The 2020 Next.js rewrite, now being merged into impress!

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. |

Dress to Impress 2020
This is a rewrite of the Neopets customization app, Dress to Impress!
It's a React app, built with create-react-app, running on Vercel, JAMstack-style.
The motivating goals of the rewrite are:
- Mobile friendly, to match Neopets's move to mobile.
- Simple modern tech, to be more maintainable over time and decrease hosting costs.
If you want to contribute, please reach out to Matchu! This repository is almost shareable, but the main limitation is that we currently run even our development server against the production database, and those credentials are private. But we can change that if there's interest!
Architecture sketch
First, there's the core app, in this repository.
- React app: Runs on Vercel's CDN. Code in
src/app. - API functions: Run on Vercel's Serverless Functions. Code in
apiandsrc/server.
Then, there's our various data storage components.
- MySQL database: Runs on our Linode VPS, colocated with the old app.
- Amazon S3: Stores PNGs of pet/item appearance layers, converted from the Neopets SWFs. (Once Neopets releases HTML5-compatible assets for all their items, we can hopefully remove this!)
Finally, there's our third-party integrations.
- Auth0: For authentication. Data imported from our old OpenNeo ID auth database.
- Honeycomb: For observability & performance insights on the backend.
- Discord: For logging Support users' actions to a private Discord server.
- Neopets: We load pet data from them! And plenty of assets!
Notable old components not currently included in Impress 2020:
- Elasticsearch: Used for lightning-fast item search queries. So far, we're finding the MySQL queries to be fast enough in practice. Might consider using some kind of fulltext query engine if that doesn't scale with more users!
- Resque: Used to schedule background tasks for modeling and outfit thumbnails.
- Outfit thumbnail generation: Used for outfit thumbnails in the app. I'm wondering if there's a way to get away with not doing this, like just rendering the layers... but I suppose if we want a good social share experience, then we'll probably want this. Maybe we can generate them on the fly as API requests, instead of adding a data storage component?
- Memcache: Used to cache common HTML and JSON snippets. Not yet needing anything similar in Impress 2020!
- The entire old Rails app! No references to it in here, aside from some temporary URL links to features that aren't implemented here yet.
