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

When I woke up this morning, the app had crashed because the mysql connection was closed! I'm not sure, why that caused a _crash_? Or why pm2 didn't pick up on it, and said the process was still online? (Maybe the process was running, but the server had stopped?) Those could be good to investigate?… …but better than diving too far into the details, is to just address the high-level problem: if the app goes down for unexpected reasons, I want it back up!! lol In this change, we add `monit`, a solid system for monitoring processes (including checking for behavior, like responding to net requests), and configure it to watch the app process and the nginx process. To test, you can run `pm2 stop impress-2020`, or `systemctl stop nginx`, to see that Monit brings them back up within seconds! This does add some potential surprise if you're _trying_ to take the processes down. The easiest way is to send the stop command through monit, like `monit stop nginx`. This will disable monitoring until you start it again through monit, I think? (You can also disable/enable monitoring as a direct command, regardless of app state.) |

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.
