Oops, my inbox was getting full of uncaught promise rejections of `loadImage`!
I'm pretty sure they're caused when multiple images in a movie fail to load (e.g. network problems), but we fail to cancel them. So, the first failure would be caught as a part of `Promise.all` in `loadMovieLibrary`, but then subsequent failures wouldn't be caught by anything, and would propagate up to the console and to Sentry as uncaught errors.
In this change, we make a number of improvements to cancellation. The most relevant change for this bug is that `loadMovieLibrary` will now automatically cancel all resource promises when it throws an error! But this improved robustness also enabled us to finally offer a simple `cancel()` method on movie library promises, which we now available ourselves of at call sites, too.
I'm seeing uncaught promise rejections in `loadImage`? It's hard to know exactly where it's actually coming from, those _should_ be caught?
My guess is that it's coming from canceled images, which are throwing errors even after loading? I don't totally understand how, because looking back, I don't think the `cancel` method was actually called???
Anyway, I fixed it so cancel actually _is_ called, and that we don't throw errors when the canceled image _correctly_ fails to load.
This should be more robust either way, but hopefully it also stops the flow of errors?
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.
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
Oops, previously the MajorErrorMessage was willing to shrink the width of the cute Grundo Programmer icon, to allow error messages with long words to avoid word breaks.
Here, we switch `1fr` for `minmax(0, 1fr)`, which allows the text zone to get smaller. (`1fr` is short for `minmax(auto, 1fr)`, which isn't capable of shrinking smaller than the natural value.)
Now, the error text is more willing to shrink by word-wrapping, than the image is by shrinking the image. Success!
Boom, pulled some stuff out into util! Now we also have error boundaries in both panels of the wardrobe page.
You can test this one by visiting `/outfits/new?send-test-error-for-sentry`, just like on the home page! Util component for fake errors owo
Oops, the sequence here was:
1) Save a new outfit
2) The debounced outfit state still contains id=null, which doesn't match the saved outfit, which triggers an auto-save
3) And now again, the debounced outfit state contains the _previous_ saved outfit ID, but the saved outfit has a _new_ ID, so we save the _previous_ outfit again
and back and forth forever.
Right, ok, simple change: if the saved outfit ID changes, reset the debounced state immediately, so it can't even be out of sync in the first place! (I also considered checking it in the condition, but I didn't really understand what the timing properties of being out of sync due to debouncing would be, and it seemed to not represent the reality I want.)
I think this will be generally useful to minimize switching around for common operations, but also I'm thinking of building a bulk assign tool for things with broken body IDs, and this will be the place for it to live, I think
Oops, I got distracted partway through typing the domain, lol! They point to a real place now, lol! (not a very helpful place, but at least the real one I intended! :p)
When I added this new error case in the last change, I made it log to Sentry, because I don't think this should be possible under our data set, so if it happens I want to hear about it. Same is true for this error case, so let's log it too!
A crasher, fixed! :) I made Jetsam Lunch Lady Gloves no longer crash the page, lol - its thumbnail URL is "/items/clo_jetsam_lunchladygloves.gif", with no host specified. The shoes are the same!
I also added a fallback, to return a placeholder error URL instead of just letting the URL through as-is—and I updated the other error case to behave the same. I'd rather have a specific isolated feature get crashy, than have the mixed content warning pop up, or let through some mystery unparseable URL that, idk, might be part of an attack?? Seems better to fail hard-but-small than easy-but-potentially-leakily.
I've been getting more Sentry errors about JS chunk errors after deploys, and finally looked into it!
Turns out that, our try/catch handling was working great, and the page was reloading correctly for users as expected. But in these scenarios we would _also_ throw and log two uncaught errors!
The first is that, because we're a single-page app, unrecognized routes fall back to the index.html by default (to power our custom client-side routes, like /outfits/123 etc). So this meant that missing JS files, which _should_ be returning a 404, were instead returning 200 OK and an HTML file, which failed to parse. (And running the script isn't included in the catchable part of the `import` promise!)
Now, in our `vercel.json` config, we catch those paths specifically and 404 them. (The exact choice of path is important: on dev, all these routes run _before_ the dev server, which is responsible for serving the static files - but dev doesn't include hashes in the JS file names, so this 404 route only matches built prod JS files, not local dev JS files.)
