deleting the item page part of `wardrobe-2020` altogether.
In this draft, we regress a lot of functionality: it just shows the
item on a Blue Acara, with no ability to change it! I'm gonna play with
putting more of that back in.
I also haven't actually removed any of the item page React code; I just
stopped calling it. That can be a cleanup for another time, once we're
confident in this experiment!
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 *think* what I'm observing is that:
1. The zone restrictions are different between these items.
2. The zone restrictions *change* when reloading the page sometimes. (I
assume from remodeling?)
3. The items look very buggy on many pets, because many appearances
seem to expect different zone restrictions than the item actually
has.
I think what this means is:
1. TNT has finally unbound restricted zones from the item level, and
allowed different appearances to have different restrictions. Neat!
2. The API still serves it the same way, as a field on the item.
So I think this means we need to update our schema to reflect the fact
that an item's `zones_restrict` field isn't *really* a property of the
item; it's a property of the combination of the item and the current
body ID.
My gut take here is that maybe this means it's time for the Large
Refactor that I've kinda been interested in for a while, but been
avoiding because of Impress 2020 compatibility issues: instead of a
`body_id` field on assets, and having them directly belong to items,
make an `ItemAppearance` record (closer to how 2020's GQL API modeled
it, I was looking ahead to this possibility!) that's keyed on item and
body ID, and assets belong to *that*.
Then, we could move the zones restriction field onto the
`ItemAppearance` record instead. And then it doesn't really matter to
us how TNT models it internally; whatever we saw is what we use.
(Again, I looked ahead to this in the 2020 app, and tried to use the
`restrictedZones` field on `ItemAppearance` when possible—even though
it secretly just reads directly from the `Item`!)
…but that's a pretty big departure from how things are modeled now, and
isn't something we can just throw together—especially coordinating it
across both apps. I was getting close to being able to shut off 2020
from a *front-facing* perspective (but still keeping a lot of the GQL
endpoints open for the wardrobe-2020 frontend), but I don't think we're
very close to being able to try to target turning off 2020's *backend*
as a prereq to this; or at least, if we do, we should expect that to
take a while. (Counting now, there's still 9 GQL queries—not as many as
I expected tbh, but still quite a few.)
So idk how to sequence this! But for now, let's put out a warning, and
start setting expectations.
It was a bit tricky to figure out the right API for this, since I'm
looking ahead to the possibility of splitting these across multiple
pages with more detail, like we do in DTI 2020.
What I like about this API is that the caller gets to apply, or not
apply, whatever scopes they want to the underlying hanger set (like
`includes` or `order`), without violating the usual syntax by e.g.
passing it as a parameter to a method.
I guess I deleted this a while ago without really noticing… I think I'd
at some point like to replace this with like, the DTI 2020 improved
table layout thing, but I figured this would be pretty quick to throw
in and make the page not feel like a pain to use lmao
Oh yeah, a long-standing limitation. Good thing we're better at stuff
now!
This is also probably the real cause of the weird number of slight
discrepancies between main DTI and DTI 2020 when I eyeballed stuff lol
oh, well, that and the missing default-lists. A bit messy!
There was a time when I used an old proxy server to try to fix mixed
content issues, and I eventually removed it but never took the tendrils
out from the code.
We probably _should_ figure out how to secure these URLs! But until
then, we may as well simplify the code.
Eyyy tasty! There were some issues with conflicting styles with the main app, but I think we got it!
Scoping Chakra's CSS reset was a big deal to not accidentally overwrite the app's own styles lol, and we had to solve a specificity problem for that, thanks Aria for the :where tip!! <3
Idk this one might actually be a bit of a pain to load? But I'd want to optimize it differently anyway, and there's overhauls we're already planning to do here.
Just removing some caching and the expiration of it! There's still more superfluous(?) caching on the item page to audit, but these seem a bit more sensible about avoiding loading extra data.
Most of the reasoning is documented in the big comment. In short, we tried
to solve the problem with caching, but the caching should hardly be necessary
now that the bottleneck should be fixed. We'll see on production if it
actually solves the whole problem, but I've confirmed in the console that
redefining this function makes random_basic_per_species (as called during
rendering) a ton faster. And this way we keep our randomness, woo!
items#show has been very slow recently, and I think it's because there's a lot
of querying to be done. Another option would have been to attempt to
short-circuit Item#supported_species if not body specific, but that would
still leave us with 1s load times for body specific items, which is not
satisfactory. The short-circuiting might still be worth doing, but probably
not now.
I'm also not sure that this is actually the core performance problem, but
we'll see. It definitely helped on the dev server: items#show took about
200ms on item pages where everything but species images were cached, then
took about 30ms on subsequent loads. Looking like a good candidate.
