Oops, right, I meant to use the new `impress-outfit-images.openneo.net` host for this! It works just fine from `impress-2020.openneo.net` as the backing source right now, but I want these semi-permanent URLs to be a bit more decoupled.
This is mostly for decoupling's sake: I want pretty outfit URLs that aren't dependent on the `/api/outfitImage` path structure, so that we can serve them as ~permanent pretty URLs that don't actually indicate where or how the image is stored.
This reverts commit a0121f09ea.
I didn't realize that VERCEL_URL wouldn't use the canonical URL. And thinking further about the Open Graph semantics, I think having just one canonical host makes more sense, even if it makes testing a bit more annoying in some cases.
Hmm, the built copy of the HTML isn't deployed with the API function on Vercel. Ok! Let's just do the same trick as we did for the dev server, and make an HTTP request.
This is fine enough for perf because we're caching this result locally to the function, plus it should be a fast CDN-cached response anyway.
Size upgrade, wowie! (I figure sharing services probably prefer a higher-resolution image, they're not very big, and to then scale them down for the application-specific use case & device.)
Meta tags are a bit tricky in apps built with `create-react-app`! While some bots like Google are able to render the full page when crawling, not all bots are. Most will just see the empty-ish index.html that would normally load up the application.
But we want outfit sharing to work! And be cool! And use our new outfit thumbnails!
In this change, we add a new server-side rendering API route to handle `/outfits/:id`.
It's very weak server-side rendering: it just loads index.html, and makes a few small tweaks inside the `<head>` tag. But it should be enough for sharing to work in clients that support the basics of Open Graph, which I think most major providers respect! (I know Twitter has their own tags, but it also respects the basics of OG, so let's see whether there's anything we end up _wanting_ to tweak or not!)
