I'm gonna also use this for a task to try to warm up *all* the
manifests in the database! But to start, just a simple one, to prepare
the alt styles page quickly on first run. (This doesn't really matter
in production now that I've already visited the page once, but it helps
when resetting things in dev, and I think more it's about establishing
the pattern!)
The Neopets Media Archive is a service that mirrors `images.neopets.com`
over time! Right now we're starting by just loading manifests, and
using them to replace the hacks we used for determining the Alt Style
PNG and SVG URLs; but with time, I want to load *all* customization
media files, to have our own secondary file source that isn't dependent
on Neopets to always be up.
Impress 2020 already caches manifest files, but this strategy is
different in two ways:
1. We're using the filesystem rather than a database column. (That is,
manifest data is kinda duplicated in the system right now!) This is
because I intend to go in a more file-y way long-term anyway, to
load more than just the manifests.
2. Impress 2020 guesses at the manifest URLs by pattern, and reloads
them on a regular basis. Instead, we use the modeling system: when
TNT changes the URL of a manifest by appending a new `?v=` query
string to it, this system will consider it a new URL, and will load
the new copy accordingly.
Fun fact, I actually have been prototyping some of this stuff in a side
project I'd named `impress-media-server`! It's a little Sinatra app
that indeed *does* save all the files needed for customization, and can
generate lightweight lil preview iframes and images pretty easily. I
had initially been planning this as a separate service, but after
thinking over the arch a bit, I think it'll go smoother to just give
the main app all the same access and awareness—and I wrote it all in
Ruby and plain HTML/JS/CSS, so it should be pretty easy to port over
bit-by-bit!
Anyway, only Alt Styles use this for now, but my motivation is to be
able to use more-correct asset URL logic to be able to finally swap
over wardrobe-2020's item search to impress.openneo.net's item search
API endpoint—which will get "Items You Own" searches working again, and
whittle down one of the last big things Impress 2020 can do that the
main app can't. Let's see how it goes!
