In my last change, I didn't try to change the APIs too much, and kept the concept of `crossOrigin` running through `getBestImageUrlForLayer`.
Now, I've moved the `safeImageUrl` call _outside_ `getBestImageUrlForLayer`, by putting it at the call site: We now call `safeImageUrl` from `loadImage` (which needs to know the `crossOrigin` flag anyway!), and at the `img` tag call site.
This simplifies all of the call sites a lot, I think!
I've noticed that our Fastly proxy adds a surprising amount of latency on cache misses (500-1000ms). And, while our overall hit ratio of 80% is pretty good, most misses happen at inopportune times, like loading items from search.
But now that the Neopets CDN supports HTTPS, we can safely switch back to theirs for *most* image loads. (Some features, like downloads and movies, still require CORS headers, which our proxy is still reponsible for adding.)
This forgoes some minor performance wins (like the Download button now requires separate network requests), and some potential filesize reduction opportunities (like Fastly's auto-gzip which we're today using for SVGs, and eventually using their Image Optimizer for assets), to decrease latency. We could still potentially do something more powerful for low-power connections someday… but for now, with the cache miss latency being *so* heavy, this seems like the clear win for almost certainly *all* users today.
I have a hunch that people aren't finding the Download button! I'm not 100% sure what to do about that, but to start, I want right-clicking the image to give you a hint about it 😅
Woo, it's the big UI experiment! Let's see how it plays for folks 😅
Scrolling through a big lists page right now, I think this is a _huge_ improvement, I can get a sense of the lists and what's in them fast, and see matches fast, and dive quickly and with no extra load time when I want more. I'm pleased tbh!
Pulled MarkdownAndSafeHTML into a shared component, and use it on the single list page now too!
I also simplified some of the logic for the item list, because I figure we'll have to give the trade matching stuff its own pass, y'know?
Oops, I pulled `currentUserId` from the wrong place, so it was always acting as if you're logged in! Now, you can see the list page for your own private list!
I'm not sure real item data "should" ever do this? Our "Written Word Shower" had a blank description, but I think that was an error on our end.
Anyway, it's clearer than showing infinite loading, so!
Oops, okay, I guess I didn't test the new preview centering stuff with 1200x1200 images, like the Usul's Damask Markings.
Now, I apply a max size to the whole-ass container, and make the parent responsible for centering it.
So I finally started looking into the race condition that makes item previews sometimes fail to load, and as expected, it was that we were trying to load the movie before CreateJS had necessarily loaded. Usually the timing worked out, esp after a reload, but not under certain circumstances!
Anyway, I've been wanting for a while to just bundle them instead. That'll help us more eagerly load them when we need them, and not depend on external CDNs, and remove a bunch of loading state!
So yeah, I had to learn how the `easeljs` and `tweenjs` NPM packages did their bundling, and how to use `imports-loader` to let them just register straight onto `window`! But we got there and it's pretty nice tbh!
Woof, the "Swirl of Power Effect" item tanks my CPU waaay too much
(I bet it's those 7000x7000 PNGs lolol 😬)
Anyway, before thinking about optimizing specific issues, I'm just adding this emergency switch: if we detect FPS < 2 on any layer, we just pause the whole outfit, until the user decides to unpause.
Oh hey, turns out I was missing a step in movie clip stuff! Images aren't just for sprite sheets, but also sometimes they just want the raw images!
Here, we register them, uwu
Items like "Swirl of Power Effect" and probably others work correctly now!
That said, Swirl of Power takes WAY too much CPU lmao, I want to maybe add some kind of automatic kill switch lol
There are a couple spots where we parse SWF URLs to get the ID out! Most visibly, our Support tools were crashing on it. And internally, manifest loading wasn't working. (I'm not sure if this got caught or if it caused crashes in user space? I didn't see them when wearing a failing item)
Anyway, fixed now!
This is because it's the terminology I'm using elsewhere ("Items" and "Closet" are too overloaded in the UI), and because I want to start putting specific lists at like `/user/:userId/lists/:listId`!
I also create a redirect from the old URL, and also from the DTI Classic variant of the URL
Ah right, React state batching doesn't always work how I expect it to. The separate state caused the hook to return and cache `{loading: false, error: null, data: null}`, and then on a _later_ tick the data value showed up, but only _after_ the response was already cached!
This broken a bunch of species/color picker stuff, now it's fixed!
Okay, so getting the initial render down time for these faces is annoying, though I might come back to it…
But actually, the _worst_ part isn't the _initial_ render, which just kinda gets processed as part of the page navigation, right?
The _worst_ part is that we render it slowly _twice_: once on page load, as we send the `useAllValidPetPoses` fetch request; and then again when the fetch request ~instantly comes back from the network cache.
The fact that this requires a double-render, instead of just rendering with the cached valids data in the first place (like how our GraphQL client does), causes a second and highly-visible render of a slow-to-render UI!
So, here we update `useAllValidPetPoses` to cache its response in JS memory, similar in principle to how Apollo Client does. That way, we can return the valids instantly on the first render, if you already loaded them from the homepage or the wardrobe page or another item page!
This is a pretty easy change, that makes re-renders faster when something about the item preview state changes!
That said, the initial render is still pretty slow, too, and that's the one that's bothering me more lol
Ah oops, because I forgot to set `hiResMode` here in the image preloader, we would preload the PNG, and _then_ load the SVG separately.
This doubled the effective image loading time in Hi-Res Mode!
Now, the image preloader respects hi-res mode, and will preload the SVG in the SVG case, and the PNG in the PNG case.
If you're not in hi-res mode, then you don't care about broken SVGs, because you wouldn't have seen them anyway!
We also update the message to reference Hi-Res Mode.
We're just having too many glitchy SVGs for my taste, esp since TNT seems to just be using PNGs for now?
This change defaults us to using PNGs for users by default, with the option to use SVGs as a new "hi-res mode" setting.
This is our first ever setting, wow!
I'm also envisioning that like, if we get Fastly Image Optimizer set up, this could be a way to tune the quality of the incoming images.
We could also consider a setting to turn off animations altogether—like, just download the PNG instead of the movie, whereas right now we download the movie on the assumption that you might play it at any time.
The way we were checking for UC compatibility issues, was also triggering while the appearance was still loading, so items didn't have any appearance layers yet!
Now, we check for loading before testing for that glitch.
Oh right, adding user data to this query makes it uncacheable!
Split the query into the main public data, which will cache; and the user data, which will load in later.
I refactor the hide-badge thing into 3 "trade matching modes". Then, the logic for whether to hide specific badges moves into the component, and we use that same flag to decide whether to show the big word "match"!
Boom, cute owns/wants badges on "Latest items", and the item search page, and trade matches!
I'm gonna add some additional flair to the trade match case, too!