The second is that we failed to return anything to `@loadable/component` in the error case, so it would try to render `undefined` as if it were a component class. Now, we return a trivial component class that returns null!
Sooo, I added this more graceful regex and error logging… then realized that this shouldn't be happening in the first place, because we should only be removing the last word of the query if you picked the filter via typing, not advanced search!
I'm glad to have the assertion error and the new handler, but I'll fix the cause too in the next change :p
1. Search for something
2. Clear the search bar
3. Quickly start typing something new
Before this change, the results would clear on #2, but then the old results would show up again during #3, before the loading state for the new query.
This matches the logic, right? We hid the results when both the current and debounced query were empty, and, during that time, neither is empty.
Instead, here we update the `useDebounce` hook to have a `forceReset` option, to immediately clear out the value instead of waiting.
Woo, it's looking pretty good, I think!
I didn't bother with pagination yet, since I feel like that'll be a bit of a design and eng lift unto itself... but I figured people would appreciate the ability to look up individual items, even if the rest isn't ready yet 😅
Two fixes in here, for when image downloads fail!
1) Actually catch the error, and show UI feedback
2) Throw it as an actual exception, so the console message will have a stack trace
Additionally, debugging this was a bit trickier than normal, because I didn't fully understand that the image `onerror` argument is an error _event_, not an Error object. So, Sentry captured the uncaught promise rejection, but it didn't have trace information, because it wasn't an Error. Whereas now, if I forget to catch `loadImage` calls in the future, we'll get a real trace! both in the console for debugging, and in Sentry if it makes it to prod :)
This has been bothering me for a long time, but I couldn't really figure out what to do about it. But tweaking the site bg color a smidge has helped us really add texture to the cards I want to have pop out, like the outfit polaroids!
I kinda went all-in in a burst, but tbh I think it looks great :3
I haven't really touched the wardrobe page with it yet though, that'll probably need some tweaking... for now I'm overriding it to keep the old background!
When you navigated directly to ItemPage, the new `safeImageUrl` function would crash during the loading state, because it was trying to safe-ify `undefined`.
Now, I've just made `safeImageUrl` more resilient to that particular kind of unexpected input, by passing through null-y values without change.
When we decided to start out with /api/assetProxy, we didn't know how much the load would be in practice, so we just went ahead and tried it! Turns out, it was too high, and Vercel shut down our deployment 😅
Now, we've off-loaded this to a Fastly CDN proxy, which should run even faster and more efficiently, without adding pressure to Vercel servers and pushing our usage numbers! And I suspect we're gonna stay comfortably in Fastly's free tier :) but we'll see!
(Though, as always, if Neopets can finally upgrade their own stuff to HTTPS, we'll get to tear down this whole proxy altogether!)
So I broke the Download button when we switched to impress-2020.openneo.net, and I forgot to update the Amazon S3 config.
But in addition to that, I'm making some code changes here, to make downloads faster: we now use exactly the same URL and crossOrigin configuration between the <img> tag on the page, and the image that the Download button requests, which ensures that it can use the cached copy instead of loading new stuff. (There were two main cases: 1. it always loaded the PNGs instead of the SVG, which doesn't matter for quality if we're rendering a 600x600 bitmap anyway, but is good caching, and 2. send `crossOrigin` on the <img> tag, which isn't necessary there, but is necessary for Download, and having them match means we can use the cached copy.)
Still just read-only stuff, but now you can look at all the different poses we have for a species/color!
Soon I'll make the pose/glitched stuff editable :3
Some sizable refactors here to add the ability to specify appearance ID as well as pose… most of the app still doesn't use it, it's mostly just lil extra logic to make it win if it's available!
(The rationale for making it an override, rather than always tracking appearance ID, is that it gets really inconvenient in practice to //wait// on looking up the appearance ID in order to start loading various queries. Species/color/pose is a more intuitive key, and works better and faster when the canonical appearance is what you want!)
Hey wow this was not so hard, just set some global styles, removed some hardcoded colors, and walked through the remaining hardcoded colors to pick a dark mode variant :) neat!!
