Oh sweet, I learned about a new CSS feature with good-enough support!
This lets you use CSS transitions for an element as it enters the page,
or becomes visible.
Firefox only has partial support for this feature rn, but its partial
support covers our case, I tested to make sure! (Specifically, it
doesn't handle transitioning from `display: none` yet, which isn't what
we're doing.)
No more of this loading everything into `application.css`! I'm
arbitrarily starting here because that's where I've been playing
lately, but this is part of a larger effort to move toward a more
straightforward CSS architecture (and away from Sass even?)
I skipped this for a bit because I couldn't think of a simple way to
adapt this behavior to a web component + vanilla CSS setting, but then
I thought of CSS variables, and sat down and cranked this out!
I noticed the last row of the species faces required a scroll, I forget
when that happened! But I made some tweaks, most notably widened the
container from the normal 800px, so that on bigger screens everything
lays out and aligns nice, without requiring any scrolling of the face
container!
Oh right, forgot about this lol!
The specific effect on Impress 2020 where the button label expands is,
kinda hard to implement in normal CSS/JS, and so I'm not in the mood
and I'm settling for the `title` attribute lol
Oh right, I need the error indicator to be part of a container that
also contains the outfit viewer, to appear below it!
I was motivated because I realized I forgot the Customize More button
so now I'm building it lol
The loading indicator *should* fade in after two seconds, to avoid a
flash of a loading indicator when the page loads quickly - but in some
circumstances it wouldn't delay:
1. Visit an item page. (It delays correctly the first time!)
2. Click "Infinite Closet", then click a link to another item page.
3. The loading indicator appears immediately, because this time the
web component JS is already loaded, so the `outfit-layer` elements
enter `:state(loading)` *immediately*. The element starts at
`opacity: 1`, and the delay doesn't matter, because it was never at
anything else.
In this change, we have the `outfit-viewer` web component take on a
`:state(after-first-frame)`, after a `setTimeout(0)` resolves. That
enables the loading state CSS to *never* apply on the first frame, but
then sometimes kick in on the *second* frame, so that the element is
correctly perceived as "transitioning" from hidden to visible, and the
two-second delay will apply.
Here, I remember the trick I learned when building the outfit viewer:
web components are great for making sure stuff stays initialized well
in a Turbo environment!
The problem was, after submitting the form and getting a new preview
loaded via Turbo, the part where we remove `inert` would get undone.
Additionally, this script only loads *once* per session, so if you
Turbo-nav to a different item then that part of the page never ran.
Instead, we use web components to remove the attributes on mount, then
again if they're ever reapplied by Idiomorph.
We mark the options as `inert` and `aria-hidden` while the JS is still
loading—and if the `noscript` tag tells us it's never coming, it covers
up the picker with a brief explainer!
The basics are working great! There's a few known missing things though:
- Add reasonable noscript behavior
- Disable options where there's no valid appearance
- Lay it out actually _good_, instead of just images dumped there
Adapting what the Impress 2020 UI does, but in Ruby instead!
I feel like this is case is really starting to show the power of doing
this stuff in Rails instead of via an API… we can *really* take
advantage of our models and our handy idioms at all points. This is
just so much less *code* than this feature takes in Node + GraphQL +
React.
Oh right, if the *label* is `:active`, that only applies if we're
clicking it with our mouse. But if the *toggle* is actively, that
applies both to mouse events on the label, and keyboard events on the
checkbox.
Specifically, if a movie layer was the top layer, the `cursor: wait` on
the preview wouldn't show, because the iframe's *contents* would take
priority, and they were using the default cursor.
This doesn't do a good job maintaining state across morphs, but hey
it's Working At All in terms of wiring, and that's good!!
Also need to style up the toggle as a cute button instead of a visible
checkbox and the words "Play/pause"!
Add some unobtrusive white background for contrast, show it when the
Turbo frame is loading too, add a spinner cursor, and fix a silliness
of how we put the `position: absolute` stuff into the component-y part
of the hanger spinner instead of this specific use case lol oops!
Oh right okay, attributes like `status="loading"` are more of an API
for the caller, whereas the internal state API is where you wanna put
things that are meant to be used in CSS selectors and stuff.
Instead of doing all this listening to Turbo events etc to know when
outfit layers might have changed, making it a custom element and wiring
in the behavior to its actual lifecycle makes it always Just Work!
The UI for it is just basic for my own testing rn: it sets the preview
background to gray while loading, then back to white when done!
This uses the new CSS `:has()` selector: we have JS manage the loading
state on each layer, then the container just restyles itself based on
whether any currently-loading layers are present.
This is a cute thing that I think sets us up for other stuff down the
line: move more of the outfit appearance logic into the `Outfit` class!
Now, we set up the item page with a temporary instance of `Outfit`,
then ask for its `visible_layers`.
Still missing restricted-zones logic and such, that's next!
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!
The table layout algo can get a bit funky about how it assigns extra
space, I want to encourage things like "Total: 5 items" etc not to
wrap, esp in the Dyeworks case where it's quite long!
There's more and more going on in here! Let's omit the base item name,
increase the table width a bit in this case, and tweak the rest a bit
while we're here.
I think it helps a bit to have only the label be dotted-underlined, to
hint that I'm offering help about what that *means*, but clear the way
for the value itself to be more visible and less cluttered.
I started writing this up, then sent a preview to a friend, and he was
like "oh cool, but also this is not correct?"
I didn't realize Dyeworks has limited-time support to be *able* to dye
certain items. Hey, glad we're writing this guide for people like me,
then! lol
I wonder if we can lean on Owls for this. It seems like they already
list "Permanent Dyeworks" for some items, I wonder if they say
something special for active limited-edition Dyeworks items!
A funny table-layout bug, where the item "Portal to the Unknown" had a
very long Owls listing ("Owls listing: Buyable - Magic Lens + Blank
Grey Tome (NP)"), and so the table layout tried to give it more room by
decreasing the width of the action cell and wrapping the "NC Trades"
action button text onto multiple lines.
The fix: don't allow that! The table layout will figure out how to
handle this being disallowed, and give the actions cell an appropriate
minimum width.
Note that there's a known performance issue here: we should try to
fetch all the OWLS values at once, instead of doing them in sequence
while rendering the page!
